It surrounds the nucleus (the brain) like the turtle’s skull…protects it.The nuclear membrane allows substances to pass in and out of the nucleus.Genes decide the cells traits and activities (heart cell, eye cell - such as color).Chromosomes are inside the nucleus and are made of genes (DNA).It is similar to all the neuron pathways inside a turtle’s brain.It is responsible for making ribosomes.Inside the nucleus is another organelle called the nucleolus.The nucleus is like the turtle’s brain.It is the largest organelle in the cell and contains the cell’s DNA.Mitochondria is like a turtle’s stomach.Other cells need less energy to do their work and have less mitochondria. There are more mitochondria in cells that have to perform lots of work, for example - your leg muscle cells. Every type of cell has a different amount of mitochondria.Mitochondria is an ORGANelle that releases energy from food.Cytoplasm is like the turtles blood and other liquids.Cytoplasm is the watery gel (Jello!) inside a cell….it’s goop! It holds the ORGANelles.It’s just like a turtle’s skin - the cell membrane is on the edge of a cell. The cell membrane holds the cell together and allows nutrients into the cell.When you hear the new vocabulary, just think of a TURTLE! Restaurant Need 13 volunteers 6 to the back 7 up front I’m a Prison Cell! I am a heart cell! I am a skin cell Each kind of cell has a DIFFERENT job to do…it is specialized.Will only discuss 2 Plant & Animal cells - Plant cells Animal Cells There are 4 classes of eukaryotic cells.This is a prokaryotic cell Is a single celled organism that does not have a nucleus or membrane bound organelles. Need Volunteers Owner of a restaurant 1 waiter Need 6 guests Parts in common Cell Membrane Cytoplasm Organelles DNA The cell is the basic unit of all organisms.All organisms are made up of one or more cells.Cells are the basic unit of all living things.
