Sexual and Asexual reporuction

Question 1

Describe Sexual Reproduction

Answer 1

Sexual reproduction requires 2 parents and relies on Fertilisation (The fusion of gametes). Due to the fusion of the male gamete with the female gamete offspring show lots of genetic variation and look different from one another.

Question 2

Describe Asexual Reproduction

Answer 2

Asexual reproduction is reproduction with only one parent. Due to this there is no fertilisation this no fusion of gamete’s which means all offspring look identical and show no genetic variation.

Question 3

What is Reproduction?

Answer 3

Reproduction is a biological process by which new individual organisms are produced from their “parents”

Question 4

Describe the oviduct (its function)

Answer 4

It’s the site of fertilisation

Question 5

Question 6

describe the uterus (function)

Answer 6

It’s where the embryo will develop

Question 7

describe the vagina (function)

Answer 7

It’s where the sperm enters the female body

Question 8

Describe the cervix (Function)

Answer 8

Allows for fluid to pass between the vagina and uterus

Question 9

Describe the penis (function)

Answer 9

It’s the male organ used for sexual reproduction

Question 10

describe the urethra (function)

Answer 10

Carries sperm and urine out through the penis

Question 11

describe the sperm tubes (Function)

Answer 11

Question 13

What is the sexual reproduction organ in plants?

Answer 13

The flower

Question 14

what are make sex cells in plants and where are they produced?

Answer 14

male sex cells in plants are found in pollen grains and are produced in the anthers of the flower

Question 15

what are the female sex cells in plants and where are they produced?

Answer 15

The female sex cells are found in the ovules in flower and are produced in the ovary of the flower

Question 16

what is fertilisation?

Answer 16

Fertilisation is the fusion of nuclei of 2 gametes (sex cells).

Question 17

What is pollination?

Answer 17

Pollination is the transfer of pollen grain from the anther of one flower to the stigma of another.

Question 18

how can pollen be transferred?

Answer 18

Via insect/animal or by wind

Answer 19

Produces pollen grains (male sex sells)

Question 20
