what are algae classified as?
603687
The algae have chlorophyll and can manufacture their own food through the process of photosynthesis. Recently they are classified in the kingdom of protiste, which comprise a variety of unicellular and some simple multinuclear and multicellular eukaryotic organisms that have cells with a membrane-bound nucleus.

Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch. ... They are all specialized water plants.

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.

Updated at 23 Jun, 2017 10:39 PM. Watermeal and duckweed are commonly confused for algae. In the picture below, there is actually NO algae. ... Algae is easy to distinguish from aquatic weeds because it is either stringy and mat-like (see below) or is microscopic and gives the water a green tint.
854233
 Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. ... The two main classes of phytoplankton are dinoflagellates and diatoms.

Algae are morphologically simple, chlorophyll-containing organisms that range from microscopic and unicellular (single-celled) to very large and multicellular. The algal body is relatively undifferentiated and there are no true roots or leaves.

The brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat.

Second, all brown algae are multicellular. There are no known species that exist as single cells or as colonies of cells, and the brown algae are the only major group of seaweeds that does not include such forms.

List algae and explain why they are important to coral reefs. Explain their roles. Brown Algae (temperate coastal ecosystems), Red Algae (coral reefs), Green Algae (food source), and Macro Algae (coral reefs).

Algae & Plants. Algae and plants are similar in that they can produce their own food from nutrients and sunlight by photosynthesis. The main difference between the two is in their complexity. Algae are simple organisms, sometimes unicellular, and even the largest types are relatively simple in structure.

Brown algae (Laminaria, Fucus) All Brown algae are multicellular and all go through an alternation of generation: diploid (2n) and haploid (n) phases alternate. The haploid and diploid life form look very different, they are heteromorph.

Alga is singular form and Algae is plural. ... Algae are the name given to a large group of oxygenic, phototrophic, eukaryotic microorganisms. Algae have a nucleus. The differences between plants and algae, many algal species are closely related to plants, but the algae are very diverse.

Seagrass can easily be confused with marine macroalgae, or seaweed, but there are many important differences between the two. While seagrasses are considered vascular plants and have roots, stems and leaves, seaweed are multi-cellular algae and have little or no vascular tissues.

Algae are plant-like organisms that can be either unicellular or multicellular, and derive energy via photosynthesis. Protozoa are unicellular organisms with complex cell structures; most are motile. Microscopic fungi include molds and yeasts.

Algae could be both unicellular and multi-cellular, whereas seaweeds are necessarily multi-cellular. All the seaweed species are autotrophic, whereas some algal species rely on other external food materials. ... Marine algae can distribute over shallow as well as deep waters, while seaweeds mostly inhabit shallow waters.
