Do algae have Pseudopodia?
For example, algae do not have roots, stems, or leaves. Some algae also differ from plants in being motile. They may move with pseudopods or flagella. Although not plants themselves, algae were probably the ancestors of plants.
What does cyanobacteria not have?
In plant cells, photosynthesis takes place in the chloroplast, small structures that contain chlorophyll and thylakoids. Cyanobacteria don’t have chloroplasts. Instead, the chlorophyll is stored in thylakoids in their cytoplasm.
How does a cyanobacteria move?
Cyanobacteria move by gliding, using mucilaginous excretions as propellant, or, in the case of planktonic genera, by altering buoyancy through gas vesicle formation and collapse. Cyanobacteria exhibit remarkable ecophysiological adaptations to global change.
Does cyanobacteria have a flagella?

Do cyanobacteria have chloroplasts?
Like all other prokaryotes, cyanobacteria lack a membrane-bound nucleus, mitochondria, Golgi apparatus, chloroplasts, and endoplasmic reticulum. All of the functions carried out in eukaryotes by these membrane-bound organelles are carried out in prokaryotes by the bacterial cell membrane.
Are cyanobacteria motile?
Cyanobacteria are a morphologically diverse group of phototrophic prokaryotes that are capable of a peculiar type of motility characterized as gliding. Gliding motility requires contact with a solid surface and occurs in a direction parallel to the long axis of the cell or filament.
Are cyanobacteria decomposers?
Green algae and cyanobacteria are found at the beginning of the food chain. They are known as primary producers because they make their own food.
What do chloroplasts have in common with cyanobacteria?
Additional and related shared traits in cyanobacteria and chloroplasts include the presence of photosynthetic pigments such as chlorophyll a and the presence of galactolipids in the membranes.
Do cyanobacteria have plastids?

Are Eubacteria autotrophs or heterotrophs?
Body Structure: Eubacteria are single-celled organisms. Food: Eubacteria are both auto- and heterotrophic. When they are autotrophic, they use both chemical synthesis and photosynthesis.
Why do cyanobacteria not have chloroplasts?
The reason for this is that they have chlorophylls which are dispersed in cytoplasm(not packed in chloroplast like photosynthetic eukaryotes). They carry out oxygenic photosynthesis i.e, they use water as an electron donor and generate oxygen during photosynthesis.
Do protists have peptidoglycan?
Protists have eukaryotic cell structure and are unicellular. Protists either lack cell wall or have cell wall made up of cellulose. Eukaryotes have cell wall made up of peptidoglycan or murein.
Are Eubacteria prokaryotes?
Eubacteria are prokaryotic microorganisms consisting of a single cell lacking a nucleus and containing DNA is a single circular chromosome.
Does cyanobacteria have a cell wall or plasma membrane?
Cyanobacteria are photosynthetic prokaryotes with three highly differentiated membrane systems: plasma membrane, outer membrane, and an internal system of thylakoid membranes. The presence of different membrane systems lends these cells a unique complexity among bacteria.
Does cyanobacteria undergo photosynthesis?
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.
How does cyanobacteria carry out photosynthesis?
Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed.
What is the shape of cyanobacteria?
Similar to other bacteria, cyanobacteria exist in a wide- ranging diversity of shapes and sizes. However, three general shapes are observed most frequently: spherical, rod and spiral. Bacteria can also grow as filaments of cells.
What is the function of gas vesicles in cyanobacteria?
Gas vesicles are spindle-shaped structures found in some planktonic bacteria that provides buoyancy to these cells by decreasing their overall cell density. Positive buoyancy is needed to keep the cells in the upper reaches of the water column, so that they can continue to perform photosynthesis.
Is zooplankton a decomposer?
Plankton also play a role at the end of the food web—as decomposers and detritivores.
Do cyanobacteria have colonies?
As the most common freshwater cyanobacterial genus, Microcystis is a unicellular microorganism, with high phenotypic plasticity, which forms colonies and blooms in lakes and reservoirs worldwide.
