  • Describe plant growth, reproduction, dispersal and why bees are so important.

Mahi Tuatahi

  1. What are some organelles that only plant cells have?
  2. What are some organelles that both plant and animal cells have?

Plants, like animals, need to reproduce to survive. Without reproduction there would be no more plants.

But how do they do it?!

Reproductive Cycle

  1. Plants produce pollen
  2. This pollen can be carried away from the plant by animals, wind or rain
  3. Once on a different plant, this pollen can fertilise the flower by landing on its stigma
  4. The pollen may germinate (grow down into) the ovule of the plant
  5. This can result in the growth of seeds or fruit

The seeds from the fruit can then grow through mitosis once in the ground to form new plants!

Self and Cross-Pollinating

  • Self-Pollinating: The plant can fertilise itself
  • Cross-Pollinating: The plant needs to get pollen from another flower of the same species


  1. Glue in your flower diagram
  2. Glue in your reproductive cycle diagram
  • Anther: The top of the stamen where the pollen is stored “male” reproductive parts
  • Filament: Supports the anther
  • Stamen: The appendage containing anther and filament

  • Petal: The aesthetic part of a flower; attracts pollinators
  • Sepal: Protects the flower when not in bloom; supports the petals when in bloom

  • Stigma: Receives (captures) pollen to be used in reproduction
  • Style: A hollow tube through which pollen can grow to reach the ovary
  • Ovary: Contains the ovules (eggs; female reproductive parts)
