Explanation:
Exp:B (a) Annular thickening:- These are ring Like thickening present on the inner side of primary wall. (b) Spiral or helical thickening:- These are spiral or Helical thickening of secondary wall materials. (c) Scalar form thickening:- The Thickening appear as parallel transverse bands like the rungs of a ladder. (d) Simple pit:- A pit is said to be simple where the secondary wall does not arch over the pit chamber and so the rim of the pit aperture contains no border.

Dendrochronology is the study of
1 height of a tree
2 diameter of a tree
3 age of the tree by counting the number of annual rings in the main stem
4 None of the above
Explanation:
Exp:C Study of age of trees by counting the number of annual rings in the main stem is Dendrochronology. - Each year, the tree forms new cells, arranged in concentric circles called annual rings or annual growth rings.

3 (A), (C), (D) and (E) Only
4 (A), (B) and (D) Only
5 It has lower density Choose the correct answer from the options given below:
Explanation:
Exp:C Spring wood is also called early wood, it is lighter in color and has a lower density. The vessels are produced with the wider lumens to transport more water to meet the requirement by increased transpiring surface in spring season. - The spring and autumn wood appears as alternate concentric rings of light and dark color forming annual rings.

In a ring girdled plant :
1 The root dies first
2 The shoot and root die together
3 Neither root nor shoot will die
4 The shoot dies first
Explanation:
Exp:A In the ring girdled plant, the root dies first. A ring of bark is cut from the stem. It also removes phloem. The phenomenon of ring girdling occurs when the cork cambium and phloem are stripped away, as result nutrition and water movement in the plant stop. The root dies because it is unable to obtain enough sugar to survive.

4 Both (b) and (c)
Explanation:
Exp:B The cambium present between xylem and phloem in vascular bundle is called interafasicular cambium. The intrafasicular cambium joint to interfasicular cambium together called/Inter stellar cambium. - The winter season activity of cambium loss and produces small sized vessels which are dark colored and loss amount it is called winter wood or autumn wood or late wood. In spring season the activity of cambium are more, it produces large sized narrow vessels large in amount called spring wood or early wood.
