Properties of cell organelles are not always found in the molecular constituents of cell organelles. Justify. |
Answer» Cell, the basic structural and functional unit is composed of many cell organelles, i.e., ER, Golgi apparatus, ribosomes, mitochondria, chlroplasts etc., each with a specific function. Each of these organcells are made up of various moleclules such as proteins, lipids, enzymes, metallic ions like `Mg^(2+),Ca^(2+),Mn^(2+),Na^(+)` etc, which helps in the functioning of cell organelles. e.g., molecular constituents like proteins `(60-70%),"lipids"(25-30%),"RNA"(5-7%)"NDA",Mn^(2+)"ETS,ATP"` synthase, etc. found in mitochondria function togather in a coordinated way to carry out cellular respiration and release energy, thus making it power house of cell. Thus, the molecular constituents of a cell organelle, forms the basis of its functioning irrespective of its individual molecular properties. |

Some of the properties of tissues are not the constituents of its cells. Give three exmples to support the statement. |
Answer» Cell in any multicellular organism is the smallest functional living entity. When many morphologically and functionally similar cells start functioning as a group. They form a tissue, which makes an organ performing a special function. e.g.,properties of tissues of stomach and intestine of digestive system is a co-ordinated function of different tissues to perform the functions of digention of food material. So, this property of digestion is the property of tissues and the organ, i.e., stomach, but not the property of individual cells which make the tissue and organ of the digestive system. Similarly, many neurons make nervous system and muscles make muscular system, but individual nerve cell/ muscle cell can perform the function of control, coordination and locomotion. |

Crabohydrates, the most abundant biomlecles on earth, are produced byA. all bacteria, fungi and algaeB. fungi, algae nd green plant cellsC. some bacteria, algae and green plant cellsD. viruses, fungi and bacteria |
Answer» Correct Answer - C (c) Some photosynthetic bacteria such as Rhodopseudomonas can prepare carbohydrates. But during thes type of food synthesis `O_(2)` is not evolved because , in this case hydrogen donor is other than `H_(2)O`. Algae (green and blue-green) and all green plant cells prepare their food (carbohydrate) through photosynthesis. Here, hydrogen ions are donated by water molecules by the process of photolysis of water, i.e. `O_(2)` is released during thes type of food synthesis. |
