No, but they DO have a holdfast. Seaweed
is algae. Different from terrestrial plants, algae doesn't need a root system to absorb water and nutrients. In the absence of a root system, which provides a fixing point for plants, algae have "holdfasts." Holdfasts anchor seaweed to the sea floor.
No, in general seaweeds do not need to obtain moisture or nutrients form their substrate (which is what roots do for land plants). However, many types (not all) of seaweed need to anchor themselves to their substrate. Kelp is one of these seaweeds and to anchor itself to the seabed (usually rock) it uses a pad like structure called a "holdfast". A holdfast is a root-like structure but it is not a true root.
Seaweed does not have leaves. Because the entirety of the seaweed is in the water it takes up nutrients and other needed substances directly and has no need for leaves.
Seaweed does not grow from seeds. Some seaweed have both male and female reproductive cells and can reproduce by division.
Yes, it's what keeps them on the ground and not just floating everywhere.
No, they have holdfasts which act like roots.
Giant kelp doesn't have roots because it is on top of the water.
no it produces spores :)
idk sorry :( maybe cause its giant?
yes!
Giant kelp are neither animals nor plants. Giant kelp is in the Protista Kingdom.
Kelp is in the phylum Heterokontophyta, and the class Phaeophyceae.
Yes, giant kelp reproduce sexually. Giant kelp is a protist. Some kelp reproduce sexually while others reproduce asexually.
kelp does not eat, it is a plant. it photosynthesises
Giant kelp is a brown algae, some scientists believe it is a green algae but it is not.
Giant kelp is 100 feet but it can grow to 175 feet
Yes.
