Plants give us food, medicines and clothes, and they give us the oxygen we need to live. Plants have different life processes: nutrition, interaction and reproduction. We can classify plants into: Herbaceous, bushes and trees.Plants breathe and make their own food. To breathe, they absorb oxygen and release carbon dioxide. To make their own food they absorb sunlight, water and minerals and carbon dioxide. And they release oxygen to the atmosphere.

1. Most flowers have male and female reproductive organs.2. The pistil or carpel is female reproductive organ. IT PRODUCES OVULES.3. The stamens are the male reproductive organs. THEY PRODUCE POLLEN.4. Pollination takes place when pollen travels from one flower to another. It can be animal pollination or wind pollination.5. Fertilization takes place with the union of a grain of pollen and an ovule.6. The seed grows and grows in the carpel.7. The seed becomes a small fruit.8. The fruit gets bigger and bigger. The petals fall down.

9. The fruit changes colour. Many seeds grow inside it. The seeds fall to the ground because: the fruit has ripened or because animals that eat fruits have excreted them.10. Germination takes place when a new plant grows from each seed.11. The small plants turn into big ones. New parts grow in the plant such as trunks, branches, flowers, etc.12. Most flowers have male and female parts

Animal pollination is carried out by birds and insects. Colourful petals attract animals to a flower to drink nectar. Pollen from the stamens stick to the animal's body.

Wind pollination is used by plants which do not have colourful petals to attract animals.

1. The roots fix the plant to the ground.2. Water and minerals rise up through some vessels called xylem and then reach the leaves.3. The leaves mix water, minerals, sunlight and carbon dioxide and produce sap or glucose.4. Chloroplast in the leaves help to make sap or glucose.5. The leaves have holes called stomata that absorb carbon dioxide and release oxygen to the atmosphere.6. Sap or glucose circulates from the leaves to the rest of the plant.

7. Photosynthesis is the process in which plants use water, minerals, sunlight and carbon dioxide. This also means that plants release oxygen to the atmosphere.
