 Lesson The Different Types of Cells
There are different types of cells among organisms which could vary in shapes
and sizes. These tiny structures are the basic unit of all living things. Cells
comprise tissues, tissues make up organs, organs form organ systems, and organ
systems work together to create an organism.

Activity 2.2: Comparison Between a Prokaryotic Cell and a Eukaryotic Cell

Picture Analysis: Examine the figures below. Observe the parts of a prokaryotic cell and
a eukaryotic cell. Please be guided of the guide questions provided.

Figure 1. Eukaryotic Cell (Animal Cell)

Figure 2. Prokaryotic Cell

 Based from the picture examined:
1. What parts of a cell are common to a prokaryotic cell and a
eukaryotic cell?
2. What are the distinguishing parts of a prokaryotic cell that are
not present in a eukaryotic cell?
3. In terms of structure, which among the two cells is more
complicated? Why?

What is It

There are several distinguishing features between a eukaryotic cell and a

prokaryotic cell. One of the major differences between prokaryotic and eukaryotic cells is
the location of their DNA. In a eukaryotic cell, most of the DNA is in an organelle called
the nucleus, which is bounded by a double membrane. In a prokaryotic cell, the DNA is
concentrated in a region that is not membrane-enclosed, called the nucleoid. Eukaryotic
means “true nucleus” (from the Greek eu, true,and karyon, kernel, referring to the
nucleus), and prokaryotic means “before nucleus” (from the Greek pro, before), reflecting
the earlier evolution of prokaryotic cells.
The interior of either type of cell is called the cytoplasm; in eukaryotic cells, this
term refers only to the region between the nucleus and the plasma membrane. Within the
cytoplasm of a eukaryotic cell, suspended in cytosol, are a variety of organelles of
specialized form and function. These membrane-bounded structures are absent in
prokaryotic cells, another distinction between prokaryotic and eukaryotic cells. However,
despite the absence of organelles, the prokaryotic cytoplasm is not a formless soup of
cytoplasm but appears to be organized into different regions.
Eukaryotic cells are generally much larger than prokaryotic cells. Size is a general
feature of cell structure that relates to function. The logistics of carrying out cellular
metabolism sets limits on cell size. At the lower limit, the smallest cells known are bacteria
called mycoplasmas, which have diameters between 0.1 and 1.0 μm. These are perhaps
the smallest packages with enough DNA to program metabolism and enough enzymes
and other cellular equipment to carry out the activities necessary for a cell to sustain itself
and reproduce. Typical bacteria are 1–5 μm in diameter while eukaryotic cells are typically
10–100 μm in diameter.

A prokaryotic cell does not have a true nucleus. DNA is in

an unbound region called the nucleoid. It does not have membrane
bound organelles too. Single – celled organisms under Domain
Bacteria and Domain Archaea have prokaryotic cells. They are
called prokaryotes.
A eukaryotic cell is a type of cell with membrane-enclosed
nucleus and organelles. Organisms under Domain Eukarya
(protists, fungi, plants, and animals) have eukaryotic cells. They
are called eukaryotes.
 Let us try to plot the distinguishing features of a eukaryotic cell versus a
prokaryotic cell. (Please refer to Figure 1 and 2.)

Table 1. Distinguishing Features of a Eukaryotic Cell vs. Prokaryotic Cell

Cell division It undergoes mitosis. It undergoes binary fission.

Cytoplasm It contains organelles and Organelles and

cytoskeleton. cytoskeleton are absent.
Few ribosomes are
present.

Representative Organisms protists, fungi, plants, and Bacteria, Archaea

animals (thermophiles, cryophiles,
halophiles)

Can you now clearly distinguish eukaryotic cells from prokaryotic cells? Let us
learn more about eukaryotic cells and identify the different types of tissues and cells of
plants and animals. Can you recall what makes a plant cell different from an animal cell?
A plant cell contains a rigid cell wall, plastids, vacuole, fixed regular shape, and stores
excess glucose as starch. An animal cell stores excess glucose as glycogen, have
centrioles, and generally have an amorphous shape.
Table 2. Common Types of Animal Cells and Its Functions
Cell Type Functions
1. Skin Cells

a. melanocytes • produces the hormone melanin which is responsible

for skin pigmentation(color) and photoreception of the
skin and eyes
b. keratinocytes • generates a protein called keratin which helps make
the skin an effective layer of protection for the body
• fibrous structural protein of hair, nails, horn, hoofs,
wool, feathers, and of the epithelial cells in the
outermost layers of the skin
2. Muscle Cells • responsible for the contraction and relaxation of
(myocytes) various organs (heart, lungs, liver, stomach) which is
necessary to live.
3. Blood Cells

