Test: Plants - 1 - Class 4 MCQ

Plants have roots, stems, leaves, flowers, and fruits. These parts perform different functions in the plant's overall functioning.

The primary function of roots is to transport water and minerals from the soil to the rest of the plant.

Carrots have a taproot system, which consists of a main long and thick root that grows vertically downwards.

Root hairs are responsible for absorbing water and minerals from the soil.

The stem provides structural support to the plant and helps in the transportation of water, minerals, and food.

Large trees like neem and mango have woody stems, which are strong, thick, and durable.

The primary function of leaves is photosynthesis, where they convert sunlight, water, and carbon dioxide into sugar and oxygen.

Photosynthesis is the key process that occurs in leaves, enabling the production of food for the plant.

Stomata are small openings present on the leaf's surface, allowing for the exchange of gases, such as oxygen and carbon dioxide.

Flowers serve the purpose of reproduction in plants, as they contain the reproductive organs necessary for seed production.
