Question

Peroxisomes, glyoxysomes and spherosomes are examples of

• A. non-membrane bound organelles
• B. single membrane-bound organelles
• C. double membrane-bound organelles
• D. inclusion bodies

Answer 1

The correct option is B single membrane-bound organelles

Peroxisomes, glyoxysomes and spherosomes are single membrane-bound organelles like endoplasmic reticulum, Golgi apparatus, lysosomes.

Peroxisomes are found in both plant and animal cells. In plants, they help in photorespiration. In animals, they help in detoxification of toxic substances.

Glyoxysomes are called special peroxisomes. They can be easily found in germinating seeds. They contain enzymes necessary to convert fats into carbohydrates.

Spherosomes are found in plant cells and help in the synthesis and storage of lipids.

Ribosomes are the non-membrane bound organelles. They are also called protein factories of the cell.

Mitochondria, plastids and the nucleus are double membrane-bound organelles.

Inclusion bodies are the non-living storage components of the cell. They can be found freely suspended and floating in the cytoplasm. Usually, the inclusion bodies contain proteins.
