S1 - Photosynthesis and Biodiversity (complete) Flashcards
This deck covers the Photosynthesis and Biodiversity topic covered in S1 Science. Photosynthesis and Biodiversity is a Biology topic.
Organism
A living thing.
The process used by green plants to make food.
Photosynthesis
Which two substances are required for photosynthesis?
Carbon dioxide and water
Which two substances are made during photosynthesis?
Glucose and oxygen
(glucose/carbohydrates/sugars all OK)
The green pigment inside chloroplasts that captures light.
Chlorophyll
Chloroplast
Tiny structure inside plant cells where photosynthesis happens.
Release of energy from sugars that happens in cells.
Respiration
Glucose
A type of sugar (made in photosynthesis).
A chain of glucose molecules used as an energy store.
Starch
Group of molecules including sugar and starch.
Carbohydrates
A chain of glucose molecules used to build cell walls.
Cellulose
Word equation for photosynthesis
Carbon dioxide + Water → Glucose + Oxygen
Yellow/brown chemical used to test for starch
Iodine
Ethanol
Alcohol - used to remove the green colour from a leaf.
Describe the chemical test for starch
Iodine tuns from brown to blue/black (if starch is present)
