Photosynthesis, plant structure, and reproduction — how plants convert light into the energy that runs every food chain. Every question comes with a written explanation of the underlying process.
Xylem moves water and minerals in one direction, upward from the roots; phloem moves sugars in whichever direction they're needed — mixing up which tissue does which job is the most common error here.
Photosynthesis takes in carbon dioxide and water and releases oxygen and glucose — writing the equation backward, as if oxygen and glucose were the inputs, reverses the entire process.
Many plants also reproduce asexually — through runners, bulbs, or cuttings — producing offspring genetically identical to the parent, without pollination or seeds at all.

What are the two main products of photosynthesis?
Which plant tissue is responsible for transporting sugars produced during photosynthesis to other parts of the plant?
A plant is placed in a sealed container in complete darkness for 24 hours, then tested for starch content in its leaves. Compared to a plant kept in normal light, what would you expect to find, and why?
Plant biology questions reward knowing the direction each process runs — which way water and sugar travel, and which molecules go in versus come out of photosynthesis.
For transport and photosynthesis questions, name the direction of movement or the reactants and products before picking an answer. Untimed practice is where that habit sticks.
Move to timed sessions once the core processes and directions are instant recall.
Pair plant biology with ecology in a mock — photosynthesis is the entry point for nearly every food chain.
