The part of the leaf between the upper epidermis and the lower epidermis is called
1 mid rib
2 hypodermis
3 mesophyll
4 palisade
Explanation:
Exp:C The leaf tissue that lies between the upper and lower mesophyll and between the veins is usually composed of thin walled parenchyma, called the mesophyll, the tissue that forms the major part of the inner leaf, usually the cells of the mesophyll are two types are - (i) Palisade parenchyma or palisade tissue (ii) Spongy parenchyma or spongy tissue

In which of the following manner distribution of stomata occur in dorsiventral leaf?
1 More in palisade tissue and less in spongy parenchyma
2 Equal in both palisade and spongy parenchyma
3 More in spongy parenchyma and less in palisade tissue
4 Absent in all of these
Explanation:
Exp:C Palisade tissue may consist of one or more layers these cells are arranged near the upper surface of the leaf. Where they receive sunlight and attracted to perform of photosynthesis sometimes the leaves hang vertically so that both leaf surface are equally illuminated the palisade parenchyma of such leaves depends on the intensity of light. - The lower portion of the mesophyll in the leaf is known as spongy parenchyma or spongy tissue. The spongy tissue is usually composed of loose irregular in walled cells having big inter cellular spaces (airspaces) among them.

The cells which help in rolling and unrolling of leaf lamina in grasses are:
1 complementary cells
2 motor cells
3 passage cells
4 companion cells
Explanation:
Exp:B In grasses certain adaxial epidermal cells along the veins modify themselves in to large empty colorless cells these are called bulliform cells. - When the bulliform cells in the leaves have absorbed water and are turgid the leaf surface is exposed when they are flaccid due to water stress. The leaves curl in wards to minimize water loss.

Palisade parenchyma is absent in leaves of -
1 Gram
2 Sorghum
3 Mustard
4 Soybean
Explanation:
Exp:B Monocot mesophyll is not differentiated into palisade and spongy layers. Hence, sorghum (monocot) does not have palisade parenchyma. palisade cells occur in dicotyledonous plants and also in the net-veined monocots. They are present in dicots such as gram and soybean.
