This green pigment inside plant cells captures sunlight and powers the process that creates food from carbon dioxide and water.
Difficulty: EasyThe tiny openings on leaf surfaces that open and close to allow gases in and out during food production and breathing.
Difficulty: MediumIn Brassicaceae, the diploid parent's genotype determines if SCR/SP11 pollen coat proteins are recognized by SRK receptors, causing rejection before germination.
Difficulty: HardThe flat, typically green organ where most of a plant's food-making process occurs through gas exchange with the atmosphere.
Difficulty: EasyA horizontal underground stem that grows sideways and sends up new shoots, allowing plants like ginger and iris to spread.
Difficulty: MediumS-RNases degrade growing tubes when the grain's own S-allele matches the pistil, a rejection system used by Solanaceae, Rosaceae, and Plantaginaceae.
Difficulty: HardThe sticky powder produced by flowers that must reach the female part of a plant for seeds to develop.
Difficulty: EasyThe condition where a single plant produces both male and female flowers separately, as seen in corn and squash plants.
Difficulty: Medium
