Previous Uses of Auxins Next Sexual Reproduction
  • Gats refer to male and female sex cells.
  • In animals, the male gat is the sperm cell, and the female gat is the egg cell.
  • Diagrams show sperm cells and egg cells (oum).
  • Gametes are produced in specific body parts: sperm in the testes and eggs in the ovaries.
  • Gametes are crucial for sexual reproduction because they are haploid, containing 23 chromosomes, half the number of a normal adult organism.
  • Fertilization restores the full chromosome number.
  • Flowering plants also produce male and female gametes.
  • Male pollen and female ex cells (ovules) are found in the flower head.
  • Plant gametes are important for exams, but detailed structure description of the flower is not necessary.
