What is Kinetosome and Kinetodesma?
Kinetosome is the basal granule of the cilia and flagella. Kinetodesma is a strand running from the kinetosomes.
What is the function of Kinetosome?
Zoospore development in the oomycetes The kinetosome is located at the base of the flagella and is the microtubule organising centre for flagellar microtubules.
What is the meaning of Kinetosome?
(kɪˈnɛtəˌsəʊm; kɪˈniːtəˌsəʊm; kaɪˈnɛtəˌsəʊm; kaɪˈniːtəˌsəʊm) n. (Biology) a structure in some flagellate protozoans which forms the base of the flagellum, consisting of a circular arrangement of microtubules.
What is a Kinety?
Hint: A kinety is an arrangement of filaments and microtubules emerging from the basal bodies or kinetosomes that associates it to its neighboring filament in the kinety and nearby hairy columns. They are straight longitudinal arrows that contain two kinds of nuclei and two copies of each chromosome.
What is Blepharoplast in biology?
A basal body or blepharoplast is an organelle formed from a centriole, and a short cylindrical array of microtubules. It is found at the base of a eukaryotic undulipodium and serves as a nucleation site for the growth of the axoneme microtubules.
What is the sliding microtubule hypothesis?
What is the sliding-microtubule hypothesis? Movement is powered by the release of chemical bond energy in ATP. When bond energy in ATP is released, the arms “walk-along” one of the microtubules in the adjacent pair, causing it to slide relative to the other tubule.
What is flagella axoneme?
The axoneme is the main extracellular part of cilia and flagella in eukaryotes. It consists of a microtubule cytoskeleton, which normally comprises nine doublets. In primary cilia, there are a number of sensory proteins functioning on membranes surrounding the axoneme.
What are basal granules?
Basal granule –> basal body. (Science: cell biology) structure found at the base of eukaryotic cilia and flagella consisting of a continuation of the nine outer sets of axonemal microtubules but with the addition of a c tubule to form a triplet (like the centriole).
What is kinetoplast and Blepharoplast?
The kinetoplast is a disc shaped organelle (ca. The blepharoplast is generally regarded as the starting point of the flagellum and it has long been known that the blepharoplast and the kinetoplast are intimately related (1). Both these organelles reproduce by bipartition at the onset of cell division.
Are cilia?
Cilia are small, slender, hair-like structures present on the surface of all mammalian cells. They are primitive in nature and could be single or many. Cilia play a major role in locomotion. They are also involved in mechanoreception.
