Question

describe the structure of the following:
1)axoneme
2)centrosome

Answer 1

Answer:

Axoneme--the central strand of a cilium or flagellum. It is composed of an array of microtubules, typically in nine pairs around two single central ones. Centrosome---Centrosomes are organelles which serve as the main microtubule organizing centers for animal cells. Centrosomes are made of from arrangement of two barrel-shaped clusters of microtubules, called “centrioles,” and a complex of proteins that help additional microtubules to form

Answer 2

Answer:

1)  Axoneme:-

                        An axoneme is the microtubule-based cytoskeletal structure that forms the core of a cilium or flagellum.[1] Cilia and flagella are found on many cells, organisms, and microorganisms, to provide motility. The axoneme serves as the "skeleton" of these organelles, both giving support to the structure and, in some cases, the ability to bend. Though distinctions of function and length may be made between cilia and flagella, the internal structure of the axoneme is common to both.

2) Centrosome:-

                       Centrosome has two cylindrical structures called centrioles. Each has a cartwheel-like . A organization centriole is made up of microtubule triplets in a ring. The adjacent triplets are linked together. There is a proteinaceous hub in the central part of a centriole. The hub is connected to the triplets via radial spokes. These centrioles help in organising the spindle fibres and astral rays during cell division. They form the basal body of cilia and flagella as well.
