Asexual and Sexual Reproduction

Question 1

what is asexual reproduction

Answer 1

process resulting in the production of genetically identical offspring from one parent

Question 2

advantage of asexual reproduction

Answer 2

• only one parent needed
• no time and energy spent on finding mate
• reproduction occurs quickly
• less time and energy needed
• no genetic variation: crop farming

Question 3

disadvantage of asexual reproduction

Answer 3

no genetic variation - more susceptible to pathogens + vulnerable to environment changesno genetic vatiation, can’t adapt to change (if new disease -> all die)

Question 4

features of sexual reproduction

Answer 4

• two parents
• gametes
• fertilization
• plants, fungi, animals
• zygote
• meiosis
• variation
• evolution possible

Question 5

features of asexual reproduction

Answer 5

• one parent
• no gametes
• no fertilization
• plants, simple animals
• no zygote
• mitosis
• no variation
• no evolution possible
• rapid

Question 6

what is sexual reproduction

Answer 6

a process involving the fusion of the nuclei of two gametes to form a zygote and the production of offspring that are genetically different from each other

Question 7

All organisms that reproduce sexually produce sex cells called

Answer 7

gametes

Question 8

Fertilisation

Answer 8

fusion of the nuclei of
gametes

Question 9

advantages of sexual reproduction

Answer 9

• genetic variation
• more resistant to environment
• farmers can perform selective breedingvariation, more resistant to threats

Question 10

disadvantages of sexual reprodution

Answer 10

• time and energy to find mate
• time and energy
• slower
• involves two parents

Question 11

Are nuclei of gametes haploid or diploid?

Answer 11

haploid

Question 12

Is the nucleus of a zygote haploid or diploid?

Answer 12

diploid
