NEET BIOLOGY

Detailed explanation-1: -Lenticel: A lenticel is a porous tissue made up of cells with large intercellular gaps that can be found in the periderm of woody stems and roots of dicotyledonous flowering plants. Lenticels appear as elevated scars on the bark’s surface with oval or circular depressions.

Detailed explanation-2: -A lenticel is a porous tissue made up of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledons flowering plants. The tiny pores which are elliptical in shape are lenticels.

Detailed explanation-3: -It acts as a pore, allowing direct gas exchange between internal tissues and the atmosphere via the bark, which is otherwise impervious to gases. Lenticels enhance oxygen, carbon dioxide, and water vapor exchange in plant bodies that induce secondary growth.

Detailed explanation-4: -Hint: Lenticels are the large sized, aerating pores present in the cork tissue known as lenticels. They are found in old dicotyledonous stems or dicot stems. They are formed in the place of stomata. Lenticels help in exchange of gases between the tissues.

Detailed explanation-5: -Lenticels are one of many raised pores in the stem of a woody plant that allows gas exchange between the atmosphere and the internal tissues.
