Unit 2 reproduction

Question 1

Why is there variation

Answer 1

Fetilisation is random process involving chance

Question 2

Gamates

Answer 2

Multicellular organisms produce sex cells called gamates

Question 3

In flowering where are gamates produced

Answer 3

In the flower

Question 4

Male gamates in flowering plants are found

Answer 4

Inside pollen grains made in the anthers of the flower

Question 5

Female gamates in flowering plant

Answer 5

Inside ovules in overlies of flower

Question 6

Male animal gamates

Answer 6

Sprem cells made in testies

Question 7

Sperm cells

Answer 7

Have a tail to swim to the egg

Question 8

Female gamates animals

Answer 8

Ova made in overies

Question 9

Fertilisation

Answer 9

Fusion of 2 haploid gamates to produce a diploid zygote, which divides to form an embryo

Question 10

Diploid

Answer 10

Contains 2 matching sets of chromosomes

Question 11

Haploid cells

Answer 11

Contain 1 set of chromosomes

Question 12

Anthers

Answer 12

Organ within a flower that produces pollen grains

Question 13

Overies

Answer 13

Female sex organs

Question 14

Pollen grains

Answer 14

Structure produced in anthers of a floe and contain male gamates

Question 15

Pollination

Answer 15

Trasfer of a pollen grain from anthers to stigma, usually by wind or animal pollinater

Question 16

Testes

Answer 16

Production of sperm

Question 17

Zygote

Answer 17

Fertilised egg cell

Question 18

How are dipod cells maintained as organisms grow

Answer 18

Mitosis

Question 19

Why are boys cells diploid and gamates haploid

Answer 19

Gamates are haploid so that fertilisation restores a diploid state
