Plants' seasonal behaviors, like flowering, based on light conditions.

Light-absorbing plant pigments that detect light and control plant behavior.

Active form of phytochrome, promoting germination and branching.

Inactive form of phytochrome, inhibiting germination and promoting upward growth.

The process where plant seeds sprout.

Plant growth responses towards or away from external stimuli.

Plant growth toward light.

Critical factor for plant flowering, telling plants when to flower for certain seasons.

The time it takes for 50% of leaves to float in a water solution, indicating their loss of turgor pressure.

A detailed diagram illustrating the process of photosynthesis, including chloroplast structure, light-dependent reactions, Calvin cycle, inputs/outputs, and energy carriers.

The first stage of photosynthesis, where light energy is absorbed and converted into chemical energy (ATP and NADPH).

The second stage of photosynthesis, where carbon dioxide is converted into sugar using the energy from the light-dependent reactions.

The process of water movement through a plant and its evaporation from leaves.

Two complexes in the thylakoid membrane that capture light energy and transfer electrons.

A series of electron carriers that pass electrons from one molecule to another, releasing energy to power the production of ATP.

The accumulation of hydrogen ions (H+) in the thylakoid lumen, creating a concentration difference and driving ATP synthesis.

Specialized plant tissue that transports water and dissolved minerals from roots to leaves.

Cohesion: Water molecules sticking to each other. Adhesion: Water molecules sticking to the xylem walls. These forces create tension, pulling water up.

A force that pushes water upwards from the roots. It's weaker than transpiration pull.

The process of water droplets being released from plant leaves due to root pressure.

The potential energy of water in a system. Water moves from high Ѱw to low Ѱw.

Cells where sugars are produced (like leaves).

Cells where sugars are used or stored (like roots, fruits).
