PROJECT ON FLOWERING PLANTS NAME : SEJAL SINGH CLASS : VI-C ROLL NO. 22 SUB : SCIENCE

TYPES OF PLANTS:

TYPES OF PLANTS Herbs – These are the small plants with soft, green stems, which may or may not have branches. Most herbs live for just one season or two seasons. They are known as annuals and biennials. E.g. rice, mustard and sunflower are annuals and radish, beet and carrot are biennials.

TYPES OF PLANTS:

TYPES OF PLANTS Shrubs – The stem is hard and woody, unlike the stem of herbs. These plants are often grown as hedge plants. China rose, henna (mehandi) and rose are some shrubs. Trees – Trees are tall, perennial plants with a thick, hard, woody stem called trunk. Mango, kikar are some trees.

PARTS OF A PLANT:

PARTS OF A PLANT A plant has two parts. The part above the ground, consisting of the stem, leaves, flowers and fruits, is called the shoot. The part below the ground is called the root. The roots of land plants grow underground. Though they serve the same purpose, they are of two major types, as the following activity will show you.

THE STEM:

THE STEM Stem Tendril

FUNCTIONS OF THE ROOT:

FUNCTIONS OF THE ROOT Fixing the plant to the soil is a major function of the root. The root absorbs water and minerals from the soil. The plant uses these to manufacture food and carry out life functions. So, another major function of the root is to gather raw material for the plant. By holding on to the soil, they bind it together and stop it from being blown away by the wind or washed away by the rain. This is why planting trees helps to protect the soil. SOME ROOTS STORE FOOD :- The roots of some plants are modified, or look different from ordinary roots. These modifications occur to help the roots serve additional functions.

THE STEM:

THE STEM Notice the points from where the leaves grow. These are called the nodes. And the portion of the stem between any two nodes is called an internode. STEMS WHICH STORE FOOD :- Just like roots, some stems are also modified to perform special functions.

PARTS OF LEAF:

PARTS OF LEAF Venation :- When the veins run parallel to each other, as in grass, bamboo, banana, canna, palms and sugar cane. Simple and compound leaves :- The leaf blade of some leaves is divided into leaflets. Such leaves are known as compund leaves.

PARTS OF A FLOWER:

PARTS OF A FLOWER The stalk of a flower is called the pedicel. The stalklike growths with swollen, powdery heads are the stamens. The flasklike structure at the centre of the flower attached to the stalk with a swollen tip is called the carpel. The flower has four whorls.
