Solution
Parenchyma tissue:
Parenchyma tissue is made up of thin-walled cells and is found in photosynthetic tissues such as leaves, fruit pulp, and the endosperm of many seeds.
A parenchyma is a form of simple permanent tissue that makes up the majority of plant ground tissues.
They are non-vascular and are made up of basic, live, undifferentiated cells that have been changed to serve diverse purposes.
The parenchyma is an important component of structures.
The parenchyma contains live cells.
The nucleus and protoplast are prominent in the cells.
Nature of cells:
The cells of parenchyma tissue are often isodiametric in form.
They might be circular, oval, spherical, elongated, or polygonal.
These cells are either densely packed or have a short intercellular gap.
They are composed of thin cell walls consisting of cellulose and hemicellulose.
Plasmodesmata connect the cells of the parenchyma tissue.
They have multiple tiny vacuoles. Smaller vacuoles coalesce to form a big central vacuole in the older parenchyma, which might contain anthocyanin or tannins.
Water is plentiful in the vacuoles of the parenchyma cells, which serve as a water reservoir.
The hydraulic characteristic of cells provides the parenchyma with its mechanical strength.
Chloroplasts are photosynthesis-specific cells found in the parenchyma.
Chromoplasts can be found in the parenchyma cells of flowers and fruits.
Storage In the endosperm of the date palm, parenchyma cells may contain thick xyloglucan walls. During germination, the sugar is utilized, and the walls become thin.
The secretory parenchyma cells feature thick protoplasm that is rich in ribosomes, Golgi bodies, and a well-developed endoplasmic reticulum.
