Define matobolism In word |
|
Answer» All chemical processes occuring inside our body is metabolism. The sum total of all biochemical reactions taking place within the body of an organism which indirectly stimulates the occurrence of life processes is known by the term METABOLISM. It is a combination of CATABOLISM (breakdown) and ANABOLISM (combination). The prosses in which the chemical reaction takes place is called metabolism Energy or biochemical reactions |

Explain about nucleus of a cell |
|
Answer» In cell biology, the nucleus is a membrane-bound organelle found in eukaryotic cells. Eukaryotes usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many. The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm; and the nuclear matrix (which includes the nuclear lamina), a network within the nucleus that adds mechanical support, much like the cytoskeleton supports the cell as a whole.The cell nucleus contains all of the cell\'s genome, except for the small amount of mitochondrial DNA and, in plant cells, plastid DNA. Nuclear DNA is organized as multiple long linear molecules in a complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are structured in such a way to promote cell function. The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression—the nucleus is, therefore, the control center of the cell. In the eukaryotic cell - _It is an organelle _ enclosed by nuclear membrane _ it contains most of cell\'s genetic material. FUNCTION:-_The nucleus controls and regulates the activities of the cell (e.g., growth and\xa0metabolism) . _ carries the\xa0genes, structures that contain the hereditary information. |

Why REPRODUCTION is not a defining property ? |
|
Answer» Reproduction is the ability to produce younger ones. It cannot be considered as a defining property of the living organism because in unicellular organism the increase in number of cells\xa0is considered as growth as well reproduction.\xa0Mule is a cross of female horse and a male donkey cannot produce fertile offspring though they are living. Many organism not have ability to reproduce Ex mules,worker bees ?can\'t reproduce the individual But reproduction is characteristic features of living Because each organism can\'t produce such as Mules , working bees and in humans too they are infertile parents . Because some living organisms can\'t reproduce As many organism do not reproduce.Eg. Mules, Worker bees etc. |

Psuedocoelomate ? |
|
Answer» Before have a idea about coelom! In some protostomes, the embryonic blastocoele persists as a body cavity. These protostomes have a fluid filled main body cavity unlined or partially lined with tissue derived from mesoderm.This fluid-filled space surrounding the internal organs serves several functions like distribution of nutrients and removal of waste or supporting the body as a hydrostatic skeleton.A pseudocoelomate or blastocoelomate is any invertebrate animal with a three-layered body and a pseudocoel. The coelom was apparently lost or reduced as a result of mutations in certain types of genes that affected early development. Thus, pseudocoelomates evolved from coelomates.[14] "Pseudocoelomate" is no longer considered a valid taxonomic group, since it is not monophyletic. However, it is still used as a descriptive term.Important characteristics:lack a vascular blood systemdiffusion and osmosis circulate nutrients and waste products throughout the body.lack a skeletonhydrostatic pressure gives the body a supportive framework that acts as a skeleton.no segmentationbody wallepidermis and muscleoften syncytialusually covered by a secreted cuticlemost are microscopicparasites of almost every form of life (although some are free living)eutely in someloss of larval stage in somepossibly pedomorphism Invertebrate organisms whose body cavity is not derived from a MESODERM, as in coelomates, and thus, have pseudocoels are called PSEUDOCOELOMATES. Eg :- roundworms. |

Why three reasons fail of the two kingdom system ? |
|
Answer» Right Several Objections have been raised against this two Kingdom classification. They are as following:1) First formed organisms were neither plants nor animals.2) Fungi differ in the structure, physiology and reproductive details from plants.3) At the lower level of organisations there are several instances where the distinction of plants and animals actually vanish. For example, Euglena has both holophytic and holozoic nutrition and saprobic nutrition (mixotrophic nutrition or mixed form of feeding). Sponges are branched, fixed and irregular in outline just like plants. It\'s relatives have both holophytic and holozoic nutrition. Unicellular algae like Chlamydomonas are motile, possess regular shape, definite growth and photosynthetic organelles.4) Groups of Unicellular algae (euglenoids, diatoms and dinoflagellates) and protozoa show sufficient degree of resemblance. |

How do living thing grow?explain term growth in living beings |
|
Answer» Growing is capable to a certain living organism. Growth means getting larger in size, and for multi-cellular organisms this is done by making more cells. Plants have special tissues called meristems where growth occurs. Single celled organisms increase their numbers by dividing and making more cells like themselves. Growth occurs internally in living beings |

How many sperms does it need to fertilise one egg. |
|
Answer» 1,because 1sperm fertilise only one egg During fertilization, when the sperm(having acrosome in the head of sperm) come in contact with zona pellucida(layer of ovum), zona pellucida allows to enter only that sperm and prevents the entry of other sperms. Acrosome helps to penetrate the zona pellucida. It needs two sperms because, one of the sperm reacts with the diploid secondary nucleus to form primary endosperm nucleus which is triploid in nature and another sperm reacts with the egg to form zygote.endosperm provide nourishment to developing embryo. 1 |

Full description of Liverworts with Diagram ? |
| Answer» The liverworts grow usually in moist, shady habitats such as banks of streams, marshy ground, damp soil, bark of trees and deep in the woods. The plant body of a liverwort is thalloid, e.g., Marchantia. The thallus is dorsiventral and closely appressed to the substrate. The leafy members have tiny leaf-like appendages in two rows on the stem-like structures.Asexual reproduction in liverworts takes place by fragmentation of thalli, or by the formation of specialised structures called gemmae (sing. gemma). Gemmae are green, multicellular, asexual buds, which develop in small receptacles called gemma cups located on the thalli. The gemmae become detached from the parent body and germinate to form new individuals. During sexual reproduction, male and female *** organs are produced either on the same or on different thalli. The sporophyte is differentiated into a foot, seta and capsule. After meiosis, spores are produced within the capsule. These spores germinate to form free-living gametophytes. | |

Explain gymnosperms |
|
Answer» Gymnosperms:० single fertilisation occur.० endosperm is haploid.० endosperm develop from female gametophore ( before fertilisation).० nacked seeds.० they have pinned leaves.० it includes medium size trees shrubs and tall trees. ( ? Herbs are not included here.) Gymnosperms:Gymnosperms are those plants in which the ovules are not enclosed inside the ovary wall and remain exposed before and after fertilisation.They are perennial and woody, forming either bushes or trees. Some are very large (Sequoia sempervirens) and others are very small (Zamia pygmia).Stem may be unbranched(Cycas) or branched(Pinus). Root is taproot. Leaves may be simple or compound.They are heterosporous, produce haploid microspore and megaspore in male and female Strobili respectively.Male and female gametophytes do not have independent free-living existence. Pollination occurs through air and zygote develops into embryo and ovules into seeds. These seeds are naked.Example- Pines, Cycus, Cedrus, Ginkgo, etc. There no ans you you are losser |
