The correct order in the lifecycle of a plant is:

1. Seed-seedling- mature plant-flowers-fruit-seed.
2. Seedling-seed-mature plant-flowers-fruit-seed.
3. Seed-flower-fruit-seed-seedling-mature plant-seed.
4. Seedling-seed-flower-fruit-mature plant-seed.

An example of an organ of a plant is:

1. Chloroplast
2. Vacuole
3. Leaf
4. Cell wall

Name a class of animals that can help plants reproduce.
