Question

The tissue is defined as a group of
a. Cells which are dissimilar in origin, but are similar in form and function
b. Cells which are similar in origin, but dissimilar in form and function
c. Cells which are dissimilar in origin, form, and function
d. Cells which are similar in origin, form, and function

Answer 1

Tissue is part of the cellular organisation. A large number of cells joined to form the tissue. They perform one or more functions in the body.

Complete answer:
Tissue can be defined as the group of cells which perform a similar function. A large number of cells which have the same form and origin joined to form the tissue. Since all the cells in the specific organ behave similarly, thus, tissue cannot have any dissimilarity in cells.

Hence, the correct answer is option (D).

Additional information:
-There are four types of tissues in humans. These are epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
-Epithelial tissue is present on all the organs of the body. It covers all the surface of the body and performs many functions. The functions performed by the epithelial tissue include absorption, secretion, excretion, and filtration
-There are three types of muscle tissues, and these are cardiac muscle, smooth muscle, and skeletal muscle. The cardiac muscle is the muscle of the heart, and they are under involuntary control.
-Connective tissues are of many types such as loose connective tissue, dense connective tissue, cartilage, bone, and blood. The loose connective tissue includes adipose tissue, areolar tissue, and reticular tissue.
Bone tissue is the hardest connective tissue which supports the body and protects the internal organ.

Note: Tissue is a unit formed by joining the cell. The cell is the structural and functional unit of the body. Tissues form organs, and organs form the organ system in the body.
