Mitosis And Meiosis

Question 0

Smaller cells have more surface area and can exchange materials across membrane more efficiently than larger cells

Answer 0

Surface area

Question 1

Why do cells divide rather than grow in size?

Answer 1

• surface area

- DNA overload

Question 2

The larger the cell, the greater the demands on the DNA content of the cell. Eventually, the cells DNA would no longer be able to serve the increasing needs of the growing cell

Answer 2

DNA “overload”

Question 3

It has

• centromere
• chromatids

Answer 3

The chromosome structure

Question 4

What the chromosomes attach them selves to during mitosis

Answer 4

Spindle fibers

Question 5

What are the four mitosis stages

Answer 5

Prophase, metaphase, anaphase, telophase

Question 6

When the cell replicates

Answer 6

Interphase

Question 7

Why do cells divide

Answer 7

• growth
• repair
• regeneration

Question 8

The events a cell goes through as it grows and divides

Answer 8

Cell cycle

Question 9

• the chromosomes become visible
• the centrioles separate and spindle fibers begin to form
• the nuclear membrane breaks down

Answer 9

Prophase

Question 10

Small organelles

Answer 10

Centrioles

Question 11

• the chromosomes line up across the center of the cell

- each chromosomes is connected to a spindle fiber

Answer 11

Metaphase

Question 12

• the spindle fibers separate the chromatids into individual chromosomes and they are moved apart

Answer 12

Anaphase

Question 13

• the chromosomes gather at opposite ends of the cell
• two nuclear membranes form
• the chromosomes lose their distinct shape

Answer 13

Telophase

Question 14

-the cytoplasm pinches and two cells are formed

Answer 14

Cytokinesis

Question 15

Two daughter cells with the same number and type of chromosomes

Answer 15

End result of mitosis
