What are the factors affecting the Guttation in plants?
Root takes in water, generates hydrostatic pressure, pushes the water up to the xylem vessels, then to the leaves then causes guttation
Factors affecting plant distribution?
Climate (temperature, precipitation, wind...), relief (mountain ranges, basins, altitude...), soil properties (nutrients, pH, humification...). Recently, antropogenic influence is also a major factor. Ice ages also had an impact on plant distribution. Plant life that was situated to the north disappeared or moved to the south. Afterwords, plants in the south slowly began to reappear in the northern parts of Earth.
Factors affecting the concentration of nutrients in plants?
Major factors-: Light intensity: Generally, more light intensity results in swifter photosynthesis. Carbon dioxide concentration: More levels result in a bigger rate. This is usually the rate-limiting step in natural settings. Temperature: Like all chemical reactions, lower temperatures speed down the rate. However, above a certain point, high temperatures hurt the enzymes responsible for photosynthesis. There is an optimal temperature range for photosynthesis, usually around 30 °C/86 °F. Availability of water: Although water is needed as a raw material for photosynthesis, if water is short, it will cause the plant to wilt (and thereby lose its ability to capture sunlight) long yester it limits photosynthesis at the biochemical level. Availability of nutrients: On a deeper level, other factors like amount of chlorophyll, availability of nutrients (e.g. Mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis.
What are some factors which influence soil fertility?
Here are some factors that influence soil fertility;soil pH: this determines which nutrient becomes available for plant use.Presence of organic matter: organic materials have nutrients in them that need to be recycled for the next growing cycle. Increasing soil organic matter content means you are increasing the fertility of the soil.Moisture content : nutrients available in the soil for plant use are mostly found in the soil solution, not in the solid matrix. Soil with low moisture content are not very fertile.Antagonistic effect of another nutrient : the presence of certain elements in the soil can make other elements unavailable. Eg. Iron compounds always precipitate with phosphorus, and excess potassium can make magnesium unavailable.Bulk density: you don't want your soil to be compacted. Because compaction can obstruct root penetration. If the roots cannot penetrate the soil, then they can't reach the nutrients.Clay content: this factor determines the cation exchange capacity of the soil. Higher CEC means more nutrients would be temporarily reserved for when the plants need them. Low CEC means that nutrients can be easily lost by leaching off to the ground water.I hope you know the difference between soil fertility and soil productivity? it is always important to clarify the difference between the two.So, here you go..Soil fertility refers to the ability of the soil to provide plants with the nutrients they need. While soil productivity is the capability of the soil to produce maximum crop yield. So you see; a particular soil may be fertile, but not necessarily productive, due to certain factors that prevent nutrient uptake by plants.
Is water and nutrition internal or external factor in conditions of plant growth?
Photosynthetic productivity is the carbon balance of a plant over time and depends on the following external factors like light, water, nutrients, gases, temperature. Internal environmental factors include leaf age and chlorophyll content, osmotic adjustment, the presence of strong sinks, photorespiration, and plant hormones.
List 5 factors that might influence the rate of oxygen or carbon dioxide production or consumption in leaves.?
1. Light: present or absent? Amount of light. 2. Water: Drought can cause stomates to close. This cuts back on water loss but also excludes the carbon dioxide needed for photosynthesis. 3. Temperature: Within the range suitable for life metabolic processes slow with decreased temperatures and speed up with increased temperatures. 4. Mineral nutrition: Magnesium is essential for chlorophyll, Iron is essential for Ferridoxin. Deficiency of mineral nutrients causes disease-like symptoms and impedes normal processes. 5. Atmospheric Composition: Plants will die in the prolonged absence of oxygen or carbon dioxide. 6. Type of plant: there are C3, C4 and CAM plants.
What are the factors that affect translocation in plants?
pardon me for not mentioning this earlier, but if possible, please explain abit more on how they affect translocation please?: D and thanks for the first contributor to this question: D what are sink cells, by the way?i didnt get relevant results on google..
