|
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
|
