What protists have a hard outer coating made of silica?
Mainly Diatoms
Are onecelled organisms with shells made of silica?
Yes, diatoms are one-celled organisms with shells made of silica. These shells are called frustules and are made up of two overlapping parts that fit together like a petri dish. Diatoms are a type of algae found in marine and freshwater habitats.
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.
Is a diatoms a carnivores?
Diatoms are microscopic plants (phytoplankton) found in oceans and lakes. Their cell wall is made of Silica which remain after the diatom dies. Diatoms are single celled, photosynthetic algae this means that they are producers!!
Are diatoms in glass?
No, diatoms are not found in glass. Diatoms are actually microscopic algae that are encased in a cell wall made of silica. Glass, on the other hand, is produced through melting sand and other materials at high temperatures to create a transparent, solid material.
What protists is closley related to chalk?
Coccolithophores are a group of single-celled algae that produce chalk-like plates made of calcium carbonate called coccoliths. They are closely related to chalk because their calcium carbonate exoskeletons can accumulate and form chalk-like deposits in the ocean.
What are large deposits of diatom remains called?
The cell wall of diatoms are very thick and remain long after the diatoms die. when the cell wall remains of many dead diatoms clump together, they form a crumbly, abrasive substance called diatomaceous earth or diatomite.============================================The rock type called Chalk is also made of diatom skeletons.
Why is Flamborough Head made from chalk?

Which type of sediment is made up mainly of the shells of diatoms and radiolarians?
We know that limestone is made up of those things, and some others. We also know that chalk, a kind of limestone, is composed mainly of tiny shells made of a mineral called calcite.
What does chalk contains?
Chalk is mainly made of Calcium Carbonate.

What is chalkdust?
dust from a chalk. Chalk is made from calcium carbonate, CaCO3.
What is the chalk made out of in baseball?

What class do diatoms belong in?
Diatoms belong to the class Bacillariophyceae, which is a class of algae characterized by their unique cell walls made of silica.
What is the meaning by Diatoms?
Diatoms are a form of algae found almost everywhere. Commonly diatoms refers to the silica exoskeleton left behind when the alga dies. White Cliffs of Dover made from billions of diatom skeletons.
