Why diatoms are different shapes and sizes?
There are many different species of diatoms, and the different species are different in shape and size.
Why do centric diatoms live in saltwater and pennate diatoms live in freshwater?
Centric diatoms have a spherical shape that helps them float and stay suspended in the water column, which is more common in saltwater environments with consistent water movement. Pennate diatoms have a more elongated shape that allows them to attach to surfaces in freshwater environments where there may be less water movement. This difference in shape relates to their respective preferences for saltwater and freshwater habitats.
Are diatoms prokaryotic?
Diatoms are eukaryotic, they are a major class of algae and the most common type of phytoplankton. They are unicellular yet exist in colonies in the shape of ribbons.
What's the difference between a pennate and a centric diatom?
Pennate diatoms have elongated, bilaterally symmetrical cells with a slit-like opening, while centric diatoms are circular or oval in shape with radial symmetry. Pennate diatoms are typically found in benthic habitats, while centric diatoms are more common in planktonic environments.
Which diatoms can move around the best?
pennate diatoms
Are diatoms classified as chrysophytes?
Yes, diatoms are classified within the division Chrysophyta, which includes golden-brown algae like diatoms.
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 do diatoms do?
Diatoms account for 23% of the primary productivity of the world, that's what they do!
Is diatoms a decomposer?
diatoms are producers, not decomposers. they are photosynthetic organisms
What is the phylum for diatoms?
The phylum for diatoms is Bacillariophyta. Diatoms are a type of algae that belong to this phylum and are characterized by their unique silica cell walls.
What mode of nutrition do diatoms have?
Most Diatoms are Photosynthetic but some have evolved to be heterotrophic
How big are diatoms?
Diatoms are microscopic. Diatoms range in size from about 2 microns to about 500 microns or equal to the width of a human hair.
