Biology Chpt 10

Question 0

What is sexual reproduction?

Answer 0

Reproduction in which cells from two different parents join to form a new organism

Question 1

What is asexual reproduction?

Answer 1

A cell divides into two new daughter cells

Question 2

What is cell division?

Answer 2

Reproduction involving only one parent organism

Question 3

Why are cells limited from getting too large?

Answer 3

If surface area to volume ratio is small the cell will
have problems in getting food in and waste out, also more demand on DNA

Question 4

Why are cell division and reproduction important?

Answer 4

For many reasons like maintenance and making more
cells. Also the surface area to volume ratio will be larger which is better

Question 5

Although asexual and sexual reproduction both produce new offspring how do they differ?

Answer 5

Asexual
One parent
Two daughter cells
Identical Maintenance, healing wounds

Sexual
Two parents
Offspring have genetic material from both mom and dad
Reproduction

Question 6

What is the Cell cycle?

Answer 6

Series of events a cell goes through as it grows and divides

Question 7

Centromere

Answer 7

Area where two sister chromatids are attached.

Question 8

Chromatid

Answer 8

One of two identical “sister” parts of a replicated chromosome

Question 9

Chromosome

Answer 9

A combination of DNA and protein found in eukaryotic cells

Question 10

Cytokinesis

Answer 10

Part of the eukaryotic cell cycle during which the cytoplasm divides

Question 11

Interphase

Answer 11

Long period of the cell cycle between one cell division and the next

Question 12

Mitosis

Answer 12

Part of the eukaryotic cell cycle during which the nucleus divides

Question 13

Write the stages in prokaryotic cell division in order

Answer 13

Before division, the DNA forms one circle

Cell start to split into two daughter cells
Two daughter cells are formed

Question 14

The process of cell division in prokaryotic cells is called _________.

Answer 14

Question 15

Will the new cells have the same genetic material as the parent cell, or will each cell have
different genetic material?

Answer 15

Yes

Question 16

Answer 19

G1, S, G2

Question 20

The division of the cell nucleus during the M phase of the cell cycle is called ____________ .

Answer 20
