This is called photosynthesis, which means "making through light".

Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (singular: stoma. plural: stomata)

The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf. This also allows the oxygen produced in photosynthesis to leave the leaf easily.




Carbon dioxide is present in the air we breathe, at very low concentrations. Even though it forms about .04% of the air, it is a needed factor in light-independent photosynthesis.

In higher concentrations, more carbon is incorporated into carbohydrate, therefore increasing the rate of photosynthesis in light-independent reactions.

The aim was to show that light is necessary for photosynthesis.

Each component of a chloroplast has a unique role in photosynthesis and photorespiration.

What Role Does Chlorophyll Play in Photosynthesis? | …

We have also learnt that photosynthesis is a vital process that occurs in order to create glucose and oxygen, by transforming carbon dioxide and water in the presence of light energy.

Role of light in photosynthesis? | Yahoo Answers

Introduction: "Photosynthesis is the conversion of light energy to chemical energy that is stored in glucose or other organic compounds; it occurs in plants, algae, and certain prokaryotes" (Campbell, G-16).

Photosynthesis need light to work, so light therefore should speed up the rate of photosynthesis.

Light Absorption for Photosynthesis

Drawing upon recent work with photosynthetic bacteria, evidenceis presented as to how the carotenoids are organized within bothportions of the photosynthetic unit (the light harvesting antenna andthe reaction centre) and how they discharge both their functions.

What role does the sun play in photosynthesis? | Yahoo Answers

They serve as accessory light harvesting pigments,extending the range of wavelengths over which light can drivephotosynthesis, and they act to protect the chlorophyllous pigments fromthe harmful photodestructive reaction which occurs in the presence ofoxygen.

What role does the sun play in photosynthesis? | Yahoo …

LEDs were developed - they were required to be compatible with the photosynthesis and light-signaling requirements of plants: wavelength and fluence.
types of artificial lighting available for growing plants
LEDs ability to mimic natural light
potential for manipulating the plants metabolism

LED lights
but....
fluorescent lights are not stable over a long period of time
require additional light sources to help maintain the photon fluence necessary for high productivity
but...
Can't be placed near the plants because they have a high operating temperature
Can effect the spectral distribution due to a change of input of power
limits their use and innovation
Lettuce and Red LED Lights
Lettuce that was grown under a red LED light showed primary embryo leaves that were larger than normal.

Photosynthesis requires the following resources; Carbon Dioxide, Water and light.

What is the role of H2O in photosynthesis

Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight.

Aim: To see if raising the light intensity increases the rate of photosynthesis.

Importance of Light in Photosynthesis


“When the plants are exposed to light, chloroplast differentiation involves the accumulation of proteins, lipids and photosynthetic pigments”
beneficial because
high fluence
high photosynthetically active radiations
HID lights are used in greenhouses and plant growth rooms
beneficial because
fluorescent lights enhance blue and red spectra
fluorescent lights are used in growth rooms
Predicted to replace fluorescent and HID lamps in garden cultivation and management, it will revolutionize controlled growth environments
beneficial because
LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.
can use pulse lighting
LED LIGHTS
White LED lights present a lag phase in the Chlorophyll accumulation, but that is eliminated with using blue LED lights.

What Is the Role of Carotenoids in Photosynthesis? | …

Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase.
