Give the layers of cross section of leaf and state the role of each layer
Cuticle- waxy to avoid water loss
Upper Epidermis- thin single layered for light to pass through
Palisade mesophyll- maximum chloroplast for photosynthesis
Spongy mesophyll - spaces for gases to pass through it
Lower Epidermis- presence of stomata

Changes that take place in our body during respiration
Ribs go outward and upward, lungs expand, pressure inside the lungs decreases, diaphragm flattens
