Question 1
Identify life processes that are characteristic of living organism
Life processes are the basic activities and functions performed by living organisms in
order to survive on earth. There are seven common life processes posses by all living beings.
However, it includes movement, reproduction, sensitivity, growth, respiration, excretion and
nutrition (Mohamad and et. al., 2014). Moreover, it also consist several characteristics such as
order, response to stimuli, reproduction, growth & development, regulation, homoeostasis and
energy processing.
Structure of human cell and function of its parts
Cell can be described as basic structural and functional unit of life. Human body is
composed of trillions of cells and plays an important role to organise body structure, absorb
nutrient from food to convert it into form of energy and conduct specialised functions
accordingly. However, the hereditary material of body is also exist in the cell and replicate
themselves.
Structure of the cell composed various parts which can be consider as organelles having
their different functions. It includes cytoplasm, cytoskeleton, endoplasmic reticulum (ER), Golgi
apparatus, lysosomes & peroxisomes, mitochondria, nucleus, plasma membrane and ribosome.
Function of organelles
