Unit Two Bio Flashcards
Magnification
How large an object appears
Resolution
The clarity of the object being observed
Cell membrane
Regulates what enters and leaves
DNA
Found in eukaryotes and in nucleus
Ribosomes
Can be free flowing or attached to an organelle
Makes proteins using nucleic acids
Cytoplasm
Semi-liquid within the cell membrane
Tissues
Group of cells
Organs
Group of tissues
Has DNA
Eukaryotic
Many membrane bound organelles
Eukaryotic
Unicellular
Prokaryotic
Only organelle is ribosomes
Prokaryotes
Chloroplast and cell wall
Plant cels
Smaller vacuoles rather than one big central vacuole
Animal cells
Centrioles and lysosomes
Animal cells
Location of DNA
Nucleus
What surrounds the nucleus
Nuclear membrane
What allows needed materials into and out of nucleus
Pores in the nuclear membrane
Site of synthesis of ribosomes
Nucleus
Energy transducers
Change energy from one form to another
Chloroplasts
Responsable for photosynthesis
Stack of thylakoids
Granum
Mitochondria
Location of cellular respiration
Ribosomes
Responsable got polypeptide synthesis
RER
Responsable for moving things around cell
Ser
Site of synthesis and metabolism of lipids
Contractile vacuole
Plumps out freshwater in unicellular protists
Cell adhesion
Proteins from adjoining cells may hook together
Simple diffusion
Movement from particles of high concentration to low concentration
Facilitated diffusion
Large and charged particles use transport protein to let them through plasma membrane
Active transport
Membrane proteins use energy in the form of atp to pump molecules from low to high concentration
Osmosis
Water molecules move from high to low concentration of water molecules
Stomata
Pores for gases and water
Guard cells
Open and close stomata
Chlorophyll
Pigment in chloroplast that absorbs light
What goes in photosynthesis
Carbon dioxide, water, and light
What comes out due to photosynthesis
Oxygen and glucose
Anaerobic cellular respiration
Plants and yeast produce carbon dioxide from glucose when oxygen isn’t present
