The functions of epithelial tissue is/are
( a ) Protection
( b ) Absorption and secretion
( c ) Production of gametes
( d ) Transcellular transport

Options

A. (a) , (b) & ( c ) Only
B. (a) & (b) Only
C. (a) , (b) , ( c ) & (d)
D. (a) Only

Answer

To determine the functions of epithelial tissue, we will analyze each option provided in the question:

1. **Protection**:
- Epithelial tissue serves as a protective barrier. It can be found in layers, such as in the skin, where it protects underlying tissues from mechanical and chemical damage.
- **Conclusion**: This function is correct.

2. **Absorption and Secretion**:
- Epithelial tissues can also be specialized for absorption and secretion. For example, in the intestines, epithelial cells absorb nutrients, and glandular epithelium produces secretions such as mucus and enzymes.
- **Conclusion**: This function is correct.

3. **Production of Gametes**:
- Epithelial cells can give rise to germ cells, which undergo meiosis to produce gametes (sperm and eggs). The process of gametogenesis begins with epithelial cells in the reproductive system.
- **Conclusion**: This function is correct.

4. **Transcellular Transport**:
- Epithelial tissues can facilitate transcellular transport, allowing substances to move through the cells. This is often aided by specialized junctions between epithelial cells that allow for communication and substance exchange.
- **Conclusion**: This function is correct.

After analyzing all four options, we find that all of them are indeed functions of epithelial tissue.

**Final Answer**: All options (a, b, c, d) are correct.
