Question 1

Cell division

Answer 1

Process in which cells divide into two new cells

Question 2

Asexual reproduction

Answer 2

Process in reproduction involving a single parent. This results in off-spring they are genetically identical to the parent.

Question 3

Three species that reproduce asexually

Answer 3

Bacterium, hydra, kalanchoe.

Question 4

Sexual reproduction

Answer 4

Type of reproduction in which cells from two parents unite to form the first cell of a new organism

Question 5

What is an advantage and disadvantage of asexual reproduction

Answer 5

1. They can reproduce quickly allowing them to compete with other organisms
2. a lack of genetic diversity

Question 6

Some species like yeast reproduce sexually and asexually. Why is this an advantage

Answer 6

It’s an advantage because you have the pro’s and the con’s which cancel out

Question 7

Chromosome

Answer 7

Threadlike structure within the nucleus that contains genetic information they is passed on from one generation to the next.

Question 8

How many chromosomes does a human cell have

Answer 8

46

Question 9

Chromatin

Answer 9

Substance found in eukaryotic chromosomes that consists of tightly coiled around histones.

Question 10

What happens during cytokinesis in animal cells

Answer 10

The cell membrane is drawn inward until the cytoplasm is pinched into nearly two equal parts.

Question 11

What happens during cytokinesis in plant cells

Answer 11

A structure known as the cell plate forms halfway between the divided nuclei. The plates gradually develops into cell membranes that separates the two daughter cells. A cell wall then forms in between the two membranes, completing the process.
