MITOSIS

The document outlines the objectives of a lesson on mitosis, emphasizing its definition, phases, and significance to living organisms. Mitosis is described as a process of cellular reproduction that results in two identical daughter cells, crucial for growth and repair in somatic cells. The document details the stages of mitosis: prophase, metaphase, anaphase, telophase, and cytokinesis.

OBJECTIVES

At the of the lesson, the students should be able to:

a) Define mitosis and its importance


b) Identify and explain the different phases of mitosis as well
as their processes.
c) Elaborate the importance of mitosis to all living organisms.
Cells do not “grow” or become large,
rather, cells reproduce more cells.
Cellular reproduction is what makes our
bodies grow and develop. One type of
cellular reproduction is mitosis.
Cell Division- alternating with the interphase is the cell
division phase. In eukaryotic cells there are two types of
cell division: mitosis and meiosis.
Mitosis is a process that allows a cell to divide into two
identical daughter cells. It's a key part of the cell cycle
that helps organisms grow, develop, and repair
themselves.
Mitosis happens in the body cells or
somatic cells. Somatic cells are any cells
in the body that are not reproductive cells,
such as skin, muscle, and bone cells. It is
divided into 4 stages.
Prophase - is the first phase of cell
division, occurring in both mitosis
and meiosis. During prophase,
chromatin condenses into visible
chromosomes, and the mitotic spindle
begins to form.
PROPHASE
Metaphase is a phase of cell division
when chromosomes align in the middle
of a cell. It's the third phase of mitosis,
which is the process of separating
duplicated genetic material into two
identical daughter cells.
Anaphase- is a phase of mitosis when
duplicated chromosomes are separated
and moved to opposite ends of a cell. It's
the fourth phase of mitosis, which is the
process of separating duplicated genetic
material into two identical daughter cells.
Telophase - is the final stage of cell
division in mitosis and meiosis. It's
when a nuclear membrane forms
around each set of chromosomes,
separating the nuclear DNA from the
cytoplasm.
Cytokinesis is the process by which
a cell's cytoplasm splits into two
daughter cells. It's the final step of
cell division and occurs after the
duplication of genetic material.
