Review the key concepts, formulae, and examples before starting your quiz.
🔑Concepts
The plant body is divided into two main parts: the Root System (below the ground) and the Shoot System (above the ground).
The Root System absorbs water () and minerals from the soil and anchors the plant firmly.
There are two main types of roots: Taproot (a single main root, e.g., Hibiscus) and Fibrous root (a cluster of thin roots, e.g., Grass).
The Stem is the main part of the Shoot System that holds the plant upright and transports and nutrients to the leaves.
Leaves are known as the 'Kitchen of the Plant' because they prepare food through a process called Photosynthesis.
Photosynthesis requires Carbon Dioxide (), water (), Sunlight, and a green pigment called Chlorophyll.
Stomata are tiny pores on the leaves used for the exchange of gases like Oxygen () and .
Flowers are the reproductive parts of a plant that eventually turn into fruits containing seeds.
Seeds contain a baby plant and food; they grow into new plants during a process called Germination.
📐Formulae
💡Examples
Problem 1:
Which part of the plant is responsible for transporting water () from the roots to the leaves?
Solution:
The Stem.
Explanation:
The stem acts like a pipeline, carrying water () and minerals absorbed by the roots to all other parts of the plant.
Problem 2:
Explain the role of in the life of a plant.
Solution:
Plants take in from the air to make food.
Explanation:
During photosynthesis, leaves combine Carbon Dioxide () and water () in the presence of sunlight to produce glucose.
Problem 3:
Identify the difference between a Taproot and a Fibrous root.
Solution:
A Taproot has one thick main root, while a Fibrous root has many thin roots of similar size.
Explanation:
Plants like carrots have a Taproot system, whereas plants like wheat or onions have a Fibrous root system.
