MAIN POINTS
The Characteristics
Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition
Movement

An action by an organism or part of an organism causing a change of position or place.

Animals must move about and search for food.
Respiration
 The chemical reactions that break down nutrient molecules in living cells to release energy.
 Water and carbon dioxide are produce and excrete as waste materials.
HUMAN AND SOCIAL BIOLOGY
 There are two types of respiration (aerobic and anaerobic)
Sensitivity

The ability to detect or sense changes in the environment (stimuli) and to make responses.
Growth




A permanent increase in size or weight.
It includes the replacement of worn-out parts of the body.
An increase in cell number or cell size or both.
Growth requires an organism to take in material from the environment and organize
the material into its own structures.
Reproduction




The processes that make more of the same kind of organism.
Humans must reproduce if the group is to survive.
Reproduction is often an extension of the growth process. e.g.
There are two types of reproduction. (Sexual Reproduction and Asexual Reproduction)
Excretion



The removal from organisms of toxic materials, the waste products of metabolism (chemical reactions in cells including
respiration) and substances in excess of requirements.
Excretion is only concerned with the removal of waste produced by metabolism.
Removal of undigested food from the intestine is called elimination or egestion.
HUMAN AND SOCIAL BIOLOGY
Nutrition


EVALUATION
ONE
The taking in of food into the body, in order to make energy and
provide the materials for building up the body parts.
The taking in of nutrients which are organic substances and mineral
ions, containing raw materials or energy for growth and tissue repair,
absorbing and assimilating them.
Students will answer the following questions

In what ways do living and non-living things differ?
Give two reasons why nutrition is needed in humans.
Which characteristic is shown by the taking in of food into the body?
State the two types of respiration.
What is the removal of undigested food from the intestine called?
Why is the elimination of undigested food not excretion?
Explain to your sister why is respiration so important?
What is it called when energy is released from nutrient in the body's cells?
If you quickly remove your hand from a hot plate, what characteristic of organisms are you showing?
Explain how your responses to stimuli may be useful.
