Cell is the smallest structural and functional unit of an organism, which is typically microscopic and consists of cytoplasm and a nucleus enclosed in a membrane.
Primary cells :
a primary cell, is non-rechargeable, whereas a secondary cell (like a lead storage battery) is rechargeable.

Hope it helps you !
CELL:the smallest living part of an animal or a plant
Difference:
A primary cell cannot be recharged whereas a secondary cell can be recharged.In a primary cell chemical reaction is irreversible whereas in a secondary cell chemical reaction is reversible.The internal resistance is high for a primary cell whereas it is low for a secondary cell.In a primary cell, chemical energy is converted into electrical energy when current is drawn from it whereas in a secondary cell electrical energy is converted into chemical energy when current is passed through it and chemical energy is converted into electrical energy when current is drawn from it. A primary cell is light and less expensive whereas a secondary cell is heavy and expensive
