  • 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.

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