What causes cells to shrink
Hypotonic- lowest concentration of solutes. Has more water. Cells moves by water. WATER ENTERS=CELL SWELLS/BURST
Hypertonic- WATER LEAVES=CELL SHRINKS/SHRIVELS
IT SHRINKS BECAUSE THE WATER MOLECULES WILL MOVE OUT OF THE CELL CAUSING IT TO LOSE MASS
4 organelles and their functions in eukaryotic cells
Mitochondria- does ATP energy through cellular respiration
Nucleos- contains DNA
Golgi Apparatus- packages proteins and lipids for transport
ER- helps transport protein and lipids
Water Potential
-2
Endosymbiosis’ Theory 3 pieces of evidence that proves it
The mitochondria and chloroplasts contain DNA AND RIBOSOMES AND THE REPRODUCE THROUGH BINARY FISSION. THEY HAVE DOUBLE MEMBRANE
How does polar large molecules can get through the membrane
Transport Portiens like carrier proteins which is Facilitated diffusion.
Without the cell expending extra energy
helps large molecules like
The transport proteins because no ATP or required. They move from low to high concentration. Uses channel or carrier proteins
Since they’re not compatible with the non polar tails of the membrane it’s hard for them pass though so facilitated diffusion without energy
Channel proteins change the shape to move it across their membrane and release it to the other side
so that have a harder time passing through
