Are blue green algae cells prokaryotic or eukaryotic?

Which kingdom does blue green algae belong to?

True bacteria

Cyanobacteria appear coloured because they contain the photosynthetic pigments chlorophyll (green) and photocyanin (blue). This means that they can produce their own food. Some cyanobacteria can also look red or pink due to the pigment phycoerythrin.

Cyanobacteria can be found in almost every terrestrial and aquatic habitat—oceans, fresh water, damp soil, temporarily moistened rocks in deserts, bare rock and soil, and even Antarctic rocks. They can occur as planktonic cells or form phototrophic biofilms. They are found in almost every endolithic ecosystem.

Algae use sunlight to make food and are eaten by microscopic animals (zooplankton). Small fish eat the zooplankton, and larger fish and other large animals eat the small fish. However, blue-green algae are often difficult to eat or are of poor nutritional value for zooplankton.

Blue-green algae, also known as Cyanobacteria, are a group of photosynthetic bacteria that many people refer to as “pond scum.” Blue-green algae are most often blue-green in color, but can also be blue, green, reddish-purple, or brown.

Cyanobacteria are clearly didermic (two membranes, inner and outer) bacteria, normally classified as Gram-negative bacteria. If your textbook says several times that they are Gram-positive, instead of a typo, you have a plain mistake. In conclusion, cyanobacteria are Gram-negative bacteria.

Molecular phylogeny (gene sequencing) and other characters show they belong to four kingdoms: Kingdom Plantae (e.g. chlorophytes and rhodophytes – green and red algae), the Kingdom Chromista (e.g. phaeophytes – brown algae – dinoflagellates, and diatoms), the Kingdom Protista (e.g. Euglenophytes), and the Kingdom

Red Slime Algae is actually a bacteria. Cyanobacteria, to be specific. Elevated waste levels including both phosphate and nitrate are the leading reason this slimy red film grows in your tank. Lack of proper water circulation and old light bulbs also cause excessive growth of Cyanobacteria.

When talking about algae as a vegan source of B12, it is usually in reference to blue-green algae. However, blue-green algae is not really algae. It is considered a type of bacteria because (unlike with alga, plants and animals), blue-green algae cells do NOT have a nucleus.

Classification. These are also referred to as blue-green algae. Though they are capable of conducting oxygen-producing photosynthesis and live in many of the same environments as eukaryotic algae, cyanobacteria are gram-negative bacteria, and therefore are prokaryotes.

Algae reproduce very quickly and need only sunlight (or another form of energy, like sugar), water, carbon dioxide and a few inorganic nutrients to grow.

Algae can either be unicellular and multi-cellular while plants are multi-cellular organisms. 2. Algae typically live underwater while plants thrive on land. They don’t have structures such as connective tissues, leaves, stems and roots unlike plants.

The majority of cyanobacteria are aerobic photoautotrophs. Their life processes require only water, carbon dioxide, inorganic substances and light. Photosynthesis is their principal mode of energy metabolism.

Algae are a diverse group of all photosynthetic organisms that are not plants. Algae are important in marine, freshwater, and some terrestrial ecosystems . Seaweeds are large marine algae. Algae may be unicellular, colonial, or multicellular.

Red, green, and brown algae have different types of pigments which give them their color. (Brown algae gets its color from the xanthophylls pigment fucoxanthin, red algae get their color from phycoerythrin, green is from chlorophyll.)

Algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.

The young of many aquatic animals such as frogs, fish and aquatic (water-dwelling) insects eat algae as their main source of food. Some adult fish and other creatures also eat algae. As for what algae “eats”—algae does not eat, because it is not an animal. Algae gets it energy from sunlight.

Edible seaweed, or sea vegetables, are algae that can be eaten and used in the preparation of food. They typically contain high amounts of fiber. They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae.

Cyanobacteria do not have organelles such as mitochondria, chloroplasts, endoplasmic reticulum or golgi apparatus that are found in eukaryotic cells. Ribosomes are the only organelles in the cytoplasm of cyanobacteria. These structures that contain RNA are responsible for protein synthesis.

Phytoplankton are tiny microscopic plants – algae – that form the base of the marine food chain. The most important living things on our green planet are single cell algae. And they are the most important because they produce oxygen, more oxygen than anything else does.

Organisms that rely on it need only light, carbon dioxide, and some inorganic nutrients to grow. There are exceptions, of course, such as carnivorous plants that live in low-nutrient habitats. And here’s a new one: microscopic algae that eat free-floating bacteria in the open ocean.
