1. Roots: Anchor the plant, absorb water and nutrients from the soil.

2. Stems: Support the plant, transport water and nutrients.

3. Leaves: Carry out photosynthesis (making food from sunlight).

4. Flowers: Responsible for reproduction (producing seeds).

While flowers are important for reproduction, they are not found on all plants. There are many plants that reproduce through other methods, such as spores.
