NEET BIOLOGY

Detailed explanation-1: -Here, phloem parenchyma acts as both packaging material as well as transfer cells. The parenchyma cells in the phloem tissue are known as phloem parenchyma and of two types such as companion cells and albuminous cells. The parenchyma cells fill the gaps between other cells therefore known as packaging cells.

Detailed explanation-2: -Parenchyma serves as packing tissue to fill the spaces between other tissues. It stores waste materials of plants such as gum, crystals etc. The intercellular air spaces of parenchyma cells allow gaseous exchange.

Detailed explanation-3: -Areolar tissue is commonly known as packaging tissue.

Detailed explanation-4: -Parenchyma a simple permanent tissue of plants is the (best) basic packing tissue.

Detailed explanation-5: -These parenchymal cells are loosely packed cells with large intercellular spaces wherein the air cavities or the air pockets are present, which provide the required buoyancy to the plant afloat. The gases (oxygen or carbon dioxide) stored in the aerenchyma can be utilized by the plant also.
