Centrioles are absent in higher plant cells.
Centrioles: An Overview
Centrioles are cellular structures involved in cell division. They are found in eukaryotic cells, playing a crucial role in organizing microtubules, which form the spindle fibers that separate chromosomes during cell division.
Absence of Centrioles
Based on the provided reference, centrioles are not universally present in all plant cells.
- Centrioles are present in animal cells.
- Centrioles are present in some lower plant cells.
- However, centrioles are absent in all higher plant cells.
Therefore, if the question is specifying a type of organism, the answer is "higher plant cells".
