Botany and Plant Science

The parrenchyma tissue stores waste products of plants like, tanin, gum, crystals and resins.

Prosenchyma is a type of parenchyma, where cells are elongated with tapering ends.

Armed parenchyma is the parenchyma, which is found in the epidermis of leaves, in some gymnosperms. The cells have many spiny projections. It is defensive in function.

Conjunctive parenchyma, is the parenchyma, which occurs in the root system. It is specially meant for storage of water.

Medullary parenchyma, is the parenchyma, which is found radially arranged in between the vascular bundles in the stem. It is meant for storage of reserve food.

Vascular parenchyma, is the parenchyma, which is found associated with the vascular tissues, xylem and phloem. Accordingly, it is distinguished into, xylem parenchyma and phloem parenchyma.

Arenchyma, is the parenchyma, in which the cells enclose large intercellular spaces, that are filled with air. Aerenchyma helps in buoyancy and respiration. It is characteristically found in aquatic floating plants.

Chlorenchyma, is the parenchyma, in which the cells contain large number of chloroplasts. Chlorenchyma takes part in photosynthesis. It occurs in the leaves, and other green parts of the plant body.

Arenchyma, is the parenchyma, in which the cells enclose large intercellular spaces, that are filled with air. Aerenchyma helps in bouyancy and respiration. It is characteristically found in aquatic floating plants.

Juvenile stage of funaria is called protonema.

Leaves are the primary site of photosynthesis, where solar energy is converted into chemical energy stored in glucose and starch.

The epidermis is the outermost layer of cells in plant roots, stems, and leaves. It provides protection and regulates gas exchange.

The endodermis is the innermost layer of the cortex in plant roots. It surrounds the vascular cylinder and regulates the flow of water into the xylem.

The cortex is the ground tissue in a plant root or stem that lies between the epidermis and the vascular bundle.

Xylem is the vascular tissue that transports water and minerals from the roots to the upper parts of the plant.
