How do farmers manipulate plants to increase the rate of photosynthesis?
Greenhouses allow farmers to control the conditions in which their crops are growing. The rate of photosynthesis can be increased using: Artificial lighting also allows photosynthesis to continue after daylight hours. The cost should not exceed the additional income it generates for the farmer.
How can you increase photosynthesis?
Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor – a limiting factor – becomes in short supply.
How can the rate of photosynthesis be increased in a greenhouse?
Greenhouses can have artificial light so that photosynthesis can continue beyond daylight hours, or at a higher than normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide as well as heat.
What are the four factors that affect the rate of photosynthesis?
The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
How can farmers increase the yield of crops?
What Are The Ways To Increase Crop Yield?
- Quality Of Seeds. Agricultural productivity depends on the quality of seeds with which farmers sow their fields.
- Field Productivity Zoning.
- Monitoring Crops Growth.
- Accurate Weather Prediction.
- Regular Scouting.
- Crop Protection Methods.
- Soil Testing & Its Quality.
How does photosynthesis affect farming?
It provides nutrients for the crop. Atmospheric gases: In photosynthesis, plants constantly absorb and release gases In a way that creates sugar for food. the rate of photosynthesis is very important for agriculture, if farmers increase the rate of photosynthesis this will increase the yield of the crop.
What can affect photosynthesis?
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
How can you increase the growth of a greenhouse?
Warmth and humidity promote plant growth. Plants need moisture, warmth and light to grow. A greenhouse stabilises the growing environment by buffering the ambient temperature and protecting the plants from extreme cold.
How can farmers use their knowledge of limiting factors to increase crop growth in greenhouses?
Increasing the light intensity in greenhouses will increase the growth of crop or horticultural plants. use greenhouses constructed from glass or alternative materials that enable maximum transmission of light.
What are four environmental factors that affect transpiration?
Factors affecting transpiration
- temperature.
- humidity.
- air movement.
- light intensity.
What are plant manipulation techniques?
Plant manipulation techniques are one area that can dramatically increase yield while costing the grower very little money. In order to best utilize the light energy in a grow room it may be necessary to stake, trellis, tie-down, prune, or top your plants.
What is the easiest method of plant genetic modification?
The easiest method of plant genetic modification (see Operational Definitions in Chapter 1), used by our nomadic ancestors and continuing today, is simple selection.
How can the rate of photosynthesis be increased?
The rate of photosynthesis can be increased using: Artificial lighting also allows photosynthesis to continue after daylight hours. The additional cost of providing extra heating, lighting and carbon dioxide has to be weighed against the increased crop yield and the extra income it will provide.
How do growers manage plant growth?
Some growers manipulate their plant’s growth by physically tying down the plants. The plant is usually tied to the plant container or other permanent structure around the plant. This method increases light penetration and allows less developed shoots to catch up to taller, more developed shoots.
