What protozoa have shells made of silica?
Pretty sure its paramecium (phyla - ciliophora) Their shells are the most complex and have an outer layer called a pellicle that contains defense structures called trichocysts. (just reading it from my textbook)
Do protozoa have plastids?
Protozoa generally do not have plastids, as these organelles are primarily found in plants and some algae, where they are involved in photosynthesis. However, certain protozoan groups, such as euglenoids, contain plastid-like structures called chloroplasts that allow them to perform photosynthesis. These chloroplasts are derived from endosymbiotic algae. Overall, while most protozoa lack plastids, some specialized forms do possess them.
What are the characteristics that the Protozoa shares with most protists?
They are Unicellular.
Why is it more common to find protozoa in a hay infusion than bacteria?
The protozoa are larger and easier to see. There are a lot more bacteria because after all they are what the protozoa are feeding on but they at the very limit of resolution for most light microscopes. They are also less obvious because most don't move.
Which organelle cell is most directly involved in protein synthesis?
The ribosomes are the organelles most directly involved in protein synthesis, as they are the site where translation (the process of converting mRNA sequences into proteins) occurs. Ribosomes can be found both free-floating in the cytoplasm or attached to the endoplasmic reticulum.
Is macronucleus sexual or asexual?
The macronucleus is involved in asexual reproduction in ciliated protozoa, such as Paramecium. It controls most cellular functions, including growth and development, but is not directly involved in sexual processes.
Do protists have cell walls?
There is no longer a Kingdom of Protists. They are not a monophyletic group (clade). So, the answer is some do some don't. Algae (a type of photosynthetic protist) tend to have a cell wall. Protozoa (the animal like protists) do not. Most single cell protozoa have a pellicle to protect the cell.
Who was the most directly involved in the Independence of India?
Ghandi.
What protozoa have shells made of silica?

Is most of the worlds oyxgen produced by protozoa?
No , most of Protozoa are not photosynthetic hence can't produce O2 .
Are protozoa decomposer?
Only some protozoa are decomposers as giant Amoeba . Most protozoa are saprotrophic , some parasitic and some photosynthetic .
What cell organelle is most directly involved in the assembling of amino acids?
Ribosomes
What part of an atom is most directly involved in chemical bonding?
Electrons are the part of an atom that is most directly involved in chemical bonding. They are responsible for the formation of bonds between atoms by being shared, transferred, or attracted to other atoms.
Which process is most directly involved in the production of eggs cells by a female frogs?
meiosis
Which part of a typical land plant is most directly involved with the process of transpiration?
mitochondria
What are the characteristics that the Protozoa shares with most protists?
They are Unicellular.
How do you define the term protozoa?
The protozoa are one-celled animals and the smallest of all animals. Most of them can only be seen under a microscope.
