Protists

Amoebas feed by engulfing food particles through a process called phagocytosis. They extend their pseudopods around the food particle, forming a food vacuole that contains the particle. Digestive enzymes are then secreted into the food vacuole to break down the food for absorption.

Diatoms and dinoflagellates are primary producers in marine ecosystems, playing a critical role in the food web by providing food for various organisms such as zooplankton, shellfish, and small fish. Their depletion could disrupt the entire marine ecosystem, leading to cascading effects on higher trophic levels. Additionally, these organisms are involved in the production of oxygen and carbon sequestration, affecting the global biogeochemical cycles.

Amoeba are protozoans. They eat algae and other protozoans. Protozoans are eaten by zooplankton in the marine environment.

yahoo answers is usually where i always go for first choice. but for background information use buzzle or ask.com it usually helps. Yes i know this the paramecium is a difficult topic.. but thats ok.

Amoeba obtain its food by the process of endocytosis. It is due to the flexibility of cell membrane as it enables the cell to engulf food and other materials from its external environment. There are four ways in which an amoeba can ingest solid food:

1. Circumvalletion-when the prey is active and motile, e.g. Any smaller protist

2. Circumfluence- when the particle is sessile e.g. Unicellular algae

3. Import- then particle comes into contact with the amoeba and then sinks into it just like in quicksand.

4. Invagination- the amoeba does'nt use it's pseudopodia here, instead it pinches off a portion of it membrane to form a tube like structure which, along with the particle makes a food vacuole.

No, they don't live in soup, dribble or anything like that. It might strike you with awe that amoebae live in homes they build themselves. They can have shapes like a globe, cigar-shape, cube and so on, and none is bigger than a full-stop - all without a brain.

They may be brainless, but you cannot call an amoeba 'simple'.

A paramecium is not autotrophic. A paramecium is heterotrophic. The paramecium are single-celled organisms that are found in marine environments and stagnant ponds.

Amoebas move by extending their cell membrane out in the direction they want to go, forming temporary protrusions called pseudopods. They then flow their cytoplasm into the pseudopods, allowing them to move in a process known as amoeboid movement.

Not to us. They are very small fossilized particles that to our skin feels like talcum powder. To smaller creatures, they are sharp as glass. Diatomaceous earth is a product sold at most garden centers. These fossilized particles are used to keep smaller pests like ants and slugs from the stalks of plants. These small diatoms poke into the segmented parts of ants and the soft skin of slugs and snails, becoming an annoyance, and they leave.

All protists belong to the taxonomic domain of Eukarya, members of which are characterised by having cells with nuclei. Eukarya covers all organisms in the Kingdom Protista, as well as the Kingdoms Plantae, Fungi and Animalia.

Any type of skeleton requires multiple cells to harden and support the animal. An amoeba is an invertebrate and a one-celled creature that barely has a cell wall. It surrounds its food with its body and then digests it. It has neither endo- or exoskeleton.

Simple diffusion has limitations in organisms like amoebas because it is reliant on the concentration gradient and does not require energy input, limiting the movement of substances against a gradient or in areas of low concentration. Amoebas may not efficiently absorb necessary nutrients or expel waste in areas of low concentration due to the passive nature of simple diffusion, which affects their overall metabolic processes and growth.

one example of protist autotroph is euglana plasamamembran diagram with a energy corce one example of protist autotroph is euglana plasamamembran diagram with a energy corce A Bromeliad is another one!!

All green plants are autotrophs, using sunlight to convert carbon dioxide and water into sugars by photosynthesis.

I love cats and they love me.

Paramecium are commonly used in scientific research as model organisms to study cell structure, physiology, and behavior. They are also used in ecological studies to indicate water quality and in educational settings as a model organism for teaching basic biological concepts. Additionally, some cultures consume paramecium as a food source, although this is less common.

The presence of hydrolytic enzymes is most closely associated with the cell organelles known as lysosomes. Lysosomes are membrane-bound organelles that contain various hydrolytic enzymes capable of breaking down molecules such as proteins, nucleic acids, lipids, and carbohydrates. This process helps in recycling cellular components and breaking down foreign substances or damaged organelles.

Amoeba is considered an organism because it is a single-celled microorganism that exhibits all the characteristics of life, such as feeding, growing, and reproducing. It can carry out essential life processes independently.

Plant-like protists, such as algae, can affect other living things by producing oxygen through photosynthesis, which is essential for the survival of many organisms. Additionally, some plant-like protists can serve as food sources for other organisms in aquatic ecosystems, forming the base of the food chain. However, excessive growth of plant-like protists, such as harmful algal blooms, can have negative effects on other organisms by depleting oxygen and producing toxins.

A paramecium eats by using its cilia to sweep food particles into its oral groove. The food particles are then engulfed by the paramecium and enclosed in a food vacuole. Digestive enzymes are then secreted into the food vacuole to break down the food particles for absorption.

Amoebas take in oxygen through a process called diffusion, where oxygen molecules move into the cell across its cell membrane. The oxygen then reacts with other molecules in the cell to produce energy for the amoeba to survive and carry out its functions.

The cell walls of diatoms are composed of silica, in the form of hydrated silicon dioxide (SiO2). This silica helps provide structure and rigidity to the cell walls, allowing diatoms to maintain their unique shapes and withstand environmental pressures.

Boil ¼ cup of water. Add one teaspoon of gelatin and one teaspoon of

sugar. Stir for one minute until everything is dissolved.

2. Cool the solution for ten minutes.

3. Fill a petri dish to a little below the top edge.

4. Close the petri dish by putting on the cover immediately. Let the

covered petri dish stand for at least four hours. Don't touch the

growth medium or you'll add your own germs!

This recipe will fill two, small petri dishes. If you and your class plan to fill

more petri dishes, make more germ food by increasing the amount of your

ingredients proportionally.

Neon is an inert, or noble gas. As such, it isn't interested in combining with any other atoms, nor is it interested in hanging out with a like buddy in a diatomic molecule. Remember that the diatomic molecules are the elements that end in -gen (including the halogens). So no, neon is just a singular, fully occupied outer shell atom...just content to be by itself.

Paramecia and amoebas belong to the Kingdom Protista. This kingdom includes diverse organisms that are mostly unicellular and have distinct characteristics from plants, animals, and fungi.
