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 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 the function of Blepharoplast?
The blepharoplast appears to act as a microtubule organizing centre during formation of the spindle apparatus in prophase of the 9th division. While it remains at the pole throughout mitosis it does not continue to serve as the focal point for the spindle tubules.
What is basal body in cell?
Basal bodies are barrel-like microtubular structures located near the cell surface that provide the template for the nine-fold symmetry upon which the cilium is assembled. Basal bodies are thought to be involved in many aspects of cell biology, including the organization of cytoskeletal elements such as cilia.
Is kinetoplast and Blepharoplast same?
The kinetoplast divides independently, but with the basal body, before nuclear division. Kinetoplast formerly included parabasal body and blepharoplast in a locomotory apparatus but is now recognized as a distinct organelle of most trypanosomatids. See also: parabasal body.
What is Kinety and Kinetodesmata?
Kinety system is present in ciliates. In the kinety system, the unit of the structure comprises of kinetosomes and kinetodesma. Kinetosome is the basal granule of the cilia and flagella. Kinetodesma is a strand running from the kinetosomes. Thus, the correct answer is option C.
What are basal bodies made of?
The basal body was named by Theodor Wilhelm Engelmann in 1880 It is formed from a centriole and several additional protein structures, and is, essentially, a modified centriole. The basal body serves as a nucleation site for the growth of the axoneme microtubules.
What is basal granule?
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 meant by kinetoplast?
: a DNA-containing organelle especially of trypanosomes usually found in an elongated mitochondrian located adjacent to the basal body.
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.
