Plant structure and photosynthesis
- Plant cells are organised into tissues and organs
- Plant are made of organs like stems, roots and leaves. these organs are made of tissues
- for example 1.Mesophyll tissue-this is where most of the photosynthsis in a plant occur.
- example 2: 2. xylem and phloem- they transport things like water, mineral ions and sucrose around the plant
- example 3: 3. epidermal tissue- this covers the whole plane
- Equation for Photosynthesis: carbon dioxide+ water = glucose +oxygen
- This is a worded and symbol equation
- Photosynthesis produces glucose using sunlight
- 1.Photosynthesis is the name of the process that produces 'food'
- 2.Glucose is the name of the 'food' produced by photosynthesis
- 3.Photosynthesis happens inside the chloroplast
- 4.Chloroplasts contains a green substance called chlorochyll, this absobrs light and uses its energy to convert
carbon dioxide from the air and water from the soil into glucose. Oxygen is produced as a by-product.
- 5.Photosynthesis happens in the leaves of all green plants
- There are 4 raw materials needed for photosynthesis
- 1.sunlight-beatinng down on the leaf provides the enegry for the process
- 2.Chlorophyll is contained in chloroplasts
- 3. Water- reaches the cels vis the xylem
- 4.Carbon dioxide-diffuses into the leaf
