Diatoms are eukaryotes because they create photosynthesis in chloroplasts. ... Diatoms are producers within the food chain. A unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide) called a frustule. This makes the cell walls transparent.

Well, diatoms are a brown algae that typically appear in a reef tank that has just completed its cycle but they can also appear in an established reef tank. They can cover sand, rock, pumps, glass, you name it. Diatoms look ugly but in most cases they are harmless so the key is to not panic when they appear.

Diatoms (Chromalveolates supergroup, photosynthetic Stramenopiles, Bacillariophyta) are unicellular or colonial eukaryotic algae with unique cell walls composed of amorphous silica and consisting of two parts.

Many different organisms around the world, big and small, are made from eukaryotic cells. Any living thing that is made from more than one cell is made with eukaryotic cells. This includes all animals, plants, seaweed and fungi. Many microscopic organisms also have eukaryotic cells.

eukaryote. Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.

Cyanobacteria are sometimes considered algae, but they are actually bacteria (prokaryotic), where the term "algae" is now reserved for eukaryotic organisms. They also derive their energy through photosynthesis, but lack a nucleus or membrane bound organelles, like chloroplasts.
1098039
These are organisms with cells that contain a nucleus as well as membrane-bound organelles. The kingdoms most associated with Eukarya are the Plantae, Animalia, and Fungi kingdoms. Additionally, Kingdom Protista has had some of its organisms, such as amoebas and some seaweeds, classified as Eukarya.

Phytoplankton are microscopic marine algae. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water.

Eukaryotic Cell Definition. Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals. These organisms are grouped into the biological domain Eukaryota.
182361
Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

Red algae are protists or microscopic organisms in the phylum Rhodophyta, and range from simple one-celled organisms to complex, multi-celled organisms. ... Also surprisingly, they are not technically plants, although like plants they use chlorophyll for photosynthesis and they have plant-like cell walls.
1109354
Protozoa are single-celled eukaryotes (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy. They are often grouped in the kingdom Protista together with the plant-like algae and fungus-like water molds and slime molds.
47297
Photosynthetic algae known as phytoplankton are found in both marine and freshwater environments. Most marine phytoplankton are composed of diatoms and dinoflagellates. Most freshwater phytoplankton are composed of green algae and cyanobacteria.
1328949
The individual organisms constituting plankton are called plankters. ... Planktonic organisms include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit—for example—the pelagic zone of oceans, seas, or bodies of fresh water.
310238
Derived from the Greek words phyto (plant) and plankton (made to wander or drift), phytoplankton are microscopic organisms that live in watery environments, both salty and fresh. Some phytoplankton are bacteria, some are protists, and most are single-celled plants.

Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus (that holds DNA in the form of chromosomes) as well as membrane-bound organelles. Eukaryotic organisms may be multicellular or single-celled organisms. All animals are eukaryotes. Other eukaryotes include plants, fungi, and protists.
