• D. Has a green pigment

Answer 1

The correct option is C

Absorption of water and minerals from the soil

The correct option is C.

The explanation for the correct options:

1. A flattened structure of a higher plant, generally green and blade-like is known as a leaf.
2. The absorption of water and minerals is not a function of the leaf.
3. The absorption of water and minerals from the soil is the function of the roots present in the plants.
4. The root is the part of a vascular plant, which is usually underground.

The explanation for the incorrect options:

Option A:

1. The process in which water is lost in the form of water vapor via the stomata present in the leaves of plants is transpiration.

Option B

1. The process by which plants utilize water, sunlight, and carbon dioxide to produce energy in the form of sugar and oxygen as a by-product is photosynthesis.
2. The leaves are adapted and designed in a manner to permit the process of photosynthesis to take place.

Option D:

1. The leaf comprises a green pigment known as chlorophyll, which helps in the process of photosynthesis.
2. The main function of chlorophyll is to captivate the light coming from the Sun, which is further used to produce food via the process of photosynthesis.

Final answer: Absorption of water and minerals from the soil is not a characteristic of the leaf.
