🔑Concepts
A plant is divided into two main systems: the Root System (parts below the soil) and the Shoot System (parts above the soil).
Roots serve two primary functions: anchoring the plant firmly in the soil and absorbing water and minerals. There are two types: Taproot (one main root) and Fibrous root (a cluster of thin roots).
The Stem acts as the plant's support system and transport hub. It carries water from the roots to the leaves and food from the leaves to the rest of the plant.
The Leaf is known as the 'Kitchen of the Plant'. It contains a green pigment called Chlorophyll which helps trap sunlight to make food.
Photosynthesis is the process by which green leaves prepare food using (Carbon Dioxide), water, and sunlight.
Stomata are tiny pores located on the underside of leaves used for the exchange of gases like and .
Flowers are the reproductive parts that eventually turn into fruits. Fruits protect the Seeds, which can grow into new plants.
📐Formulae
💡Examples
Problem 1:
Identify the type of root found in a Grass plant versus a Bean plant.
Solution:
Grass has Fibrous roots, while a Bean plant has a Taproot.
Explanation:
Grass roots grow in a bunch from the base of the stem (Fibrous), whereas Bean plants have one thick primary root (Taproot) with smaller branches.
Problem 2:
A young sunflower plant is tall. After a week of heavy rain and sunlight, it grows another . What is its new height?
Solution:
The new height is .
Explanation:
To find the total height, we add the initial height to the growth using vertical addition.
Problem 3:
Which gas is taken in by the leaves during the day for food preparation?
Solution:
Carbon Dioxide ()
Explanation:
Leaves take in from the atmosphere through the stomata to perform photosynthesis.
