Study Notes

  • The root is the part of the plant located under the soil.
  • Roots functions include providing stability and absorbing water and minerals.

Types of Roots

  • There are two main types of roots: tap root and fibrous root.
  • Tap roots are typically found in large trees and shrubs.
  • Fibrous roots are commonly found in herbs.

Relation Between Leaves and Roots

  • Leaf venation and root type are related in plants.
  • Plants with fibrous roots tend to have parallel venation in their leaves.
  • Plants with tap roots usually leaves with reticulate venation.

Stem

  • The stem is the main structural part of the plant.
  • It provides structural support.
  • It aids in the transportation of water, minerals, and food throughout the plant.
  • Leaves and branches grow from the stem.

Flower

  • A flower is the reproductive part of a flowering plant.
  • Its primary function is reproduction.
  • Different parts of a flower have different reproductive functions.

Flower Parts

  • Sepals, petals, male stigma, and female style make up the four main parts of a flower.
