Answer:
Kelps are characterized by three main parts: blades, stipes, and holdfasts. The blades are similar to the leaves of land plants. ... Although kelps resemble land plants, they are uniquely adapted to life in cool, clear, moving water. They depend on moving water to provide a steady supply of nutrients for photosynthesis.
Step-by-step explanation:
Kelp is like a plant – it is photosynthetic and has structures that look like roots (the kelp holdfast), stems (the stipe) and leaves (blades)– but kelp and other algae belong to a separate kingdom of life from plants, called protists.
