Which of the following is correct about dorsiventral leaf?
1 The veins vary in thickness in the reticulate venation.
2 Palisade parenchyma is located towards the upper epidermis
3 Reticulate venation is seen
4 All are correct
Explanation:
The size of the vascular bundles are dependent on the size of the veins. The veins vary in thickness in the reticulate venation of the dicot leaves. Palisade parenchyma is located towards the upper epidermis.

Vascular bundles in the leaves of dicots are surrounded by
1 Thin walled bundle sheath cells
2 Thick walled bundle sheath cells
3 Both 1 and 3
4 Sclerenchymatous bundle sheath cells
Explanation:
The vascular bundles are surrounded by a layer of thick-walled bundle sheath cells. These cells contain chloroplasts and are the site of photosynthesis.

Statement A : The vascular bundles are surrounded by a layer of thick walled bundle sheath cells, in dicotyledonous leaf. Statement B : The mesophyll is not differentiated into palisade and spongy parenchyma in isobilateral leaf.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Both the statements are correct. The vascular bundles are surrounded by a layer of thick walled bundle sheath cells in dorsiventral leaf (leaf of dicotyledonous plant). In an isobilateral leaf (leaf of monocotyledonous plant), the mesophyll is not differentiated into palisade and spongy parenchyma.

Which would do maximum harm to a tree?
1 Loss of fruits
2 Loss of half of its flowers
3 Loss of all of its leaves
4 Loss of all its bark
Explanation:
The bark is an outermost layer of the stem of woody plants. All the tissues outside the vascular cambium are called as bark. It protects the tree from external damage, bacterial infection and loss of water. If all the bark of the tree is removed then water loss will dry out the tree will also become vulnerable to infections.
