1. Cell Structures Ms Vachon’s Biology Class

2. What are the two types of cells? Eukaryotic Eukaryotic Has a nucleus Has a nucleus Animal, plant, fungi, protists Animal, plant, fungi, protists Prokaryotic Prokaryotic No nucleus No nucleus bacterial cells bacterial cells Today, we look at eukaryotic cells Today, we look at eukaryotic cells

3. 1. Cytoplasm Cells are filled with this jello-like stuff Cells are filled with this jello-like stuff Picture a balloon filled with clear jello Picture a balloon filled with clear jello Cytoplasm is mostly water Cytoplasm is mostly water That’s why YOU are mostly That’s why YOU are mostly water water

4. 2. Cell Membrane The exterior of the cell The exterior of the cell Picture the balloon Picture the balloon Controls what moves in and out of the cell Controls what moves in and out of the cell What does a membrane look like? What does a membrane look like? What does a membrane look like? What does a membrane look like?

5. 3. Cell Wall Plant cells, fungal cells, plant-like protist cells and fungus- like protist cells Plant cells, fungal cells, plant-like protist cells and fungus- like protist cells Stronger then a cell membrane Stronger then a cell membrane Baracade to invaders Baracade to invaders *These cells still have a cell membrane inside the cell wall *These cells still have a cell membrane inside the cell wall

6. 4. Nucleolus and Ribosomes Nucleolus makes ribosomes Nucleolus makes ribosomes Ribosomes make pRotein Ribosomes make pRotein Who cares about protein? Who cares about protein? Who cares about protein? Who cares about protein?

7. 5. Mitochondria Makes energy from digested food Makes energy from digested food for the cell (and YOU) for the cell (and YOU) The “powerhouse” of the cell The “powerhouse” of the cell Mighty Mitochondria Mighty Mitochondria

8. 6.The Nucleus The “brain” of the cell Controls all functions of the cell Protects our DNA

9. 7.DNA DNA is the code for all life functions of the cell DNA is the code for all life functions of the cell DNA is wrapped around proteins to make chromatin DNA is wrapped around proteins to make chromatin Chromatin: DNA and protein “thread” Chromatin: DNA and protein “thread” Chromatin is further wraped to form chromosomes Chromatin is further wraped to form chromosomes DNA wrapping DNA wrapping DNA wrapping DNA wrapping

10. 8.Vacuole, Centriole, Chloroplast Vacuoles are “holes” or spaces for waste Vacuoles are “holes” or spaces for waste Centrioles are used in cell reproduction Centrioles are used in cell reproduction Chloroplasts (only in plant cells) contain chlorophyll Chloroplasts (only in plant cells) contain chlorophyll
