Science Unit 2 (cells) Flashcards
the smallest structural and functional unit of all things
cells
one of the smallest bodies in a cells cytoplasm that are specialized to perform a specific task
organelle
the smallest unit of an element that maintains the property of that element
atom
a fat molecule-example oils, waxes, and steroids
lipid
a system of membranes that is found in a cells cytoplasm and that transports proteins and in the production of lipids
endoplasmic reticulum
a cell organelle that helps make and package materials to be transported out of the cell
golgi complex
breaks down waste
lysosomes
a structure made up of a collection of tissues that carry out a specialized function
organ
a living thing; anything that can carry out life processes independently
organism
controls the activities of the cell
nucleus
class of molecules that includes sugars, starches, and fiber
carbohydrate
form much of the cell membrane
phospholipids
uses light energy to make glucose or food
chloroplast
group of organs that work together to perform body functions
organ system
the special, normal, or proper activity of an organ or part
function
controls materials in and out of the cell
cell membrane
single-celled organism that does NOT have a nucleus or membrane bound organelles (bacteria)
prokaryote
group of atoms held together by chemical forces
molecule
made up of amino acids; builds and repairs body structures
proteins
stores food and water
vacuole
makes proteins
ribosomes
work together to accomplish a function such as digesting food (group of similar cells)
tissue
the fluid inside the cell membrane and all thee organelles (jelly-like)
cytoplasm
organism made up of cells that have a nucleus (humans,plants, and fungi)
eukaryote
