Question 1

what is reproduction?

Answer 1

the act of producing offspring (baby/embryo/zygote)

Question 2

what are the two types of reproduction

Answer 2

asexual
sexual

Question 3

what is sexual reproduction

Answer 3

when 2 organisms/parents of the same species come together to reproduce a new individual- through the diffusion of gametes (sex cells)

Question 4

what is asexual reproduction?

Answer 4

when one organism reproduces offsprings on its own, without gamete diffusion

Question 5

list 4 advantages of asexual reproduction

Answer 5

• plants will be able to reproduce similar organisms for the environment and humans
• the process is usually rapid because it doesn’t involve gametes
• the organism doesn’t have to try to find a partner to reproduce with - this allows reproduction to occur often and faster.
• the process of fertilization and embryo development doesn’t take place, hence the process is not long.

Question 6

list 2 advantages of sexual reproduction

Answer 6

• allows variation in genetic patterns in the organisms for individuality
• the traits of an individual will become stronger, and will be able to adapt to a new environment and colonize new habits more successfully

Question 7

list 4 disadvantages of asexual reproduction

Answer 7

• time and energy is needed
• failure of reproduction
• genetic diseases can be passed on to offsprings
• takes longer for the organism mature

Question 8

list the 4 stages of binary fission

Answer 8

1. parent cell
2. replication of DNA
3. segregation/splitting of DNA
4. cell splitting into two identical daughter cells
