nucleus - controls and regulates the activities of the cell nucleolus - producing and assembling the cells ribosome nuclear membrane - separate the chromosomes from the rest of the cell chromosomes - carries genetic information from one generation to another ribosome - making proteins cytoplasm - responsible for holding the components of the cell and protects them from damage, stores the molecules required for cellular processes and is also responsible for giving the cell its shape cell membrane - provides protection for a cell, transport nutrients into the cell and also to transport toxic substances out of the cell mitochondria - membrane-bound cell organelles that generate most of the chemical energy needed to power the cells biochemical reactions Golgi complex - responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations vacuole - (animal cells - help sequester waste products ) ( plant cells - help maintain water balance) endoplasmic reticulum- produce proteins for the rest of the cell to function cell wall - surrounds the plasma membrane of the plant cells and provides tensile strength and protection against mechanical and osmotic stress chloroplast - allow plants to capture the energy of the sun in energy-rich molecules
