What group does algae belong to?

kingdom Protista

Which is the fresh water algae?

What types of freshwater algae are there? The main groups of algae found in streams are the green algae (Chlorophyta), red algae (Rhodophyta), blue-green algae (Cyanobacteria) and diatoms (Bacillariophyta). Spirogyra is a common green alga. Under a microscope its chloroplasts are clearly seen as spirals.

What are the main groups of algae found in freshwater lakes?

There are three main groups of algae—the green algae (Chlorophyta), the golden brown algae (Chrysophyta) which also includes a large group called diatoms, and the blue-green algae (Cyanobacteria)—as well as several smaller groups (euglenoids, cryptomonads, and dinoflagellates).

Is algae a Protista or Plantae?

Plant-like protists are called algae (singular, alga). They are a large and diverse group. Some algae, the diatoms, are single-celled….Classification of Algae.

Type of Algae Origin of Chloroplast Type of Chloroplast
Green algae cyanobacteria two membranes, chlorophyll like a minority of cyanobacteria

What is the common name for euglena?

Euglena gracilis

Is euglena a bacteria?

Euglena, genus of more than 1,000 species of single-celled flagellated (i.e., having a whiplike appendage) microorganisms that feature both plant and animal characteristics. Found worldwide, Euglena live in fresh and brackish water rich in organic matter and can also be found in moist soils.

Why is euglena not a plant or animal?

From Wikipedia, Euglena is a genus of “unicellular flagellate protists.” The key to why they’re not considered plants or animals is in the word “unicellular,” which means the entire organism consists of one cell.

Is Chlamydomonas a plant or animal?

So, Chlamydomonas is a plant-animal, still related to the last common ancestor of the two kingdoms. The green yeast has been a denizen of the laboratory for decades. It is easy to grow in liquid cultures and has fascinating morphology and behaviors.

How do Euglenas move?

Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.

How do Euglenas eat?

Euglena eat green algae, amoebas, parameciums and rotifer. When an euglena is feeding, it surrounds the prey through a method called phagocytosis. This method allows the organism to surround its prey and absorb it. The euglena are normally found in the largest concentrations on water.

Do euglena push or pull themselves with their flagella?

All euglena have chloroplasts and can make their own food by photosynthesis. Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.

What is the movement of Volvox?

Volvox colonies move through their environment by the coordinated movements of their cells’ flagella. The dark circles on the colonies are immature daughter colonies.

Is Volvox a Mixotrophic?

But guess what? Volvox can also be a heterotroph, which means it consumes food (like you and me). It eats plants and algae in addition to the food it produces during photosynthesis.

What food does a Volvox eat?


How do Volvox colonies eat?

Colonies of Volvox consume the sun’s energy through the process of photosynthesis and turn it into sugar. The chemical reaction of photosynthesis is carbon dioxide plus water plus sunlight yields sugar, oxygen and water.

How do Desmids reproduce?

Reproduction. Desmids commonly reproduce by asexual fission, however, in adverse conditions, Desmidiales may reproduce sexually, through a process of conjugation, which are also found among the closely related Zygnematales.

Where does Volvox get energy?

Volvox. Obtain energy through photosynthesis (autotrophic). They contain chloroplasts.

What is an interesting fact about Volvox?

Reproduction: One of the interesting volvox facts is that the cell reproduces asexually as well as sexually. Volvox reproduction is a wonderful phenomenon to watch. Volvox colonies have spheres inside, which are actually ‘daughter’ colonies, known as gonads. It is a means of asexual reproduction.

How do amoeba get energy?

Cells, like humans, cannot generate energy without locating a source in their environment. This amoeba, a single-celled organism, acquires energy by engulfing nutrients in the form of a yeast cell (red). Through a process called phagocytosis, the amoeba encloses the yeast cell with its membrane and draws it inside.

What are two differences and similarities between a Volvox and amoeba?

Volvox is made up of one or more cells i.e, it is multicellular . Amoeba is made up of one cell i.e, unicellular . Volvox can be found in ponds, puddles, and bodies of still fresh water . Amoeba live in soil, ponds, lakes, forests and rivers.

What is the purpose of an amoeba?

Amoebae are also important for recycling nutrients in the soil. According to Maciver, when nutrients become available they are taken up by bacteria, that “effectively lock up all the nutrients in bacterial mass. ” When bacteria are consumed, nutrients are released back into the soil.

Does volvox have nucleus?

Nucleolus →contains the nucleus of the cell. Volvox: common single celled pond algae that consists of one or more colonies. Each cell uses its flagella simultaneously to move the colony.

Which protist uses cilia?

Amoeba and sarcodines are examples of protists that move by pseudopods. Some animal-like protists move by using cilia. Cilia are hair-like projections that move with a wave-like pattern. The cilia move like tiny oars to sweep food toward the organism or to move the organism through water.
