Tag: different modes of nutrition in plants

A bacteria or fungi that lives within in a plant within the intercellular spaces, tissue cavities, or vascular bundles without harming the host is called as endophytes. They often benefit the host.

Parasitic plants are those which depend on other plants for their food either completely or incompletely. These plants produce a special organ called haustorium which produce adventitious roots to absorb food and nutrients.

So the correct option is D.

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.

The largest bloom is a parasitic plant, Rafflesia arnoldii which is found in the rainforests of Indonesia.
