Cell Organelles structures specialized to perform distinct – processes within a cell Cells have an internal structure Cytoskeleton network of proteins, such as – microtubules and microfilaments inside a eukaryotic cell Microtubules long hollow tubes, give cell shape – and act as tracks for the movement of organelles Microfilaments tiny threads that enable to – move and divide Cytoplasm jellylike substance inside cells that – contains molecules, helps cells maintain shape Organelles involved in making and processing proteins Nucleus storehouse for genetic information (DNA) – Nuclear Envelope double membrane that encloses – the nucleus Endoplasmic reticulum (ER) interconnected network – of thin folded membranes that produce, process and distribute proteins smooth ER ribosomes – rough ER studded with ribosomes – Ribosomes tiny organelles that link amino acids – together to form proteins (site of protein synthesis) Apparatus closely layered stacks of – spaces that process, sort, packages, and deliver proteins Vesicles small organelle that contains and transports – materials within the cytoplasm Other Organelles Mitochondria Supply energy to the cell, bean shaped – and have two membranes, inner membrane has many folds that increases surface area
