Make a comparison and write down ways in which plant cell are different from animals cells |
| Answer» Plant cells 1.most of the plants are stationary and hence, need less energy. Therefore, most of the tissues in plants are supportive in function and provide mechanical strength and are dead.Eg sclerenchyma , xylem tracheids and vessel coro etc.Animal tissues 1. Animals are locomotive and hence , need more energy. Therefore, animal tissues are made up of living cells.Eg nervous tissues/cells , muscular tissues/cells, connective tissue/cells etcPlant cells 2. Growth in plants is indefinite. Plants grow throughout their life with the help of certain tissues located in certain regions in the body. There are dividing and non-dividing tissues/cells in plants located at specific regionsAnimal cells 2. Growth in animals is almost definite. It is not confined to certain regions in the body. The animal organs grow more or less uniform. They do not possess specific regions of dividing or non-dividing tissues/cells.Plant cells 3. They are not much complicated.Animal cells 3. They are comparatively complicated.Hope it helps ?? if any doubts message in reply ? | |

Explain why particles of a colliders solution do not Settle Down When left undisturbed |
| Answer» We know that the particles in a colloid show random zigzag motion called brownian movements. These brownian movements counters the force of gravity acting on colloidal particles and helps in providing stability to colloidal particles by not allowing them to settle down. On the other hand, Particle size in a suspension is larger than those in a colloidal solution. Also molecular interaction in a suspension is not strong enough to keep the particles suspended and hence they settle down. | |

Explain three point of difference between striated muscle and smooth muscle |
| Answer» \tStriated Muscles or Skeletal muscles - These are called skeletal muscles as they are found attached to the bones and help in the body movements. The cells are cylindrical, unbranched, striated and multi nucleated. They are involuntary in nature.\tNon-Striated muscles or smooth muscles - The cells are spindle shaped, uni-nucleated, elongated and have no striations. They are found within the walls of elementary canal, bladder and blood vessels. They are involuntary in nature.\tCardiac Muscles - These are found exclusively in heart. They are cylindrical, non-tapering, branched with faint striations. They have one or two nuclei in each cell. They are involuntary. Their function is rhythmic contraction and relaxation throughout life. | |

What is endo osmosis |
|
Answer» Thanks If the surrounding medium of the cell has a higher water concentration than the outside solution, the cell will gain and will swell up water by osmosis. This process is also known as endosmosis The mass per unit volume is called density When there is a concentration is higher outside the cell then ,the cell will swell up and this process is called endosmosis. When there is more concentration outside the cell then inside ,this process is called endosmosis. As a result cell swell ups. |

What is blood cells and give (function, structure, location,uses |
| Answer» There are three types of blood cells. They are:(1) Red blood cells (Erythrocytes)\tMost abundant cells in the bloodRed Blood Cells (Erythrocytes)\tAccount for approximately 40 to 45 percent of the blood.\tBiconcave disc which is round and flat, sort of like a shallow bowl.\tDisk diameter of approximately 6.2-8.2 µm.\tThey have a thick rim and a thin sunken center.Functions\tTransport oxygen from the lungs to the cells of the body.\tPick up carbon dioxide from other tissues and unload it in the lungs.(2) White blood cells (Leukocytes)\tThey are the cells that make up the majority of the immune system.\tIt is the part of the body that protects itself against foreign substances and various types of infections.\tThey are made in the bone marrow from multi-potent cells called hematopoietic stem cells.\tThey exist in all parts of the body, including the connective tissue, lymph system, and the bloodstream.Functions\tKills bacteria through the process of phagocytosis.\tThey also release a burst of super oxides that have the ability to kill many bacteria at the same time.(3) Platelets (Thrombocytes)\tNucleus Absent.Platelets (Thrombocytes)\tDo not reproduce.\tSmall fragments of bone marrow cells.\t150,000–400,000 platelets in each microliter of human blood.Functions\tPlatelets are the parts of cells that the body uses for clotting.\tHelps to promote other blood clotting mechanisms. Example: Secrete procoagulants (clotting factors) to promote blood clotting.\tThey secrete vasoconstrictors which constrict blood vessels, causing vascular spasms in broken blood vessels.\tThey secrete chemicals that attract neutrophils and monocytes to sites of inflammation. | |

What is epithelial tissue and what is function? |
| Answer» Epithelialtissue is\xa0the covering or protective tissue in the animal body. Cells of epithelial tissues\xa0are tightly packed and form a continuous sheet. They have only a small amount of cementing material between them. They have\xa0very little intercellular spaces. Epithelium covers most organs and cavities within the body and also\xa0forms a barrier between different body systems to keep them separate. The skin, the lining of the mouth, the lining of blood vessels, lung alveoli and kidney tubules are all made of epithelial tissues. Epithelial tissues may be\xa0squamous (simple or startified), columnar, cuboidal or glandular. The permeability of the cells of various epithelia play an important role in regulating the exchange of materials between the body and the external environement. | |
