Review the key concepts, formulae, and examples before starting your quiz.
🔑Concepts
Roots: These anchor the plant into the ground and absorb (water) and essential minerals from the soil.
Stem: The stem acts as a support system for the plant and transports and nutrients from the roots to the leaves.
Leaves: Known as the 'food factory' of the plant, they use sunlight, (carbon dioxide), and to produce food through a process called photosynthesis.
Flowers: These are the reproductive parts of the plant that produce seeds to create new plants.
Chlorophyll: The green pigment found in leaves that captures light energy to facilitate the production of glucose ().
📐Formulae
💡Examples
Problem 1:
Which part of the plant is responsible for absorbing from the soil?
Solution:
The Roots.
Explanation:
The roots have tiny root hairs that increase surface area to soak up and minerals effectively.
Problem 2:
What gas do plants take in from the air to make their food?
Solution:
(Carbon Dioxide).
Explanation:
During photosynthesis, leaves take in through tiny holes called stomata and release (Oxygen) as a byproduct.
Problem 3:
Why are most leaves green in color?
Solution:
Because they contain Chlorophyll.
Explanation:
Chlorophyll is a green pigment that absorbs sunlight, which is necessary for the plant to convert and into energy.
