What four things are needed for photosynthesis?

What part of the flower develops into the seed after fertilisation?
The ovule
Why do plants disperse their seeds?

Suggest four things a plant needs to grow healthily.
Sunlight, water , minerals/ nutrients and carbon dioxide.
Suggest a reason why a plant may have bright yellow petals.
To attract insects for pollination.
Describe why hooks help plants disperce it’s seeds.
