12molecules of h2o used as substrate because in 12h2o
there are 24 atoms of hydrogen and it has to split to form12 atoms of hydrogen in sugar and 12 atoms in water
.
Why is water h2o needed in photosynthesis?
Water as Electron Feeder
In the process of photosynthesis,
water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon
(of carbon dioxide) to give sugar (glucose).
How does h2o Help photosynthesis?
Water is one of the reactants in photosynthesis, it
provides the hydrogen needed to form glucose (a hydrocarbon)
. Water and carbon dioxide enter the leaf through the stomata (small holes on the underside of the leaf that are controlled by gaurd cells) by diffusion.
Do plants take in oxygen?
Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that
plants also need oxygen
. … So plants need to breathe — to exchange these gases between the outside and the inside of the organism.
Where does the water in photosynthesis come from?
The carbon dioxide required for photosynthesis comes from the air. It enters leaves through the stomata . Water enters the plant through the roots, and is transported to the leaves
in the xylem
.
Does photosynthesis 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.
How is carbon dioxide used in photosynthesis?
What Is Photosynthesis? … During the process of photosynthesis, cells use carbon dioxide and energy
from the Sun to make sugar molecules and oxygen
. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
What is the main role of water in photosynthesis?
Water is one of the most essential parts of photosynthesis. Six water molecules
react with six carbon molecules to form one molecule of glucose
. … Water also creates a chemical potential across the cell membrane that results in the synthesis of ATP molecules that are required to provide energy to the plants.
Which plant is best for oxygen?
- Aloe Vera Plant. …
- Pothos Plant. …
- Spider Plant. …
- Areca Palm. …
- Snake Plant. …
- Tulsi. …
- Bamboo Plant. …
- Gerbera Daisy. The colourful flowering plant not only makes the house look beautiful but is an excellent indoor plant for oxygen.
Which plant gives oxygen 24 hours?
The Peepal tree
releases 24 hours of oxygen and determines atmospheric CO2. No tree releases oxygen at night . We also know that plants mostly produce oxygen during the day, and the process is reversed at night.
Do plants take in oxygen at night?
Adding plants to interior spaces can increase oxygen levels.At night,
photosynthesis ceases
, and plants typically respire like humans, absorbing oxygen and releasing carbon dioxide.
Is water an end product of photosynthesis?
The end product of photosynthesis are glucose, oxygen,
water
. Glucose is utilized by plants or it is stored in form of starch. Oxygen is released into environment through stomata. Water is reutilized for photosynthesis process.
What are 2 products of photosynthesis?
Photosynthesis converts carbon dioxide and water into
oxygen and glucose
.
What do plants do with extra glucose?
Glucose is used by
plants for energy and to make other substances like cellulose and starch
. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source. That's why some foods that we eat, like rice and grains, are packed with starch!
How oxygen is released during photosynthesis?
The oxygen released during photosynthesis is
from the water
. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar. The oxygen is then released into the atmosphere whereas the sugar molecules are stored for energy.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons
return through ATP synthase
to make ATP.
