Plant Transpiration and Hydrological Cycle

Flashcards covering key concepts from the lecture notes on Taveuni Island, Field Botany, the Water Cycle, Transpiration basics, and Leaf Anatomy, focusing on fill-in-the-blank questions for review.

Photosynthesis requires H2O, CO2, and _, and ultimately produces O2 and sugar.

light

_ is the process in plants where energy capture is accompanied by water loss.

Transpiration

In the hydrological cycle, the largest reservoir for water storage is the _.

Ocean

The combined flux of water from the land to the atmosphere through evaporation from the soil and transpiration from plants is referred to as _.

Evaporation, transpiration

According to the hydrological cycle diagram, the units for water storage are _.

Thousand cubic km

The small pores on the leaf surface through which gas exchange and water loss occur are called _.

stoma

The specialized cells that surround and regulate the opening and closing of a stoma are known as _.

guard cells

The waxy outer protective layer covering the epidermis of leaves, which helps prevent excessive water loss, is the _.

Cuticle

When stomata are _, a plant cannot take up CO2 or lose water via transpiration.

closed

Stomatal closure is influenced by several factors, including light, temperature, relative humidity, and _ speed.
