Flesh of a fruit is mostly made up ofa)Parenchymab)Collenchymac)Sclere...
The correct answer is a.
Parenchyma : It is very primitive type of tissue. It is first evolved tissue. Remaining all different types of tissuesare derived from this tissue. so it is also called as fundamental tissue l Parenchyma name coined by Grew.
CHARACTERISTIC FEATURES :
It is a living tissue.
It is first differentiated tissue derived from meristem.
It is a universal tissue.
Flesh of a fruit is mainly composed of parenchyma.
Body of bryophyte plants is mainly composed of parenchyma.
Parenchyma is most common tissue which is morphologically and physiologically unspecialized.
The cells of parenchyma are thin walled. Cell wall is made up of pectocellulose (mainly cellulose). So parenchyma is a soft tissue.
Each cell containing large central vacuole. So the main function of a parenchyma cell is storage of food.
Usually Inter cellular spaces are present between cells of this tissue, it is a loose tissue. Intercellular spaces are usuallyschizogenous in origin.
The cells are usually isodiametric.

Composition of Fruit Flesh
The flesh of a fruit, also known as the mesocarp, is the edible part of the fruit that surrounds the seeds. It is responsible for the sweet and juicy taste of many fruits. The composition of fruit flesh can vary depending on the type of fruit, but it is mostly made up of parenchyma cells.
Parenchyma Cells
Parenchyma cells are the most common type of plant cells and are found in all parts of a plant, including the fruit. They are characterized by their thin cell walls and large vacuoles. Parenchyma cells are highly versatile and can perform various functions in plants, such as storage, photosynthesis, and secretion.
Functions of Parenchyma Cells in Fruit Flesh
1. Storage: Parenchyma cells in fruit flesh store various nutrients, such as sugars, starches, and organic acids. These stored substances contribute to the taste and nutritional value of the fruit.
2. Water and Nutrient Transport: Parenchyma cells in fruit flesh are involved in the transport of water and nutrients from the vascular tissue to other parts of the fruit. This ensures the proper growth and development of the fruit.
3. Turgidity and Firmness: The large vacuoles in parenchyma cells contribute to the turgidity and firmness of fruit flesh. This gives the fruit its characteristic texture and juiciness.
4. Photosynthesis: In some fruits, such as green tomatoes, parenchyma cells in the fruit flesh can carry out photosynthesis. This allows the fruit to continue producing sugars and other organic compounds even after it has been harvested.
Other Cell Types in Fruit Flesh
While parenchyma cells make up the majority of fruit flesh, there are other cell types present as well, although in smaller quantities. These include:
- Collenchyma: Collenchyma cells provide structural support to the fruit and are often found beneath the skin or in other specific areas.
- Sclereids: Sclereids are specialized cells that provide hardness and protection to the fruit. They are commonly found in fruits with a hard outer shell, such as nuts.
- Meristem: Meristem cells are responsible for the growth and development of the fruit. They are found in the growing tips and can differentiate into various cell types, including parenchyma cells.
In Conclusion
The flesh of a fruit is primarily composed of parenchyma cells, which perform various functions such as storage, transport, turgidity, and photosynthesis. Although other cell types like collenchyma, sclereids, and meristem may be present in smaller quantities, parenchyma cells are the predominant cell type that gives fruit flesh its characteristic taste, texture, and juiciness.
