Any of various chiefly aquatic, eukaryotic, photosynthetic organisms, ranging in size from single-celled forms to the giant kelp. Algae were once considered to be plants but are now classified separately because they lack true roots, stems, leaves, and embryos.

Why do corral live in shallow water?

Coral live in shallow waters because they have a special relationship with algae. The algae live in shallow waters and carry on photosynthesis. Algae grow inside coral. They help the coral grow and build a skeleton.

How does algae take in oxygen?

Algae take in oxygen through a process called photosynthesis, where they use carbon dioxide and light energy to produce oxygen as a byproduct. Algae have special structures called chloroplasts that contain chlorophyll, the pigment responsible for capturing light energy and initiating this process.


How does algae gets its food?

Algae is a plant, and just like all plants algae makes sugar from sunlight. Rays of sunlight hit the plant and provide energy to water and carbon dioxide in a special compartment called a chloroplast. This energy turns water and carbon dioxide into sugar, which feeds the plant.


How do people use some algae products?

They can use it for food or if you want a seaweed mask u can use algae after it is processed.

What is the special features for red algae?

Red algae have unique characteristics such as the presence of phycoerythrin, a pigment that gives them their red color and allows them to photosynthesize in deep water where other algae cannot. They also have complex life cycles with alternation of generations, and their cell walls are made of cellulose and agar. Additionally, red algae are used in various industries for producing agar-agar, carrageenan, and as a food source in many Asian countries.


What are adaptions of algae?

The red, brown, yellow and green colors of algae help them blend in with the colors of the ocean floor,so they won't be found or eaten by their predators. Algae have special cells which make these colors appear so they can better use the light energy available to them while under water for photosynthesis. Another view: It is likely that the different pigments in algae allow them to compete for different wavelengths of light, either when crowded or when in different environments. Some algae have developed holdfasts to anchor them in place.


Which special characteristic is found in ceratium fusus but not in other algae?

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.


What are the three types of multicellular algae?

The three types of multicellular algae are red algae, brown algae, and green algae. These groups are classified based on their pigments, cell wall composition, and overall appearance. Each type of algae plays a unique role in aquatic ecosystems.


Is a algae a living thing or nonliving thing?

Yes! It is a plant-like protist. Algae are organisms similar to plants.They are photosynthetic autotrophs (i.e) they are living organisms which synthesize their own food with the help of solar energy which they capture through special pigments(mainly chlorophyll) present in them


Is algae a scaverger?
