Module: Reproduction Flashcards
1
Q
what is reproduction?
A
the act of producing offspring (baby/embryo/zygote)
2
Q
what are the two types of reproduction
A
asexual
sexual
3
Q
what is sexual reproduction
A
when 2 organisms/parents of the same species come together to reproduce a new individual- through the diffusion of gametes (sex cells)
4
Q
what is asexual reproduction?
A
when one organism reproduces offsprings on its own, without gamete diffusion
5
Q
list 4 advantages of asexual reproduction
A
- 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.
6
Q
list 2 advantages of sexual reproduction
A
- 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
7
Q
list 4 disadvantages of asexual reproduction
A
- time and energy is needed
- failure of reproduction
- genetic diseases can be passed on to offsprings
- takes longer for the organism mature
8
Q
list the 4 stages of binary fission
A
- parent cell
- replication of DNA
- segregation/splitting of DNA
- cell splitting into two identical daughter cells
