CHEMiSTRY
OF LiFE
SUMMARY
, D All living organisms are made up of atoms which
THE CHEMISTRY OF LIFE A
combine chemically to form molecules. Which make up
the basic units of life
RELATIONSHIP BETWEEN ATOMS,
ELEMENTS, MOLECULES AND COMPOUNDS
combine chemically X
ELEMENTS to form COMPOUNDS
A
Made consists
up of of
W
combine chemically MOLECULES
ATOMS -
to form
7
Plant and animal cells have complex structures which help them carry out the 7 characteristics of life
MOVEMENT,
EXCRETION,
RESPIRATORY,
NUTRITION,
GROWTH,
REPRODUCTION,
SENSITIVITY
Cells are differentiated
- form tissues that perform certain functions
Tissues form organs which are also specialized to perform particular functions
Definitions :
ATOM: the smallest unit of matter that can take part in a chemical reaction
MOLECULES: Two or more atoms that combine with one another chemically
ELEMENTS: A pure substance that is NOT made up of simpler substances
COMPOUND: A pure substance that is made up of simpler substances ( two elements chemically combined)
CELL: The smallest unit of life that contains cellular inclusions, known as organelles
TISSUES: A group of similarly differentiated cells that perform a common function
ORGANS: A group of different tissues, each of which performs its own functions, but together performs a common function
