Living cells with thin, uniform cellulose walls and intercellular spaces. They form the fundamental tissue system of plants. Specialized variants include Chlorenchyma (parenchyma with chloroplasts for photosynthesis) and Aerenchyma (aquatic plant parenchyma with large air cavities for buoyancy).
The "Powerhouse of the Cell." It is the site of oxidative phosphorylation and ATP generation. It features a double membrane with inner folds called cristae. Plastids: Found only in plant cells.
