Large membranous sacs that are more prevalent in plant cells and some protozoa than in animal cells are called :

Options

A. vacuoles
B. vesicles
C. glyoxisomes
D. lysosomes

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of large membranous sacs that are more prevalent in plant cells and some protozoa than in animal cells.

2. **Identifying the Options**: The options provided are:
- A) Vacuole
- B) Vesicles
- C) Glyoxysomes
- D) Lysosomes

3. **Analyzing Each Option**:
- **Vacuole**: These are large, membrane-bound sacs found in plant cells and some protozoa. They are primarily involved in storage of substances such as nutrients, waste products, and other materials.
- **Vesicles**: These are smaller membrane-bound sacs that transport materials within the cell but are not specifically large or prevalent in plant cells.
- **Glyoxysomes**: These are specialized organelles found in plants, primarily involved in the conversion of stored fats into sugars, but they are not large membranous sacs.
- **Lysosomes**: These are membrane-bound organelles that contain enzymes for digestion within the cell, but they are not primarily storage organelles.

4. **Conclusion**: Based on the analysis, the correct answer is **A) Vacuole**. Vacuoles are indeed large membranous sacs that serve as storage compartments in plant cells and some protozoa.

5. **Reasoning**: Vacuoles are larger in plant cells because they store nutrients and waste products, which is crucial for the plant's survival, especially when they cannot photosynthesize (e.g., at night).
