Intro to Cell Vocabulary Fancy Names For Simple Things

Cells Cells are the basic unit of all living things…if it is alive it has cells Cells are the basic unit of all living things…if it is alive it has 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 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

Cell Differentiation There are only 2 classes of cells (plant/animal), but there are many kinds of cells in each class. Each kind of cell has a DIFFERENT job to do…it specializes. There are only 2 classes of cells (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 heart cell! I am a skin cell I’m a Prison Cell!

When you hear the new vocabulary…just think of a Turtle

Cell Membrane The cell membrane holds the cell together and allows nutrients in the cell The cell membrane holds the cell together and allows nutrients in the cell It’s just like a turtle’s skin It’s just like a turtle’s skin The cell membrane is on the edge of a cell The cell membrane is on the edge of a cell

Cytoplasm Cytoplasm is the watery gel (Jello!) inside a cell….it’s goop! It holds the ORGANelles 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 Cytoplasm is like the turtles blood and other liquids

Mitochondria Mitochondria is an ORGANelle that releases energy from food Mitochondria is an ORGANelle that releases energy from food Mitochondria is like a turtle’s stomach Mitochondria is like a turtle’s stomach

Nucleus The nucleus controls the cell The nucleus controls the cell The nucleus is like the turtle’s brain The nucleus is like the turtle’s brain

Chromosomes Chromosomes are inside the nucleus and are made of genes (DNA) Chromosomes are inside the nucleus and are made of genes (DNA) Genes decide the cells traits and activities (heart cell, eye cell (color)) Genes decide the cells traits and activities (heart cell, eye cell (color))

Nuclear Membrane The nuclear membrane allows substances to pass in and out of the nucleus 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 It surrounds the nucleus (the brain) like the turtle’s skull…protects it

Vacuoles Vacuoles are spaces in the cytoplasm (gel) where food and chemicals are stored Vacuoles are spaces in the cytoplasm (gel) where food and chemicals are stored It’s like “fat” on a turtle It’s like “fat” on a turtle I am NOT fat…I’m just a little plump!!

Cell Wall Cell Walls are only in plant cells Cell Walls are only in plant cells They make the cell strong and rigid 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!) They are like a turtle’s shell (but only plants have them…that’s why grass stands straight up!)

Chloroplasts Chloroplasts are only in plant cells Chloroplasts are only in plant cells They contain chlorophyll, which helps make energy/food from sunlight They contain chlorophyll, which helps make energy/food from sunlight Chlorophyll is green in color…so any plant that is green has chloroplasts Chlorophyll is green in color…so any plant that is green has chloroplasts I’m green…do I have chloroplasts?

What’s the Difference? So what are two things that Plant cells have that animal cells don’t? So what are two things that Plant cells have that animal cells don’t? ? Chloroplasts & Cell Walls

What would happen if animals had Chloroplasts?
