Cells
Storage organelles; larger in plants
vacuoles
Most powerful microscope; uses electrons to form an image
electron microscope
organic molecules made of simple sugars; sources of quick energy
carbohydrates
theory that explains the properties of cells and exceptions
Cell theory
all the chemical reactions of an organism
metabolism
cell wall
Provides support for plant and algae cells
low power microscope used to form a 3-d image for dissection
dissecting microscope
lipids
organic molecules that store energy and make up part of cell membrane
Cell study technique used to dye cell organelles so they are more visible
staining
the maintenance of internal stability
homeostasis
chloroplasts
perform photosynthesis ; found in plant and algae cells
separates cell parts on the basis density
ultracentrifuge
organic molecules that function as enzymes and make up part of cell membrane
proteins
Cell membrane; surrounds the cell and controls what enters and exits
plasma membrane
using smaller materials to build larger materials
synthesis
food vacoule
digest food in unicellular protists
tiny instruments used to dissect cells and/or transfer cell organelles
micro dissection instructions
when molecules move from high to low over the cell membrane; no energy is used
diffusion
molecules that contain both carbon and hydrogen
organic
contractile vacuole
pump water out of unicellular protists
1 millimeter= 1000 micrometers small unit of measurements for microscopic specimens
micrometer
watery fluid that fills cells
cytoplasm
a high energy molecule cells need to carry out life functions
ATP
