Question

Answer

Hey, Prosenchyma is a type of (c) Parenchyma. Prosenchyma is a type of parenchyma where cells are elongated with tapering ends. In some cases the cells are long and taper at either ends (as in pericycle of some plants). This is called a prosenchyma This tissue has manifold functions (i) It performs physiological func­tions like photosynthesis, secre­tion, assimilation and storages. (ii) Aerenchyma provides buoyancy to hydrophytes and also helps in gaseous exchange. (iii) It helps in healing of wound and regeneration of organs. (iv) Prosenchyma provides strength and helps in conduction. (v) It helps in formation of adventi­tious roots and buds. HOPE IT HELPS YOU.

Answer

Prosenchyma is a type of parenchyma whose cells are long and taper at either ends (as in pericycle of some plants).

Answer

Answer:
Prosenchyma is a type of plant tissue found in higher plants. It is characterized by its elongated and tapering shape, with pointed ends. Prosenchyma cells have thick cell walls, which provide mechanical strength and support to the plant.
Here are some key points about prosenchyma:
- Location: Prosenchyma is present in various parts of the plant, such as stems, roots, and leaves.
- Function: Prosenchyma provides mechanical support and strength to the plant. It helps in maintaining the shape and structure of the plant organs.
- Cell Structure: Prosenchyma cells have thick and lignified cell walls, which provide rigidity and support. The thickening of cell walls is due to the deposition of secondary cell wall materials like lignin.
- Shape: Prosenchyma cells are long and tapering, with pointed ends. This shape allows them to provide support to the plant tissues.
- Examples: Prosenchyma cells are found in the vascular tissues of plants, such as xylem and phloem.
In conclusion, prosenchyma is a type of plant tissue that provides mechanical support and strength to the plant. It has elongated and tapering cells with thick cell walls.

Answer

Prosenchyma: A Type of Plant Tissue
Prosenchyma is a type of plant tissue that falls under the category of simple permanent tissues. Let's delve into the characteristics and functions of prosenchyma.

Definition of Prosenchyma
- Prosenchyma is a type of plant tissue that consists of long and narrow cells with thick walls.
- These cells are usually dead at maturity and provide mechanical support to the plant.

Characteristics of Prosenchyma
- Prosenchyma cells have thick secondary cell walls, which are usually lignified.
- The cells are elongated and have pointed ends.
- They do not have intercellular spaces.
- Prosenchyma cells are rigid and provide structural support to the plant.

Functions of Prosenchyma
- The primary function of prosenchyma is to provide mechanical support to the plant.
- It helps in maintaining the rigidity and strength of the plant tissues.
- Prosenchyma cells also aid in the conduction of water and nutrients throughout the plant.

Examples of Prosenchyma
- Fiber cells in the xylem tissue of plants are an example of prosenchyma.
- Sclerenchyma fibers are another example of prosenchyma tissue found in plants.
In conclusion, prosenchyma is an essential type of plant tissue that plays a crucial role in providing structural support and aiding in the conduction of water and nutrients in plants. Its unique characteristics and functions make it a vital component of plant anatomy.
