The correct answer is All of the above.
Key Points
- Living organisms share characteristics such as the ability to move and reproduce.
- There are different types of living organisms including plants, animals, fungi, bacteria, and protoctists.
- Characteristics of living organisms:
- Movement - they can move and change their position.
- Reproduction – they can make more of the same kind of organism as themselves.
- Sensitivity – they can detect or sense stimuli and respond to them.
- Growth - they can permanently increase their size or dry mass by increasing the number or size of their cells.
- Respiration – they can create chemical reactions that break down nutrient molecules in living cells to release energy.
- Excretion – they can excrete toxic materials, waste products of metabolism, and excess substances.
- Nutrition - they can take in and absorb nutrients such as organic substances and mineral ions. These nutrients contain the raw materials or energy needed for growth and tissue repair.
Additional Information
- Cells are the building blocks of every living organism.
- Two-thirds of a cell is composed of water and is made up of biological molecules such as proteins and lipids.
- They provide a definite structure to the body, help to break down food, and release energy which is used up by our body to perform multiple tasks throughout the day.
