31.
Why seaweeds are not considered plants?
Lack vascular tissue such as true roots, stems and leaves
32.
Describe the structure and function of the following characteristics of seaweeds: a.
Blade – photosynthetic part of the seaweed b.

Holdfast – anchors to surface e.
Stipe – supports seaweed
33.
How do flowering plants (angiosperms) differ from seaweeds?
Flowering plants have vascular tissue and true roots, stems and leaves which take up nutrients through a vascular system and not simple diffusion.
