Important Questions on Transport in Plants
Mark A, B, C, and D in the given figure.
In which type stomata are exclusively present on the upper surface of the leaf
The figure shows diagrams of T.S of two plant organs, X and Y, containing vascular tissue. Which of the following rows correctly identifies the tissues?
A. Root hair zone
B. Zone of meristems
C. Root cap zone
D. Zone of maturation
E. Zone of elongation
Consider the following statements:
1. Epidermis and cortex of monocot root are similar to those of dicot root.
2. Hypodermis of dicot stem consists of sclerenchymatous cells.
3. The cells of bundle sheath in maize leaf serve as temporary storage cells.
4. The dicot leaf is hypostomatic.
Which of these statements are correct?
Stomata are equally distributed on both the surfaces.
Certain adaxial epidermal cells are modified into bulliform cells in grasses.
The vascular bundles are radial.
Phloem is adaxially placed.
Which of the above statements are correct?
| I | II | ||
|---|---|---|---|
| (a) | Bulliform cells | (i) | Regulate opening and cells closing of stomata |
| (b) | Guard cells | (ii) | Aerating pores in the bark of plant |
| (c) | Lenticels | (iii) | Rolling in and out of leaves |
| (d) | Subsidiary cells | (iv) | Accessory cells |
Assertion All the endodermal cells of the root do not contain casparian thickenings on their radial and transverse walls.
Reason : Passage cells are found in the root endodermis.
