Protists

haha

Protists are both mobile and stationary.

Properties of WBCs

Diapedesis:

WBCs can squeeze through the pores of blood vessels (even the

pore is much smaller than the cell size) by the process of

diapedesis.

Ameboid motion:

Once WBCs have entered the tissue spaces, they move through by

ameboid motion. They can move at least three times their own

length each minute.

Phagocytosis:

It's an essential process especially for the neutrophils and

monocytes. Selective structures can be ingested then digested via

this process. Phagocytes have proteolytic enzymes, lipases and

other agents (killer system) that kill the foreign materials.

Chemotaxis:

Different chemical substances can attract WBCs and make it move

toward the site of the chemicals. It depends on the concentration

gradient of these secreted substances.

Filamentous algae consists of long, thread-like strands made up of multiple cells joined end-to-end. These strands can be branched or unbranched, forming a mat-like structure. The cells of filamentous algae contain chlorophyll for photosynthesis and can reproduce by fragmentation or forming spores.

Diatomic means consisting of two atoms. In chemistry, diatomic molecules are molecules composed of only two atoms of the same or different chemical elements bonded together. Examples include oxygen (O2) and hydrogen (H2).

No. Tungsten is a metal and so exists as individual atoms.

There are 7 diatomic elements: Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, and Iodine. All can be found on the right side of the periodic table, with the exception of hydrogen, which is in the top left corner.

Amoebas like Entamoeba histolytica can cause amoebic dysentery, a type of severe diarrhea with blood and mucus. Acanthamoeba and Naegleria fowleri can cause rare but serious infections of the brain and central nervous system (acanthamoeba keratitis and primary amoebic meningoencephalitis, respectively).

Water is constantly coming down it's concentrations gradient and osmotically entering the paramecium's cell. The cell would soon burst if there were not a way to offload much of this water, so contractile vacuoles do this job for the paramecium.

All protists are eukaryotic organisms, meaning they have cells with a nucleus and membrane-bound organelles. They are primarily unicellular, although some can form multicellular structures. Protists exhibit diverse modes of nutrition, including photosynthesis, absorption, and ingestion, making them a highly varied group. Additionally, they can be found in a wide range of habitats, often in moist or aquatic environments.

Yes, Protozoa require moist environment; most species live world wide in ponds, lakes, streams, and oceans, where they are critical members of the plankton- free living, drifting organism that form the basis of aquatic food chains.

Its clitoris.

Amoeba ingests food by a process known as phagocytosis. The amoeba modifies its cytoskeleton to 'wrap around' the food particle with its membranes. The membrane then fuses, trapping the food particle in a vacuole inside the cell. The vacuole is then fused with a lysosome and the lysosomal enzymes will break down the food particle.

In a unicellular organism like Paramecium, food is stored and digested in a structure called a food vacuole. Once the food vacuole is formed, enzymes are released to break down the food particles for absorption and energy production.

diatoms are tinny substances found in water that are living

Amoebas primarily feed on bacteria, algae, and other small particles found in their environment. They engulf their food using pseudopods, which are extensions of their cell membrane that surround and engulf the food particles.

Its a type of algae .

PS: take note, diatom is also a type of algae. the major difference that you can observe between a diatom and a seaweed is their size. Diatom is a microalgae(microscopic in size) and seaweed, is a macroalgae(can be observed by the naked eye).

An amoeba gets energy in the same way that you do - from its food. An amoeba feeds by sending out 'bulges' of its cytoplasm, called pseudopodia, to surround a small food particle eg a smaller protozoan or an alga. The food, together with a small drop of the water is taken into the cell to become a food vacuole. Enzymes are then added to the food vacuole to digest the food. The soluble products of digestion are taken into the cytoplasm and used for respiration or growth. The release of energy from food is called respiration. Usually, the sugar called glucose is used by cells. Respiration usually involves 'burning' the food with oxygen. When this happens water and carbon dioxide are also produced: glucose + oxygen ---> water + carbon dioxide + ENERGY For a number of interesting articles about amoebae with photographs, go to: http://www.microscopy-uk.org.uk/full_menu.html Select Miscape article library, click on the Find icon and enter amoeba into the search box.

The only type of multicellular protists are plant-like seaweeds known as algae. There are three different types of algae that are differentiated by color. The brown algae is known as Phaeophyta, the red algae is known as Rhodophyta, and the green algae is known as Chlorophyta.

blepharisma are found it bacteria

An amoebae moving by using it's pseudopodia.

Plasmodium is a sporozoan that causes Malaria.

They are easily overlooked since they are transparent and often resemble decaying organic remains. Amoebas have lobe-shaped psuedopodia and are soil-dwelling fresh water or marine. The cytoplasm inside the cell is capable of changing into different states. It is able to turn from a fluid state plasmasol, to a more solid state plasmagel. A clever trick of the amoeba is they seem to use different engulfing tactics to suit various types of prey. They detect if a prey needs a fast approach (ciliates) or can be feasted on as a slow meal (immobile algae). Another amazing featture of the amoeba is when disturbed the amoeba proeus will change into a shape like a star. This allows it to free float in the water. These are just a few differences I could come up with maybe someone else can elaborate more:)

yes they do because they split up and make more of them.

food vacuole is a small cavity in the cytoplasm that temporarily store food.
