31 Cards in this Set

  • Front
  • Back
cytology
branch of biology that studies cells and their parts
organelles
tiny cell parts doing particular jobs
cytoplasm
liquid in cell that seperates and floats organelles
cell membrane
holds all the protoplasm together
cell wall
protects and supports the cell; made of cellulose, older ones have lignin
lignin
cell hardener
Nucleus
controls all the cell's functions; holds all the DNA/chromatin for making cell's proteins
Nucleolus
A large dot or 2 in the Nucleus; copies the DNA one at a time to make proteins
Endoplasmin Reticulum
A network of tiny tubes running from the pores of the Nucleus to the pores of the membrane; transportation device for the info from the nucleus and materials to the organelles
Water Vacuole
Stores extra water in plants; sometimes pushes Nucleus
Food Vacuole
digests and traps food chunks in unicellular animals
Contractile Vacuole
removes waste water from 1celled animals
chromoplasts
found in colored fall leaves and flowers; stores bright pigments like yellow and red
Chloroplasts
makes glucose from H2O and CO2; does photosynthesis
Leucoplasts
white blood cells; bags of white starch; common in potatoe
Ribosomes
lots of tiny dots near the ER; makes proteins for the cell
Mitochondria
releases energy from glucose (cell respiration); organelle really common in muscle cells 'cuz we use so much energy
lysosomes
contains enzymes that could digest/destroy the cell; recycler
Golgi Bodies
stores and delivers proteins, especially enzymes and hormones
selectively permiable
when the membrane decides what it lets in and out of the cell
lipid
fat
cellulose
stretchy material the cell wall is made out of
pore
openings in the membrane
protoplasm
all the stuff in a living cell
Chromatin
relaxed DNA in the Nucleus
enzymes
biological workers; do the work the organelles get credit for
Grana
work stations for enzymes; made of loose pieces of membrane
Photosynthesis
the process of turing light into glucose
Cristae
work stations for enzymes in Mitchondria
cytoplasmic streaming
cytoplasm liquifies and begins to circulate
equation for cell respiration; happens in mitochondria
C6+H12+O6+O2---(enzymes&sunlight)---> H2O+ CO2+Energy
