one

Some organisms consist of just ___ cell.

cytoplasm

The cellular material outside the nucleus is called the

The division of the nucleus in reproductive cells is called:

adenosine diphosphate

The energy molecule "ATP" is a product of the reactant

ATP

The energy required for the mechanism of "active transport" comes from the product of ___ decomposition

cell wall

The fibrous outer covering surrounding plant cells is the

semipermeable

The plasma membrane allows some molecular species to enter and excludes others. It is therefore referred to as a _________ membrane

The plasma membrane is made chemically of a molecule that has both polar and nonpolar ends and contains _____ inside its structure.

high

The relative concentration of water in a hypotonic solution is

nucleus

The spherical object within a cell which controls its activity is called the

organ

Two or more tissues which cooperate as a unit are considered a(n

hypotonic

When an animal cell is placed in a _______ solution it will gain water and may burst

active transport

When the cell concentrates potassium within, against the natural tendency of matter, it is performing:

osmosis

When water moves freely from a membrane containing a higher concentration to a lower concentration, the diffusion is called

excretion
