Life cycle of plants- Part 1

Life cycle of a plant

It is braodly classified in 3 stages:

• Seed
• Seeding
• Adult plant

But it has other stages in between as described below:

• The seed first absorbs water
• Then it gives rise to the root
• Then it gives rise to the shoot system
• Finally it forms the small plant to photosynthesise

Photosynthesis: An adult green plant needs water, air and sunlight/warmth to produce it's own food. This process is called photosynthesis (photo- meaning light, synthesis- meaning making). In photosynthesis plants takes in carbondioxide and gives out oxygen.

Respiration: It is the opposite of photosynthesis. In respiration plants takes in oxygen and gives out carbondioxide. This happens in most green plants during the night time, hence no sunlight is needed.
