Organismal Lab practical 1

The three characteristics green algae share with land plants are:

• the pigments chlorophyll A&B, and carotenoids

• Glucose as the carbohydrate storage material

• Cell walls made of cellulose

Characteristics of green algae

• domain eukarya, supergroup archaeplastida, kingdom plantae, phylum chlorophyta

• Can be unicellular, filamentous, colonial, and multicellular

• Can produce sexually and asexually
