Vascular tissues in flowering plants develop from

Passage cells are thin-walled cells found in:
1. endodermis of roots facilitating rapid transport of water from cortex to pericycle
2. phloem elements that serve as entry points for substances for transport to other plant
parts
3. testa of seeds to enable emergence of growing embryonic axis during seed
germination
4. central region of style through which the pollen tube grows towards the ovary
For a critical study of secondary growth in plants, which one of the following pairs is
suitable:
1. Sugarcane and sunflower
2. Teak and pine
3. Deodar and fern
4. Wheat and maiden hair fern
If the stoma remains surrounded by a limited number of cells which cannot be
distinguished from other epidermal cells, then this type of stomata is known as.

3. anisocytic type
4. anomocytic type
In the given diagram of section of root of maize, different parts have been indicated by
alphabets. Choose the answer in which these alphabets have been correctly matched
with the parts which they indicate.
1. A = Phloem, B = Xylem, C = Cortex, D = Endodermis, E = Pith, F = Root hair, G =
Epidermis
2. A = Pith, B = Root hair, C = Epiblema, D = Cortex, E = Endodermis, F = Phloem, G
= Xylem
3. A = Root hair, B = Epiblema, C = Cortex, D = Endodermis, E = Pith, F = Xylem, G
= Phloem
4. A = Epiblema, B = Root hair, C = Vascular bundle, D = Cortex, E = Phloem, F =
Xylem, G = Pith
