Asexual Reproduction and Sexual Reproduction Flashcards
What term is used to describe 1 set of chromosomes found in a normal cell of the body?
Haploid
How many chromosones does a sperm have?
23
How many chromosones does an ovum have?
23
What is the name of a human sex cell?
Gamete
What is reproduction?
The biological process by which new individual organisms (offspring) are produced from their parent/s
Give two reasons as to why reproduction is important
Reproduction is important because:
- All species must reproduce to survive.
- Organisms cannot live forever, so they must reproduce to allow their species to continue to live on.
How many parents does asexual reproduction involve?
1
How many parents does sexual reproduction involve?
2
Describe asexual reproduction
New offspring is produced by a single parent.
Describe sexual reproduction
It is where new individuals are produced by the fusing of the nucleus from the male and the female gametes.
What is the difference between asexually reproduced offspring and sexually reproduced offspring
- Asexually reproduced offspring are exactly identical to their parent (they are clones) while in sexual reproduction, two parents contribute genetic information to produce unique offspring.
Sperm + Ova = _______
Zygote
What is the name for a fertilised egg cell?
Zygote (Diploid)
How many chromosones does a zygote have?
46 (sperm and egg have 23 each and when they fuse during fertilisation they bond together, so 23+23=46.)
What does a zygote split into?
It splits into an embryo (small ball of cells)
