What is a good question to ask about photosynthesis?
What form of energy do cells need in order to do work? What types of organisms must obtain their food by consuming other organisms? What is the chemical equation for photosynthesis? Where is the energy used in photosynthesis obtained?
What photosynthesis Cannot occur?
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there. …
Which step in photosynthesis does not need light?
The light-independent stage, also known as the Calvin Cycle, takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light-independent reaction.
What is photosynthesis science question?
Photosynthesis is the process by which plants, algae and some bacteria use sunlight, carbon dioxide and water to prepare their food. This is a biogeochemical process in which light energy is converted into chemical energy. Photosynthesis takes place in the chloroplast.
Did you know facts about photosynthesis?
10 Facts on Photosynthesis
- The green color of leaves is due to chlorophyll.
- The two main parts of a chloroplast are the grana and stroma.
- The first stage of photosynthesis captures energy from the sun to break down water molecules.
- The second stage of photosynthesis is the Calvin cycle.
Why does photosynthesis stop at night?
The proteins involved in photosynthesis need to be ‘on’ when they have the sunlight they need to function, but need to idle, like the engine of a car at a traffic light, in the dark, when photosynthesis is not possible. This cascade thus keeps photosynthesis on standby until light is available again.
Can photosynthesis occur without water?
Water is needed for photosynthesis, the process by which a plant uses sunlight to turn water and carbon dioxide into energy! The byproduct of this process, lucky for us, is oxygen.
Why are plants green?
The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. As such, plants look green because they absorb red light most efficiently and the green light is reflected.
How do plants split CO2?
The carbon dioxide enters the leaves of the plant through small pores called stomata. The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water — known as CO2 and H2O, respectively — into their individual molecules and combines them into new products.
Why photosynthesis is called dark reaction?
Therefore the dark reaction in photosynthesis is called so because it don ot directly depend on light energy. Dark reaction of photosynthesis has distinct chemical reactions which help in the transformation of carbon dioxide and other compounds to form glucose.
What are some interesting facts about photosynthesis?
Interesting Photosynthesis Facts: In order for a plant to make its own food through the process of photosynthesis it requires three things: carbon dioxide, water, and sunlight. The veins in a plant that pull water from the soil are called xylem. Chlorophyll is the green pigment in a plant’s leaves. Chlorophyll is what traps the sun’s energy.
Why is photosynthesis important to the environment?
The photosynthesis is very important for the earth because the trees use this process in order to provide oxygen to the earth. The trees absorb the carbon dioxide present on the earth and replenish it with oxygen which is important for all the living beings in order to survive.
What are three inputs of photosynthesis?
Materials Needed for Photosynthesis Chlorophyll. Chlorophyll, the pigment in plants that makes them green, is essential to the photosynthetic process. Sunlight. The process cannot work without an energy input, and this comes from the sun. Water. As any gardener knows, plants take in water from the ground through their roots. Carbon Dioxide.
What is the test for photosynthesis?
Sunlight Necessity Test For Photosynthesis. As it is oxygen for animals, sunlight is for plants. Sunlight or the light energy released by sun is one of the factors of photosynthesis and now you’re going to test its accuracy with below scientific test. For this test, you need a plant rooted in a pot, bucket or something portable.
