Question

Quizplus · Accepted Answer

Holdfasts, gas-filled floats (known as bladders or pneumatocysts), and a thick, leathery surface are all characteristic features of brown algae. Red algae typically have holdfasts but lack gas-filled floats, and their surface is usually slimy or mucilaginous rather than leathery. Bryophytes are land plants that do not have holdfasts or gas-filled floats, and their surface is not leathery. Green algae can have holdfasts but do not typically have gas-filled floats or a leathery surface. Euglenoids are unicellular organisms and do not have holdfasts, gas-filled floats, or a leathery surface.
