Chloroplasts

Main Ideas:
-Green pigment (chlorophyll)

-Only present in plant cells

-Used in photosynthesis

Chloroplasts are plastids, organelles located in the cytoplasm, that contain chlorophyll. Chloroplasts play a main part in photosynthesis. They take sugar, sunlight, and water and turn into the plants food. 

Chloroplasts have two different membranes, the outer and the inner. Inside the inner membrane, there are tiny, green disks stacked like pancakes. Each individual disk is called a thylakoid. A stack of thylakoids is called a granum. They sit in a substance called stroma, it acts as a cushion to hold the 

granums. 

Before learning about chloroplasts this semester, I only knew that chloroplasts were a part of photosynthesis. I learned the different parts and how they play such an important part in photosynthesis. I like learning about this topic because its easy for me to remember. Also, I think its interesting to learn about how plants can make their own food and how not having one of the three components can effect the whole process. This process can be applied outside biology because if plants weren’t able to make their own food, they wouldn’t be able to make the oxygen we breathe and we would die.
