Describe the pathway of water from the roots to the leaves.
Water moves through the phloem to reach the leaves.
Water travels from roots to leaves through root absorption, xylem transport, and evaporation.
Water is absorbed by leaves and transported to roots.
Water evaporates directly from the soil to the leaves.
What is the relationship between photosynthesis and transpiration?
Photosynthesis occurs only at night, while transpiration happens during the day.
Photosynthesis and transpiration are unrelated processes that do not affect plant health.
Photosynthesis provides the energy and oxygen needed for plant growth, while transpiration facilitates nutrient transport and cooling, both processes are essential for plant health.
Transpiration is the process of photosynthesis occurring in the roots of plants.
Explain how xylem and phloem work together in plants.
Xylem and phloem both move nutrients downward in the plant.
Xylem transports water and minerals upward from roots, while phloem distributes sugars from leaves to the rest of the plant.
Xylem carries sugars while phloem transports water.
Phloem absorbs sunlight and xylem releases oxygen.
What is the function of stomata in leaves?
To transport water
To exchange gases
To store food
To protect the plant
Which of the following best describes the function of phloem?
It transports water from the roots to the leaves.
It transports nutrients from the soil to the roots.
It transports food from the leaves to other parts of the plant.
It provides structural support to the plant.
What is the main reason why leaves are typically green?
They contain chlorophyll, which is essential for photosynthesis.
They are covered in a green waxy coating.
They reflect green light from the sun.
They absorb green light from the sun.
What is the process called when water evaporates from the leaves of a plant?
Transpiration
Photosynthesis
Respiration
Germination
