Detailed explanation-1: -All algae contain chlorophyll. Some algae have pigments that mask the green chlorophyll. Algae exhibits different color variations because of the other photosynthetic pigments they contain.
Detailed explanation-2: -The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do n ot have roots, stems, or leaves. Some algae also differ from plants in being motile.
Detailed explanation-3: -Kelps and brown “algae" Phaeophytes, like most photosynthetic protists, have traditionally been classified as plants. However, phaeophytes are not closely related to land plants; their cells contain different pigments, such as chlorophyll c and fucoxanthin.
Detailed explanation-4: -Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15, 000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).
