Diatoms: A Complete Overview

The ability of diatoms to undergo photosynthesis makes them similar to plants, but plants and diatoms evolved this ability from separate ancestral lineages. One facet of diatom biology that is truly unique compared to other microorganisms is the diatom cell wall. Diatoms are given their shape and distinct glassy appearance because their ...

Diatomaceous Earth Fact Sheet

Diatomaceous earth is made from the fossilized remains of tiny, aquatic organisms called diatoms. Their skeletons are made of a natural substance called silica. Over a long period of time, diatoms accumulated in the sediment of rivers, streams, lakes, and oceans. Today, silica deposits are mined from these areas.

4.4: Diatoms

Ecology. In addition to morphology, diatoms can also be classified by where they occur. Free-floating diatoms are planktonic.Diatoms attached to other organisms (like giant kelp) are epiphytic.Benthic diatoms tend to dwell toward the bottom of a body of water.. Figure (PageIndex{6}): This image shows many diatoms, though they tend to be clumped on …

Diatoms Deciphered

As diatoms, plants, and animals evolved, each must have shed different genes from this common ancestor. As a result, diatoms were left with what looks like a mix of plant and animal DNA. The newly analyzed genome has also begun to shed light on how a diatom constructs its intricately patterned glass shell. So far, Rokhsar and his …
