Photosynthesis

Ideal Conditions for Farming

most ideal way is to grow them in a greenhouse
greenhouses trap the sun's heat and make sure the temperature doesnt over exceed and become limiting
in winter - a heater may be used
in summer - shades and ventilation may be used
light is ALWAYS needed for photosynthesis, so many farmers supply artificial light as it is more reliable and still works at night
farmers may increase the level of carbon dioxide in the greenhouse
enclosing plants prevents pests or diseases, this way, the farmer can add fertilisers to the soil to provide minerals for healthy growth
although, it is costly BUT, if farmers keep the conditions right, the plants grow much faster and a good crop can be grown more often and can be sold.
by keeping the right conditions, the farmer doesnt waste or lose any money

1. Respiration:
- plants create glucose in their leaves
- they also use glucose for respiration
- this releases energy enabling them to convert the rest of the glucose into other useful substances, using them to build new cells and grow
- producing substances means they need to gather minerals from the soil as well
2. Making Cell Walls:
- glucose is converted into CELLULOSE to make strong cell walls in a rapidly growing plant
3. Making Proteins:
- Glucose is combined with nitrate ions, absorbed from the soil, making amino acids made into proteins

4. Stored in Seeds:
- Glucose is turned into lipids, fats and oils, stored in seeds
- sunflower seeds contain a lot of oil
- seeds also store starch
5. Stored as Starch:
- Glucose is turned into starch and stored in roots, stems and leaves
- they are ready to use when photosynthesis isnt happening
- starch is insoluble - better for storing
- a cell with lots of glucose would bring in lots of water and swell up
