cytology Flashcards
cell membrane
Phospholipid bilayer, separates the inside of the cell from its surroundings, controls what enters and exits
cell wall
tough outer covering only found in plant + bacterial cells, protects and gives plant cell straight 3-D edges
nucleus
control center of a cell, mRNA goes into cytoplasm, contains DNA
vacuole
membrane bound storage sac, stores food, water, or waste
mitochondria
Changed energy stored in food into ATP (energy carrying molecule in all living things)
DNA
Found inside cell, molecule that carries genetic information for the development and functioning of the cell
cytoplasm
gel like soup made of protein, amino acids, carbohydrates, and monosaccharides, keeps organelles floating
prokaryote
3.5 billion yrs old, always unicellular, smaller than eukaryotes
eukaryote
1.5 billion yrs old, may be unicellular or multicellular, larger than prokaryotes
micrometer
measurement of cells
lysosome
contain enzymes which break down substances brought in, white blood cells have lysosomes
spontaneous generation
The idea that living creatures can from from non living matter (there is no such thing)
cytoskeleton
Microtubules + microfilaments, help maintain animal cell shapes
extracellular fluid
Fluid that is in body, found in blood
centriole
organize microtubules that serve as the cells skeletal system
contractive vacuole
golgi apparatus
rough ER
nucleolus
chloroplasts
ribosome
flagellum
central vacuole
histone
fluid mosaic
microvilli
smooth ER
cell theory
eukaryote
cilla
