Question

Parenchyma is a type of_______________
A)Connective tissue
B)Nervous tissue
C)Complex tissue
D)Simple tissue

Answer 1

Hint: The bulk of leaves, buds, and the growing, dividing inner sections of stems and roots constitute plant parenchyma cells. They perform such functions as photosynthesis, storing of food, secretion of sap, and exchange of steam.

Complete answer:
The tissue that connects, divides, and protects all other types of tissues in the body is connective tissue. It consists of cells, like all types of tissues, surrounded by a fluid compartment called the extracellular matrix (ECM). The hippocampus, spinal cord, and muscles are made up of nervous tissue. It is responsible for organizing the various functions of the body and for governing them. The complex tissue consists of more than one type of cell that acts together as a unit. In transporting organic matter, water, and minerals up and down the plants, diverse tissues assist.
Simple tissues are homogeneous and consist of cells similar to structurally and functionally. These are parenchyma, collenchyma and sclerenchyma in three varieties. Parenchyma cells are cytoplasm-filled and have a prominent nucleus. These are in a state of continuous separation.

Parenchyma is the tissue that fills the interior of the body of a flatworm, which is an acoelomate, made up of cells and intercellular spaces. This is a spongy tissue, also known as mesenchymal tissue, in which the extracellular matrices of several types of cells are located. Myocytes and many types of specialised cells are included in the parenchymal cells. The cells are also bound primarily by gap junctions and hemidesmosomes to each other and often to their nearby epithelial cells. Depending on the species and anatomical regions, there is a lot of variation in the types of cells in the parenchyma. Skeletal protection, nutrient storage, activity, among many others can be part of its potential functions.

Hence, the correct answer is option (D)

Note: Parenchyma tissue cells are isodiametric. In between the cells, intercellular spaces are present. Parenchymatous cells with a nucleus have a large central vacuole and peripheral cytoplasm.
