Golgi complex is absent in __________

Options

A. Sperms of broyophytes
B. Sieve tubes of plants
C. Matured RBCs of mammals
D. All of these

Answer

To answer the question "Golgi complex is absent in __________", we need to analyze the options provided and determine where the Golgi complex is not present.

### Step-by-Step Solution:

1. **Understanding the Golgi Complex**:
The Golgi complex (or Golgi apparatus) is an organelle involved in the modification, sorting, and packaging of proteins and lipids for secretion or delivery to other organelles. It is found in most eukaryotic cells.

2. **Analyzing the Options**:
- **Option 1: Sperm of Bryophytes**:
Bryophytes, which include mosses and liverworts, have sperm cells that do not contain a Golgi complex. Therefore, this option is correct.

- **Option 2: Sieve Tubes of Plants**:
Sieve tube elements, which are part of the phloem in vascular plants, lack a Golgi complex. This option is also correct.

- **Option 3: Mature Red Blood Cells of Mammals**:
Mature red blood cells (erythrocytes) in mammals do not have a Golgi complex as they lose their organelles during maturation. This option is correct as well.

- **Option 4: All of the Above**:
Since all the previous options indicate cells or structures that do not possess a Golgi complex, this option is also correct.

3. **Conclusion**:
Based on the analysis, the Golgi complex is absent in the sperm of bryophytes, sieve tubes of plants, and mature red blood cells of mammals. Therefore, the answer to the question is that the Golgi complex is absent in all the mentioned options.

### Final Answer:
Golgi complex is absent in **sperm of bryophytes, sieve tubes of plants, and mature red blood cells of mammals**.
