What are 4 main abiotic factors that affect photosynthesis?
What are 4 main abiotic factors that affect photosynthesis?
The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
What are the 7 factors that affect photosynthesis?
The environmental factors which can affect the rate of photosynthesis are carbon dioxide, light, temperature, water, oxygen, minerals, pollutants and inhibitors.
What are the biotic factors that affect plant growth?
Biotic (i.e., weeds, insects, fungi, bacteria, etc.) and abiotic factors (i.e., sunlight, temperature, rain, humidity, drought, salinity, air, soil, pollution, magnetic fields, etc.) can affect plant growth and crop yield in many different ways.
What abiotic factors affect the rate of photosynthesis?
The rate of photosynthesis in a plant can be determined by three external factors: temperature, light intensity, and available carbon dioxide concentration. In any given situation any one of these may become a limiting factor if they are below the optimal level (Alott and Mindorff).
What factors affect chloroplast?
Light is essential for the chloroplast replication which response to the light intensity. In the dark, there was little increase in chloroplast number per cell. With a light intensity of 50 lux, the increase rate of chloroplast number per cell was about half of that with 3,000 lux.
What affects photosynthesis the most?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
How are plants biotic factors?
Biotic factors involve living organisms while abiotic factors refer to non-living things. Living are things that can grow,reproduce, produce and use energy,undergo metabolism etc. and plants are definitely living, so they are always considered biotic factors.
How do plants increase photosynthesis?
A high day temperature can increase photosynthesis, especially when light and CO2 are not limiting. However, respiration also increases with temperature because plants need more energy to support the increased rate of cell division and expansion.
Which factor will decrease photosynthesis?
The major limiting factors in this process are light intensity, temperature, and carbon dioxide levels. For both light intensity and temperature, if the level is too low or too high, the rate of photosynthesis declines rapidly.
Damage caused by these biotic factors are varied such as death of the entire plant or organs, reduced root, stem, leaf or inflorescence mass, total defoliation, bores and holes on plant parts, and other marks of feeding. Consequently, what biotic factors affect plant growth? Abiotic and biotic factors affect plant growth in agricultural soil.
What factors can affect the rate of photosynthesis?
Several factors can affect the rate of photosynthesis: 1 light intensity 2 carbon dioxide concentration 3 temperature
What are the biotic and abiotic factors of an ecosystem?
Biotic factors are all of the living organisms within an ecosystem. These may be plants, animals, fungi, and any other living things. Abiotic factors are all of the non-living things in an ecosystem. If one factor is removed or changed, it can affect the entire ecosystem and all of the organisms that live there.
What is the importance of photosynthesis in plants?
Plants make food using photosynthesis. This food is important for the plants themselves and for organisms that feed on plants. Getting optimum rates of photosynthesis produces maximum plant yields. There are several ways of measuring the rate of photosynthesis in the lab. These include:
