Question

. Write four characteristics features of Parenchyma a tissues. How would you classify tissue based upon its specialized functions? What are these functions?

Answer 1

. These tissues are mainly concerned in storage of food.

2. In fleshy stem, they act as water storage tissues.

3. In hydrophytes large air cavities are formed in-between these tissues. These types of tissues are called aerenchyma.

4. In leaf, these tissues contain chloroplasts and help in photosynthesis and are called collenchyma.

5. Sometimes these tissues become meristamic and form cork cambium and cambium in root. Thus, they help in secondary growth.

Classifications of Tissues:
The human body is composed of four basic types of tissues; epithelium, connective, muscular, and nervous tissues.
These tissues vary in their composition and their function. A basic understanding of the role of each tissue makes
understanding the specific functions easier.
1. Epithelium- lines and covers surfaces
2. Connective tissue- protect, support, and bind together
3. Muscular tissue- produces movement
4. Nervous tissue- receive stimuli and conduct impulses
Now that we have an understanding of the basic roles of the tissues, we turn our focus to a more thorough investigation of
the form and function of the different types of tissues in the human body.
hope this helps you
