Unformatted text preview: Intro to Cell Vocabulary Intro to Cell Vocabulary
Fancy Names For Simple Things Cells Cells Cells are the basic unit of all living things…if it is alive it has cells Two “Classes” of Cells Two “Classes” of Cells There are 2 classes of cells. There are only two differences between Plant & Animal cells…try to spot them by the end of the show
Plant cells Animal Cells There are only 2 classes of cells Cell Differentiation Cell Differentiation (plant/animal), but there are many kinds of cells in each class. Each kind of cell has a DIFFERENT job to do…it specializes.
I am a skin cell I’m a Prison Cell! I am a heart cell! When you hear the new When you hear the new vocabulary…just think of a Turtle The cell membrane holds the cell Cell Membrane Cell Membrane together and allows nutrients in the cell It’s just like a turtle’s skin The cell membrane is on the edge of a cell Cytoplasm Cytoplasm Cytoplasm is the watery gel (Jello!) inside a cell….it’s goop! It holds the ORGANelles Cytoplasm is like the turtles blood and other liquids Mitochondria Mitochondria Mitochondria is an ORGANelle that releases energy from food Mitochondria is like a turtle’s stomach Nucleus Nucleus The nucleus controls the cell The nucleus is like the turtle’s brain Chromosomes Chromosomes Chromosomes are inside the nucleus and are made of genes (DNA) Genes decide the cells traits and activities (heart cell, eye cell (color)) Nuclear Membrane Nuclear Membrane The nuclear membrane allows substances to pass in and out of the nucleus It surrounds the nucleus (the brain) like the turtle’s skull…protects it Vacuoles Vacuoles Vacuoles are spaces in the cytoplasm (gel) where food and chemicals are stored It’s like “fat” on a turtle
I am NOT fat…I’m just a little plump!! Cell Wall Cell Wall Cell Walls are only in plant cells They make the cell strong and rigid They are like a turtle’s shell (but only plants have them…that’s why grass stands straight up!) Chloroplasts Chloroplasts Chloroplasts are only in plant cells They contain chlorophyll, which helps make energy/food from sunlight Chlorophyll is green in color…so any plant that is green has chloroplasts
I’m green…do I have chloroplasts? What’s the Difference? What’s the Difference? So what are two things that Plant cells have that animal cells don’t? ?
Chloroplasts & Cell Walls What would happen if animals had What would happen if animals had Chloroplasts? Now, let’s review… Now, let’s review… Cell Membrane Chromosomes Mitochondria Plant/Animal Cell Wall Chloroplasts Nucleus Nuclear Membrane Cytoplasm Vacuoles Cell Differentiation Cells ...
