To classify protists in a sample of pond water, I would examine their morphology, such as shape, size, and movement patterns. Additionally, I would consider their mode of nutrition—whether they are autotrophic (like algae) or heterotrophic (like protozoa)—and their reproductive methods. Microscopic observation can also reveal characteristics like cilia, flagella, or pseudopodia, which aid in identification. Finally, I would assess their ecological roles and interactions within the pond ecosystem.
Yes it is a protist cos its plant-like and can only survive in water
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
Some can be found in pond water but not all.
Distilled water is almost devoid of free ions and molecules. So, when a living cell like a protist comes in contact with distilled water (which is hypotonic), large amounts of water enters the protist body, causing the cell to swell and burst, or suffer lysis.
fresh water
yes., yes it is.,
Yes!
"The cell membrane is a thin layer that surrounds and holds a cell together. This movement of water creates the problem. To understand how, consider a single-celled protist that lives in freshwater. The water inside the protist is mixed with many different chemicals. The water outside the protist contains few chemicals but few water molecules." - 9th Grade Biology Book
they live where there is an abundant source of water a.k.a moist areas
we can get clear water from a given sample of a muddy water by the method of decantation.
Contractile vacuoles in protists collect water and then expel it when they become full.
Stramenopiles or Heterokonts.
