Parts of Plant

Plant

Plant are mainly multicellular organism, predominantly photosynthetic eukaryotes of the kingdom Plantae. Plant are divided into 2 system i.e root system and shoot system.

Root system - The underground part of the flowering plant.

Shoot system - The portion above the ground

1. Root

• Underground non-green part (due to absence of chlorophyll)
• They anchor the plants in the soil
• Absorb water and nutrients from the soil
• It is also used to store food
• Root arise from radicle

2. Stem

• Support the upper part of plant
• The Bark of trees are brown in colour & younger stems are green in color
• It forms the base of shoot system
• Stems arise from plumule
• Helps in upward movement of water

 

3. Leaf

• The most important part of a plant
• They contain chlorophyll that helps the plants to prepare their food
• Photosynthesis usually occurs in leaves
• Photosynthesis - The green substance chlorophyll, captures sunlight & uses it to convert water and carbon- dioxide in to plant food any oxygen.

 

4. Flowers

• Flowers are the most beautiful and colorful part of a plant
• They are the reproductive part of a plant
• Flower are also a source of food for other living organisms
• They are a rich source of nectar

5. Fruit

• Fruits are the main features of a flowering plant
  
• Fruit can be fleshy like an apple mango or hard like a nut
• Fruit usually surround seeds. They protect the seeds & attract animals to eat them.
• It is a matured ovary that develops after fertilisation
• Some fruits are developed without fertilization & are known as parthenocarpic fruits 
• Example:- Banana, Coconut

6. Seeds

• Contain plant material that can develop into another plant
• This plant material is called an embryo.
• Seeds are covered with a protective seed coat & have 1 or 2 cotyledons
