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

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

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. I am a heart cell! I’m a Prison Cell!  I am a skin 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 It’s just like a turtle’s skin 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 like the turtles blood and other liquids

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

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

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 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

I am NOT fat…I’m just a little plump!! 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 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!)

I’m green…do I have 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?

Chloroplasts & Cell Walls 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 Chloroplasts?

Now, let’s review… Cell Membrane Cell Wall Chloroplasts Chromosomes Nucleus Nuclear Membrane Mitochondria Cytoplasm Vacuoles Plant/Animal Cell Differentiation Cells

Congratulations You now know all the vocabulary for cells

Using your Unit 1 textbook chapters, glossary, and/or notes, fill in definitions for the sheet you have been given. Unit 1 in your text is found in chapters 1-4. Try to rephrase the definitions in your own words as much as possible. Completed vocabulary sheets are due NEXT science class.
