Origin of Life Flashcards
(132 cards)
Balance/normal/average
Homeostasis
simple to complex, unicellular, multicellular
Organization
sum total of all chemical reactions in the body
Metabolism
fit, survive, adjust, change
Adaptation
size, shape, complexity, quality and quantity
Growth and development
Irritability, Environment, reaction
Response to stimulus
proliferation of organisms, gametes, sex
Reproduction
Two types of transport of cell amterials
Passive and ACtive
Cell doesn’t use energy (no utilization of ATP - Adenosine Triphosphate);
- molecules move randomly;
- no need for oxygen; and
- molecules move from an area of high concentration to an area of low
concentration. (It follows concentration gradient
Passive transport
It involves random movement of substances or molecules
from an area of high concentration to an area of low concentration.
Diffusion
the flow of materials, whether solvent or solute,
is from greater to lesser concentration
Concentration gradient
It is the movement of specific particles through
specific carrier proteins situated in the membrane. This also follows the
concentration gradient.
Facilitated diffusion
It is the movement of water across membranes. Water moves
from high to low concentration
Osmosis
Cells use energy (with utilization of ATP-Adenosine Triphosphate); and
- Movement of molecules from an area of low concentration to an ares high
concentration (against the concentration gradient).
Active transport
It transport proteins that require energy to do work
Protein pumps
It is taking bulky substances into a cell
Endocytosis
It is the transport of large molecules
Bulk transport
It is taking bulky substances out of a cell.
Exocytosis
cell eating
Phagocytosis
Cell drinking
Pinocytosis
A type of solution with
high concentration of
solute inside the cell, thus
water enters the cell
Hypotonic solution
A type of solution with
higher concentration of
solute outside the cell,
thus water leaves the cell.
Hypertonic solution
A type of solution where
the concentration of
solute outside the cell is
equal to that within the
cell, water moves equally
in both directions
Isotonic solution
Living organisms consist of one or more cells that are connected
to one another
Organization
