2 Organelles - Vacuoles Stores water, salts, proteins and carbohydrates Plants often have a single large vacuole filled with liquid – the pressure provided by this gives plants strength to support leaves, flowers, etc.Some single cell organisms have vacuolesSome animal cells have vacuoles
4 Organelles - VacuolesVacuoles would be the storage area (warehouse) of the factoryParamecium have a contractile vacuole which can contract and pump water out of the cell to maintain a controlled internal environment (homeostasis)
6 Organelles - Mitochondria Convert chemical energy stored in food into compounds that are easier for cells to use.Has an outer membrane and an inner membrane as an enclosureThe inner membrane is folded up inside the mitochondria
8 Organelles - Mitochondria In humans, nearly all of our mitochondria come from the cytoplasm from our mother’s egg cellThe mitochondria is like the power plant that supplies the factory with electricity
9 Organelles - Chloroplasts Found in plants and a few other organismsCapture energy from sunlight and convert it into chemical energy through the process of photosynthesisSurrounded by 2 membranes (like mitochondria)Contains chlorophyll – a green pigmentChloroplasts are like solar power plants in a factory
11 Organelles – Cytoskeleton Acts as the support structure and transportation system of the cellThe cytoskeleton is like the steel beams and concrete columns that hold up the factory building.
12 Organelles - Cytoskeleton Made up of protein filamentsMicrofilaments – threadlike structures made of a protein called actin. Provide a tough, flexible framework that supports the cell. (Amoebas assemble & disassemble microfilaments as a source of movement.)Microtubules – hollow structures made up of proteins called tubulins. They help maintain cell shape and help to separate chromosomes in cell division.
14 Organelles - Cytoskeleton In animal cells (not plant cells) centrioles are structures in the nucleus made of tubulin that help organize cell divisionMicrotubules also help build cilia and flagella which help with cell movementIn cilia, specifically, the microtubules are arranged in a 9+2 pattern
