 Boundary of the cell  Made of a phospholipid bilayer

 Controls center of the cell  Contains DNA  Surrounded by a double membrane  Usually the easiest organelle to see under a microscope  Usually one per cell  Contains ◦ Chromosomes ◦ Nucleolus

 Acts as skeleton and muscle  Provides shape and structure  Helps move organelles around the cell  Made of three types of filaments

 Connected to nuclear membrane  Highway of the cell  Rough ER: studded with ribosomes; it makes proteins  Smooth ER: no ribosomes; it makes lipids

 Site of protein synthesis  Found attached to rough ER or floating free in cytosol  Produced in a part of the nucleus called the nucleolus That looks familiar…what is a polypeptide?

 Looks like a stack of plates  Stores, modifies and packages proteins  Molecules transported to and from the Golgi by means of vesicles

 Garbage disposal of the cell  Contain digestive enzymes that break down wastes

 “Powerhouse of the cell”  Cellular respiration occurs here to release energy for the cell to use  Bound by a double membrane  Has its own strand of DNA

 Found only in plant cells  Contains the green pigment chlorophyll  Site of food (glucose) production  Bound by a double membrane

 Found in plant and bacterial cells  Rigid, protective barrier  Located outside of the cell membrane  Made of cellulose (fiber)

 Large central vacuole usually in plant cells  Many smaller vacuoles in animal cells  Storage container for water, food, enzymes, wastes, pigments, etc.

 Aids in cell division  Usually found only in animal cells  Made of microtubules

I went into a cell, and said "who makes 11. __________here?" And somebody responded "it's the 12.___________ my dear." I went into a cell, and was feeling pretty fine, ‘Til a 13._______engulfed me, and dissolved me in enzymes. I went into a cell, and was feeling pretty nimble, ‘Til a centriole lassoed me, tying me up in a spindle. I went into a 14._______ _______to see how trees get so tall, And all around the outside was a rigid 15._____________ I went into a plant cell, "why's it so green I asked?" "'Cause I make food from 16.____," said a green 17.________ I went into a plant cell to see how plant cells store 18._______ When a 19.________ informed me that he was the storage dude. So when you go inside a cell, remember what you see, There's over a 20.____________cells in both you and me. Just sing this song if you ever feel confusion, And remember active transport is the opposite of diffusion.

I went into a cell, to get out of the rain, And there was the gatekeeper, 1. the cell membrane. I went into a 2. cell, and what did I see? The 3.mitochondria, it's the energy factory. I went into a 4. cell, and said "who drives this bus?" And found myself talking to the boss, 5.the nucleus. I went into a cell, to recover from a spasm, And found myself swimming in some 6.clear cytoplasm. I went into the nucleus to ask how to get home, And got 7. genetic info, stored in a chromosome. I went into a 8.cell, and stretching o' so far, Was a thin and wavy network, it's called the 9. E.R. I went into a cell, trying not to be perplexed, By the packaging and sorting in the 10. Golgi complex. I went into a cell, and said "who makes 11. proteins here?" And somebody responded "it's the 12. ribosome, my dear." I went into a cell, and was feeling pretty fine, ‘Til a 13.lysosome engulfed me, and dissolved me in enzymes. I went into a cell, and was feeling pretty nimble, ‘Til a centriole lassoed me, tying me up in a spindle. I went into a 14.plant cell to see how trees get so tall, And all around the outside was a rigid 15.cell wall. I went into a plant cell, "why's it so green I asked?" "'Cause I make food from 16.sunlight," said a green 17.chloroplast. I went into a plant cell to see how plant cells store 18.food, When a 19.vacuole informed me that he was the storage dude. So when you go inside a cell, remember what you see, There's over a 20.trillion cells in both you and me. Just sing this song if you ever feel confusion, And remember active transport is the opposite of diffusion.
