1) What are the main features of a prokaryotic cell?
The main features of a prokaryotic cell are that they don’t have a membrane-bound
nucleus, are unicellular, have little cellular organization, and has a cell wall.
2) What are the main features of a eukaryotic cell?
The main features of a eukaryotic cell is that it has a membrane-bound nucleus,
chromosomes are contained in the nucleus, complex cell structure, and membrane-bound
organelles.
2b) Name examples of eukaryotic cells
● Human white blood cell
● Bone cells
● Red blood cells
3) Use the diagram of a plant cell in the previous stage to become familiar with the features
of a plant cell. Use the following list of terms to help you: nuclear membrane, cytoplasm,
endoplasmic reticulum, mitochondrion, starch granule, nucleus, vacuole, plasma
membrane, cell wall, chloroplast
(a) Cytoplasm
(b) Vacuole
(c) Starch Granuels
(d) Chloroplast
(e) Mitochondria
(f) Cell wall
(g) Chromosome
(h) Nuclear membrane
(i) Endoplasmic Reticulum
(j) Plasma membrane
4) Which features identify this plant cell as eukaryotic?
Some features that identify this plant cell as eukaryotic are that it has a membrane-bound
nucleus and it has membrane-bound organelles.
5) What is an organelle?
An organelle is part of a cell that performs various jobs/functions to help the cell survive.
6) Why are there so many different types of organelles in eukaryotic cells?
There are so many different types of organelles in eukaryotic cells because they have
different roles to play in the cell for it to survive and maintain homeostasis.
7) Name an organelle where photosynthesis occurs: Chloroplast
8) How many of these organelles are present in the labeled cell above?
9) Use the diagram of a plant cell in the previous stage to become familiar with the features
of a plant cell. Use the following list of terms to help you: cytoplasm, plasma membrane,
rough endoplasmic reticulum, mitochondrion, nucleus, centriole, golgi apparatus
(a) Plasma membrane
(b) Golgi apparatus
(c) Centriole
(d) Mitochondrion
(e) Lysosome
(f) Nucleus
(g) Rough endoplasmic reticulum
(h) Cytoplasm
10) Name the features on the cell above that identify it as an animal cell
Some features of the cell above that identifies it as an animal cell are that it has no cell
wall, it has lysosomes, centrioles, etc.
11) Where is the plasma membrane on the animal cell?
The plasma membrane is located on top of the animal cell enclosing the cell and its
organelles.
12) What is the function of the plasma membrane?
The function of the plasma membrane is that it blocks out unwanted substances from the
cell where it can potentially harm the cell.
13) Name the largest organelle visible on the animal cell above: Nucleus
14) What important material does this organelle contain?
The nucleus contains genetic material/DNA.
15) List the important components of the plasma membrane: Glycolipid, Channel protein,
Carrier protein, Glycoprotein
16) Identify which kidn of molecules on th diagram
a) Phosphate head
b) Fatty acid tail
17) Which end is attracted to water?
Phosphate head
18) List the organelles shown in the diagram above that have membranes: Golgi Body,
mitochondrion, ribosome, smooth endoplasmic reticulum, lysosomes
19) Give one example of how membranes are involved in compartmentalization?
One example is how cell membranes control the substances that move in and out of the cell.
20) Why is Compartmentalization important?
It is important because if the cell membrane does not control the materials/substances that pass
the other organelles will not be able to function if those needed substances are not being brought
or excreted.
21) Give one example of how membranes are involved in the transport of substances: One
example of how membranes are involved in the transport of substances is when CO2 needs to be
excreted. The cell membrane allows the CO2 to be passed out of the cell if it is not needed.
