Review the key concepts, formulae, and examples before starting your quiz.
🔑Concepts
The roots anchor the plant in the soil and absorb (water) and dissolved minerals necessary for growth.
The stem provides support for the leaves and flowers and acts as a transport system for and nutrients using specialized tubes.
The leaves are the primary site for photosynthesis, where the plant captures light energy to produce glucose.
Chlorophyll is the green pigment found in leaves that absorbs light energy for the process of photosynthesis.
The flower is the reproductive part of the plant, responsible for producing pollen, seeds, and fruits.
Plants require (carbon dioxide) from the air and from the soil to create their own food.
📐Formulae
💡Examples
Problem 1:
A student removes all the leaves from a small plant. What will happen to the plant's ability to produce food?
Solution:
The plant will no longer be able to produce food because the leaves contain the chlorophyll needed for photosynthesis.
Explanation:
Photosynthesis is the process where and are converted into glucose. Without leaves, the plant cannot capture sunlight.
Problem 2:
Explain why a plant might wilt if its roots are damaged.
Solution:
The plant will wilt because it cannot absorb from the soil to maintain its structure and carry out life processes.
Explanation:
Roots are responsible for the uptake of . If they are damaged, the plant cannot replace the water lost through the leaves.
