2. Sclerenchyma
3. Xylem
4. Meristem

Fibres are likely to be absent in
1. Secondary phloem
2. Secondary Xylem
3. Primary phloem
4. Leaves

When we peel the skin of a potato tuber, we remove
1. Periderm
2. Epidermis
3. Cuticle

A vessel less piece of stem possessing prominent sieve tubes would belong to
1. Pines
2. Eucalyptus
3. Grass
4. Trachodendron

Consider the given two statements:

1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is True but II is False
4. Both I and II are False

In the given diagram of the root apical meristem, what would be true for the structure labeled as number 1?

1. The cells in the region continually divide to produce cells of region 5
2. The cells in this region divide at much faster rate than the cells of region 2
3. The cells of this region are able to repopulate the borderline meristematic regions when they are injured
4. The cells of this region include the initials of region 3

Match the parts labeled as A, B and C in the diagram of stem apex with their derivatives in the plant body:

II. They can continue to develop thick flexible walls while the organ is still elongating.

1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is true but II is false
4. Both I and II are false
