Activity No. 04
MITOSIS
Cellular activities maintain the life of the cell. However, as somatic cells are damaged, discased or worn
out, they are replaced by cell division, a process whereby the cells reproduce themselves. Somatic cell division,
or mitosis, involves a cytoplasmic division called cytokinesis to produce two identical cells. Each cell produced
has the same number and kind of chromosomes as the cell from which they were derived.
Through mitosis, dead or injured cells are replaced and also, new cells are added
tissue/organ
growth. The mitotic phase of the cell cycle in somatic cells involves two steps:
1. Nuclear division (karyokinesis)
2. Cytoplasmie division (cytokinesis)
The entire process results in the exact partitioning of the genetic material.
OBJECTIVES:
The students should be able to
1. Illustrate, identify and describe the different stages of mitosis in order to:
a. Show the cellular and chromosomal changes which occur in somatic cells
b. Determine the significant consequences of mitosis in terms of heredity based on changes during
the process
MATERIALS
Pencil, crayons
Allium cepa (onion) root tip undergoing cell division
Compound microscope
PROCEDURE:
a. Obtain slide of Allium cepa (onion) root tip 1.s. Under low power objective, locate the following regions:
root cap and meristematic region.
b. With the focus on the meristematic region of the root tip, switch to high power and examine cells at
various stages of mitosis.
c. Draw a representative cell for each mitotic stage. Label the visible cellular parts
The attuched pictures were obtained from google. The pictures contain onion cells undergoing cell
division at different stages. They were attached randomly together with this worksheet so you are
going to study the pictures to what stage of mitosis the onion cells are. I chose to take pictures
online for better and clearer image. Thus, if you search more about the pictures, you will have
greater chance of doing your activity correctly. In this case, I will focus more on checking if you
have labeled the visible cellular parts properly.
