The Science of Life Biochemistry Cell Structure and Function Homeostasis & Transport Chemistry of Life

The study of life

BIOLOGY

These are instructions for traits that can be passed from one generation to the next

GENES

The maintenance of a stable, balanced environment inside of a cell and/or whole organism

HOMEOSTASIS

If a microscope has an ocular lens (eye piece) that magnifies 10X and an objective lens that magnifies 40X, what is the total magnification?

400X (10 x 40)

The smallest units of life that can carry out all of the functions of living things

CELL

A substance made of only one type of atom

ELEMENT

These atomic particles are found outside of the nucleus in various energy levels

ELECTRONS

Electrons are shared in this type of bond

COVALENT

Anything below 7 on the pH scale

ACIDS

These are biological catalysts that speed up reaction rates inside of cells

ENZYMES

All organic compounds must contain this element

CARBON

Sugars such as cellulose, sucrose, glucose, galactose, and lactose are all examples of what macromolecule family?

CARBOHYDRATES

DNA and RNA are examples of what macromolecule family?

NUCLEIC ACIDS

You store your excess glucose in molecules of glycogen, while plants store their excess glucose in this molecule.

STARCH

Monosaccharides are the monomers of carbohydrates, while amino acids are monomers of this macromolecule family.

PROTEINS

While looking at dead plant cells (cork), this man discovered cells

HOOKE

A bacterium, which is a cell with no nucleus, is an example of this type of cell

PROKARYOTE

A structure inside of a cell that carries out a specific function

ORGANELLE

All cells must have three things: 1) Cell membrane 2) Cytoplasm 3) ?

GENETIC INFORMATION (DNA)

This cell part plays the role of an “intracellular highway” moving molecules from one place to another

ENDOPLASMIC RETICULUM

The movement of water across a selectively permeable membrane down its concentration gradient

OSMOSIS

Passive transport moves molecules down their concentration gradient until equilibrium is reached. The three types of passive transport are: 1) Diffusion 2) Osmosis 3) ?

FACILITATED DIFFUSION

You place a cell into a solution and it shrinks bc it lost water. What kind of solution did you put it in to?

HYPERTONIC

Type of active transport that moves large molecules or materials into a cell

ENDOCYTOSIS

Salt crystals dissolving in water is an example of this type of passive transport

DIFFUSION

FINAL JEOPARDY Provide names for cell parts 1-5

FINAL JEOPARDY ANSWER 1 – Endoplasmic reticulum 2 – Nucleus 3 – Mitochondria 4 – Cell Membrane 5 – Golgi Apparatus
