Plant Reproduction

Mahi Tuatahi

Write the date in your book and then answer the following two questions.

1. What are some organelles that only plant cells have?
2. What is an organelle that plant root cells have? What does it do?

Ngā Whāinga Ako

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

Write this learning outcome in your book.

Reproductive Cycle

You have been given a timeline of plat reproduction, but it is out of order.

1. Put a heading “Plant Reproduction” in your book
2. Cut up the timeline
3. Work with the person next to you to put them into order
4. Be ready to check and then glue them into your book

Whakatika

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
6. These seeds can be carried away from the plan by animals, wind, or rain

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

Task

Yesterday during the dissection you drew a diagram of a flower in your book and labelled the parts.

If you were away or your drawing was incomplete, collect and glue in a diagram.

Stamen: The appendage containing anther and filament

Anther: The top of the stamen where the pollen is stored “male” reproductive parts

Filament: Supports the anther

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). It becomes fruit.

Ovules: Become seeds to grow new plants.
