What are the eight characteristics that define living organisms?

Movement, Respiration, Sensitivity, Homeostasis, Growth, Reproduction, Excretion, Nutrition.

How can the characteristics of living organisms be remembered?

Using the mnemonic Mrs. H Gren.

What is the role of movement in living organisms?

Movement allows animals to get to their prey and enables plants to respond to sunlight and gravity.

What is aerobic respiration?

What are excretory organs in plants and animals?

Kidneys in mammals and stomata in plants.

What is the difference between heterotrophy and autotrophy?
