This is the organelle in plants responsible for photosynthesis.
What is the chloroplasts?
500
When you draw a diagram of a food chain, the arrows represent this.
What is the flow of energy?
500
This is a small, undeveloped plant that is given a food source and can potentially grow under the right conditions.
