This tutorial introduces photosynthesis
Cytoplasm: provides the platform for most chemical processes, controlled by enzymes.
Cell membrane: acts as a barrier, controlling the movement of substances into and out of the cell.
The figure illustrates how closely photosynthesis and respiration are linked. As you can see, thanks to these two life-sustaining processes, plants and animals depend on each other to survive.

Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.
Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.
Cellular Respiration and Photosynthesis
We punched out ten equal pieces of each plant and put them into small cups filled equally with bicarbonate solution and waited for them to rise to the top, testing its rate of photosynthesis.
Kale performed photosynthesis the fastest in only 17 min with total pigment distance at 43mm.
Spinach performed photosynthesis the second fastest in 24 min with total pigment distance at 55mm
Cabbage performed photosynthesis the slowest at 25 min with total pigment distance at 0mm.
Kale had a lower level of pigmentation but a faster rate of photosynthesis.

Photosynthesis- Ideas for Teaching, Resources for …
The many steps it takes to figure out the pigment levels of the chosen plants on photosynthesis rates makes this experiment interesting.
To do this lab, we tested the pigments in the following five leaves: Lettuce, Cabbage (green), Red cabbage, Spinach, and Kale.
We applied pressure with a quarter onto the leaves to leave a pigment trail onto chromatography slips.
To improve what we did we could test more plants, test the red cabbage for a longer period of time, and to discover another way to test the lettuce for its photosynthesis rate.

People should care that this was investigated because they could use this information to then plant plants with the optimum pigment level to have the most efficient photosynthesis rates.
Cell Processes: Photosynthesis & Cellular Respiration
Respiration occurs in your cells and is fueled by the oxygen you inhale. The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.
Big Ideas Cellular Respiration and Photosynthesis
Respiration consists of a complicated series of chemical reactions. In the first stage, glucose is oxidized, and the chemical potential energy of its bonds is transferred to the chemical potential bonds of an ATP molecule. The ATP molecule can then be transported throughout the cell where its stored energy is used to complete various tasks within the cell. This process releases carbon dioxide gas and water.
How are Cellular Respiration and Photosynthesis Related?
Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.
4 Answers - What is the main function of photosynthesis?
According to NASA, of all the sunlight that reaches earth, only about 48 percent of it hits the surface and only a portion of that is captured through photosynthesis. The rest is reflected back by earth’s atmosphere or absorbed by the atmosphere.
