Add other organelles and structures: mitochondria (energy production), centrosomes (microtubule organization), chloroplasts (photosynthesis, in plant cells), vacuoles (storage, larger in plant cells), lysosomes (digestion), microtubules, microfilaments, intermediate filaments (cytoskeleton components), plasma membrane (cell boundary), peroxisomes (metabolism), ribosomes (protein synthesis), vesicles (transport), flagellum (movement, in some animal cells), microvilli (surface area increase, in some animal cells), plasmodesma (communication between plant cells), cell wall (structure, in plant cells), and ECM (extracellular matrix, in animal cells). Label each structure clearly.
