what are 2 ways protists get food?
156877
Protists get food in one of three ways. They may ingest, absorb, or make their own organic molecules. Ingestive protists ingest, or engulf, bacteria and other small particles. They extend their cell wall and cell membrane around the food item, forming a food vacuole.

Fungus-like protists are molds. Molds are absorptive feeders, found on decaying organic matter. They resemble fungi and reproduce with spores as fungi do. Examples of fungus-like protists include slime molds and water molds.

Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it. Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.

As a protozoan and a member of the kingdom Protista that has animal-like qualities, an amoeba has to find and eat its food (since it is unable to make its own food as plantlike Protists do). Of the many species of amoeba, some live in water and soil, while others are parasites and live inside plants or animals.

Fungus-like protists share many features with fungi. Like fungi, they are heterotrophs, meaning they must obtain food outside themselves. They also have cell walls and reproduce by forming spores, just like fungi. Fungus-like protists usually do not move, but a few develop movement at some point in their lives.

Cilia have important functions in the life of Paramecium, such as locomotion through the surrounding water and ingestion of food into the cytostome (see Wichterman, 1985). The cilia responsible for the ingestion of food are mainly localized in the gullet, which is a funnelshaped depression of the cell surface.

autotrophs make their own food-plants & algae. heterotrophs obtains energy from food it consumes.

Consumers and Decomposers. Recall that producers make their own food through photosynthesis. ... Fungi and many protists and bacteria are also consumers. But, whereas animals eat other organisms, fungi, protists, and bacteria "consume" organisms through different methods.

Plant-like protists are autotrophs. This means that they produce their own food. They perform photosynthesis to produce sugar by using carbon dioxide and water, and the energy from sunlight, just like plants. Unlike plants, however, plant-like protists do not have true stems, roots, or leaves.

The algae have chlorophyll and can manufacture their own food through the process of photosynthesis. Recently they are classified in the kingdom of protiste, which comprise a variety of unicellular and some simple multinuclear and multicellular eukaryotic organisms that have cells with a membrane-bound nucleus.

Amoeba Obtain Its Food By Amoeba envelops its food through the process of endocytosis or phagocytosis, where pseudopodia is created by flexibility of the plasma membrane. ... Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food-vacuole.

The main way animal-like protists differ from plant-like protists is in the way they get energy. Animal-like protists are heterotrophs. ... Plant-like protists, on the other hand, are autotrophs. They can make their own energy from the sun or other sources just as plants can.

Some protists are autotrophic, others are heterotrophic. Recall that autotrophs make their own food through photosynthesis or chemosynthesis (see the Photosynthesis concepts). Photoautotrophs include protists that have chloroplasts, such as Spirogyra. Heterotrophs get their energy by consuming other organisms.

Are cilia visible on living or prepared paramecium? Probably not. ... Avoid predation and to move to get food by pushing its contractile stalk to push the cell body as far as possible from the substrate and from others and then beats its cilia to capture food particles.

Biologists generally categorize protists according to their Mode of movement, or locomotion. All protists can travel through water by one of three methods: cilia, flagella, or pseudo/axopodia.
