Question

Read the given statements.
1. Many nerve cells bound together by connective tissue make up a nerve.
2. Areolar connective tissue fills the space inside the organs and helps in repair of tissues.
3. Glandular epithelium is formed by in folding of epithelial tissue.
4. Smooth muscle fibres show characteristic of both striated and unstriated muscles.
5. Skin epithelial cells are extremely thin and flat through which absorption and secretion occur.

Select the incorrect statements.

(a) 4 and 5 (b) 1, 3 and 5 (c) 1, 2 and 3 (d) 2, 3 and 4

Answer 1

Answer:

Many nerve cells bound together by connective tissue make up a nerve. 2. Areolar connective tissue fills the space inside the organs and helps in repair of tissues. ... Skin epithelial cells are extremely thin and flat through which absorption and secretion occur.

Answer 2

The incorrect statements are (a) 4 and 5

1. Many nerve cells bound together by connective tissue make up a nerve. - Correct

Nerve cell is about one metre long. And many such nerve cells bound together form a nerve.

2. Areolar connective tissue fills the space inside the organs and helps in repair of tissues. - Correct

Areolar connective tissue fills up the space inside the organs and provides support to the internal organs. It also helps in tissue repair.

3. Glandular epithelium is formed by in folding of epithelial tissue. - Correct

As the epithelial tissue folds inward, a multicellular gland is formed and this tissue is called glandular epithelium.

4. Smooth muscle fibres show characteristic of both striated and unstriated muscles. Incorrect

Smooth muscle fibres show characteristic of unstriated muscles. While skeletal muscle shows characteristics of striated muscles.

5. Skin epithelial cells are extremely thin and flat through which absorption and secretion occur. - Incorrect

Skin epithelial cells are extremely thin and flat as it has simple squamous epithelium. But, no absorption or secretion occurs through these cells. Therefore, this statement is incorrect.
