elodea plant experiment osmosis answers



Evaluation

I think that the method used in the experiment is not very accurate
because the way we measure the amount of gas produced is not very

Oxygen production is used to measure the rate of photosynthesis.

Count bubbles of oxygen gas given off by elodea to determine the rate of photosynthesis.4.

a virtual lab investigation.Photosynthesis virtual lab.

Light intensity, carbon dioxide.
Scientific Method Virtual Lab How does the amount of available light relate to the rate of photosynthesis in photosynthesis virtual lab practice.
Photosynthesis Virtual Lab Problem: If the less light intensity it is, then the rate of photosynthesis is going to decrease.

Online Student Edition.Photosynthesis Virtual Lab.

Light intensity, carbon dioxide levels, temperature.
Problem: To what extent does distance from a light source (5cm, 10cm, 15cm) affect the rate of photosynthesis (measured in bubbles / 3 min.) in Elodea water plants.
Elodea Lab Background: Today you will be working with the aquatic plant, elodea, also known as anacharis.

How does this investigation demonstrate that plants give off oxygen during  photosynthesis?

Measuring the rate of photosynthesis - Science and …

A) sunlight concentration B) temperature C) chlorophyll concentration D) carbon dioxide availability Effects of the variables and there concentrations: The amount of sunlight will decide the rate of photosynthesis as there will be a an increased rate of photosynthesis due to the increased availability of photons of light....

Variables

Input - Light intensityis to be varied by increasing and decreasing
the distance from the light source to the plant

Output - The rate of photosynthesisis to be measured by counting the
bubbles of oxygen produced by the plant every two minutes, and
therefore finding the rate of photosynthesis

Control - The amount of water available to the Elodea will stay the
same level in the 400 cm3 beaker.

The rate of photosynthesis was recorded at a range of light Intensities and conditions.

Elodea Photosynthesis Lab - Ken Pitts

You will expose Elodea samples to various light intensities, and determine the relative rates of photosynthesis by observing changes in pH.Elodea is a common aquatic plant used in aquariums.

How does the rate of photosynthesis change when sodium bicarbonate is added  to the water?

Does light intensity affect the rate of photosynthesis in Elodea ..

Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.

In this experiment we were told that we would be measuring the rate of photosynthesis.

Photosynthesis in Elodea Lab Essay

The colour of the lamp will stay the
same (yellow) as to plants Chlorophyll easily absorbs blue light,
however it does not easily absorb green or yellow light, rather it
reflects it, this decrease's the rate of photosynthesis.
