Solution
The correct option is A A- 4, B- 3, C- 2, D- 1
Parenchyma cells in the mesophyll of leaves are a specialised parenchyma cells called as chlorenchyma cells (parenchyma cells with chloroplasts). In leaves, they form the mesophyll and are responsible for photosynthesis and the exchange of gases.
Aerenchyma is the spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root. The channels of air-filled cavities provide a low-resistance internal pathway for the exchange of gases such as oxygen and ethylene between the plant above the water and the submerged tissues. Aerenchyma is also widespread in aquatic and wetland plants which must grow in hypoxic soils.
An idioblast is an isolated plant cell that differs from neighbouring tissues. They have various functions such as storage of reserves, excretory materials, pigments, and minerals. They could contain oil, latex, gum, resin, tannin or pigments, etc.
Prosenchyma is a type of plant tissue consisting of elongated cells with tapering ends, occurring in supporting and conducting tissue.
Thus, the correct answer is option A.
