1 The Cell Part 3

2  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 vacuoles  Some animal cells have vacuoles Organelles - Vacuoles

3

4  Vacuoles would be the storage area (warehouse) of the factory  Paramecium have a contractile vacuole which can contract and pump water out of the cell to maintain a controlled internal environment (homeostasis) Organelles - Vacuoles

5

6  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 enclosure  The inner membrane is folded up inside the mitochondria Organelles - Mitochondria

7

8  In humans, nearly all of our mitochondria come from the cytoplasm from our mother’s egg cell  The mitochondria is like the power plant that supplies the factory with electricity Organelles - Mitochondria

9  Found in plants and a few other organisms  Capture energy from sunlight and convert it into chemical energy through the process of photosynthesis  Surrounded by 2 membranes (like mitochondria)  Contains chlorophyll – a green pigment  Chloroplasts are like solar power plants in a factory Organelles - Chloroplasts

10

11  Acts as the support structure and transportation system of the cell  The cytoskeleton is like the steel beams and concrete columns that hold up the factory building. Organelles – Cytoskeleton

12  Made up of protein filaments  Microfilaments – 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. Organelles - Cytoskeleton

13

14  In animal cells (not plant cells) centrioles are structures in the nucleus made of tubulin that help organize cell division  Microtubules also help build cilia and flagella which help with cell movement  In cilia, specifically, the microtubules are arranged in a 9+2 pattern Organelles - Cytoskeleton
