Algae Classification & Reproduction — NEET Biology
📚 Practice ConceptPlant kingdom includes algae, bryophytes, pteridophytes, gymnosperms and angiosperms. Algae are chlorophyll-bearing simple, thalloid, autotrophic and largely aquatic organisms. Depending on the type of pigment possessed and the type of stored food, algae are classified into three classes, namely Chlorophyceae, Phaeophyceae and Rhodophyceae. Algae usually reproduce vegetatively by fragmentation, asexually by formation of different types of spores and sexually by formation of gametes which may show isogamy, anisogamy or oogamy.
Assertion (A): Algae play a major role in global carbon dioxide fixation. Reason (R): Algae are chlorophyll-bearing, simple, thalloid, autotrophic and largely aquatic organisms.
