Ch 30 (Pollination: act of placing pollen (containing male gametophyte) on…

- - - - self- compatibility: ability of plants to reject its own pollen and pollen of closely related individuals
      - some plants have stamens and carpels that mature at different times or are structurally arranged to discourage self-fertilization
      - some species lack either carpels or stamens in flowers
    - - ensures every ovule will develop into seed but decreases genetic diversity
- - - - Fragmentation: detached fragments of plants that can develop into a new plant
      - apomixis: plants can sometimes produce seeds without pollenation or fertilization
  - - - endosperm: food storing tissue of the seed
  - - - integument: envelopes and protects tissues that eventually give rise to female gametophyte
      - Megaspores: spores that produce female gametophyte
    - - microspores: spores that produce male gametophyte
        
        microspores develop pollen grain
      - pollen grain cam be transported from parent by wind or animal (abiotic or biotic pollenation) to the part of the plant that contains the ovule
