Mitosis And Mieosis

Question 1

What is interphase?

Answer 1

Period of growth between cell divisions

Interphase is crucial for cell growth and preparation for division.

Question 2

What is the cell cycle?

Answer 2

The series of events that cells go through as they grow and divide

The cell cycle includes phases that ensure proper cell division and function.

Question 3

List the four phases of the cell cycle.

Answer 3

• G1 (Gap 1)
• S (Synthesis)
• G2 (Gap 2)
• M (Mitosis)

Each phase has specific functions and processes critical for cell division.

Question 4

What occurs during the G1 phase?

Answer 4

• Increase in size
• Synthesis of new proteins and organelles
• Chromosomes are replicated

G1 is the first gap phase and is essential for preparing the cell for DNA synthesis.

Question 5

What happens during the S phase?

Answer 5

DNA synthesis takes place

This phase is where the cell duplicates its DNA in preparation for mitosis.

Question 6

What is the purpose of the G2 phase?

Answer 6

• Organelles and molecules required for cell division are made

G2 is the second gap phase, ensuring the cell is ready for mitosis.

Question 7

What does the M phase consist of?

Answer 7

Mitosis

Mitosis is the process of cell division that results in two daughter cells.

Question 8

What is the function of spindle fibers?

Answer 8

To help separate chromosomes during cell division

Spindle fibers are critical for ensuring that each daughter cell receives the correct number of chromosomes.

Question 9

True or False: The G1 phase is the only phase where DNA is synthesized.

Answer 9

False

DNA synthesis occurs during the S phase, not G1.

Question 10

Fill in the blank: The series of events that cells go through as they grow and divide is called the _______.

Answer 10

cell cycle

Understanding the cell cycle is essential for studying cellular processes and growth.

Question 11

Prophase

Answer 11

Largest phase of mitosis
Central’s move to opposite ends of cell
Spindle fibers are produced
Chromosomes condense
Nuclear membrane starts to dissolve

Question 12

Metaphase

Answer 12

Chromosomes lineup at the metaphase plate
Spindle fibers connect to each side of centrioles

Question 13

Anaphase

Answer 13

Sister cremates pulled away from each other to opposite sides of the cell

Question 14

Cytokinesis

Answer 14

Cytoplasm pinches in half
Each daughter cell has identical cell of chromosomes
And plant cell plate forms between nuclei and becomes new cell wall

Question 15

Cell division

Answer 15

Processes when a cell divides into two new data cells, the cells volume is reduced when it is divided and eukaryote cell division is in two major stages

Question 16

What are the two major stages of cell division and what do they do?

Answer 16

Mitosis divides the nucleus
Cytokinesis the division of cytoplasm

Question 17

What are chromosomes?

Answer 17

Structures that passes genetic information from one generation to another

Question 18

What is interphase?

Answer 18

Period of growth between cell divisions

Question 19

What is the term for a cell with two sets of chromosomes?

Answer 19

Diploid (2n)

Question 20

What does ‘n’ represent in genetics?

Answer 20

The number of sets of chromosomes

Question 21

What are the two main stages of meiosis?

Answer 21

Meiosis I and Meiosis II

Question 22

What is the importance of variation in populations?

Answer 22

It is the raw material for natural selection

Question 23

What are the three sexual sources of genetic variation?

Answer 23

• Crossing over (prophase I)
• Independent assortment
• Random fertilization

Question 24

Fill in the blank: The process of meiosis results in _______ cells.

Answer 24

haploid

Question 25

True or False: Meiosis occurs in somatic cells.

Answer 25

False
