Presentation on theme: "Cells  Organism: An individual living thing. It can be made up of one cell (unicellular) or up to billions of cells (multicellular).  Cell: “Little room”"— Presentation transcript:

1 Cells  Organism: An individual living thing. It can be made up of one cell (unicellular) or up to billions of cells (multicellular).  Cell: “Little room” that run on energy from the sun (sugars), they are alive because they take in nutrients, water and get rid of waste. They reproduce too.

2 Cell  Cells have structures (organelles) inside that help them carry out the characteristics of life:  Nucleus: “Brain/Library of the cell”, it has all of the directions to control the activities of the cell and reproduces.  Mitochondria: “Powerhouse of the cell” it produces energy from sugars  Endoplasmic Reticulum: Passageways through the cytoplasm of the cell to carry nutrients and wastes through the cell.

3 Cell  Ribosome: Protein factories of the cell (cell needs proteins to grow and repair cell parts)  Vacuoles: Storage tanks for the food, water or waste in the cell. Plant cell vacuoles are large, animal cells are small.  Lysosomes: “Clean up crew” for wastes in the cell. In animal cells.  Chloroplast: In plants only. It captures the sun’s energy and makes sugars through photosynthesis.  Cell wall: In plant cells only. It is the stiff outer layer that protects and supports the cell.  Cell Membrane: Outer covering of the cell that protects it and allows certain items to enter and exit.

4 Cell Drawing  Split your paper into 2 sections, 1 will be an animal cell, the other will be a plant cell.  Draw and color each and include the following cell structures and a definition of what they do for the cell: NucleusMitochondria Endoplasmic reticulumRibosome VacuoleLysosome Cell membraneCell wall Chloroplast **Use your green panda book on p. 73/74 to help you!**

5 Cell Poster Rubric  Draw and color a PLANT CELL and an ANIMAL CELL and include the following cell structures/organelles and a definition of what they do for the cell: NucleusMitochondria Endoplasmic reticulumRibosome VacuoleLysosome Cell membraneCell wall Chloroplast  7 organelles labeled and with definitions 14 pts  Colored, neat with a title6 pts

6 Cells: Elodea and Cheek Cells  Today we are going to look at:  A plant cell: Elodea  An animal cell: Cheek cell For both cells you will be making a wet mount slide using a coverslip: oads/procedures/slip.html
