Hi, I'm Laura, and today I am going to be giving you a lesson on seaweed!!! LET'S GO!
Seaweed needs sunlight to make it's food. It uses chlorophyll to trap the little sunlight there is under water. It as well uses other pigments to use for food. The plant turns the light into a sugar substance for the plant called glucose. This is what the plant eats. The plant also absorbs the carbon dioxide in which we living organisms produce when we breathe out! The plants nee this for the photosynthesis to occur! Now, seaweed is different from most plants. Most plants, the photosynthesis occurs only in the leaves, but do to the seaweeds lack of a complex root system. The process of photosynthesis occurs as well in all their tissue. Isn't that interesting!!!?
On the board you see the equation for photosynthesis!
ME AGAIN! HERE WE ARE UNDERWATER WITH THE SEAWEED!!! THIS IS THE MARINE ECOSYSTEM!!!
That's our mini lesson on seaweed for today! I will se you guys next lesson!
