- cell: basic unit of structure and funcion in all living things
- cell membrane: a thin flexible barrier that surrounds the cell
- cell wall: a rigid barier surrounding plant cells made up of cellulose which prevents plants from moving
- celluar respiration: the process by which mitochondria break down sugar (glucose) into carbond dioxide and water releasing energy
- chloroplast: found in plants that contain a green pigment chlorophyll that gives plant their green color are used to make food for a plant cell--they are not found in an animal cell
- chromatin: a grandular materail spread throughout the nucleus that is made up of DNA
- chromosomes: threadlike structures that is made up of condensed chromatin
- cytoplasm: the liquid located inside a cell between the cell membrane and the nucleus
- endoplasmic reticulum: is an organelle that makes parts of the cell membrane and chemically change some proteins
- eukaryotic cells: cells that contain nucleus and other structures that surrounded by a cell membrane
- golgi vesicles: attaches carboydrates and lipids to proteins
- lysosomes: break down food particles that are taken into the cell and organelles that are not longer needed by the cell
- mitrochondria: organelles responsible for releasing energy from stored food molecules to power all cell functions
- nucleolus: a dense region inside the nucleus where ribosomes are assembled
- nucleus: a large strudcture inside a cell that contains genetic material and controls the cell's activitiews
- organelles: tiny structures located in the cytoplasm
- prokaryotic cells: cell that do not have a nucleus or membrane bound organelles
- ribosomes: are small structure made up of RNA and proteins-- a they make proteins
- rough endoplasmic reticulum: endoplasmic reticulum that have ribosomes attache to it
- smooth endoplasmic reticulum: endoplasmic reticulum that doesnt have ribosomes attache to it
- vacuole: a large organelle that is found in plants that stores water and other dissolved minerals
