Follow in the steps of van Helmont, John Woodward, Joseph Priestley and Jan Ingenhousz and discover photosynthesisIs plant growth affected by exposure to ultraviolet light?
But how does everything get there? Water and minerals first enter the plant through its root system and is then transferred up the plant via specialized vascular tissue called xylem. Eventually the water reaches the leaves where it can then be used in photosynthesis. The leaves also contain special openings called stomata that allow carbon dioxide to enter the cells to be used in photosynthesis and for oxygen to leave into the environment.
Photosynthesis in non-green colored leaves - Wikinut
I think this because the plant may use up all of the carbon dioxide (Sodium hydro carbonate) and the plant can have as much light as it needs but if it does not have any carbon dioxide it will not be able to photosynthesise....
We all know about the mode of food preparation in plants
In the cells of green leaves, photosynthesis takes place in molecules of chlorophyll. Sunlight strikes the chlorophyll, then photosynthesis takes place.
The green pigment present in the leaves helps in photosynthesis
Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun's energy and turns it into chemical energy. Not all the light energy from the sun is absorbed.
Sunlight has many different colors in it. Chlorophyll usually absorbs red and blue light from the sun and reflects green light. It's the green light reflecting that makes some leaves look green! In the fall, some plants stop producing chlorophyll and we see leaves change color. With the chlorophyll gone, the green light is not being reflected anymore!
Effect of colour of light on the rate of photosynthesis
Sugar Maples, like all plants, are photoautotrophs, meaning they produce their own food from sunlight, carbon dioxide, and water in a process called photosynthesis. By this process, plants can then produce oxygen and organic compounds (mostly sugars). Not only can the plant produce food necessary for it to survive, but it also produces vital oxygen necessary for humans and many other organisms to survive. For a Sugar Maple tree, as for most plants, the leaves are the sites of photosynthesis.
Effect of colour of light on the rate of ..
Chlorophyll is a green pigment found in leaf cells giving them their green color. These pigments can absorb light from the sun and use it for photosynthesis. Sugar Maple trees also contain other pigments called carotenoid, which are yellow/orange pigments, and anthocyanins, which are red pigments. The last two pigments are not seen in Maple Trees all times of the year, mostly because chlorophyll is highly expressed the rest of the time essentially washing out the other pigments.
