Exp:D The cambium present between the xylem and phloem of the vascular bundle is called vascular fascicular cambium. The vascular cambium is the main growth tissue in the stems and roots of many plants, specifically in dicots such buttercups and oak trees, gymnosperms such as pine trees, as well as in certain other vascular plants.

Opening and closing of stomata is due to the : -
1 Hormonal change in guard cells
2 Change in Turgor pressure of guard cells
3 Gaseous exchange
4 Respiration
Explanation:
Exp:B Opening and closing of stomata take place due to turgor pressure that changes in guard cells. As the solute particles enter the guard cells from the epidermal and mesophyll cells, both the osmotic potential and the water potential of the guard cells get lowered and potassium ions \(\left(\mathrm{K}^{+}\right)\)enter the guard cells. This creates a water potential gradient which makes the water moves towards the guard cell, it creates a hydrostatic pressure in the guard cell and thus becomes turgid and swell in size which causes stomata opening. With a decline in guard cells solutes, water moves out of the guard cells, making them flaccid, this occurs because potassium ions move back out of the guard cell, so stomata closed.

Peroxisomes are found in
1 bundle sheath
2 endosperm
3 mesophyll cells
4 vascular bundles
Explanation:
Exp:C Peroxisomes found in all eukaryotic cells. It is small organelles found in the photosynthetic mesophyll cells in plant. They play vital role in the process of photorespiration. These are also involved in metabolism, development, and responses to stresses. Peroxisomes are the sole site of fatty acid \(\beta\)-oxidation in plant cells.

Idioblasts are specialized, non-green large sized
1 Sclerenchyma cells
2 Parenchyma cells
3 Colenchyma cells
4 Aerenchyma cells
Explanation:
Exp:B Idioblasts are specialized, non-green large sized parenchyma cells. It is a type of simple permanent tissue that makes a major part of ground tissues in plants, where other tissues such as vascular tissues are embedded.

Non-cellular layer that connects inner surface of the epithelial tissue to the connective tissue is
1 Endodermis
2 Cuticle
3 Connective tissue
4 Basement membrane
Explanation:
Exp:D Epithelial tissue is separated from the underlying tissue by a non-cellular layer called the basement membrane. The basement membrane is a thin, non-cellular tissue with blood vessels present underneath on which the epithelium sits.
Exp:D The cambium present between the xylem and phloem of the vascular bundle is called vascular fascicular cambium.
