Cells which are secretory in function have abundant

Options

A. lysosomes
B. endoplasmic reticulum
C. dictyosomes
D. osteosomes.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which type of cell organelle is abundant in cells that have a secretory function.

2. **Analyzing the Options**:
- **Option A: Lysosomes**: These are involved in the digestion of macromolecules and the repair of cell membranes but are not primarily involved in secretion.
- **Option B: Endoplasmic Reticulum (ER)**: The ER is involved in the synthesis, folding, and modification of proteins, as well as their transport. While it plays a role in protein production, it is not specifically known for secretion.
- **Option C: Dictyosomes**: These are cup-shaped structures found in plant cells, known as the Golgi apparatus in other organisms. They are responsible for modifying proteins from the ER, polymerizing sugars to polysaccharides, and packaging materials for delivery, which is crucial for secretion.
- **Option D: Osteosomes**: These are involved in responding to mechanical strain and signaling bone formation, not secretion.

3. **Identifying the Correct Answer**: Based on the analysis, Dictyosomes (Option C) are the organelles that are abundant in secretory cells due to their role in modifying and packaging proteins and polysaccharides for secretion.

4. **Conclusion**: The correct answer is **Option C: Dictyosomes**.
