Question:

Read the following statement and find out the incorrect statement. 1. Algae usually reproduce vegetatively by fragmentation, asexually by formation of different types of spores and sexually by formation of gametes. 2. Algae are classified into three classes, pteridophytes into four classes and angiosperms into two classes. 3. Algae are chlorophyll bearing simple, thalloid, autotrophic and largely aquatic organisms. 4. The plant body of algae is more differentiated than that of bryophytes.
