	D.Lesser number of xylary elements.

Ans: Lesser number of xylary elements.
Explanation:
Spring season produces a wood which has large number of xylary elements having vessels with wider cavities.

	A.vascular rays
	B.tracheary elements
	C.ray parenchyma
	D.phloem parenchyma

Ans: tracheary elements

	A.radicle
	B.cotyledon
	C.mesocarp
	D.plumule

Ans: plumule
Explanation:
Stem develops from plumule.

Q9.	Stem grows in girth due to
	A.outer cortical
	B.epidermis
	C.vascular cambium
	D.phellogen

Ans: vascular cambium

	D.xylem vessels

Ans: cambium

Q12.	Pith is very well developed in
	A.monocot root and monocot srem
	B.monocot root and dicot root

Q13.	Which of the following helps in the curling of the leaf surface?
	A.Bulliform cells
	B.Xylem tissue
	C.Palisade parenchyma
	D.Bundle sheath cells

Ans: Bulliform cells
Explanation:
In grasses, adaxial epidermal cells along the veins modify themselves into large, empty, colorless cells. These are called bulliform cells.
When there is water stress leaves curl themselves inward to minimise water loss.
When the cells have absorbed water and are turgid, the leaf surface is exposed.
