Question	Answer
Cell membrane	controls what goes in and out of the cell
cell wall	protects the cell and gives it shape it is non living and one component is cellulose. has pores that allow substances to pass through.
Endoplasmic Reticulum	allows certain substances to travel through these channels. -rough ER: synthesizes proteins -smooth ER: helps package macromolecules
Nucleus	-control centre of the cell -contains the blueprint that determines genetic make-up
nuclear membrane	-controls what goes in and out of the nucleus.
chromatin (chromosomes)	-long thin strings that are coiled (tangled) -contain the DNA
Nucleolus	-an area of chromatin that contains special RNA used to make ribosomes.
chloroplast	where photosynthesis takes place contains chlorophyll 6CO2 + 6H2O -> C6H12O6 + 6O2
mitochondrion	-powerhouse of the cell -provides all the energy (ATP) glucose + oxygen -> carbon dioxide + water
cytoplasm	-the jelly-like substance where the organelles -mostly water
golgi bodies	-completes the packaging of proteins and other macromolecules from the ER
Lysosomes	-where food and foreign substances are digested -when cell gets old or malfunctions it breaks down the entire cell
Ribosomes	Makes the proteins needed for all kinds of purposes Eg. Structure, hormones, enzymes
Vacuole	Where water is stored Also temporary storage of food or waste products
Centrioles	Found in pairs of micro tubules Important in cell division
