Define nucleoplasm |
| Answer» The nucleoplasm includes the chromosomes and nucleoli. Many substances such as nucleotides and enzymes, which direct activities that take place in the nucleus are dissolved in the nucleoplasm. The soluble, liquid portion of the nucleoplasm is called the nucleosol or nuclear hyaloplasm.Nucleoplasm also called nuclear sap or karyoplasm. Other functions of nucleoplasm include the maintenance of nuclear shape and structure, and the transportation of ions, molecules, and other substances important to cell metabolism and function. | |

Note on double fertilization |
|
Answer» Double fertilization is the joining of a female gametophyte with two male gametes. One sperm fertilizes the egg cell and the other sperm combines with the two polar nuclei of the large central cell of the embryo sac.This helps in providing enough nutrition to the embryo during seed germination. NEET QUESTION 2018What is double fertillization?Answer read as"Syngamy+Triple fusion".WhereSyngamy is fusion of egg cell and generative male nucleus,which results in formation of diploid zygote (2n).ANDTriple fusion is fusion of binucleate polar cell (2n) and male vegetative nucleus,which results in formation of triploid(3n) primary endosperm nucleous (PEN). |

Explain life cycle of angiosperm |
|
Answer» Thanks There is alternation of generations between haploid gametophyte (male gametophyte and female gametophyte) and diploid sporophyte (main plant body) in the life cycle of a plant.The anthers, which contain microsporangia, produce microspores by meiosis, and the microspores develop into male gametophytes called pollen.The ovaries, which posses megasporangia simultaneously produce megaspores which grow into female gametophytes, called ovules. It is a seven celled structure with one large central cell containing two polar nuclei and one egg cell.By the process of pollination, the pollen is transferred to the stigma of the pistil. The pollen grain germinates and a pollen tube grows down into the ovary. Eventually, two sperm nuclei travel down the pollen tube. One sperm nuclei fertilizes the egg forming zygote (which grows into an embryo) and the other two polar nuclei forming triploid cell (endosperm) which often serves as food for the embryo. This is called\xa0double fertilization. The Zygote which begins the next sporophyte generation, on complete development forms a seed. When the seed germinates, the sporophyte matures and the life cycle begins again.\xa0 |

|
Answer» Do bar fretillisation is called double fretilisation.It occours in plant reproduction.

What is functional significance of kranz anatomy? |
| Answer» The word\xa0Kranz\xa0means “wreath” or “ring”.\xa0Kranz anatomy\xa0is a specialized structure in C4\xa0plants where the mesophyll cells\xa0are\xa0clustered around the bundle-sheath cells in a ring-like fashion. The number of chloroplasts in the bundle-sheath cells is more than that in the mesophyll cells.\xa0The\xa0anatomy\xa0wherein there are large, bundle sheath cells around the vascular bundles of C4 pathway plants. The bundle sheath cells form several cells around the vascular bundles. They have a large number of chloroplasts. They have thick walls that are impervious to gaseous exchange.\xa0The primary\xa0function\xa0of\xa0Kranz anatomy\xa0is to provide a site in which CO2 can be concentrated around RuBisCO, thereby avoiding photorespiration. | |

What is functional significance of kranz |
| Answer» The particularly large cells around the vascular bundles of the C4\xa0pathway plants are called bundle sheath cells, and the leaves which have such\xa0anatomy\xa0are said to have \'Kranz\'\xa0anatomy.\xa0Kranz\' means \'wreath\' and is a reflection of the arrangement of cells.\xa0The primary\xa0function\xa0of\xa0Kranz anatomy\xa0is to provide a site in which CO2 can be concentrated around RuBisCO, thereby avoiding photorespiration. | |

What is haplontic |
| Answer» Haplontic\tSporophytic generation is represented only by the one-celled zygote and free-living sporophytes are absent.\tHaploid spores are formed by meiosis, which divide mitotically to form the gametophyte.\tThe dominant, photosynthetic phase in such plants is the free-living gametophyte.Examples-Volvox, Spirogyra and some species of Chlamydomomas. | |
