Which of the following is true about Saprophytes?

botany know the plant world closely nutrition and its types types of nutrition in plants different modes of nutrition in plants

  1. They trap insects to meet their nitrogen requirement.

  2. They live on decaying organic matter.

  3. They share their food and shelter.

  4. Saprophytes contain chlorophyll.

Show answer
Correct Option: B
Explanation:
A saprophyte or saprotroph is an organism which gets its energy from dead and decaying organic matter. This may be decaying pieces of plants or animals. This means that saprophytes are heterotrophs. They are consumers in the food chain. This is the typical life-style of fungi.

So, the correct answer is 'They live on decaying organic matter.'.

  1. Bread pieces

  2. Pickles when kept in moist places

  3. On the ground after rains

  4. All of the above

Show answer
Correct Option: D
Explanation:

Saprophytes are organisms that can't make their own food. In order to survive, they feed on dead and decaying matter. Fungi and a few species of bacteria are saprophytes. They grow tubular structures, or hyphae, which are filaments that grow and branch into the dead matter, produce digestive enzymes and digest away the dead organism. In order for a saprotrophic organism to facilitate optimal growth and repair, favourable conditions and nutrients must be present.[4] Optimal conditions refer to several conditions which optimize the growth of saprotrophic organisms, such as;

  • Presence of water: 80–90% of the fungi is composed of water by mass, and requires excess water for absorption due to the evaporation of internally retent water.
  • In terms of nitrogen-rich sources, saprotrophs require combined protein for the creation of proteins, which is facilitated by the absorption of amino acids, and usually taken from the rich soil.
  •  Fungi, bread mould, some protists, and many bacteria are saprophytic in nutrition.

So, the correct answer is 'All of the above'.
