Explain the process by which cork is formed in trees. Along with the diagram |
| Answer» \tThe first cork cambium is formed by the dedifferentiation of the outer part of the cortex.\tAs the stem increases in girth, the epidermis and the cortex are replaced by another meristematic tissue called the cork cambium.\tIt is also called phellogen.\tThe cells of the phellogen are thin-walled, rectangular and narrow.\tThe cork cambium is 2–3 layers thick.\tCells of the cork cambium cuts off cells peripherally and towards the centre.\tCells on the peripheral region form the cork cambium or phellem.\tThe walls of cork cells have depositions of suberin because of which cork becomes impermeable to water.\tCells on the inner region form the secondary cortex or phelloderm. The cells of this region are parenchymatous. | |

Graveyard of RBCs |
|
Answer» Percentage composition? The average lifespan of RBCs is 120 days. RBCs are finally destroyed in the spleen and hence, spleen is also called the graveyard of RBCs. RBCs play a significant role in transport of respiratory gases. Spleen is an organ of the lymphatic system located in the left side of the abdominal cavity under the diaphragm, the muscular partition between the abdomen and the chest. It is called graveyard of RBC because fragment of red blood cells, old and dead cells are constantly being removed from the blood streams by it. |

What do you understand by glycocalyx |
| Answer» Glycocalyx are the carbohydrate coating on the surface of prokaryotic or eukaryotic cells. Glycocalyx are the recognition moieties which help cells to recognise each other. These can either be glycolipids or glycoproteins projecting from the cell membrane. It cushions the plasma membrane and protects it from injury. glycococalyx also help cells in binding with each other and they also play a great role in immunity as the immune system of our body recognises these glycoproteins to produce antibodies. | |

What happens to cell in absence of lysosome???? |
| Answer» \xa0Lysosomes are called\xa0‘suicide bags of the cell’ are membrane bound organelles containing hydrolytic enzymes.In their absence the following might result:\tCancer. Cells need to die once they have divided a certain amount of times as they gather genetic damage. Cells which continue to live past their lifespan will accumulate enough mutations to become cancerous.\tImpaired immunity. Cell mediated immunity will take a hit as lysosomes are responsible for the digestion of ingested pathogen (lysosome fuses with phagosome) by phagocytes like macrophages and the subsequent presentation of processed peptides to activate humoral immunity.\tMetabolic diseases. Synthesis of certain bio-molecules will be affected as catabolic enzymes required for breaking of complex bio-molecules into simpler ones are absent without the presence of lysosome. | |

What is triple fertilization? |
| Answer» Triple fusion is a fusion that involves a sperm nucleus and two polar nuclei which occurs in the double fertilization in a seed-bearing plant that results in the endosperm formation. ... One of the two male gametes fuses with the nucleus of the egg cell to produce the zygote, this process is referred to as syngamy.\xa0Triple fusion\xa0is defined as\xa0fusion taking place\xa0between two polar nuclei and sperm nucleus. This happens during double fertilization in a seed plant, and therefore gives origin to a triploid nucleus known as the Primary Endosperm Nucleus(PEN). The PEN later evolves into an endosperm. | |

what is autoclaving and how it is used to kill viruses?? |
| Answer» Autoclaves provide a physical method for disinfection and sterilization. They work with a combination of steam, pressure and time. Autoclaves operate at high temperature and pressure in order to kill microorganisms and spores.They are used to decontaminate certain biological waste and sterilize media, instruments and lab ware. Regulated medical waste that might contain bacteria, viruses and other biological material are recommended to be inactivated by autoclaving before disposal. | |

What is alternation of generation? |
| Answer» Alternation of generations, also called metagenesis or heterogenesis, in biology, the\xa0alternation\xa0of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or\xa0generations, are often morphologically, and sometimes chromosomally, distinct.\xa0The fern is an\xa0example of alternation of generations, in which both a multicellular diploid organism and a multicellular haploid organism occur and give rise to the other. ... The large, leafy fern is the diploid organism. On the undersurface of its fronds or leaves, its cells undergo meiosis to create haploid cells. | |

Often the body of fungi is not noticed until it\xa0forms\xa0a fruiting body.\xa0A\xa0hypha\xa0consists of one or more cells surrounded by a tubular cell wall. ... The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have\xa0aseptate hyphae, meaning their\xa0hyphae\xa0are not partitioned by septa. | |

why bacteria as a group shows the most extensive metabolic diversity??? |
| Answer» The\xa0bacteria\xa0is known to have the\xa0most extensive metabolic diversity\xa0because it is able to extract energy from any carbohydrate which is in its reduced form like sugar. It does that as it has different compounds which have different inorganic or organic reduced electron compounds.\xa0Bacteria as a group\xa0show most extensive metabolic diversity. Extensive metabolic diversity means\xa0that the reactions consume or conduct a lerge amount of f9od material for reactions. | |
