Anatomy of Flowering Plants

The sclerenchyma of the hypodermis in the Pinus needle helps in:
1 increasing the absorptive surface of the cell
2 checking transpiration
3 mechanical support
4 photosynthesis
Explanation:
Exp:C Sclerenchyma provides mechanical support in the pinus needle as it has thick walls. Sclerenchyma may be fibres or sclereoid. The epidermis is covered on the outside by a thick cuticle, which helps in checking transpiration. The parenchymatous mesophyll consists of thin walled cell which contain numerous chloroplasts and thus photosynthetic in function.

The epidermal hairs present on the stem of the plant is called
1 trichomes
2 root hairs
3 stomata
4 guard cells
Explanation:
Exp:A The epidermal hairs present on the stem of the plant is called trichomes. The roots hairs are unicellular, elongated of the epidermal cells and helps to absorb water and minerals from the soil on the stem.

Vascular tissues in flowering plants develop from
1 phellogen
2 plerome
3 periblem
4 dermatogens
Explanation:
Exp:B Plerome:- Lies in the centre, it give rise stele including pericycle pith or medulla pith rays or medullary rays and vascular bundle. The part of the plerome from which vascular tissues are fashioned is known as procambium.

Piliferous layer in the root is
1 epidermis
2 pericycle
3 cortex
4 endoderics
Explanation:
Exp:A Epidermis:- Piliferous layer is the part of the root epidermis, that bears root hairs. It extends over a region about \(410 \mathrm{~nm}\) behind the root tip. Beyond this the piliferous layer is sloughed to reveal the hypodermis.
