The usual position of the two centrioles in relation to each other is at right angle in:
- A
Higher plant cells
- B
Lower plant cells
- C
Animals cells
- D
Both (B) &(C)
Only lower plant cells and animal cells have centrioles at right angle to each other so correct option is D
Centrioles are absent in higher plants because Plant cells have spindle fibre outside the nuclear envelope so they do not need centriole during cell division.
Animal cells and cells of some microscopic organisms and lower plants contain two centrioles that are at right angles to one another.
Animal cells and cells of some microscopic organisms and lower plants contain two centrioles that are at right angles to one another.
Animal cells and cells of some microscopic organisms and lower plants contain two centrioles that are at right angles to one another. Centrioles are located near the surface of the nucleus.
