How can we tell that the plant is photosynthesizing?
green water plant
movement of water
bubbles production
all are correct
Why water plant is used in this experiment?
cheap
easy to find
adapted to live under water and photosynthesize
all are correct
Why is it necessary to leave the apparatus in light place?
light is not necessary for photosynthesis
Photosynthesis does not take place in absence of water
To observe the experiment clearly
In the video, why sodium-bicarbonate is used?
to keep the water clear
to supply carbon dioxide
What is the correlation between light intensity and the rate of photosynthesis?
rate of photosynthesis increases with the increase of light intensity
rate of photosynthesis decrease with the increase of light intensity
rate of photosynthesis increases with the decrease of light intensity
rate of photosynthesis is independent to light intensity
In the experiment of rate of photosynthesis, which one is the independent variable?
number of bubbles produced in one minute
light intensity
Which gas is produced during photosynthesis?

oxygen
glucose
water
How many times we should repeat an experiment?
once
at-least two times
at-least three times
Which factors affect the rate of photosynthesis?
light
temperature
oxygen
glucose
Answers
Answer:
There are numerous species of plants all over the world. Some have adapted to desert conditions while other have adapted to cold climates. There are also plants that could only survive in cool, moist areas with adequate sunlight. These differences in climatic conditions and ecosystems have resulted in different types of photosynthesis in plants. The three types of photosynthesis are C3, C4 and CAM photosynthesis.
The definition of photosynthesis and the general equation can be found under Overview of Photosynthesis.
Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration. It is important to note that not all plants photosynthesize. Some are parasites and simply attach themselves to other plants and feed from them.
