visible to the naked eye - ANSmacroscopic cells
Discovered cells - ANSRobert Hooke
All living things are made of cells - ANSTheodor Schwann and Matthias Schleiden
Proposed that all cells come from other cells - ANSRuldolf Virchow
cell that does not have a nucleus or other membrane-bound organelles. - ANSprokaryotic cell
have a nucleus and other membrane-bound organelles - ANSEurkaryotic Cells
Plant cells have chloroplasts, a cell wall, and vacuoles while animal cells do not. -
ANSDifferences between plant and animal cells
cell, tissue, organ, organ system, organism - ANSLevels of organization
A group of similar cells that perform the same function. - ANSTissue
group of tissues that work together to perform closely related functions - ANSOrgan
group of organs that work together to perform a specific function - ANSorgan system
A living thing - ANSOrganism
A tiny cell structure that carries out a specific function within the cell - ANSOrganelle
Contains DNA. control functions and activities of the cell - ANSNucleus
Storage and circulation of materials within the cell - ANSCytoplasm
Breaks down energy rich substances then releases the energy - ANSMitochondria
