What are the functions any organism must perform in order to survive?

They must move by themselves, metabolize, reproduce, grow and develop, and respond to their environment. Water is very important in organisms as it can act as a solvent, a thermal buffer and is used as a transport medium by complex organisms.
Growth - an irreversible increase in the dry mass of living material. To be classified as a living organism, growth is an essential function.
Reproduction - the ability to form genetically similar individuals (if not genetically identical) by means of sexual or asexual reproduction (or a mixture of the two). Viruses are not classified as organisms as they cannot reproduce on their own, but rely on host cells to reproduce.
Respond to stimuli- the ability to react to environmental conditions. This can vary in complexity - humans have a complex nervous system and endocrine system, whilst plants respond to stimuli by means of plant growth regulators and can display phototropic responses in growing towards light.
Movement - Similar to number 3 in some cases. In animals there is a clear difference, as movement can occur as a result of muscle contraction. In plants, although we would not perhaps say that they 'move' they can grow in response to environmental stimuli, and this is classified as movement.
Nutrition - an organism must 'eat' and this can occur either heterotrophically where organisms gain their food from breaking down organic compounds from producers (i.e when humans eat plants/animals) or autotrophically where the organisms synthesize their own organic compounds (i.e plants which photosynthesise to make organic compounds which can be broken down to produce a respiratory susbstrate)
Excretion - the removal of toxic waste metabolites. In humans we have complex excretory system and have 2 kidneys which filter out urea and other compounds which need to be excreted.
Respiration - the production of ATP from respiration is the final function all living organisms must perform. Respiration can either be aerobic, where oxygen is present, or anaerobic when oxygen is not present. Oxygen is not essential for aerobic respiration, and indeed there are bacteria which are living organisms which do not need oxygen to survive, which live in anaerobic conditions and have evolved mechanisms to respire in the absence of oxygen.

An organism has many specialized cells to carry out the cellular functions it needs to survive what can you determine about this organism?
It has the basic intelligence to respond to its environment and can react to it in order to survive.
When an organism makes itself look like something else in order to survive?
Mimicry
What are the singled cell organisms?
The Cell
A relationship in which organism needs something else in order to survive?
I think that's called Symbiosis.
What cross should a scientist perform in order to determine if the organism is heterozygous or homozygous dominant?
Scientists use a test cross to determine if an organism is heterozygous or homozygous dominant.
An organism has many specialized cells to carry out the cellular functions it needs to survive what can you determine about this organism?
It has the basic intelligence to respond to its environment and can react to it in order to survive.
Does the organism use energy?
yes it has too in order to survive.
A relationship in which an organism needs something else in order to survive?
yes it does
In order to survive all organism must carry out?
hetetrophic nutrition
What are the three processes plants must perform in order to survive are?
The three processes plants must perform in order to survive include respiration, reproduction, and consumption. By performing all these tasks, they are able to survive and create a new generation to carry on.
When an organism makes itself look like something else in order to survive?
Mimicry
What word means a relationship in which an organism needs something else in order to survive?
dependancy
What are the singled cell organisms?
The Cell
What cell does not need to expend energy ATP in order to perform?
No. The cell does need to expend energy in order to perform its life functions.
Distinguish between an autograph and a heterotroph?
An autograph is a persons signature. A heterotroph is an organism that utilises organic molecules in order to grow. An organism that eats other organisms in order to survive.
Why is it important for organisms to adapt?
adaptations are important for organisms because it inherits a trait that helps that organism survive
What four things is an organism made up of in order for it to survive?
The organism needs food, water, homeostasis (body temperature is healthy) and living space.
