Sometimes, unusual urine odor indicates a medical condition or disease, such as: 1  Bladder infection. 2  Cystitis (bladder inflammation) 3  Dehydration.

Photosynthesis occurs in eukaryotic cell structures called chloroplasts. A chloroplast is a type of plant cell organelle known as a plastid. Plastids assist in storing and harvesting needed substances for energy production. A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.
Problem 1 Tutorial: Chloroplast compartments. Chloroplasts are the organelles within plant and algal cells where photosynthesis occurs.The oxidation-reduction reactions involved in oxidation of water, reduction of NADP+, and synthesis of ATP via a chemiosmotic mechanism are located in the thylakoid membranes of the chloroplast.
