What features of chlorophytes (green algae), in contrast to phaeophytes (brown algae) and rhodophytes (red algae), are similar to plants? What features of chlorophytes (green algae), in contrast to phaeophytes (brown algae) and rhodophytes (red algae), are similar to plants? an embryonic stage protected from the environment an anatomy that includes a thallus (a structure similar to the stems/leaves/roots of plants) chloroplasts containing chlorophyll b multicellularity

Plants have chlorophylls a and b in their chloroplasts to serve as photosynthetic pigments along with other additional pigments. Chlorophytes, phaeophytes, and rhodophytes are the three major groups of algae classified on the basis of photosynthetic pigments, type of stored food and several other features such as cell wall, etc.

Brown algae, phaeophytes have chlorophyll a, c, and fucoxanthins are their major pigments while red algae, rhodophytes have chlorophyll a, d and phycoerythrin. None of these two groups have chlorophyll b. However, chlorophytes (commonly called green algae) have chlorophyll a and b in their chloroplast and therefore are similar to plants.
