The cells of plants, algae, fungi, and most bacteria get their shape from the cell wall. It provides structural support and helps maintain the shape of the cell. In plants and algae, the cell wall is primarily composed of cellulose, while in fungi it is made of chitin.
Green, unicellular algae, some of which resemble a microscopic banana shape is a desmid.
An amoeba is a cell that can alter its shape by extending and retracting pseudopods. The term describes a characteristic but does provide a place for it in the taxonomy of organisms. Organisms as diverse as protozoa, algae, animals, and fungi all have members that qualify as Amoebas. SOME algae are amoebas but most amoebas are NOT algae.
Algae are photosynthetic organisms that contain chlorophyll for photosynthesis, while protozoa are single-celled organisms that typically feed on organic matter. Algae are usually green, brown, or red in color, while protozoa can vary in shape and size. Additionally, algae have a cell wall, while protozoa do not.
Pond silk is the common name of Spirogyra (algae) because it is very slimy in shape.
The green algae genus Volvox has many different forms, ranging from single-celled organisms to multicellular colonies. These colonies can have a spherical shape and contain hundreds to thousands of cells working together.
The theory of plants evolution that started from multicellular green algae is supported with evidence. First, the color and shape of small plants is similar with the green algae. Also, reproductive cycle , cell walls, the photosynthetic pigments are the same.
Pleco - Suckermouth catfish , Siamese Algae Eater, Albino Algae Eater , Ancistrus - Bristlenose pleco ,Oto Catfish , Plecostomus ( Very aggressive and go well with Oscar ) All algae eaters go well with Oscars.
The shapes of protists include bells, stars, snowflakes ,and pincusions they range in size from microscopic algae to giant seaweeds.
Seaweeds are classified into three major groups; the green algae, the brown algae, and the red algae. Placement of seaweed into one of these groups is based on the pigments and colouration existing in the plant. Other seaweed features that are used to classify algae include: cell wall composition, reproductive characteristics, and the chemical nature of the photosynthetic products. Plant structure, form and shape are additional characteristics used to classify seaweed.
Cell walls of plants and algae are made of cellulose. Cellulose is a structural polysaccharide that provides rigidity and support to the cell walls, allowing the cells to maintain their shape and protect the cell interior.
Ceratium fusus has a unique three-pronged or triradiate shape, which sets it apart from other algae. This characteristic allows it to easily move through the water column using its spines.
