- Plant Reproduction
- Sexual Reproduction
- Is the most common method of reproduction.
- it envolves two gametes
- There are two parents involved and it can be known as Fertilisation.
- Offspring reproduced this way have genetic variation.
- Fertilisation
- The process involves the fusion of a male and female gamete to prduce a zygote.
- The gametes undergo cell division and develops and embryo.
- The growth of the pollen tube in this process leads to seed and fruit formation.
- Seed Germination
- Germinating seeds utilise food reserves until the seedling can carry out photosynthesis by storing the food in the cotyledon.
- Conditions needed for seed germination are light, water, oxygen and the correct temperature.
- The structure of plants
- Insect Pollinated Plants.
- Plants have a strong scent, small anthers inside the plant, nectaries at the base of the plant to produce nectar, large stigmas and brightly coloured petals.
- Wind Pollinated Plants
- Plants have small pretals, no scent, many anthers which are long and large, no nectaries, small stigmas and green or tiny petals.
- Insect Pollinated Plants.

- Sexual Reproduction
- Doesn't need two parent cells.
- Cells from the parent cell divide to produce and identical clone.
