1. Does kelp need fertilizer during its growth process?

Not necessary.

Seawater is rich in nitrogen, phosphorus, potassium, iodine and other substances, which are essential nutrients for the growth and development of kelp. In seawater, kelp grows like a nutrient solution, absorbing nutrients from seawater. The leaves of kelp are the proliferative part of kelp. They are not only the main body of kelp for photosynthesis, but also can absorb nutrients from seawater. The long leaves improve the efficiency of kelp in absorbing nutrients from seawater and photosynthesis. The flat stalk of kelp not only supports the leaves of kelp, but also can absorb nutrients from seawater and photosynthesize. The "roots" that play a fixing role and the part in contact with seawater can also absorb nutrients from seawater and photosynthesize. Like land plants, kelp can perform photosynthesis, but kelp does not have a system to transport water and nutrients to various parts of the algae, because its leaves, stalks, and "roots" can absorb nutrients from seawater and perform photosynthesis. The way kelp reproduces is also different from that of land plants. There are many bubble-like objects on the surface of the leaves of mature kelp. These bubbles are the spore groups of the kelp. The spore groups release spores, which scatter in the sea and gradually develop into male and female gametes. The released eggs and sperms then combine to germinate new kelp.
