Ranked from low (6.9) to high (9.1) pH from left to right
A malfunctioning colorimeter could cause inaccuracy light absorbency/ pH values

Similarly an indicator color guide is not 100% accurate and precise to compare to the color of the CO2 indicator resulting in slightly skewed data.
If temperature was the sole factor altered in the conditions of the algae beads for photosynthesis and cellular respiration, then room temperature will be most optimal for photosynthesis to occur
This is because certain enzymes will not work as efficiently in a colder environment and could denature in a hotter environment
We predict that the algae at room temperature will have the greatest rate of photosynthesis, then the 35 degree algae, and lastly the 45 degree algae
The glucose used in respiration to make ATP is formed during photosynthesis
The glucose turns back into CO2, which is used in photosynthesis
Water is broken down to form oxygen during photosynthesis, while during cellular respiration, oxygen is combined with hydrogen to form water

In the algae, photosynthesis occurs in chloroplast while cellular respiration occurs in the cytoplasm and mitochondria
The breakdown of food molecules occurs in the cytoplasm
In the mitochondria, the high energy is released

Purpose
The purpose of this lab was to investigate the traits of Scenedesmus Obliquus under the microscope.

Lab 4: Photosynthesis and Chromatography of Spinach Leaves

Different colors of light changed to see how each color effects the photosynthetic rate.

These "Keep It Fresh" worksheets are designed to support pie-chart drawing skills. Each worksheet displays a data table reflecting some real-world context. The student is asked to summarize the data in the form of a pie chart. Students may either draw a pie chart on the printed circle (pre-ruled with 100 tick marks, each corresponding to 1%) or paste a chart they have created using technology. An answer key is included.

Lesson Plan | Photosynthesis Seen From Space

Red will have a very high photosynthetic rate
as even though it has the longest wavelength and therefore carries the
least energy it will be greatly absorbed so a lot of the light energy
will be used rater than reflected.

Water is formed from oxygen

The results validate the hypothesis
By increasing the temperature, from room temperature, it slows down the rate of photosynthesis.
Why does the rate of photosynthesis slow down?
The increased temperature that was introduced has the effect of denaturing the enzymes found in the algae.

Enzymes are a vital part of photosynthesis as ATP synthase, the ETCs and both Photosystems are the major components that carryout this process.
If the enzymes are denatured, they will not function properly, leading to a decreased rate of photosynthesis
If the increased temperature were to continue?
The room temperature environment was optimal for the algae to photosynthesize in, therefore live in.
Since photosynthesis provides the glucose that will be broken down, then lower rates of this process will lead to lower amounts of glucose to be converted into chemical energy in respiration.

Your Data Tables and Graphs will be part of your FINAL LAB REPORT

The purpose of this lab is to determine the affects of varying temperatures on the rates of photosynthesis in eukaryotic microalgae (Scenedesmus obliquus).
Purpose
Graphs/Tables
Pictures
Coenobia cells were present.

They absorb red and blue wavelengths of light and reflect green and yellow wavelengths.
Background
Floating Leaf Disk Assay Lab
If a fluorescent light is covered in red cellophane, then photosynthesis will happen at the quickest rate, and leaf disks will float to the top of a baking soda solution quickly due to oxygen production.

two data charts and four graphs were obtained.

The color to have the least
photosynthetic rate will be green as although it has quiet a short
wavelength so a lot of energy it will be reflected by the plant and
not absorbed.
