Transport Flashcards
Active Transport
the movement of substances from a dilute solution to a more concentrated solution against a concentration gradient, requiring energy from respiration
Chyle
droplets of emulsified fat
Columnar Cells
tall, narrow cells that absorb substances passed into blood and lymphatic vessels, with microvilli on the surface
Condensation
process by which clouds are formed
Decay
also known as decomposition, the process by which decomposers break down dead plant and animal material, breaking down complex substances into more simple substances
Decomposers
microorganisms that break down substances
Evaporation
the process by which liquid is heated and becomes a gas
Goblet Cells
cells that are rounded at one end and secrete mucous into the intestinal cavity
Hypertonic
a solution in osmosis that is more concentrated than the cell
Hypotonic
a solution in osmosis that is less concentrated than the cell
Isotonic
a solution is osmosis that in equal concentration with the cell
Lymphatic Vessels
remove droplets of emulsified fat
Mucosa
a mucous membrane
Mucous-Membrane Layer
mainly composed of two cell types: columnar cells and goblet cells
Osmosis
a type of diffusion where water passes over a partially permeable membrane from a dilute solution to a concentrated solution
Plasmolysis
where the cell membrane pulls away from the cell wall, causing the cell to die
Precipitation
the process by which rain falls
Reverse Osmosis
the process by which molecules of a solvent pass through a semi-permeable membrane in the opposite direction to normal
Run-Off
the process by which rain runs off the land into the sea
Short Diffusion Pathway
the theory that particles will diffuse faster across shorter distances than they do across longer distances
Stand of Muscle
allows villi to contract and expand, emptying the contents of the lacteal into larger lymphatic vessels
Translocation
movement of dissolved sugars from the leaves to the rest of the plant
Vasculature
the vascular system of a part of the body
Ventilated
movement of air or water into and out of a gas exchange organ
