respiration‚ photosynthesis would not be able to perform. The process of photosynthesis is able to perform its duties with the help of an organelle called chloroplast as well. Within the chloroplasts lie thylakoids‚ a membrane system that contains pigments which are used to capture light energy. Photosynthesis is also responsible for reducing carbon dioxide into glucose‚ because reducing power is present. Reducing power is made after electrons get excited in the chlorophyll molecule. To carry out

This process occurs in plants and some algae. Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. ------------------------------------------------- http://biology.clc.uc.edu/courses/bio104/photosyn.htm ------------------------------------------------- 2- Chloroplasts: are organelles found in plant cells and other

romaine lettuce had a negative rate of transmittance which would mean that there were less photosynthetic processes happening over time. Figure 2 displays that the unboiled spinach had the highest rate of transmittance by about 0.9734‚ boiled purple lettuce had the second greatest rate of transmittance. It also shows how boiled spinach and boiled romaine lettuce had decreases in rate of transmittance yet boiled purple lettuce had an increase in the

color change occurs: Combining chemicals can change the pigmentation that gives the chemicals color. A change in the pigments will cause the light to reflect differently and a color change to occur. Testing for pH is an example of a color changing reaction. The pH of the solution will change the pigment on the litmus paper or in the indicator. Acids and bases change the pigments in different ways‚ which causes the indicator to change different colors depending on the pH. A precipitate is formed:

MGC 2018 Practical write up Name: Madison Bielby Student number: a1740189 Word Count: TITLE A study using an oxygen electrode to determine the effects of varying light intensity on the rate of photosynthesis of spinach‚ Spinacia oleracea. INTRODUCTION Photosynthesis is a two-stage process‚ each with multiple reactions‚ which must work concurrently with each other in order for plant survival. The first stage of photosynthesis is the light dependent reactions which occur in the thylakoids followed

Fruit provides a dark violet color as food colorant Anthocyanins / Natural Food Colorant : Study of pigment extracted from fruits of spinach vine (B. rubra) showed good stability with a potential as a natural food color.

float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them to absorb more light‚ increasing the rate of photosynthesis. Background context: Plant leaves are known to have a spongy mesophyll layer which usually contains