a. Leukocytes (WBC) • plays a significant role in immune responses – an

activity done to fight against foreign bodies that may
enter the body.
Examples:
• Fever is an immune response of infections caused by
interleukin – a type of WBC.
• Allergic reaction is an immune response caused by
histamine.
b. Erythrocytes • carry oxygen as it binds with hemoglobin from the
(RBC) lungs to the body tissues and carbon dioxide as a
waste product, away from the tissues and back to the
lungs
• circulate around the body for 120 days and will be
removed from circulation by the macrophages – a
phagocyte – from the spleen and the liver
c. Thrombocytes • prevent bleeding due to the proteins on their surface
(platelets) that allow them to stick to breaks in the blood vessel
wall and to stick to each other
• contain granules that can release other proteins
required for creating a firm plug to seal blood vessel
breaks.
4. Nerve Cells • receive sensory input from the external world, send
(neurons) motor commands to the muscles, and transform and
relay the electrical signals at every step in between
a. Glial Cells • supportive cell in the central nervous system which
do not conduct electrical impulses unlike neurons
• surround neurons and provide support for and
insulation between them
5. Fat Cells • store energy in the form of fat, cushion internal
(adipocytes) organs, and kept the body warm(insulation) which is
found in the subcutaneous layer under the skin;
around the heart, kidneys, and nerve tissue; in
yellow bone marrow and breast tissue; and within the
buttocks, thighs, and abdominal cavity
 6. Bone Cells • responsible for locomotion (movement), support and
protection of soft tissues, calcium and phosphate
storage, and the harbor of bone marrow

Cancer Cells

Unlike all of the other cells listed, cancer cells work to destroy the body. Cancer
results from the development of abnormal cell properties that cause cells to divide
uncontrollably and spread to other locations. Cancer cell development can originate
from mutations stemming from exposure to chemicals, radiation, and ultraviolet light.
Cancer can also have genetic origins such as chromosome replication errors and cancer-
causing viruses of the DNA.
Cancer cells can spread rapidly because they develop decreased sensitivity to
anti-growth signals and proliferate quickly in the absence of stop commands. They also
lose the ability to undergo apoptosis or programmed cell death, making them even more
formidable.

Stem Cells
Stem cells are unique in that they originate as unspecialized cells and can develop
into specialized cells that can be used to build specific organs or tissues. Stem cells can
divide and replicate many times in order to replenish and repair tissue. In the field of stem
cell research, scientists take advantage of the renewal properties of these structures by
utilizing them to generate cells for tissue repair, organ transplantation, and for the
treatment of disease.
 Like animals, plants are multicellular eukaryotes which are composed of organs,
tissues, and cells with highly specialized functions. There are two types of plant tissues:
meristematic tissue and permanent (or non-meristematic) tissue. Meristems produce
cells that quickly differentiate, or specialize, and become permanent tissue. Such cells
take on specific roles and lose their ability to divide further. They differentiate into three
main tissue types: vascular, dermal, and ground tissue.

Table 3. Common Types of Plant Tissues/ Cells and Its Functions

Tissue/ Cell Type Functions

1. Vascular Tissue • transports substances like water, minerals, and

sugar from one extreme end of the plant to the other
a. Xylem Tissue • water conducting cells
• transports water and nutrients from the plant–soil
interface to the stems and leaves
• provides mechanical support of the water
transported upward and the plant itself
b. Phloem Tissue • acts as a transport system for soluble organic
compounds within vascular plants
• move sucrose sugar and proteins from the leaves
where they are produced through photosynthesis to
the rest of the plant
2. Dermal tissue • covers and protects the plant, and controls gas
exchange and water absorption (in roots)
• prevents evaporative water loss in the stem and
leaves of plants due to the presence of a waxy
covering called cuticle
3. Ground tissue • carries out different functions based on the cell type
(parenchyma, collenchyma, and sclerenchyma) and
the location in the plant
a. Parenchyma cells • make up plant leaves and is the site of
photosynthesis, thus, contains large quantities of
chloroplast
• sites of sugar or starch storage in roots and are
called pith (in the root center) or cortex (in the root
edges).
b. Sclerenchyma • provide structural support in growing regions of the
cells shoot system being long with thin cells that retain the
ability to stretch and elongate
c. Collenchyma cells • provide structural support in mature stems after
growth has stop due to its toughness and inability to
stretch
 Parenchyma

Sclerenchyma

Figure 2. The Different Types of Plant Cells/ Tissues

Did you know that…

Meristem
Meristem, region of cells capable of division and growth in plants. Meristems are
classified by their location in the plant as apical (located at root and shoot
tips), lateral (in the vascular and cork cambia), and intercalary (at internodes,
or stem regions between the places at which leaves attach. There are three primary
meristems: the protoderm, which will become the epidermis; the ground meristem,
which will form the ground tissues comprising parenchyma, collenchyma,
and sclerenchyma cells; and the procambium, which will become the vascular tissues
(xylem and phloem). Unlike most animals, plants continue to grow throughout their entire
life span because of the unlimited division of meristematic regions.
