Cell Organelles Think organs in a human body

Cytoplasm • Everything in the cell between the cell membrane and the nucleus • Cytosol-the liquid part of the cytoplasm

Ribosomes • • Located in cytoplasm (free) Located on the endoplasmic reticulum Where proteins are made Ribosomes

Cell Membrane • Controls what enters and leaves the cell • Selectively permeable--? ? ? • Plasma Membrane

Nucleus Control center of the cell; holds genetic Information (DNA) “The Brain of the Cell”

Chromosomes • A form of DNA in the nucleus • DNA

Nuclear Membrane • Surrounds the NUCLEUS • Has pores • Nuclear Envelope

Nucleolus • Inside the nucleus • Site of ribosome synthesis

Mitochondria (Mitochondrion) • “Powerhouse” site of cell respiration; provides energy (ATP) for cell Mitochondria

Smooth ER • No ribosomes; transportation within the cell; steroid synthesis • ER

Rough Endoplasmic Reticulum • Rough ER • Has ribosomes Transports proteins to other parts of the cell; “Highway System” of the cell

Golgi Apparatus -Stores, modifies, and packages proteins Golgi

Vacuole “Storage, ” stores water, waste, and food; very large in plants, smaller in animals Vacuole

Lysosomes • Contain digestive enzymes • “The stomach of the cell” • Lysosomes

Centrioles • Involved in cell division • Centrioles

Cell Wall (Plant Only) • Provides shape, structure, and support to plant cell—rigidity, made of cellulose

Chloroplast (Plant Only) • Organelle that makes food for the plant (photosynthesis) • Tour of a Plant Cell
