How does an amoeba get its nutrients?

Answer 1

An amoeba gets nutrients through the process of endocytosis, which is absorbing another organism into itself. This is done with a pseudopod, which is a temporary appendage used for absorbing another organism.

Answer 2

Heterotrophs are organisms which cannot make their own organic substances (eg carbohydrates, proteins etc) and so have to obtain them ready-made by eating food.

Autotrophs are organisms which can make their own organic substances from inorganic materials eg water and carbon dioxide. Plants are autotrophs.

Amoeba proteus is a free-living heterotroph, which feeds on other microscopic organisms such as ciliates and algae. These are ingested (taken into the cell) by pseudopodia, or "false feet". These are extensions of the cytoplasm which surround the prey and trap it in a tiny drop of water, forming a food vacuole. Enzymes are then added to the vaculoe to digestthe food. Useful substances are absorbed into the cell while indigestible materials are passed out.

Answer 3

I think this is what your asking for;

1. What is Chlamydomonas?

Chlamydomonas reinhardtii is a unicellular green alga.

Chlamydomonas swims with two flagella, and has chloroplasts for photosynthesis.

Chlamydomonas has nothing to do with Chlamydia, by the way.

Answer 4

Chlamydomonas is a single celled aquatic alga . It possess chloroplast and chlorophyll, it prepares its food by photosynthesis .

Answer 5

Amoeba obtains food by phagocytosis while Chlamydomonas is photsynthetic and prepares its own food from carbon dioxide and water .

Answer 6

Chlamydomonas obtains nutrients (energy) through the process of photosynthesis :)))))))
