A plant is destarched by placing a leaf under investigation in boiling water to get rid of all the excess starch. Then place into boiling ethanol to get rid of excess chlorophyll
a leaf (plant) should be destarched before photosynthesis investigations because the starch already present in the plant may mislead the result . hence if a destarched plant is used for the experiment then the amount of starch present at the time of the experiment will be nil and affter the experiment is compleded the amount of starch present in the leaves woul give the rate of photodynthesis as starch id prepared during photosynthesis
you boil the leaf and then put it in 3cm cube of petroleum ether and then you put the leaf in a petri dish full of starch
Destarching is typically done by subjecting plant material to a series of alcohol washes, which help to remove excess starch granules. This process involves using a sequence of increasing alcohol concentrations, such as 70% ethanol followed by 95% ethanol, to gradually extract starch from the tissues. The destarched material can then be used for various purposes, such as studying the effects of reduced starch content on plant growth or analyzing the presence of other compounds in the tissue.
Destarching a potted plant is important because it helps to ensure that the plant has a sufficient supply of starch, which is a stored form of energy, available for growth and development. By removing excess starch, typically achieved by keeping the plant in the dark for a period, you can effectively assess the plant's photosynthetic capabilities and overall health. This process is crucial in experiments related to photosynthesis, as it allows for accurate observation of how the plant converts light energy into chemical energy. Additionally, it helps to prevent potential stress or nutrient imbalances in the plant.
It mean what you don't what does it mean.
Mean is the average.
What does GRI mean? What does GRI mean?
The correct usage is "what DOES it mean"
The haudensaunee mean irguios
he was a mean person who lived with mean people in a mean castle on a mean hill in a mean country in a mean continent in a mean world in a mean solar system in a mean galaxy in a mean universe in a mean dimension
No, but sometimes "average" means "mean" - when it doesn't mean median, geometric mean, or something else entirely.
