STEM 5 - Cell Cycle and Mitosis

produce identical cell

produce identical cell

main goal of mitosis is to_______

reproduction

main goal of meiosis is for______

somatic cell

what do you call the cell in Mitosis?

gametes cell

what do you call the cell in Meiosis?

body cell

somatic cell is a_____

sex cell

gametes cell is a _____

eukaryotic cell

mitosis happens in

regeneration

the ability to replace lost or damaged body parts

regeneration

it does not happen to human

cell division

the process by which a parent cell divides into two or more.

Mitosis

part of the cell cycle when replicated chromosomes are separated.

Interphase

preparation

Prophase

2 rounds preparation

centrosome

This mitotic spindle involved in this process originates from the_____

centrioles

centrosome, which is composed of paired_____

interphase

centrioles that have been duplicated during____

prometaphase

the transition stage from prophase to metaphase is known as_____

during prometaphase

the nuclear envelope starts to break down allowing the spindle to interact with the chromosomes

cell division

all types of cells have the ability to reproduce through_____

metaphase

equilibrium ‘‘central’’ positioning of the chromosomes

equilibrium ‘‘central’’ positioning of the chromosomes

means that one of the sister chromatids has an attached spindle fiber on one centrosome and the other sister chromatid is attached to the other centrosome and the other sister chromatid is attached to the other centrosome

anaphase

next stage of mitosis wherein sister chromatid separates and moves apart toward the opposite poles of the cell. as the poles move further apart, the cell elongates the spindle.

telophase

begins when the chromosomes at the end of each pole decondense. A new nuclear envelope forms and chromosome further decondenses into a chromatin,

telophase

produce two daughter cell, forming a cleavage

repair and healing of damage tissue

why do cell have to undergo cell growth cycle processes? (first reason)

replication of genetic materials

why do cell have to undergo cell growth cycle processes? (second reason)

reproduction of species

why do cell have to undergo cell growth cycle processes? (third reason)

sperm and egg cell

what do you call the gametes cell in a human body

meiosis

consists of two sets of cell division

Meiosis 1 and Meiosis 2

if meiosis consists of two sets of cell division then what are the two sets called____

cytokinesis should take place

in order to finally create two new cells______

during anaphase

cytokinesis is initiated during what phase______

barrel-shaped

in plant cells, due to the absence of centrosome in plants, the fibers are ______ instead of spindle shaped.

membrane vesicles

are then produced from the phragmoplast which travel or slide across the fiber to form a new sheet of cytoplasmic membrane which known as cell plate.

cell plate

membrane vesicles are then produced from the phragmoplast which travel or slide across the fiber to form a new sheet of cytoplasmic membrane which known as____

cell plate

then thickens and separates the two new cells.

during prophase

what phase that a plant decides at which plane the new plate will form.

G1 phase

‘‘decision making step’’

G1 phase

cell decides if it will start the cell cycle or rest or permanently exit the cell cycle to become a differentiated cell.

S phase

if the cell decides to pass through G1 phase then it will commit to undergo the______

S phase

DNA replication occurs where the nucleus become larger with twice the amount of DNA.

Synthesis (S phase)

DNA replication commences resulting in each chromosome having two chromatids.

G2 phase

is where further growth and final preparation for mitosis happen

Gap 2 phase (G2 phase)

cells continue to grow and protein synthesis continues in preparation for mitosis.

because of mitosis

why do animals shred skin?

interphase

no cell division, preparation, resting

Cytoplate

breaking of cytoplasm

because of mitosis

our wound heals because of?

Yes

Is it possible for the cell to stop dividing?

abnormal cell growth resulting to cancer cells

if the cell continue to divide what would be the cell condition?
