Plant pigments and photosynthesis lab

Ideally, a teacher would have no more than twenty four students to coach through this activity. A student will have prior knowledge as to the equation describing the photosynthetic process as well as having a basic understanding of the scientific method. The lab could be used in a unit on, the scientific method, a photosynthetic unit or in a unit on environmental problems global climate change and its affect on plants. Teacher and students will review the equation describing photosynthesis.

Glencoe Photosynthesis Lab "Which colors of the light spectrum are most important for plant growth?

Context for Use

Many of your tasks will be recorded in the journal which you will print out to turn in - there are 5 questions to answer in the journal, use complete, thoughtful sentences for each of these questions. Alternatively, your teacher may have printed this document for you Site 2: You already observed how light colors will affect the growth of a plant, in this simulation you can directly measure the rate of photosynthesis by counting the number of bubbles of oxygen that are released.

There are 3 other potential variables you could test with this simulation: Keep the light settings at white light you already tested colored light in the last experiment.

Choose one variable and design and experiment that would test how this factor affects the rate of photosynthesis. Remember, that when designing an experiment, you need to keep all variables constant except the one you are testing.

Collect data and write a summary of your findings that includes:Plant Pigments and Photosynthesis Lab Report Background: (Part A)Paper chromatography is a useful technique for separating and. identifying pigments and other molecules from cell extracts that contain a complex mixture of molecules.4/4(15).

Transcript of Plant Pigments and Photosynthesis Lab Hypothesis If the solvent makes content on the edge of the chromatography paper, then Chlorophyll a will .

Report Abuse Make a bulleted list of ideas that explain this phenomenon - technique for separating and identifying pigments -a solvent moves up paper by capillary action -etc. Chemically, why do pigments differ in how they separate by chromatography?
Lab 4 Plant Pigments - Plants get most of their energy from photosynthesis. Plants are autotrophs, that generate their own chemical energy from the product of the sun through photosynthesis.
Report Abuse Setting up Water Baths: To set up the water baths, we first obtained two water bath trays and taped lined paper to the bottom of them so we could read the respirators easily without making an error in the experiment.

Photosynthesis Pigment Adenosine Tri-phosphate Absorption Spectrum Cellular Respiration (plant portion), which pigment migrated the farthest? Why? This should have been carotene (yellow) because it is the most soluble in the denatured alcohol and it is the Answer Key for Chromatography Cellular Energetics Activity #6 page 2 2.

With a pencil, draw a line 2 cm from the top of the chromatography paper. Also draw a line 2 cm from the bottom. The organization of these pigments into photosynthetic pigment, which are protein complexes that harvest light and convert its energy into biochemical energy will be explained.
