GENERAL HISTOLOGY

Detailed explanation-1: -Some sea weeds have a distinct, stem like structure to provide support is known as the stipe. Blades originate from stipe. Water and nutrients are picked up directly across the surface without the need of roots. Seaweeds consists of thallus, which is sometimes provided with leaf-like blades and a root like holdfast.

Detailed explanation-2: -Air bladders: a hollow, gas-filled structure organ which helps the seaweed float, found on the blade).

Detailed explanation-3: -Stipe: Stalk of a seaweed between holdfast and blade; this resembles a stem. Float: Air bladder that allows seaweeds to float closer to sunlight.

Detailed explanation-4: -The stalk or stem of seaweed is called a stipe. The function of the stipe is to support the rest of the plant. The structure of the stipe varies among seaweeds; they can be flexible, stiff, solid, gas-filled, very long (20 meters), short, or completely absent. The leaves of seaweeds are called blades.
