TOPIC: CROP PLANT FORM.

CONTENT: i. Plant parts

ii. Functions of each plant parts.

Sub – Topic 1: Different parts of plants

Plant form refers to the shape of a plant. Flowering plants have two regions: the shoot region, which is found above the ground level and the root region which is found below the ground level.

PARTS OF A FLOWERING PLANTS

A flowering crop plant has the following parts

  • The leaves
  • The flowers
  • The branches
  • The stem
  • The roots

Flowers, leaves, branches and stem comprise the shoot region or system while the different roots comprise the root regions system.

EVALUATION

Differentiate between shoot system and root system and name their parts.

Sub – Topic 2 Functions of the parts of a plant

The leaves: The leaves of a plant perform the following functions.

  • Manufacture food through the process of photosynthesis
  • Some leaves store food e.g. onions, cabbage, waterleaf.
  • Some leaves are used for propagation e.g. Bryophyllium
  • The leaves permit air to enter leaves the plant through the stomata.
  • The leaves give the shape of the plant.

The flowers: The functions of the flowers include the following.

  • Bright scented flowers attracts insects for pollination
  • The flowers produce the fruits and seeds
  • Some plant flowers are eaten by man
  • Use for decoration/they adds beauty to the plants.
  • They release sweet odour.

The branches: The function of the branches includes the following

  • They help to hold the leaves and fruits in shape
  • Some plant branches are used for propagation.

The stem: The functions of the include:

  • They help to transfer food nutrients from the roots up to the leaves and flowers.
  • Also, it brings down the manufactured food form the leaves to other parts of the body
  • They are used for propagation e.g. cassava stem
  • It carries the branches, leaves and flower
  • Some plant stems store food e.g. yam, Irish potato and sugar cane.

The root: The functions of the roots include

  • It holds the plant firmly to the ground
  • It absorbs minerals and water from the soil.
  • Some plant roots store food e.g. cassava and carrot
  • Some plant roots are medicinal.
