2 all tissues except epidermis and vascular bundles
3 epidermis and cortex
4 all tissues internal to endodermis
Explanation:
(b) Ground tissue includes all tissues except epidermis and vascular bundles. The ground tissue comprises the bulk of the primary plant body. Parenchyma, collenchyma and sclerenchyma cells are common in the ground tissue.

In land plants, the guard cells differ from other epidermal cells in having:
1 cytoskeleton
2 mitochondria
3 endoplasmic reticulum
4 chloroplasts
Explanation:
(d) Guard cells differ from epidermal cells in having chloroplast. The cell wall of guard cells are not uniform, inner walls are thicker than the outer walls, epidermal cells are uniformly thin.

One of the primary function of the ground tissue in a plant is
1 photosynthesis.
2 to protect the plant.
3 to anchor the plant.
4 water and sugar conduction.
Explanation:
(a) All tissues except epidermis and vascular bundles constitute the ground tissue. In leaves the ground tissue consists of thin-walled chloroplast containing cells called mesophyll cells that actively involve in the process of photosynthesis.

Some vascular bundles are described as open because these
1 are surrounded by pericycle but not endodermis.
2 are capable of producing secondary xylem and phloem.
3 possess conjunctive tissue between xylem and phloem.
4 are not surrounded by pericycle.
Explanation:
(b) Open means presence of cambium during secondary growth. Vascular cambium divides to form secondary xylem towards inner side while secondary phloem towards outside.

1 Inner walls of guard cells are thick and in elastic.
2 Guard cells invariably possess chloroplasts and mitochondria.
