Single membrane-bound organelles are

Options

A. lysosomes
B. sphaerosomes
C. glyoxysomes
D. all of these

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for examples of single membrane-bound organelles. These are organelles that have only one lipid bilayer surrounding them.

2. **Identifying Single Membrane-Bound Organelles**: The video mentions three specific organelles:
- **Glycosomes**: These organelles contain digestive enzymes and are involved in the digestion of worn-out cell organelles.
- **Spherosomes**: These are involved in the synthesis and storage of lipids and fatty acids, functioning similarly to peroxisomes found in animal cells.
- **Glyoxysomes**: These organelles play a crucial role during the germination of seeds by breaking down fatty acids into sugars, which can be used by the developing plant until it can perform photosynthesis.

3. **Conclusion**: Since Glycosomes, Spherosomes, and Glyoxysomes are all single membrane-bound organelles, the correct answer to the question is "all of these."

### Final Answer:
Single membrane-bound organelles include Glycosomes, Spherosomes, and Glyoxysomes. Therefore, the answer is "all of these."
