Hydrophilic and hydrophobic structures
Found in cells of fungi and algae
Double layered membrane
I believe it is idiopathic.
The organelle you're looking for should be cholorplasts.
Chloroplasts are double membrane bound organelles, which is important for the process so photosynthesis. The outer membrane is smooth and gives the shape of the chloroplast, while the inner membrane forms sac that contains chlorophyll inside.
Chloroplasts exists in green plants that photosynthesize for energy, and they appear the most in mesohpyll cells, a type of cells in leaf.
Homeostasis it is an organism's ability to keep a constant internal environment.
