Which structure is normally absent from the cells of higher plants?
Correct answer: A. Centrioles
- A. Centrioles
- B. Mitochondria
- C. Golgi apparatus
- D. Ribosomes
Explanation
Higher plant cells organise their spindle without centrioles, which is why the presence of a pair of centrioles beside the nucleus is taken as an animal cell feature in a diagram question. Centrioles are present in animal cells and in the motile cells of lower plants. Mitochondria, Golgi and ribosomes are common to both kingdoms.

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.
