BIOLOGY IS THE STUDY OF LIFE

BIOLOGY IS THE STUDY OF LIFE

Biology is the study of lifeWith bacteria, protists, fungi, plants, and

animals.The cell is the basic unit of life

For bacteria, protists, fungi, plants and animals.

They reproduce and organize, use energy and grow, react to stimuli.

Oh, Oh, the autotrophs capture the light and convert it into food supplies for everyone.

So sing the kingdoms with me one more time, that’s bacteria, protists, fungi, plants and animals.

Prokaryotes are the simplest cells.A nucleus they do not possess.Eukaryotes have a nucleus bound in a membrane making them more complex.

Eukaryotes have organelles.Prokaryotes are little cells.Bacteria is all they are those little cells go very far.

Oh, Oh, the autotrophs capture the light and convert it into food supplies for everyone.

ORGANIC COMPOUNDS

• Tune of I’ve Been Working on the Railroad

ORGANIC COMPOUNDS

Organic compounds made of carboncome from living cells.

Their monomers are linked togetherto make them function well.

Proteins are the body builders. Their enzymes catalyze.

Carbohydrates give the energy to keep our cells alive.

Nucleic acids have the code, genetically imposed,by the order of their nucleotides. Don’t forget the lipids nowfats and oils they know howto store energy long term.

Water is an inorganic compoundneeded by every living thing.Water is polar in its nature,so that’s why all its molecules cling.

ENZYMES

• Tune of: Row, Row, Row your boat.

ENZYMES

Enzymes have substrateswhich they catalyze.

The active site is where they bind. They’re very specialized.

Each enzyme will work with only one substrate.

They drop the need for energy and increase reaction rate.

Enzymes will break down when temperatures get high.

pH must also be in range or enzyme function dies.

The enzyme is like a key. The substrate’s like a lock.They fit together perfectlyjust like a foot and sock.

CELL ORGANELLES

Tune of : My Girl

CELL ORGANELLES

There’s a membrane all around the cell,

and what goes in and outIt’s sure to tell.Mitochondria

they provide the energy for organelles,Cell organelles – organelles.

There’s a ribosome, making proteins for the cell.

And a golgi apparatusthat will package them well.

Endoplasmic reticulum aids the cell’s transport system.

They’re organellescell organelles – organelles.

The plant cell is something unique.Its chloroplasts, the sunlight they seek.

The cell wall goes all aroundKeeping the plant cell tightly bound

They’re organelles,Cell organelles - organelles

PHOTOSYNTHESIS

Tune of: She’s Got A Ticket To Ride.

PHOTOSYNTHESIS

Photosynthesis is done by producers.They absorb the light and become a

food source. carbon dioxide and water,with energy from the sun

Enter a chloroplast and sugars come out.

The light reaction absorbs photons you see,

And uses them to make ATP.

Carbon dioxide and water with energy from the sun

enter a chloroplast and sugars come out.

The Calvin cycle performs the synthesis.

Storing energy is high on its list.

Carbon dioxide and water,with energy from the sun,

enter a chloroplast and sugars come out.

ECOLOGY

• Tune of: When the Saints Go Marching In.

ECOLOGYEcology, is all about,

the interactions that exist,between the non-living environment

and the organisms on the earth.

Producers, are green plants and algae.They take the sunlight with its rays,and convert it into chemical energy,

that consumers eat everyday.

Each trophic level,Loses 90%, of the energy that exists,

In each lower trophic level of the energy pyramid.

DNA – RNA - PROTEINS

• Tune of: Three Blind Mice

DNA – RNA - Protiens

Replication, copies DNA. The Molecule unwinds and unzips.Then free bases join at the tips, to

make two DNA, two DNA.

Transcription, makes RNAThymine is no longer a base. Uracil

now takes its place In a new single strand,A new single strand.

Translation, is protein synthesis.Three bases of RNA,

make up the codons that show the way

for amino acids, joined by peptide bonds

DNA

• Tune of: Heard It Through The Grapevine

DNA

Well DNA is what your parents useto pass their traits on to you.

A nucleotide of DNA contains a sugar, phosphate, base.

Cytosine and guanine are always there.Adenine and thymine do their share.

You know they’re working out the gene code.

Making proteins as your cells grow.They’re working out the gene code.

The sequence of bases lets your cells know.That’s genetics yeah.
