Do protista have a cell wall?
Some protists have a cell wall made of various materials, such as cellulose, silica, or calcium carbonate. However, not all protists have a cell wall; some have cell membranes instead.
Do protists have a cell wall or cell membrane?
Protists can have either a cell wall, a cell membrane, or both. The presence of a cell wall in protists varies among different species and can be made of various materials such as cellulose, silica, or chitin. The cell membrane is common to all protists as it is essential for controlling the movement of molecules in and out of the cell.
What is scientific name of diatoms?
Diatoms are algae, diatoms are protists. Diatoms are placed in the division Bacilliariophyta, which is distinguished by the presence of an inorganic cell wall composed of hydrated silica.
Why are fungus like protists not members of the kingdom fungi?
plants contain cellulose in their cell wall while fungi contains chitin as a major component of its cell wall.Besides fungi are absorptive heterotrophs while plants are photosynthetic autotrophs.fungi lacks centrioles and contains chitin in its cell wall(as described earlier) but certain protists have centrioles and produce cellulose in their cell wall.some protists also contain some pigments like Chl.a Chl.b caroteins etc while fungi does not.Due to these reasons Fungi has separate kingdom.
How do protists exchange oxygen and carbon dioxide?
Protists exchange oxygen and carbon dioxide through simple diffusion across their cell membranes. These single-celled organisms rely on their large surface area-to-volume ratio to efficiently transport gases in and out of their cells.
What photosynthetic have a glassy two part cell wall made of silica?
Diatoms are photosynthetic organisms with a glassy two-part cell wall made of silica. These cell walls, called frustules, have intricate patterns and are responsible for the diverse shapes and sizes of diatoms.
What photosynthetic protists have a two part cell wall made of silica?
Diatoms are photosynthetic protists known for having a two-part cell wall made of silica. These intricate cell walls create unique geometric patterns and provide structural support to the organism. Diatoms play a significant role in marine ecosystems as primary producers.
Do protista have a cell wall?

The cell membrane is common to all protists as it is essential for controlling the movement of molecules in and out of the cell.
Do all protists have a cell walls?
No, not all protists have cell walls. Some protists have cell walls made of various materials like cellulose or silica, while others do not have cell walls at all. The presence or absence of a cell wall depends on the specific type of protist.
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.
What is scientific name of diatoms?
Diatoms are algae, diatoms are protists. Diatoms are placed in the division Bacilliariophyta, which is distinguished by the presence of an inorganic cell wall composed of hydrated silica.
What Phytoplankton with a glass like shell made of silica?
Diatoms are the phytoplankton with a glass-like shell made of silica. These minute algae have cell walls called frustules that are made of opaline silica, which gives them a distinctive glassy appearance. Diatoms are important primary producers in aquatic ecosystems and play a significant role in the food web.
What is the process whereby the mitochondria and chloroplasts of protists arise?
The process whereby mitochondria and chloroplasts in protists arise is through endosymbiosis, where an ancestral eukaryotic cell engulfed a prokaryotic cell (which evolved into a mitochondria or chloroplast) forming a symbiotic relationship. Over time, these organelles integrated into the host cell and developed a mutually beneficial relationship, providing energy and photosynthetic capabilities to the host cell.
How are euglenoids similar to animal-like protists?
They are both heterotrophs.
How many cells does a protists have?
Protists only have one cell.
What is a protists cell?
Eukaryotic. This means that it has advanced cell structure, including a nucleus. Protists were the first Eukaryotes.
