Science Update

 We've been learning and exploring plants: what they need, what they are made of, and what they do. We learned about a plant's four needs: sunlight, water, carbon dioxide, and minerals/nutrients. We learned about photosynthesis which takes place in the chloroplasts; this is what makes the plant green... We also learned about different types of roots and their roles. We discovered that carrots, radishes, and beats are all taproots that hold extra "food" for its plant! We studied photosynthesis and learned that  leaves not only make sugar-food for the plant, but through their stomata (small openings) they absorb water and carbon dioxide, as well as expel water vapor and oxygen. This helps our environment. Did you know that not all plants have true roots? Check out this air plant below!
