Of the following which one is non-cellular in most cases in animals?
Correct answer: A. Mesenchyme
- A. Mesenchyme
- B. Sclerenchyma
- C. Chlorenchyma
- D. Mesoderm
Explanation
Mesenchyme is a loose, gelatinous supporting material that may be largely non-cellular in simple animals such as sponges, although mesenchyme in higher animals contains cells. Students may choose b because mature sclerenchyma cells are dead and lack protoplasm, but sclerenchyma is a plant tissue, not an animal tissue.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
