4. All living things move in some way. This may
be obvious, such as animals that are able to
walk, or less obvious, such as plants that
have parts that move to track the movement
of the sun.
5. Respiration is a chemical reaction that
happens within cells to release energy from
food.
6. The ability to detect changes in the
surrounding environment.
7. All living things grow. An increase in size,
amount, or volume, usually as a result of an
increase in the number of cells. Growth of an
organism may stop at maturity, as in the case
of humans and other mammals, or it may
continue throughout life, as in many plants.
8. The ability to reproduce and pass genetic
information onto their offspring. Cell
reproduction usually involves division of a
cell into two identical parts by means of
mitosis or into four different parts by
meiosis.
9. Getting rid of waste. The elimination by an
organism of waste products, such as carbon
dioxide and urea, resulting from metabolic
processes. Higher animals have specific
organs of excretion, such as the lungs and
kidneys. In plants and many lower organisms,
waste is eliminated by diffusion to the
outside environment.
10. The intake and use of nutrients. This occurs
in very different ways in different kinds of
living things. This is also the process by
which an organism obtains the nutrients
needed for growth and metabolism.
