Energy in Food (Photosynthesis)
Scientists are taking a leaf out of plants’ books and turning harmful gases such as carbon dioxide into useful chemicals!
Photosynthesis under a micropscope
Chloroplasts are organelles, or cell parts, are the parts responsible for trapping light energy to allow the cell to undergo photosynthesis! Chloroplasts are able to move around in the cell to a place where they can trap the most light.
During a starch test, iodine solution is added to a leaf. Iodine solution changes in colour , from yellowish-brown to dark blue when starch is present. This is an indication that photosynthesis has taken place as the leaf is able to make excess sugar which is converted to and stored as starch.
