Plant Anatomy Plant Tissues MCQs for NEET — Botany Questions with Answers

The correct matching of tissue types with their functions is:

1. Parenchyma (c) support, protection, storage
2. Lateral meristem (d) Increase in diameter of trunk
3. Apical meristem (a) Increase in length of plants
4. Intercalary meristem (b) Increase in nodal region. Parenchyma cells are involved in storage and support, lateral meristem is responsible for the secondary growth (increase in diameter), apical meristem is involved in primary growth (increase in length), and intercalary meristem helps in the elongation of internodes.

Parenchyma is always present in the ground tissue of the roots and stems of all plants. It is the most common and versatile ground tissue and plays a role in storage, photosynthesis, and tissue repair.

Bulliform cells are large, bubble-shaped epidermal cells that occur in groups on the upper surface of the leaves of many monocots, such as grasses. These cells help in the folding and unfolding of leaves by changing their turgor pressure.

The vascular cambium and cork cambium are examples of lateral meristems. Lateral meristems are responsible for the secondary growth in plants, which increases the thickness of stems and roots. Unlike apical meristems which are found at the tips of roots and shoots, lateral meristems contribute to the growth in girth.

When a plant tissue is stained with safranin and fast green, the phloem typically appears red. Safranin stains lignified, suberized, or cutinized cell walls red, while fast green stains cellulose cell walls green. Since phloem cells are not lignified, they take up the safranin stain and appear red.

Cork cambium, also known as phellogen, produces cork cells on its outer surface. These cork cells become impermeable to water due to the accumulation of suberin, a waxy substance that reduces water loss and protects the plant from pathogens.

they are seen in dicot trees and gymnosperm trees
