Biology OCR flashcards, both year 1 (AS) and year 2 (A-Level) with information taken directly from the textbook. Since I use it myself, I will update cards regularly to ensure efficient recall.
| Front | What are circulatory systems responsible for? |
| Back | - Carrying gases, nutrients, waste products and hormones around the organism. |
| Front | Describe the process of leaf abscission in response to falling light levels and temperature. (2) |
| Back | Falling light levels lead to decreased auxin concentrations, triggering the production of ethene.This initiates gene switching in the abscission zone, leading to the production of enzymes that weaken the cell walls and eventually result in leaf separation. |
| Front | What monomers is lactose made-up of? |
| Back | - Glucose + Galactose |
