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 That looks familiar…what is a polypeptidepolypeptide??

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._______________________

I went into a 2. _________ and what did I see?

The 3. __________________ it's the energy factory.

I went into a 4. _________ and said "who drives this bus?"

And found myself talking to the boss, the 5. _____________

I went into a cell, to recover from a spasm,

And found myself swimming in some clear 6._____________

I went into the nucleus to ask how to get home,

And got 7.__________ _________ stored in a chromosome.

I went into a 8._________ and stretching o' so far,

Was a thin and wavy network, it's called the 9._________

I went into a cell, trying not to be perplexed,

By the packaging and sorting in the 10.__________________

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.

And remember active transport is the opposite of diffusion.
