Topic 3 - Photosynthesis Flashcards
what does photosynthesis produce?
glucose
where on a plant does photosynthesis happen?
in the leaves of green plants
where in a cell does photosynthesis happen?
inside the chloroplasts
what do chloroplasts contain that aids photosynthesis, and what does it do?
chlorophyll, which absorbs sunlight and uses its energy to convert CO₂ and water into glucose.
what is the word equation for photosynthesis?
carbon dioxide + water = glucose + oxygen
what is the symbol equation for photosynthesis?
6CO₂ + 6H₂O = C₆H₁₂O₆ + 6O₂
how is the shape of leaves adapted for efficient photosynthesis?
leaves are broad so there is a large surface area exposed to light
how is the palisade layer adapted for efficient photosynthesis?
most of the chloroplasts are found in the palisade layer, because they are near the top of the leaf where they can get the most light
how is the upper epidermis adapted for efficient photosynthesis?
its transparent so light can pass through to the palisade layer
how are the vascular bundles adapted for efficient photosynthesis?
they deliver water and other nutrients to every part of the leaf and take away the glucose produced by photosynthesis
how is the waxy cuticle adapted for efficient photosynthesis?
helps to reduce water loss by evaporation
what else makes photosynthesis more efficient?
the adaptations of leaves for efficient gas exchange
