How Does Pondweed Affect Photosynthesis Investigation
Photosynthesis Investigation
Research Question
How does length of pondweed affect the amount of bubbles produced in 2 minutes by pondweed during the process of photosynthesis?
Independent variable: Length of pondweed (8/10/12 cm).
Dependent variables: amount of bubbles produced in 2 minutes.
Control variables:
Volume of water in the beaker (500ml),
The volume of water has to be the same every time, so when doing the experiment I need to make sure I always use these 500 ml that i have already poured into a beaker.
Distance between lamp and beaker (1cm)
This is very important to keep the same distance between the lamp and a beaker, because the amount of light can be controlled and equal every time.
Time (2min)
Changing the time affects …show more content…
Plants can produce oxygen as by-product, and people can produce carbon dioxide.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water to make oxygen. Photosynthesis takes place in leaves. The leaves are made up of very small cells. Inside these cells are tiny structures called chloroplasts. Each chloroplast contains a green chemical called chlorophyll which gives leaves their green color.
They used to absorb light energy. Photosynthesis in plants generally involves the green pigment chlorophyll and generates much oxygen as a by-product. Plants needs carbon dioxide, water, sunlight to live and make photosynthesis work.
Photosynthesis= (Carbon Dioxide + Water + Sunlight = Oxygen + Glucose)
Carbon dioxide from the air passes through small pores (holes) in the leaves. These pores are called stomata. Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves. Sunlight is absorbed by a green chemical in the leaves called …show more content…
So big plants can produce more oxygen that little ones. In my experiment I am going to take pieces of pondweed of different length, I predict that this change will increase the number of oxygen bubbles, because there will be more surface to get more light. For example, Some plants in rainforests are very tall and have giant leaves, so they can get more sunlight. In this experiment I am going to simulate all the necessary conditions for the plant to produce oxygen (and
