What do you already know about the characteristics of living things?
Characteristics of Living Things
Living things share seven characteristics: movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition.
Movement in Plants
Plants move by growing towards light (phototropism) and opening/closing flowers.
Respiration in Plants
Plants respire by taking in oxygen and releasing carbon dioxide through their leaves.
Sensitivity in Plants
Plants respond to stimuli, such as light and touch (e.g., Venus flytrap).
Growth in Plants
Plants grow by cell division and enlargement, often towards light.
Reproduction in Plants
Plants reproduce through seeds, spores, or vegetative parts.
Excretion in Plants
Plants excrete oxygen as a waste product of photosynthesis.
Nutrition in Plants
Plants make their food through photosynthesis using sunlight, CO2, and water.
Animal Movement
Animals move using muscles, legs, wings, or fins.
Animal Respiration
Animals breathe using lungs, gills, or skin.
Animal Sensitivity
Animals respond to stimuli with senses like sight, sound, and touch.
Animal Growth
Animals grow by increasing in size and cell number.
Animal Reproduction
Animals reproduce by giving birth or laying eggs.
Animal Excretion
Animals excrete waste through urine and faeces.
Animal Nutrition
Animals obtain food by eating plants or other animals.
What is Photosynthesis?
Photosynthesis is the process where plants make food using sunlight, CO2, and water.
Leaf Features for Photosynthesis
Leaves have a large surface area, chlorophyll, and stomata for photosynthesis.
Understanding Digestion
Digestion breaks down food into nutrients the body can use.
The Alimentary Canal
The alimentary canal includes the mouth, oesophagus, stomach, intestines, and more.
