Nutrition in Plants

This is the correct option, as this statement is false. The cell is enclosed by the cell membrane which surrounds a jelly-like substance known as cytoplasm, is the correct statement.

This is the correct option. Carbon dioxide, water, chlorophyll and sunlight are the necessary components for photosythesis. The green plants have chlorophyll in their leaves. The leaves use carbon dioxide and water to make food in the presence of sunlight. 

This is the correct option. An earthworm is not an autotrophic organism. It is rather a heterotrophic organism.

This is the correct option. The plants which trap insects and digest them by producing digestive juices are called insectivorous plants.

This is the correct option. Algae are autotrophic organisms that are capable of synthesing their own food.

This is the correct option. Sun is the ultimate source of energy for all living organisms. In plants, solar energy is captured by the leaves and stored in the form of food. 

This is the correct option, as the statement is false. Oxygen from air is taken in through the stomata present on the surface of the leaves, is a false statement. It is carbon dioxide, not oxygen that is taken in through the stomata present on the surface of the leaves.

This is the correct option. Alga provides food to the fungus, which it prepares by the process of photosynthesis. 

This is the correct option. Carbon, hydrogen and oxygen, all are the constituents of carbohydrates. These are used to synthesise other components of food such as proteins and fats.

This is the correct option. Nitrogen, oxygen, carbon and hydrogen - all are the composers of proteins. They all have a range of uses in the body such as serving as a source of energy, as substrates for tissue development as well as maintenance.

This is the correct option, as rhizobium bacteria do not live in the stem of legumes such as gram, peas and other pulses. They live in the roots of legumes and provide them with nitrogen. In return, the plants provide food and shelter to the bacteria.

This is the correct option. Iodine gives starch blue-black colour. Amylose in starch is responsible for the formation of a deep blue-black colour in the presence of iodine.

This is the correct option. Mistletoe is a partial parasite. This plant has green leaves and can synthesise its own food. But it recieves water and minerals from the host plant on which it grows.

This is the correct option. Autotrophs are the organisms capable of synthesising their own food from inorganic substances, using light or chemical energy. Heterotrophs are the organisms not capable of making their own food and depend on others for their food. Parasites are the organisms that derive nutrients from another organism. Hosts are the organisms that provide nutrients to another organism without being benefited.

This is the correct option. Cuscuta is a parasitic plant with yellow, slender and tubular stem; pitcher plant is a plant which traps and feeds on insects; starch is the food synthesised by the plants and rhizobium is a bacteria that converts atmospheric nitrogen into a soluble form.
