Section 1
Flowers House Plant Reproductive Structures
Flowers contain male stamens that produce pollen and female pistils with ovaries housing eggs. After fertilization, the ovary develops into fruit containing seeds for plant reproduction.
In this Grade 7 Life Science lesson from Chapter 11, students learn how angiosperms reproduce using flowers and fruit, tracing the full life cycle from pollen and fertilization through seed and fruit development. The lesson covers key structures such as the anther, pistil, ovary, and pollen tube, and explains how the ovary wall develops into fruit after fertilization. Students also explore how flowering plants can reproduce asexually through runners, and examine the relationship between animals, humans, and flowering plants.
Section 1
Flowers House Plant Reproductive Structures
Flowers contain male stamens that produce pollen and female pistils with ovaries housing eggs. After fertilization, the ovary develops into fruit containing seeds for plant reproduction.
Section 2
Animals Transport Pollen Between Flowers
Bees, birds, and other animals visit flowers for nectar, collecting pollen on their bodies. They carry this pollen to other flowers, facilitating fertilization with greater precision than wind pollination.
Section 3
Fruits Protect and Disperse Seeds
Fruits develop from fertilized ovaries, surrounding seeds with protective fleshy or dry coverings. Animals eat fruits and deposit seeds elsewhere or carry hooked seeds on fur, dispersing plants to new locations.
Section 4
Plants Provide Essential Resources for Life
Plants produce oxygen through photosynthesis, create food for animals, build soil through root action, and supply materials for human products including medicine, clothing, paper, and building materials.
