Cell division

Question 1

Cell division is…

Answer 1

a process by which a single cell produces two daughter cells

Question 2

Cell divison occurs for…

Answer 2

• Growth
• Cell replacement
• Healing
• Reproduction

Question 3

Binary fission

Answer 3

an asexual process where prokaryotes separate the parent cell into two daughter cells. It is a simpler and faster process than mitosis

Question 4

Prokaryotic cells divide by…

Answer 4

binary fisson

Question 5

Eukaryotic cells divide by..,

Answer 5

mitotic cell division

Question 6

The cell cycle consists of two different phases:

Answer 6

1. M phase
2. Interphase

Question 7

M phase

Answer 7

Mitosis
- The separation of the chromosomes into two nuclei
Cytokinesis
- The actual splitting of the two cells

Question 8

Interphase

Answer 8

S phase: DNA replication (twice as much DNA is produced)
G1 phase: Time preparation for the S-phase and regulatory proteins are created
G2 phase: Time preparation for the M phase and the cell size and amount of protein increases
G0: when the cell is not in a state of divison

Question 9

Cell division in a eukaryotic cell

Answer 9

• genome is larger and linear
• DNA is found in the nucleus
• reproduced by mitotic cell divison

Question 10

Cell division in a prokaryotic cell

Answer 10

• Genome is small and circular
• DNA is found in the cytoplasm
  -reproduced by binary fission

Question 11

Observations of embryos confirmed that plants and animals

Answer 11

• start as single celled organisms
• meiosis produces reproductive called gametes
• mitosis produces samatic cells
