Plant Structure and Photosynthesis

Plant Structure and Photosynthesis

1. Plants are made up of:

   • Organs
   • Stems
   • Roots
   • Leaves
     • For example, Leaves are made up of:
       • Mesophyll Tissues
         • Where Photosynthesis in the plant occurs
       • Xylem and Phloem
         • Transports Water, Mineral ions and Sucrose around the plant
       • Epidermal Tissues
         • Covers the whole plant
   • Plants Cell are organised into tissues and organ too

2. This is the equation for Photosynthesis

3. Photosynthesis

   • Photosynthesis produces Glucose for the plant to feed
     • Produces Glucose using Sunlight
   • Happens inside the choroplasts
     • Contains green substance, Chlorophyll, which absorbs Sunligh
       • Uses the energy to convert Carbon dioxde (from the air) and Water (from the soil) into Glucose
         • Oxygen is an by-product
   • Happen in the leaves of all green plants
     • This is the main job for the leaves to do
