What is holozoic mode of nutrition how Amoeba gets its food draw and explain |
| Answer» Amoeba\xa0follows holozoic mode of nutrition in which the solid food particles are ingested which are then acted upon by enzymes and digested.Steps of Nutrition in\xa0Amoeba:\tAmoeba engulfs food by temporary finger-like projections of its body surface called pseudopodia.\tWhen a pseudopodium fuses with the food particle, it forms a food vacuole.\tComplex substances are broken down into simple substances inside the food vacuole.

Explain opening and closing of stomatal pore |
| Answer» Mechanism of opening and closing of stomataOpening of stomata: Solutes from neighbouring epidermal and mesophyll cells enter the guard cells lowering its osmotic potential and water potential. This lowered water potential and osmotic potential will allow movement of water into guard cells from neighbouring cells. Guard cells become turgid due to water accumulation in them which results in the opening of the guard cells.\xa0Closing of stomata: As the somata open the solute concentration is reduced. This makes the water from the guard cells to move away into neighbouring cells. Now, guard cells becom flaccid with no water. They collapse against each other and result in the closing of stomata.\xa0 | |

What is double circulation? Is it important to make diagram |
| Answer» In double circulation, blood flows twice through the heart, during each cycle of passage through the body.Double circulation is important to keep the oxygenated and deoxygenated blood separate from each other in the body and prevent their mixing. Such separation allows a highly efficient supply of oxygen to the body.\xa0Another advantage of a double circulatory system is that blood can be pumped to the rest of the body at a higher pressure. | |

How is photosynthesis done |
|
Answer» Photosynthesis involves two types of reactions namely, light reactions and dark reactions.a) Light reactions: Light reactions are light dependent reactions. These reactions happen only in the presence of sunlight. The photosynthetic pigments trap the energy from the sunlight. PS-I and PS-II collectively bring in the cyclic photophosphorylation and non-cyclic photophosphorylation reactions. As a result of these reactions energy rich molecules like ATP and NADPH2\xa0are synthesised. Photolysis of water molecules results in the release of oxygen as a by-product. H2O → 2H+ + 2e- + ½O2b) Dark reactions: Dark reactions are independent of light. Energy rich molecules like ATP andNADPH2 are utilised in these reactions. Dark reactions involve Calvin cycle during which carbon dioxide is reduced to carbohydrate.C3 pathway is also known as Calvin cycle.C3 pathway involves set of carbon reactions which are catalysed by the enzyme Rubisco to synthesise 3 carbon compound, 3-phosphoglycerate from 5-carbon compound, Ribulose bisphosphate.\tRibulose bisphosphate is the primary acceptor of CO2.\tChloroplasts present are only of one type.\tAnatomy of leaves does not resemble Kranz anatomy.\tPhosphoglyceric acid is synthesised as the product.\tMesophyll cells exhibit Calvin cycle.\tPhotorespiration is observed.\tOptimum temperature required for photosynthesis is between 20 degree celsius\xa0to 25 degree celsius.\tThis cycle is less efficient in utilising CO2. Chlorophyll recives the light from the source which is sun and converts it into chemical energy and uses it in spliting of water moleculs into H(hydrogen) and O (oxygen ) it also is used in reduction oh carbondioxide to carbohydrates . The realease of energy is done in mitochondria . The conversion of light energy into chemical energy is done actually done in Grana which is present in chloroplast the because of this ATP and NADPH are formed . Then now we can say that the materials from atmosphere are taken up and are made them as stored forms of energy whis is called as photosynthesis. The bi products of photosynthesis are water and oxygen and the end product is starch. |

What is newland law |
| Answer» \tIn 1866 an English scientist John Newlands arranged the elements in the order of\tincreasing atomic masses starting from the hydrogen having lowest atomic mass to the 56th element named thorium having the highest atomic mass among the elements discovered at that time.\tIt was found that every eighth element possessed properties similar to that of the first. Sodium is the eighth element after Lithium possessing properties similar to one another. Similarly, beryllium and magnesium resemble each other.\tThis was comparable to octaves found in music and hence was called the ‘Law of Octaves’ or ‘Newlands’ Law of Octaves’.\xa0\tBut the Law of Octaves was applicable only up to calcium, after which every eighth element did not resembled the first element. | |
