its Hey now children, settle down. Today we're going to talk about life. There are six ways to know you're alive for sure:
1. Living things have cells.
2. They use stimuli to maintain a homeostasis.
3. They have DNA.
4. They reproduce.
I said no laughing!
5. They live, thrive and die.
6. They use energy.
Ayo, first things first:
There's three different types of living things on the Earth.
Ya heard?
There's organisms with one cell,
Whose life functions are performed by organelles.
And green plants use photosynthesis,
A chloroplast converts sunlight and lives with it.
And last are the animals, listen,
Cells, tissue, organ-to-organ system.
And they're unique; I can't lie, homes,
Only animal cells contain lysosomes.
But all cells contain ribosomes.
They make proteins, the building blocks, I suppose.
Yo, but don't get caught slipping
On the oils and the fats, a.k.a. the lipids.
Cells need fuel — they break carbohydrates
Into ATP, adenosine triphosphate.
Alright y'all! Cell theory has three parts:
1. All living things are composed of one or more cells.
2. The cell is the basic unit of life in all organisms.
3. All cells come from existing cells.
On top of that, they all have a cell membrane surrounding the cytoplasm, and most plants and bacterium have a cell wall.
Now let's travel to the center of the cell,
The nucleus, where nucleic acids are held.
They form DNA, the genetic code,
And multiply by mitosis if you let it go.
It's incredible, like the duty is
Of mitochondria — extract energy from nutrients.
And did I mention, the spot they make the lipids in,
Is the ER, or endoplasmic reticulum?
And the Golgi complex is next to it,
Delivering the products of the ER — excellent!
To hit the exit, you could use diffusion,
The membrane will pass in or out of solution.
Of all movement, the cell has control,
Disposing of waste in a vacuole.
And that can use active transport,
To either squeeze out or ingest something, so plan for it.
Alright y'all! Now who in here can spell flagella? And who knows where the word came from, "cell"? Anybody know that it's Latin? Cellula means "small room." Now before y'all go, let me remind you: Don't forget to respect the building block of life. Give it up for cells, y'all! Alright, class dismissed. Class dismissed. Get your flagella out of here.
