ScienceInside a Leaf: Labelled Leaf Cross-Section
A labelled cross-section of a leaf, from the waxy cuticle to the stomata. See how each layer, from palisade cells packed with chloroplasts to air spaces, veins and guard cells, helps the leaf photosynthesise.
ScienceHow Photosynthesis Works: From Sunlight to Sugar
Photosynthesis is how plants use light energy to turn carbon dioxide and water into glucose, releasing oxygen as a by-product. It happens in chloroplasts in two linked stages: the light-dependent reactions and the Calvin cycle.
ScienceHow Vaccines Work: Training Your Immune System
Vaccines work by imitating an infection. They show your immune system a harmless antigen from a germ, so it makes matching antibodies and memory cells that can fight the real germ quickly if it ever arrives.
ScienceThe Human Digestive System: How Food Becomes Energy
The digestive system breaks food into nutrients small enough to enter the blood. Food passes from the mouth through the oesophagus, stomach and intestines, helped by juices from the liver, gallbladder and pancreas.
SciencePlant vs Animal Cells: What Each Part Does
Plant and animal cells share a nucleus, cell membrane, cytoplasm, mitochondria and ribosomes. Plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. This comparison poster shows each part and its job.
