Phagocytosis & Pinocytosis – Biology Mid Exam
The key terms of Biology Mid Exam include, Phagocytosis & Pinocytosis, Exocytosis process, invagination of the cell membrane, two parts of a phospholipid, hydrophilic head, hydrophobic tail, hypertonic solution, phagocytosis short def, pinocytosis short def, phagosome, golgi bodies.
How are larger molecules taken in?
they are engulfed by an invagination of the cell membrane and carried into the cell surrounded by a vesicle
How does phagocytosis work?
cell membrane extends around particle and forms a phagosome around it
How does pinocytosis work?
cell membrane invaginates or pinches around the particle and forms a vesicle
exocytosis process
golgi bodies package the molecules into vesicles which are shipped to and merge with the cell membrane. The molecules are then released by fusion
what does pinocytosis take in
broken-down or dissolved food (nutrients)
what does phagocytosis take in
bacteria, white blood cells, food particles
what are the two parts of a phospholipid
hydrophilic head and hydrophobic tail
what is a solute
a compound that can be dissolved by water
what will happen to a cell placed in a hypertonic solution?
it will shrink up and won’t be able to do its job
hypertonic + water
gain
hypotonic + water
lose
active transport can move substances against their
concentration gradient
Pinocytosis short def
movement of solutes or fluids into a cell
phagocytosis short def
movement of large particles into a cell
