Chief Deviation – Protozoa vs Algae

Protozoa and algae are 2 types of animals that belong to the kingdom Protista. Both protozoa and algae are eukaryotic organisms. Therefore, they consist of a membrane-leap nucleus. Both types can be unicellular. Only, algae can also bemulticellular. The chief divergence between protozoa and algae is that protozoa are heterotrophic, animate being-similar organisms whereas algae are autotrophic, institute-similar organisms. This means protozoa ingest organic molecules by phagocytosis while algae produce their ain food by photosynthesis.

What are Protozoa

Protozoa refer to single-celled animals that belong to the kingdom Protista. Though most protozoa are free-living, some of them infect college animals. Protozoa can obtain a diversity of shapes due to the absence of a cell wall. The gratuitous-living vegetative grade of protozoa is called the atropohozoite whereas the resting grade is called a cyst. The cyst of the protozoa is analogous to the spore of bacteria. Since protozoa are eukaryotic organisms, they contain a membrane-bound nucleus. Some protozoa may contain more than than i micronuclei. The excess water in the prison cell is removed by the contractile vacuoles. Food vacuoles can also be identified in protozoa. Amoeba, ciliates, flagellates, and sporozoans are examples of protozoa. A flagellate is shown in figure ane.

Effigy i: Flagellate

Protozoa areheterotrophic animals and obtain food past phagocytosis. The digestion occurs inside a food vacuole by the lysosomal enzymes. Flagella, cilia, and pseudopodia are used for the locomotion by protozoans.

What are Algae

Algae refer to a small, non-flowering, aquatic institute, which contains chlorophyll but lacks a true stem, root, leaves and a vascular system. Some algae are unicellular, and they are microscopic. They are chosen microalgae. This includes cyanobacteria (bluish-green algae) likewise as light-green, red, and brown algae. Other algae tin can be multicellular, which are known every bit macroalgae. Macroalgae are mainly seaweeds such every bit kelp, which abound well-nigh hundred feet in length.

Almost microalgae are autotrophic, and they produce their own food through photosynthesis. Some algae show a heterotrophic growth, by living in the night with the utilize of sugars. Another type of algae may employ both of the to a higher place growth modes, and this is called the mixotrophic growth. Algae produce 70% of the oxygen in the atmosphere through photosynthesis.

Similarities Betwixt Protozoa and Algae

• Both protozoa and algae belong to the kingdom Protista.
• Both protozoa and algae are eukaryotes.
• Both protozoa and algae contain a membrane-bound nucleus and organelles.
• Both protozoa and algae can be unicellular organisms.
• Both protozoa and algae can be establish in aquatic habitats.
• Both protozoa and algae can reproduce through mitotic division.
• Both protozoa and algae consist of flagella.
• Both protozoa and algae represent the foundation of food chains.

Difference Between Protozoa and Algae

Definition

Protozoa: Protozoa are single-celled animals that vest to the kingdom Protista.

Algae: Algae are small, non-flowering, aquatic plants containing chlorophyll only lack a true stalk, root, leaves and a vascular organization.

Related to

Protozoa: Protozoa are animal-like organisms.

Algae: Algae are plant-like organisms.

Methods of Obtaining Energy

Protozoa: Protozoa are heterotrophs.

Algae: Algae are autotrophs.

Significance

Protozoa: Protozoa ingest nutrient particles by phagocytosis.

Algae: Algae produce their own food by photosynthesis.

Chlorophyll

Protozoa: Protozoa do non incorporate chlorophyll.

Algae: Algae contain chlorophyll.

Jail cell Wall

Protozoa: Protozoa exercise not have a cell wall.

Algae: Algae have a cell wall fabricated upwards of cellulose.

Resting Unit

Protozoa: The resting unit of protozoa is the cyst.

Algae: The resting unit of algae is the spore.

Examples

Protozoa: Amoeba, Plasmodium, Euglena, Paramecium, Entamoeba histolytica, and Leishmania are the examples of protozoa.

Algae: Seaweeds, green algae, ruby-red algae, chocolate-brown algae, and cyanobacteria are examples of algae.

In Humans

Protozoa: Protozoa similarPlasmodium can cause diseases such as malaria in humans.

Algae: Algae may produce toxins, which are toxic to humans.

Importance

Protozoa: Protozoa serve as the foundation of most aquatic nutrient chains.

Algae: Algae produce 70% of the oxygen in the temper.

Decision

Protozoa and algae are 2 types of organisms that belong to the kingdom Protista. Protozoa are unicellular, animal-similar organisms. Algae are unicellular or multicellular plant-like organisms. Therefore, protozoa are heterotrophs while algae are autotrophs. The main difference between protozoa and algae is their mode of diet.
