The tissue between the upper and lower epidermis is called
(1) Chlorophyll
(2) Mesophyll
(3) Cambium
(4) Endodermis
Mesophyll in dicot leaves has two type of cell namely_________.
(1) Palisade parenchyma and spongy parenchyma
(2) Pith and Protoxylem
(3) Xylem and phloem
(4) Epidermis and endodermis
Vascular bundles are surrounded by a layer of thick walled ________.
1. Bundle sheath cells
2. Cuticle
3. Casparian strip
4. Waxy cell
In monocot leaf
1. Stomata is present on both surface of epidermis
2. Mesophyll is not differentiated into palisade and spongy parenchyma
3. There is no parenchyma
4. Both 1 and 2
In grasses certain adaxial epidermal cells along the vein modify themselves into large, empty, colourless cells called ________.
(1) Bark
(2) Bulliform cells
(3) Bundle sheath cells
(4) Spongy mesophyll cells
Bulliform cells help in
(1) Heat resistance
(2) Minimizing water loss
(3) Maintaining ion balance
(4) Mineral acquisition
The similar size of vascular bundle in monocot leaf is due to
1. Reticulate venation
2. Parallel venation
3. Branched venation
4. Radial venation
The tissue involved in secondary growth are
(1) Vascular cambium
(2) Cork cambium
(3) Pith
(4) Both A and B

(1) Intrafascicular cambium
(2) Interfascicular cambium
(3) Metafascicular cambium
(4) Radial cambium
When cambial ring becomes active, the cells cut off toward pith mature into
(1) Primary xylem
(2) Secondary xylem
(3) Primary phloem
(4) Secondary phloem
