The equation below represents a process that takes place in plants.

Name the process. (1mk)

Photosynthesis

State three conditions necessary for the process to take place. (3mks)

  1. Presence of light
  2. Carbon IV Oxide
  3. Optimum temperature
  4. Water
  5. Chlorophyll

State three ways in which leaves are adapted to carry out the process named in Above efficiency (3mks)

  1. Broad flat lamina to provide large surface area for absorption light and Carbon IV Oxide.
  2. Thin leaf for light and CO2 to pass through a short distance.
  3. Presence of stomata for efficient diffusion of Carbon IV Oxide.
  4. Transparent cuticle to allow penetration of light to cells.
  5. Veins conduct water and mineral.

What is the role of light during the light stage of photosynthesis? (1mk)

  • Light energy is absorbed by Chlorophyll and is used to split water molecules into Oxygen + Hydrogen.
  • Light energy is also converted to Chemical energy that is used in dark stage.
