Yes they do. It is beneath the Si frustule and used in diatom defence against copepods. Check out Pohnert and Ianora's work on aldehyde production from polyunsaturated fatty acids in the lipid cell membrane.
Yes, they are because they have at least one nucleus
Yes, diatoms are classified within the division Chrysophyta, which includes golden-brown algae like diatoms.
Diatoms are primarily classified into two main groups: centric diatoms and pennate diatoms. Centric diatoms are radially symmetrical and typically found in aquatic environments, while pennate diatoms are bilaterally symmetrical and often inhabit benthic or sedimentary environments. Both types are characterized by their siliceous cell walls, known as frustules, which contribute to their ecological role in aquatic ecosystems.
i know some types of plankton eat diatoms and so do sponges,jellyfish and crabs and ther is still many more things that eat diatoms
Diatoms make silica shells called frustules. These frustules form intricate designs and patterns, which are unique to each species of diatom. The frustules function as protective outer coverings for the diatoms.
Yes, they are because they have at least one nucleus
pennate diatoms
Yes, diatoms are classified within the division Chrysophyta, which includes golden-brown algae like 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.
Organisms in the phylum Bacillariophyta are known as diatoms. They are single-celled algae characterized by their unique cell walls made of silica. Diatoms play a significant role in aquatic ecosystems as primary producers and are a major component of phytoplankton.
Diatoms account for 23% of the primary productivity of the world, that's what they do!
diatoms are producers, not decomposers. they are photosynthetic organisms
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.
Most Diatoms are Photosynthetic but some have evolved to be heterotrophic
Diatoms are microscopic. Diatoms range in size from about 2 microns to about 500 microns or equal to the width of a human hair.
Yes they are; diatoms are the main source of oxygen in the universe.
