Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants

Answer- (d) Wheat

Fibrous roots are a type of root system where roots are thin and branch out extensively. Wheat has a fibrous root system, but Radish, Carrot, and Tapioca all have a taproot system, which is a large, central root. 

Answer: (c) To transport water and nutrients to the different parts of the plant

The main function of the stem is to transport water and nutrients from the roots to other parts of the plant, like the leaves, flowers, and fruits. 

Answer- (d) Carrot

A taproot system has a primary, thick central root that grows deep into the soil. Carrots are an example of plants with a taproot system. Grass, wheat, and maize have fibrous root systems, which consist of many small, thin roots.

Answer- (c) Stamen

The stamen is the male reproductive part of a flower. It consists of the anther and the filament. The anther produces pollen grains, which are necessary for fertilization. The pistil, stigma, and sepals are female or non-reproductive parts.

Answer- (d) Ovary

The ovary is the female reproductive part of the flower. It is located at the base of the pistil and contains ovules, which develop into seeds after fertilization. Petals, sepals, and stamen are other parts of the flower that either protect the reproductive organs or are involved in reproduction.

Answer- (b) Leaves

Leaves are responsible for making food for the plant through the process of photosynthesis. They use sunlight, water, and carbon dioxide to produce glucose (food) and oxygen. Roots absorb water and nutrients, but do not make food.

Answer- (d) Roots

Roots hold the soil together and prevent it from being washed away by rain or wind. They anchor the plant to the ground and absorb water and nutrients. This helps reduce soil erosion.

Answer – (c) Transpiration

Transpiration is the process by which plants lose water in the form of water vapor through small openings in their leaves called stomata. It helps in cooling the plant and maintaining water and nutrient flow.

Answer – (a) Photosynthesis

Photosynthesis is the process where plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process occurs in the chloroplasts of the leaves and is essential for the plant's growth and energy production.

Answer: Stems support the plant, transport water and nutrients, and in some plants, perform photosynthesis or store food.

Answer- The bunch of thin fibre-like roots; arising from the base of the stem is called fibrous root.

Answer- When as single main root comes out of the base of the stem, it is called tap root.

Answer: Functions of roots are as follows:

• Roots hold the plant firmly in the soil.
• Roots absorb water and minerals from the soil.

Answer- The basic parts of a flower are –Sepals, petals, stamens and pistils.

Answer- Making food is the main function of leaves.

Answer: Loss of water vapour in plants is called transpiration.
