Practice: Sexual Reproduction in Plants

Miss Anderson is making a display about the process of sexual reproduction in plants. She writes down the stages:

  1. An insect enters a flower, and pollen from the anthers sticks to the insect’s body and legs.
  2. The insect flies to a different flower.
  3. Pollen from the insect’s body and legs sticks to the stigma of the new flower.
  4. The pollen grain grows a tube from the stigma down to the ovule.
  5. Part of the pollen grain moves down the tube toward the ovule.
  6. Part of the pollen grain joins with the ovule inside the ovary and makes a seed.
