Hon Bio Unit 1

yeah

cells (made of)

basic unit of life, living things are made of one or more cells

Growth

To increase in size or number of cells

Need for materials and energy

Organisms can obtain energy by eating or using the sun to make food. Other molecules act as building blocks for body structures.

Reproduce

The process of producing new organisms.

Maintaining internal balance

homeostasis-process by which organisms keep their internal conditions relatively stable

Response to the enivironment

organisms react to stimuli in their environment

selectively permeable

membranes that allow some substances through but not others

Diffusion

Movement of molecules from an area of higher concentration to an area of lower concentration.

Biomolecules/Macromolecules

organic molecules which combine to form living organisms; includes carbohydrates, lipids, proteins and nucleic acids

Carbohydrates

Broken down to glucose to provide energy.

Lipid

Energy-rich organic compounds, such as fats, oils, and waxes, that are made of carbon, hydrogen, and oxygen.

Protein

A compound that is made of one or more chains of amino acids; important for building cellular structures

Nucleic Acid

genetic material, as DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.

Monomer

building blocks of polymers

Polymer

molecules composed of two or more monomers; makes up macromolecules

Glycerol

A monomer of lipids

fatty acids

a monomer of lipids

Polypeptide

Another word for protein

amino acids

a monomer of protein

Nucleiotide

monomer of nucleic acids

Polysaccharides

large macromolecules formed from monosaccharides

Monosaccharides

monomer of carbohydrates

membrane proteins

Embedded proteins that allow large molecules to cross the cell membrane.

cell membrane structure

phospholipid bilayer with embedded proteins

cell membrane function

Controls the movement of substances into and out of the cell

Based on a universal genetic code

All but a few bacteria use DNA as the system of inheritance.

Development

the process of change that occurs during an organism's life to produce a more complex organism

Evolution

A GROUP of organisms changing over time
