Summary of living things 

Living things, described as alive, must perform several vital activities: movement, respiration, nutrition, sensitivity, reproduction, growth and excretion.

Living things, described as alive, must perform several vital activities: movement, respiration, nutrition, sensitivity, reproduction, growth and excretion.

All living things are classified into groups called kingdoms.

As an example, we know humans are alive, but trees are alive too:

  Human Oak Tree
Movement Can run Trees grow towards sunlight, gravity and water. Leaves drop with lack of water
Respiration (the opposite of photosynthesis)(note: this is not breathing) Humans use glucose to make energy (ATP) both aerobically (with oxygen) and anaerobically (without oxygen and produce lactic acid and energy) Trees use glucose to make energy (ATP) both aerobically (with oxygen) and anaerobically (without oxygen and produce ethanol and energy)
Nutrition Humans eat Nutrients are the food that oak trees need for growth, such as taking potash, nitrogen and potassium from the soil
Sensitivity Humans sense their surroundings and react accordingly such as cold and heat or taste Oak trees are sensitive to light, moisture and gravity
Reproduction Have babies Reproduce asexually through cultivation and sexually through the exchange of pollen
Growth Average height 1.7m Grow up to 20 to 40m high
Excretion Go to the toilet Waste removal from stomata in leaves or with dead leaves falling away in autumn
