Question: Centriole is found in ____.
Options:
animal cells
red algae
prokaryotes
flowering plants
Centrioles are the feature of animal cells. They are absent in plant cells.
Centrioles are the cell component that is visible during the cell division stages.
Centrioles are the microtubule-producing organelles engaged in cell division.
It is situated near the nucleus in the cytoplasm.
The centrioles help in the formation of spindle fibers during cell division.
The centriole is made up of nine evenly spaced peripheral fibrils of tubulin protein. Each of the peripheral fibrils is a triplet. The adjacent triplets are also linked.
The central part of the proximal region of the centriole is also proteinaceous and called the hub, which is connected with tubules of the peripheral triplets by radial spokes made of protein. Thus, it shows a 9 + 0 arrangementÂ
The centrioles form the basal body of cilia or flagella, and spindle fibres that give rise to spindle apparatus during cell division in animal cells.🛑Important Points:
Two centriole pair at the right angle to form a structure called Centrosome
​🔴Additional Information::
Red Algae: The members of Rhodophyceae are commonly called red algae because of the predominance of the red pigment, r-phycoerythrin in their body.
The majority of the red algae are marine with greater concentrations found in the warmer areas.
They occur in both well-lighted regions close to the surface of water and also at great depths in oceans where relatively little light penetrates
Animal cell are mostly similar to plant cells but some minor differences include the absence of cell wall, plastids & vacuolesÂ
Flowering plants: The plants which produce flowers, and covered seeds are called flowering plants. All the angiosperms are included in this group
