GIVE ME A "PICTURES" OR DRAWING THAT DESCRIBE THAT PROCESS ( I HOPE U GET IT HUHU) 1. They help to minimize the photorespiration and also help to fix the carbon dioxide. = FIND A PICTURE THAT DESCRIBE THE ABOVE OR DRAW IT. 2. C4 plants help to minimize the photorespiration by performing the CO2 fixation and Calvin cycle in different cell types = FIND A PICTURE THAT DESCRIBE THE ABOVE OR DRAW IT. 3. Whereas CAM plants also help to minimize the photorespiration by separating these steps between night and day. = FIND A PICTURE THAT DESCRIBE THE ABOVE OR DRAW IT. 4. Hence the main function performed by the C4 and CAM plants are the carbon dioxide fixation and to minimize the photorespiration. = FIND A PICTURE THAT DESCRIBE THE ABOVE OR DRAW IT. PS : I JUST NEED PICTURES OR DRAWING FROM YOU, NOT WRITTEN ANSWER THANK YOU ( I HOPE YOU KNOW WHAT I MEAN HUHU )

Reflected light refers to those wavelengths of light tha of the chlorophyll and not be absorbed. During the fall months, when the air temperature is significantly colder than the summer months that loose their leaves) will change color from green to red, orange, yellow or brown. This observ the graph, suggests that Chlorophyl a and b change their behavior and absorb green light and reflect the other col Less sugar is being made in the leaves, therefore less green light is being reflected. The light from the sun does not contain green wavelengths during the falls season. Chlorophyll a and b will denature and no longer be present in the leaves during the fall m Previous…

Name: How Do Chloroplasts Capture Energy from the Sun? Plant cells and some algae contain an organelle called the chloroplast. The chloroplast allows plants to harvest energy from sunlight, a process known as photosynthesis. Specialized pigments in the chloroplast absorb sunlight and use this energy to combine carbon dioxide and water to make glucose and oxygen. The complete reaction is: 6CO2 + 6H,0 → C;H12O6 + 602 9, Raw Materials (Reactants) CO, = carbon dioxide H,O = water Products CH,,O6 = glucose О, 3 охудеn Plant cells can use this process to manufacture glucose, a simple sugar. Some of the glucose is used immediately for cellular respiration, where it is converted to a high energy compound called ATP. You might recall from studies of the cell, that the process of creating ATP occurs in the mitochondria. Glucose that is not used right away is packaged as carbohydrates or fats and then stored in the roots, seeds, and fruits. All autotrophs can make their own food in this way,…
