During photosynthesis, plants take in carbon dioxide (CO 2 ) and water (H 2 O) from the air and soil . ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
How do plants photosynthesize under water?
Just like plants on land, algae photosynthesize — essentially using the sun's rays to turn molecules of carbon dioxide and water into sugar and oxygen gas . Underwater, those teeny tiny oxygen bubbles rush upward. As these bubbles detach from the plant, they make a short “ping” sound, the researchers found.
What is the process of photosynthesis step by step?

What are the 3 process of photosynthesis?
The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen . (iii) Reduction of carbon dioxide to carbohydrates.
How do plants photosynthesize for kids?
Plants take in water from the soil and carbon dioxide from the air. Photosynthesis starts when chlorophyll absorbs energy from sunlight . Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest.
Why are plants green?
Plants (plus algae and certain bacteria) absorb light to make sugars, providing the plant with energy and some other useful biochemical products which the plant requires to grow successfully. ... As such, plants look green because they absorb red light most efficiently and the green light is reflected .
Can plants survive underwater?
Aquatic plants are plants that live in water. ... These plants can only live when fully immersed in water. Most macroalgae require total submersion in water for the span of its entire life. Most aquatic plants, however, have roots underwater but can only grow or flower in a partially emersed state.
Do plants grow underwater?
Submerged plants have stems and leaves that grow entirely underwater , although some may also have floating leaves. Flowers and seeds on short stems that extend above the water may also be present. ... Floating-leaf plants are rooted in the lake bottom, but their leaves and flowers float on the water surface.
Do plants produce oxygen underwater?
In aquatic environments, free-floating microscopic plants known as algae, and larger submersed plants (macrophytes), release oxygen directly into the water where it is used by animals and other organisms, including the plants themselves.
Do plants transpire?
Just as you release water vapor when you breathe, plants do, too – although the term “ transpire ” is more appropriate than “breathe.” This picture shows water vapor transpired from plant leaves after a plastic bag has been tied around the stem for about an hour.
How do plants produce oxygen?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is the first stage of photosynthesis called?
Light energy is converted to chemical energy during the first stage of photosynthesis, which involves a series of chemical reactions known as the light-dependent reactions .
Which plant is not green?
Monotropa Uniflora is also a non-green plant. It is commonly known as Indian Pipe or Ghost Plant, an utterly white plant without chlorophyll or virtually any pigment. It is a holoparasite and derives its nutrition from mycorrhizal fungi.
Do plants like green light?
Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis , but it is still useful in photosynthesis and regulates plant architecture. ... The majority of green light is useful in photosynthesis.
What is a green plant called?
Green plants are also called photoautotrophs . Photoautotrophs name is given to the green plants because the green plants do photosynthesis for their own food. The green plants have chlorophyll in their leaves.
Why can't plants live underwater?
Gases such as carbon dioxide diffuse much more slowly in water than in air. Plants that are fully submerged have greater difficulty obtaining the carbon dioxide they need. To help ameliorate this problem, underwater leaves lack a waxy coating because carbon dioxide is easier to absorb without this layer.
