Does giant kelp have roots

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

Seaweed does not grow from seeds. Some seaweed have both male and female reproductive cells and can reproduce by division.

Answer 5

Yes, it's what keeps them on the ground and not just floating everywhere.

Answer 6

No, they have holdfasts which act like roots.

Answer 7

Giant kelp doesn't have roots because it is on top of the water.

Answer 8

no it produces spores :)
