Cellular Reproduction Test Review

the DNA is copied, a new cell membrane forms between the DNA copies, and the cell splits into two cells

in a bacterium, cell division takes place when..

G1→S→G2→M→C→

What is the correct sequence of the cell cycle?

has a complete set of 46 chromosomes

after m and c the 2 new cells have how many chromosomes?

receives an exact copy of all the chromosomes present in the original cell

As a result of mitosis, each of the two new cells produced from the original cell during cytokinesis

a cell’s nucleus divides

Mitosis is a process by which

yes

does cytokinesis differ in plant cells and animal cells?

goes up

what does a cancer cell graph look like?

the ratio of volume to surface area increases

what happens as a cell grows larger and larger?

12

If a cell has 12 chromosomes how many will each daughter cell have?

it isn’t specialized in structure and function

a stem cell has potential medical uses because it

chromosome

form of DNA needed for mitosis to occur

chromatid

name for the identical half of a replicated chromosome

mitosis

what stage involves the division of the nucleus

interphase

the cell grows, functions and copies its DNA during this stage

centromere

holds 2 sister chromatids together

cytokinesis

this stage involves the division of the cytoplasm

chromosome

tightly coiled form of DNA

chromatin

relaxed, uncoiled DNA

chromatin

form of DNA during interphase

daughter cells

new cells formed through mitosis

binary fission

reproduction of prokaryotic cells

G-0

when a cell exits the cell cycle to continue functioning by stops dividing

prophase

centrioles begin to form spindle fibers and move to opposite poles of the cell

interphase

DNA is in the form of chromatin

anaphase

spindle fibers shorten, pulling apart 2 sister chromatids into unreplicated chromosomes

S phase

DNA is copied

telophase

nuclear envelope reforms

prophase

chromatin coils into replicated chromosomes

centromere

protein disc that holds 2 sister chromatids together

metaphase

spindle fibers arrange replicated chromosomes along the middle of the cell

telophase

chromosomes uncoil and relax back into chromatin

cytokinesis

cell membrane starts to pinch in, forming a cleavage furrow

animal- cleavage furrow (cells pinch in before splitting)

plant- cell plate forms that splits it into 2 cells

cytokinesis difference in animal and plant

create more cells in our body + heal ourselves

why does mitosis occur?

small cells are better at communication and exchanging materials

\
large cells are bad bc their volume is bigger than their surface area and it means the cells cant function properly

why do we need small cells instead of a few large cells?
