Biology: Living and Non-Living Things

Study Notes

Similarities Between Living Beings And Non-Living Things

Both living beings and non-living things are composed of matter.
They both occupy space and have mass.
Both are made up of small structural units that cannot be seen with the naked eye and require microscopes to visualize.

Differences Between Living And Non-Living Things

Living beings exhibit unique characteristics that distinguish them from non-living things, including growth, nutrition, movement, reproduction, and excretion.

Characteristics Of Living Organisms

Living organisms possess structural organisation, with cells being the basic 'building block' or 'structural unit' of life.
Growth is a characteristic feature of living organisms.
Movement is a fundamental characteristic of living organisms.
Respiration occurs in living organisms.
Reproduction is a vital function of living organisms.
Living organisms respond to stimuli.
Food and nutrition are essential for living organisms.
Excretion is a necessary process in living organisms.
Living organisms have a definite life span.

Structural Organisation

A cell is the basic structural and functional unit of life.
Cells divide to form new cells, and all functions necessary for life take place within a cell.
Organisms can be classified as unicellular (made up of one cell) or multicellular (made up of multiple cells).
Examples of unicellular organisms include Amoeba and Paramecium.
