In other words, most algae are autotrophs or more specifically, photoautotrophs (reflecting their use of light energy to generate nutrients). However, there exist certain algal species that need to obtain their nutrition solely from outside sources; that is, they are heterotrophic.

Microorganisms are divided into seven types: bacteria, archaea, protozoa, algae, fungi, viruses, and multicellular animal parasites ( helminths ). Each type has a characteristic cellular composition, morphology, mean of locomotion, and reproduction.

The five types of living micro-organisms are bacteria, viruses, fungi, algae and protozoa.

Etymologically, algae is the plural of alga, but algae is sometimes used as an uncountable noun with singular verb agreement (similar to the usage of the word seaweed), or as a count noun to refer to a type of algae. The plural form algaes may be considered nonstandard.

Dinoflagellates can be either heterotrophic, autotrophic, parasitic, or symbiotic. Many are autotrophic, photosynthetic protists and primary producers.

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.

Algae are sometimes considered protists, while other times they are classified as plants or choromists. Phytoplankton are made up of single-celled algae and cyanobacteria. As algae can be single-celled, filamentous (string-like) or plant-like, they are often difficult to classify.

['Bryophytes, an informal group that taxonomists now treat as three separate land-plant Divisions, namely: Bryophyta (mosses), Marchantiophyta (liverworts), and Anthocerotophyta (hornworts). ... ', 'Algae - especially the green algae.']

While algae contain chlorophyll (like plants), they do not have these specialized structures 8. Algae are sometimes considered protists, while other times they are classified as plants or choromists. Phytoplankton are made up of single-celled algae and cyanobacteria.

Macro algae are multicellular marine algae which form a real plant. ... Micro algae are different. They are one cell algae. Spirulina, Chlorella or also blue green algae are very popular in this variety.

Photosynthetic Algae Algae are eukaryotic organisms that have characteristics of both plants and animals. Like animals, algae are capable of feeding on organic material in their environment.

Seaweeds are algae. Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.

Green algae have chloroplasts that contain chlorophyll a and b, giving them a bright green color, as well as the accessory pigments beta carotene (red-orange) and xanthophylls (yellow) in stacked thylakoids. The cell walls of green algae usually contain cellulose, and they store carbohydrate in the form of starch.
1283873
Red algae contain chlorophyll a and d while green algae contain chlorophyll a and b. Red algae appear red in colour due to pigment r-phycoerythrin while green algae appear green in colour due to chlorophyll b. The food reserve in red algae is floridean starch while the food reserve in green algae is starch.

Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Algae can be multicellular or unicellular. Unicellular algae occur most frequently in water, especially in plankton.
