Controls all cell activities in the cell. Known as the "brain" of the cell
Nucleus
Transports proteins
Cell
what is the function of the diaphragm?
Controls/regulates the amount of light
Specialized structures that perform specific jobs inside a cell.
Organelles
Semi-permeable and controls what goes in or out of the cell. Known as the "security or gatekeeper" of the cell.
Cell Membrane
Contains digestive enzymes which break down worn-out cells and waste.
Lysosomes

What type of cell has a true nucleus and membrane bound organelles
Eukaryotes
Produces energy (ATP) through cellular respiration; also known as the powerhouse of the cell

Plants cells have chloroplast, cell wall, central vacuole
Animal cells have centrioles and lysosomes
plants perform photosynthesis and cellular respiration while animal cells can only do cellular respiration
Only present in plant cells and site of photosynthesis
Chloroplast
temporarily holds water and food. One large in plant cells and many little ones in animal cells
Vacuole
