If prokaryots does not have organelles then how cynobacteriya contain choroplast |
| Answer» Chloroplasts are major organelles. They contain green pigments that make plants green. They are often called plastids, though plastids and chloroplasts are not exactly the same thing—a chloroplast is a special kind of plastid that photosynthesizes. Chloroplasts do lots of things, but their main function is photosynthesis.Plant cells, and some protists have chloroplasts, though animal and fungal cells lack them. Prokaryotes do not have chloroplasts (or any other organelles), though some can carry out photosynthesis, its cell acting like one big chloroplast. Chloroplasts are mainly green in colour since it absorbs red and blue light via their green pigment chlorophyll that is present in the thylakoid membranes.(Refer to wikibooks.org for more information)Chloroplasts are cellular generators. They take in carbon dioxide and water, and release sugar and oxygen. This process is called photosynthesis. Mitochondria then use the sugar and oxygen to carry out cellular respiration, producing energy.Mitochondria are essential parts of many eukaryotes, but they are useless without oxygen. Therefore, chloroplasts are extremely important. They produce breathable air for life.Root hairs are seen to not have chloroplasts as their job is to collect water and nutrients. They do NOT carry out photosynthesis.Like mitochondria, chloroplasts have their own DNA. Scientists also think chloroplasts are descended from a kind of bacteria, called cyanobacteria. Cyanobacteria are the photosynthetic bacteria we mentioned earlier. In early stages of Earth, cyanobacteria produced oxygen for their friends, the ærobic bacteria (ærobic means they use oxygen). Some of these ærobic bacteria later migrated into a eukaryotic cell, becoming mitochondria. The cyanobacteria followed, becoming chloroplasts. All eukaryotic cells contain mitochondria, but only plants and algæ contain chloroplasts, so scientists think mitochondria came first. | |

In which phase of cell cycle DNA replication takes place |
|
Answer» S phase S phase of interkinesis DNA replication takes place in \'S\' Phase (of interphase). Cell division is a very important process in all living organisms. During the division of a cell, DNA replication and cell growth also take place. All these processes, i.e., cell division, DNA replication, and cell growth, hence, have to take place in a coordinated way to ensure correct division and formation of progeny cells containing intact genomes. |

What is plasmolycis |
|
Answer» Plasmolysis is when plant cells lose water after being placed in a solution that has a higher concentration of solutes than the cell does. This is known as a hypertonic solution. Water flows out of the cells and into the surrounding fluid due to osmosis. When plant cell loses water through osmosis, the content of cell(including cell membrane )shrinks away from the cell wall , this process is known as plasmolysis.It is a reversible process. |

Different tyoes of bonds i) pepstideosidic bond ii) glycisidic bond iii) phospho diester bond |
|
Answer» GLYCOSYDIC BOND:It is the bond linking the monosaccharides(monomers) in polysaccharides(polymer). It is also formed by dehydration. Peptide bond : This bond forms between the amino group of one amino acid and the carboxlic group of another amino acid with the removal of water.Hence it is formwd by dehydration.(H--N--H------------OH--C--O), Phosphodiester bond:A phosphate group is connected with the 5th carbon of one ribose sugar(in nucleotide) to the 3rd carbon of another ribose sugar(in anothe nucleotide) , the bond between phoshate group and the sugar is known as ester bond and there are two such ester bonds,So it is called Phosphodiester bond.It is also formed by dehydration. |

Plant reproductive system |
| Answer» Plant reproductive system, any of the systems, sexual or asexual, by which plants reproduce. In plants, as in animals, the end result of reproduction is the continuation of a given species, and the ability to reproduce is, therefore, rather conservative, or given to only moderate change, during evolution. | |

Difference between anaphse of metosisand anaphase I of meiosis |
| Answer» \tAnaphase of MitosisAnaphase I of Meiosis1. The centromere of every chromosome divides.1. The centromere do not divide.2. Separation of sister chromatids takes place.2. Homologus chromosome are separated.3. Only one chromatids of every chromosome moves to the pole (now called daughter chromosome).3. Each homologous pair of chromosomes moves to the pole with both the chromatids.4. The chromatids moving to one pole are genetically identical to those moving to the opposite pole (Before separation, these are sister chromatids held at a common centromere).4. The chromosomes moving to one pole are not genetically indentical to those moving to the opposite pole.\t | |

Plant golgi body is dictyosomes |
| Answer» The Golgi apparatus was first described by Camillo Golgi. Golgi apparatus consists of a set of membrane-bounded, fluid filled vesicles, vacuoles and flattened cisternae. Cisternae are usually stacked together (placed one above the other) in parallel rows. Golgi apparatus exists as an extensive network near the nucleus in the animal cells. However, the plant cells contain many freely distributed subunits of Golgi apparatus, called dictyosomes. The Golgi apparatus arises from the membrane of the smooth endoplasmic reticulum, which in turn, originates from the rough endoplasmic reticulum. | |

Describe - haplontic ,diplontic , haplodiplontic |
| Answer» Haplontic- sporophytic generation is\xa0represented by one celled zygote. There are no free living sporophytes. Meiosis in the zygotes results in the formation of haploid spores. The haploid spores divide mitotically and form gametophyte. The dominant photosynthetic phase in such plants is free living gametophyte. This kind of life cycle is haplontic.Diplontic-\xa0Diploid sporophyte is dominant photosynthetic phase. The gametophyte phase is represented by single to few celled haploid gametophyte. This kind is called diplontic.Haplo-diplontic-\xa0both phases are multicellular and exhibit an intermediate condition. They differ in their dominant phases. | |

Why gram negative do not take gram stain while gram positive takes it? |
| Answer» The\xa0Gram stain\xa0involves\xa0staining bacteria, fixing the color with a mordant, decolorizing the cells, and applying a counterstain.\xa0Both\xa0gram-positive and\xa0gram-negative cells have peptidoglycan in their cell walls, so initially,\xa0all bacteria stain\xa0violet.\xa0Gram staining involves three processes: staining with a water-soluble dye called crystal violet, decolorization, and counterstaining, usually with safanin. Due to differences in the thickness of a peptidoglycan layer in the cell membrane between Gram positive and Gram negative bacteria, Gram positive bacteria (with a thicker peptidoglycan layer) retain crystal violet stain during the decolorization process, while Gram negative bacteria lose the crystal violet stain and are instead stained by the safranin in the final staining process.\xa0 | |

State the location and functions of different types of meristems |
| Answer» Meristem : A meristem or meristematic tissues is a group of cells that are in a continuous state of division and thus continuously produce new cells. Location and function of meristems : On the basis of location and function, the meristems are of the following types:(1) Apical meristems : These are present at the apices of stems, roots and branches. The activity of the apices of stems, adds to the length of the plant or its part.(2) Intercalary meristems : These meristems are intercalated in between the permanent tissues. They may be present either at the base of the internode as in the stem of various grasses and wheat; or at the base of the leaf as in pinus; or at the base of a node as in mint. The activities of these meristems also add to the length of the plant or its organs.(3) Lateral meristems : These meristems are present along the side of the stem. These include cambium and cork cambium. The activity of lateral meristems adds to the thickness of the plant.

Nervous tissues and propeties |
| Answer» The nervous tissue has two outstanding properties : excitability and conductivity.(a) Excitability : It is the ability of the nerve cells and fibres to enter into an active state called the state of excitation in response to a stimulus. Excitation arises at the receptors on account of various stimuli such as light, temperature, chemical, electrical or pressure which constantly act on the organisms.(b) Conductivity : The excitation does not remain atthe site of its origin. It is transmitted along nerve fibres. The transmission of excitation in a particular direction is called conductivity | |
