Plant Life Processes

Plants

Plants make food during the process of Photosynthesis. Plants feed themselves by using the light to convert carbon dioxide and water into food. Catching light is therefore a very important part of the plants growing process.

Plants are built to go through a life cycle. There are four main parts to a plant that complete the four life processes:

- Flower - the flower is necessary for the Reproduction. The flowers have color and smell to help attract insects. They make pollen (male sex cells) which join to the eggs (female sex cells). The pollen is carried by flying insects as they travel from flower to flower despositing of the pollen collected on them. Part of the flower then dies and what is left becomes the new fruit which contains the seeds. Seeds are scattered by the wind, by different animals and be being flicked out of their pods. Scattered seeds often cover a wide area. If a seed falls slowly it has a better chance of being carried further by the wind.
- Leaves - the leaves help plants to grow. They are necessary for Nutrition (feeding). The green chlorophyll in the leaves absorbs the sunlight to change carbon dioxide gas and water into food. This part of the life process is called photosynthesis.
- Stem - the stem is necessary to Hold and Move the plant up towards the sunlight. The stem supports the plant and carries water and minerals from the roots to the rest of the plant.
- Roots - the roots are necessary to help plants to grow. Roots are needed for Anchoring the plant. The roots anchor the plant in the ground so it doesn’t blow away. The roots have root hairs (smaller roots) to spread out through the soil to soak up and absorb water and minerals from the soil. The roots are therefore needed for nutrition (feeding).
With the right conditions of water, light, oxygen (air), minerals and temperature a plant can grow and produce food.

Chlorophyll photosynthesis produces oxygen present in the Earth's atmosphere. Photosynthesis is a chemical reaction that happens in algae and plants. Photosynthesis is of great importance for our planet Earth and all its inhabitants because of its production of sugars, oxygen and foods.

Plants make food during the process of photosynthesis and all animals depend on plants for their food.

Germination Process

Germination is the when the baby plant (seed) starts to grow. The seed grows and sprouts its main root from the nutrients it is collecting in the soil. The main root gets bigger and side roots appear as well as the leaves.
