What is the difference between Spirogyra and chlamydomonas |
| Answer» SpirogyraThe male cytoplasm migrates through the conjugation canal, fusing with the female. The rest of the process proceeds as in scalariform conjugation. The essential difference is that scalariform conjugation occurs between two filaments and lateral conjugation occurs between two adjacent cells on the same filament.ChlamydomonasChlamydomonas is a genus of green algae consisting of unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". Chlamydomonas is used as a model organism for molecular biology, especially studies of flagellar motility and chloroplast dynamics, biogeneses, and genetics. One of the many striking features of Chlamydomonas is that it contains ion channels, (channelrhodopsins), that are directly activated by light. Some regulatory systems of Chlamydomonas are more complex than their homologs in Gymnosperms, with evolutionarily related regulatory proteins being larger and containing additional domains. | |

How many types of vascular bandle |
| Answer» A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in vascular tissue, which exists in two forms: xylem and phloem. Both these tissues are present in a vascular bundle, which in addition will include supporting and protective tissues.The following four main types of vascular bundle.\xa01. Collateral Bundle2. Bicollateral Bundle3. Concentric Bundle4. Radial Vascular Bundle. | |

Difference between cytokinesis of plants and cytokinesis in animals. |
| Answer» \tBASIS OF COMPARISONCYTOKINESIS IN PLANTSCYTOKINESIS IN ANIMALSDescriptionThe process of division of the cytoplasm in the plant cell is what is referred to as Cytokinesis in the plant cell. The process of division of cytoplasm in an animal cell is what is referred to as Cytokinesis in animal cell. How It BeginsIt starts with the formation of cell plate during telophase. It starts as a constriction in the cell membrane during late anaphase or early telophase. Cell Plate FormationVesicles fuse to form cell plate. A cell plate is not formed. Spindle ApparatusThe middle part of the spindle remains active during Cytokinesis in a plant cell. It forms a complex referred to as phragmoplast. During Cytokinesis in an animal cell, spindles degenerate. Process Of CytokinesisIn plant Cytokinesis, cell plate formation takes place to divide cytoplasm into two daughter cells. Cytokinesis in the animal cell takes place through cleavage. DivisionIn plant cell Cytokinesis, the cell plate develops from the center of the cell towards the lateral walls. Therefore, it is described as centrifugal. In animal cell Cytokinesis, the furrow starts to deepen from the lateral /periphery sides of the cell towards the center. Therefore, it is known as centripetal. Row Of VesiclesA row of vesicles is formed in the center of the cell during plant cell Cytokinesis. There is no row of vesicles that form during animal cell Cytokinesis. MicrofilamentsMicrofilaments play a little role in plant cell Cytokinesis. In animal cell Cytokinesis, microfilaments are very actively involved. Mid BodyA mid body is absent in plant cell Cytokinesis. A mid body of dense fibrous and vesicular material is formed in the middle. New Cell MembraneThe new cell membrane is derived from vesicles of Golgi apparatus. The new cell membrane is usually derived from endoplasmic reticulum. \t | |

Component of bacterial flagela |
| Answer» A bacterial flagellum has 3 basic parts: a filament, a hook, and a basal body.1) The filament is the rigid, helical structure that extends from the cell surface. It is composed of the protein flagellin arranged in helical chains so as to form a hollow core. During synthesis of the flagellar filament, flagellin molecules coming off of the ribosomes are transported through the hollow core of the filament where they attach to the growing tip of the filament causing it to lengthen. With the exception of a few bacteria, such as Bdellovibrio and Vibrio cholerae, the flagellar filament is not surrounded by a sheath.2) The hook is a flexible coupling between the filament and the basal body .3) The basal body consists of a rod and a series of rings that anchor the flagellum to the cell wall and the cytoplasmic membrane. Unlike eukaryotic flagella, the bacterial flagellum has no internal fibrils and does not flex. Instead, the basal body acts as a rotary molecular motor, enabling the flagellum to rotate and propel the bacterium through the surrounding fluid. In fact, the flagellar motor rotates very rapidly. (Some flagella can rotate up to 300 revolutions per second!)The MotA and MotB proteins form the stator (def) of the flagellar motor and function to generate torque for rotation of the flagellum. The MS and C rings function as the rotor (def). Energy for rotation comes from the proton motive force (def) provided by protons | |
