Characteristics of Living Organisms:
Movement ­ being able to change position in order to carry out other life
Respiration ­ creating energy through respiration.
Sensitivity ­ being able to respond to our environment (e.g. our pupils
getting bigger in the dark)
Nutrition ­ taking in substances that bodies/organisms need in order to

Examples include mammals (for example humans) and insects (for example

These are organisms that are not able to carry out
photosynthesis; their body is usually organised into a mycelium
made from thread like structures called hyphae, which contain
many nuclei; some examples are single-celled; they have call
walls made of chitin; they feed by extracellular secretion of
digestive enzymes onto food material and absorption of the
organic products;…read more

Examples include Lactobacillus bulgaris, a rod
shaped bacterium used in the production of
yoghurt from milk.
These are small particles, smaller than bacteria; they are

and sizes; they have no cellular structure but have a protein coat
and contain one type of nucleic acid, either DNA or RNA.
Parasites take things from other living organisms.…read more
