Cell membranes - correct answer -Act as partitions to protect a
cell from its environment, and to divide the inner structure of a cell
into different parts. External membrane of cells is composed of a
double layer of elongated molecules interspersed with molecular
structures called receptors. Water permeable and ions associated
with nervous system move freely.
Receptors - correct answer -Bond to certain molecules through
hydrogen bonding. Molecules they bond with are specified by the
geometric shape of the molecule and of these. Molecule moves
through the membrane in the body of a cell.
Vesicles - correct answer -After a molecule moves through the
membrane, part of the membrane "snips off" and forms a
protective packet around the molecule called this.
Cell walls - correct answer -What do plants cells have that other
cells don't?

Nucleus - correct answer -Contains cell's DNA, the genetic
material that gives "instructions" for day-to-day chemical activities
of the cell
Organelle - correct answer -Any specialized structure inside a
cell (including the nucleus). Many with different features, but one
of the most important structures controls how cells gain energy
(chloroplasts).
Chloroplasts - correct answer -Organelles that convert sunlight
into usable energy. Contain molecules of Chlorophyll which
absorb energy from sunlight and use that energy to transform
carbon dioxide and water energy into energy-rich sugar molecules
such as glucose.
Mitochondria - correct answer -Organelles where molecules
derived from the sugar glucose react with oxygen to produce the
cell's energy. Oxidation is exothermic, meaning the chemical
reactions occurring within these release energy to be used by the
organism.
