Plants require the following raw material for photosynthesis: (i)CO2 is obtained from the atmosphere through stomata. (ii)Plant roots take up water from the soil.(iii)The raw material for photosynthesis is sunlight, water, and chlorophyll.(iv)Roots of plants can receive nutrients from the soil.
The differences between autotrophic nutrition and heterotrophic nutrition Autotrophic Nutrition Heterotrophic Nutrition Organism prepares its own food and is not dependent on any other organism. Raw material of Food preparation CO2, water, and sunlight. Chlorophyll ( green pigment ) is required for food preparation. Green plants and certain bacteria have autotrophic modes of nutrition. An …

The sustaining of life depends on processes such as digestion, respiration, excretion, circulation, and transportation.
Organisms utilise the outside raw material as a source of food and oxygen. The amount of raw resources needed depends on how complicated the organism is and where it is living.
It is possible to tell whether something is alive or dead by observing its walking, breathing, growth, and other apparent changes. To determine whether something is alive, the existence of the life process is a key requirement because some living objects will undergo changes that are invisible to the human eye.
Humans and other multicellular organisms need a lot of oxygen to diffuse fast into their enormous bodies in order to meet their oxygen needs. The slow process of diffusion means that it will take a long time for oxygen to reach all of the body\’s cells. Diffusion is too slow to supply enough oxygen to …
Because calcium (Ca) has a 20 atomic number(Z), the Electronics configuration is 1s2,2s2, 2p6,3s2,3p6,4s2. its electronic arrangement is 2, 8, 8, 2. Calcium, therefore, has two valence electrons. The element with atomic number 12 has an electrical configuration is 1s2,2s2, 2p6,3s2, Its electronic arrangement is 2,8.2. The element that most closely resembles calcium has two valence electrons.
The periodic table position of an atom is determined by the number of valence electrons, whereas the number of valence electrons is determined by the electronic configuration of the atom.
The atomic number of Nitrogen is 7, Electronic configuration of Nitrogen is 1s2,2s2,2p3 The atomic number of Phosphorus is 15 , Electronic configuration of Phosphorous is 1s2,2s2,2p6,3s2,3p3 On moving top to bottom a group in the periodic table, the number of shells increases. Due to this, valence electrons move away from the electrons and the …
