Why does unicellular life divide?

Answer 4

Asexual reproduction

Question 5

What makes big cells inefficient?

Answer 5

Too much volume too little surface area

Question 6

How is cell efficiency determined?

Answer 6

By its surface area to volume ratio

Question 7

Why does multicellular life divide?

To grow and heal

Question 8

What part of a cell actually divides during mitosis?

Answer 8

DNA actually divides

Question 9

What is another name for mitosis

Answer 9

Mitotic phase

Question 10

What happens to a cell during prophase?

Answer 10

The DNA condenses, organizes and the chromosomes structure appears

Question 11

Why do chromosomes become visible during prophase?

Answer 11

Because DNA condenses

Question 12

What is the cell cycle?

Answer 12

An ordered series of events in the life of a eukaryotic cell

Question 13

Interphase?

Answer 13

The stage during which cell carries out its metabolic processes and performs it’s functions

Question 14

What is the order of the phases

Answer 14

Prophase
Metaphase
Anaphase
Telophase

Question 15

During G1 what is the cell doing?

Answer 15

Cell grows

Question 16

What is being duplicated during S phase?

Answer 16

The genetic material (DNA & chromosomes)

Question 17

What happens on the g2 phase?

Answer 17

The cell prepares for division by making copies of its organelles such as mitochondria and chloroplasts

Question 18

What happens during the mitotic phase

Answer 18

Chromosomes divide

Question 19

What happens during cytokinesis

Answer 19

Cytoplasm divides

Question 20

Examples of when something is in G1 but eventually stop growing

Answer 20

Nerve & heart cells

Question 21

What must DNA be passed to?

Answer 21

Daughter cells

Question 22

When is DNA copied

Answer 22

S phase

Question 23

When do chromosomes form?

Answer 23

During g2 because nda spools around histones (exceptionally emall proteins)

Question 24

Describe how chromosomes form

Answer 24

1. Chromosomes duplicate 2. Creates sister chromatids 3. Identical chromosomes separate and ate distributed to two daughter cells

Question 25

What happens in prophase?

Answer 25

Chromosomes finish forming sister chromatids. Spindle fibers form

Question 26

What are spindle fibers?

Answer 26

Made of microtubules

Question 27

What do spindle fibers do?

Answer 27

Stretch from pole to pole & eventually connect the centromere of the chromosome

Question 28

What 2 cell parts break down during prophase?

Answer 28

Nuclear envelope and nucleolus

Question 29

Where are microtubules arranged in a ring formed?

Answer 29

Animal cells

Question 30

What is the function of microtubules

Answer 30

Helps form cytoskeleton & spindle fibers

Question 31

What happens during g2

Answer 31

Asters form and centrioles replicate

Question 32

Asters

Answer 32

Short microtubules in patter around the centriole | Acts as a substitute cytoskeleton only in animal cells

Question 33

What happens in metaphase

Answer 33

Spindle fibers move chromosomes to the equator

Question 34

Anaphase is what stage

Answer 34

3rd stage (away, apart)
