REPRODUCTION IN FLOWERING PLANTS
Reproduction: Ability of organisms to produce a new generation

Two types:

• Asexual: Production by 1 parent

• Sexual: Production by 2 parents



• Asexual:

- 1 parent

- One stage (mitosis)

- No gametes formed

- O spring genetically identical (no variation)

- Thrive in stable environment

- Fast process

- More energy e cient

- No outside agents needed

- Can't adapt to environment easily

- Low possibility of evolution (no genetic variation)



• Sexual:

- 2 parents (di erent genders)

- 2 stages (meiosis & fertilisation)

- Gametes formed

- O spring are genetically di erent to parents

- Can adapt to changing environment

- Slow process

- Less energy e cient

- Pollinators often needed

- High possibility of evolution

, • Advantages of asexual reproduction:

- All individuals can produce o spring

- Process is simple & fast

- Useful in unchanging conditions

- Favourable mutation can spread rapidly

• Disadvantages of asexual reproduction:

- No gametic variation

- Overcrowding may occur



• Advantages of sexual reproduction:

- Variation

- Basis of evolution

- Better chance of survival in unstable environments

- Prevent spread of disease

• Disadvantages of sexual reproduction:

- High expenditure of energy

- Slower process

- Unfavourable mutations expressed

- Outside agents needed



• Sexual reproduction process:

- Diploid parent produces gametes (haploid cells) in gonads by meiosis

- Male & female gametes brought together by pollination (plants) or mating (animals)

- Gamete nuclei fuse = fertilisation

- New zygote cell is diploid

- Zygote grows by mitosis
