Question

describe different modes of nutrition in protista

Answer 1

The cells of protists need to perform all of the functions that other cells do, such as grow and reproduce, maintain homeostasis, and obtain energy. They also need to obtain "food" to provide the energy to perform these functions.

Recall that protists can be plant-like, fungi-like, or animal-like. That means that protists can obtain food like plants, fungi, or animalsdo. There are many plant-like protists, such as algae, that get their energy from sunlight through photosynthesis. Some of the fungus-like protists, such as the slime molds (Figure below), decompose decaying matter. The animal-like protists must "eat" or ingest food.

Some animal-like protists use their "tails" to eat. These protists are called filter-feeders. They acquire nutrients by constantly whipping their tails, called flagellum, back and forth. The whipping of the flagellum creates a current that brings food into the protist.

Other animal-like protists must "swallow" their food through a process called endocytosis. Endocytosis happens when a cell takes in substances through its membrane.

Answer 2

Answer:

Three modes of nutrition are found in protista kingdom-

1. Autotrophic = Some protists are photosynthetic like algae. They prepare their own food by inorganic raw materials.

2. Heterotrophic = They obtaine their food by eating other organisms or decaying organic matter in the environment.

3. Mixotrophic = Some protists have both mode of nutrition i.e. autotrophic and heterotrophic.

Example is prymnesium parvium.
