- endoplasmic reticulum
- passageways that carry proteins and other materials from one part of the cell to another
- cytoplasm
- the region between the cell membrane and the nucleus
- cell membrane
- controls the substance that come into and out of a cell
- diffusion
- the process by which molecles move from an area of higher concentration to a area of lower concretion.
- mitochondria
- the "powerhouse" of the cell. it provides energy to the cell
- lipids
- are energy rich organic compounds made of carbon,hydrogen,and oxygen,and they contain more energy than carbohydrate
- chloroplast
- the storage areas of cells
- nucleus
- the "brains" of the cell
- cell
- the basic unit of structure and function in living things
- cell wall
- protects and supports the cell
- ribosomes
- factories that reporduce proteins
- cell theory
- the widely accepted explantion of the relationship between cells and living things
- Golgi bodies
- recieve proteins and other newly formed materials from the endoplasmic.
- passive transport
- the movement of dissolved materials througha cell membrane without using cellular energy
- RNA
- plays a important role in the production of proteins
- selectively permeable
- which means that some substances can pass through the membrance while others cannot
- organelle
- tiny structures in a cell that carries out a specfic function within a cell
- lysosomes
- atre small,round structures containing chemicals that break down
- carbohydrate
- an energy-rich organic compund made of the elements carbon,hydrogen,and oxygen.
- microscope
- an instrument that makes small object look larger
- amino acids
- a small molecle that is linked chemically to other amino acids to form proteins
- osmosis
- the diffusion of water molecules throught a selctively permeable membrane
- Nucleic acids
- are very long organic molecules made of carbon,hydrogen,nitrogen,and phosophorus
- proteins
- are large molecules made of carbon,hydrogen,oxygen,nitrogen,and in some cases sulfur
- active transport
- the movement of materials through a cell membrance using energy
- DNA
- the gentic material that carries material about an organism
