The motile bacteria are able to move by
1. fimbriae
2. flagella
3. cilia
4. pili
The arrangement of outer and central microtubules in a cilium is called the:
1. 9 + 1 pattern
2. 9 + 0 pattern
3. Flagellin pattern
4. 9 + 2 pattern
Both cilium and flagellum arise from the part which is structurally similar to
1. | Centriole | 2. | Kinetochore |
3. | Kinetosome | 4. | Centrosphere |
The diagram below is a diagrammatic representation showing
1. Section of a centriole
2. A cartwheel 9 + 0 structure of microtubular organisation
3. Internal structure of an eukaryotic flagella
4. Internal structure of a centrosome
A centriole-like structure, from which the cilium and the flagellum emerge, is the:
1. Centrosome
2. Basal body
3. Axoneme
4. Vimentin
Cilia and flagella resemble in the
1. Microtubular structure
2. Presence of basal granules
3. Mode of action
4. More than one option is correct
Select the correct statement with respect to axoneme of eukaryotic flagella.
1. It is composed of 9 peripheral triplet microfibrils of tubulin proteins.
2. It does not have covering of plasma membrane.
3. Central tubules are enclosed by a central sheath.
4. It gives rise to spindle apparatus during cell division.
Find the incorrect statement:
1. | Plastids found in plant cells and in euglenoids. |
2. | Golgi apparatus is site of formation of glycoproteins and glycolipids. |
3. | Nucleus during interphase has highly extended and elaborate nucleoprotein fibers. |
4. | Centriole Microtubular organization is referred to as the 9 + 2 and it forms basal body of cilia and flagella. |
Mark the incorrect statement
1. | All the cell organelles perform different & specific function. |
2. | Basal body of cilia & flagella in prokaryotes is formed by cytoskeleton. |
3. | Endoplasmic reticulum helps in transport. |
4. | Microbodies are present in both plants and animals. |
