Apical meristems - These are situated at the growing tip of stems and roots. Lateral meristems - These are found beneath the bark and in vascular bundles of dicot roots and stems. Intercalary meristems - These are located at the base of leaves and internodes.

This is the correct option. The cell walls of sclerenchyma are greatly thickened with lignin. Lignin is a complex polymer which acts as a cement and hardens the cell walls.

Yes, it is correct. Meristematic tissues are found in those regions which need to grow continuously. Primary meristems appear early in the life of a plant and are responsible for the formation of primary plant body. Primary growth involves development of new parts of a plant and growth in the length of a particular part. Both apical and intercallary are primary meristems.

The plant tissues become woody by the process of lignification.

Phloem fibres have non-living cells.

Simple permanent tissues are usually loosely packed.

Meristematic tissues exhibit cell division.

Cambium is a lateral meristematic tissue.

Sclerenchymatous tissue is present in the husk of coconut, which comprises of dead cells with thickened cell walls due to deposition of lignin and hemicellulose. This makes husk of coconut hard and stiff. That is why it is difficult to remove.

1 – (d), 2 – (c), 3 – (b), 4 – (a)

Tracheids - Transport minerals Companion cells - Dense cytoplasm Sieve tubes - Transport metabolic products Xylem - Complex permanent tissue

Aerenchyma is present in aquatic plants to provide buoyancy.

Cells of vessels do not have end walls. 

Statement (c) is incorrect. It reduces, not increases, the rate of transpiration by developing cuticle.

This is the correct option. The parenchyma which contains chloroplasts is called chlorenchyma. The parenchyma which contains large air cavities or spaces is called aerenchyma. The parenchyma which stores water or food or waste products is called storage tissue.

This is the correct option as this is not a property of the cells of the parenchyma. The cells of the parenchyma are not thick-walled. They are thin-walled.
