What is algae in biology?

Algae are photosynthesis-capable organisms that have chlorophyll and other photosynthetic pigments. But they lack the real roots, stalks, and leaves that vascular plants have. While others are multicellular, some of them are unicellular. Colonies may also form. Aquatic algae predominate. Some are terrestrial and can be discovered on damp rocks, trees, and soil. Symbioses between some algae species and other creatures are formed. Consider the symbiotic relationship between fungi and green (and occasionally blue-green) algae that results in lichens. The class of algae is polyphyletic.

This indicates that there is no common ancestor among the creatures in this group, nor are they necessarily closely related. While they lack other morpho anatomical traits found in vascular plants, they are eukaryotes capable of photosynthesis and have chlorophyll as their principal pigment. Phycology is the name given to the study of algae in science. Blue-green algae is mentioned in a few places. They are prokaryotes, nevertheless, and other sources do not classify them as algae because of this.

Q. What are algae give two example?

Ans. There are seven main types of algae, each with its own sizes, purposes, and colours. The various divisions consist of:

• Euglenophyta (Euglenoids)
• Chrysophyta (Golden-brown algae and Diatoms)
• Pyrrophyta (Fire algae) Chlorophyta (Green algae)
• Rhodophyta (Red algae)
• Paeophyta (Brown algae)
