Sexual and asexual reproduction

Question 1

Clone

Answer 1

Organism genetically identical to its parent

Question 2

Which plants reproduce asexually?

Answer 2

potato plants, spider plants, daffodils

Question 3

Which animals reproduce asexually?

Answer 3

sea anemones and star fish

Question 4

Asexual reproduction

Answer 4

Reproduction where each new organism contains identical genes which are genetically identical to the parent cell resulting in no variation.

Question 5

Sexual reproduction

Answer 5

Reproduction where offspring produced are not identical and therefore results in variation

Question 6

Gametes

Answer 6

sex cells used in sexual reproduction

Question 7

Fertilisation

Answer 7

where the male and female gametes (sperm and egg) fuse

Question 8

What are the advantages of asexual reproduction?

Answer 8

• If a parent is well adapted to an area the offspring will share an identical set of characteristics
• Only one parent is needed making reproduction faster and producing large numbers of offspring quickly

Question 9

What is the disadvantage of asexual reproduction?

Answer 9

adverse changes to the biotic or abiotic factors may destroy the species as all organisms will be affected

Question 10

What is the advantage of sexual reproduction?

Answer 10

Variation in offspring leads to adaptations in a species so so some organisms in a population will contain the adaptations required to cope with environmental pressures. These organisms can reproduce, enabling the population to continue.

Question 11

What is the disadvantage of sexual reproduction?

Answer 11

reproduction requires 2 parents so reproduction is slower and fewer offspring are produced
