Lesson 1: Sexual/ Assexual reproduction Flashcards
1
Q
What is the main difference between the cells formed in mitosis vs the cells formed in meiosis?
A
- Mitosis: Idential cells are formed.
- Meiosis: Non-identical cells are formed.
2
Q
What does sexual reproduction involve in general ?
A
- Sexual reproduction involves the fusion (joining) of male and female gametes.
3
Q
What is being fused in animal sexual reproduction?
A
- Sperm and egg cells are being fused.
4
Q
What is being fused in plant sexual reproduction?
A
- Pollen and egg cells (in flowering plants.)
5
Q
How are gametes formed?
A
- Gametes are formed by “mieosis.”
- This means that every sperm/ egg cell are different to each other.
6
Q
Why is their variety in offspring in sexual reproduction?
A
- Because there is mixing of genetic information- this leads to variety in the offspring.
7
Q
How is assexual reproduction different to sexual reproduction?
A
- Assexual involves only one parent.
- No fusion of gametes.
- No mixing of genetic information.
- Mitosis rather than meiosis.
8
Q
In assexual reproduction, what are the offspring like?
A
- In assexual reproduction the offspring are genetically identical (clones.)
