Oxygen that is produced in photosynthesis is given off as a gas.

However, during the day, the amount of oxygen plants release as part of photosynthesis makes the amount of oxygen they consume for respiration seem negligible.

How Do Plants Use Water in Photosynthesis? | Sciencing

Assemble the equipment needed to measure the rate of photosynthesis in elodea (water plant).3.

photosynthesis, the oxygen in the atmosphere would be ..

The plants and cyanobacteria (which use water as a hydrogendonor and produce oxygen) have Photosystems I and II, whereas theless highly evolved other photosynthetic bacteria(which do notuse water as their hydgrogen donor and do not produce oxygen)have only Photosystem I.

KS3 biology Quiz on "PLANTS and PHOTOSYNTHESIS" …

Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs--organisms which make their own food using photosynthesis.


07/01/2018 · Plants use carbon dioxide to produce food

Various other living beings, including humans, are either direct, or indirect beneficiaries of photosynthesis.



Sunlight is one of the basic requirements when it comes to photosynthesis and that explains why plants don't photosynthesize at night.

Photosynthesis | Photosynthesis | Oxygen

Chloroplasts have many shapes in different species but aregenerally fusiform shaped (and much larger than mitochondria) andhave many flattened membrane-surrounded vesicles called thylakoidswhich are arranged in stacks called grana. Thesethylakoid membranes contain all of the photosynthetic pigments ofthe chloroplast and all of the enzymes required for Light Phasereactions. The fluid in the stroma surrounding the thylakoidvesicles contains most of the enzymes for Dark phase reactions.

way, plants use light from the Sun to make their own food

It covers and protects the apical (the actively growing region) of the root.
- (also called the axis) is the main support of the plant.
- the main root of some plants; the tap root extends straight down under the plant.
- a bud located at the apex (tip) of the stem.

Through a process called photosynthesis, plants use ..

In the first case, oxygen is released as a by-product, and in the second, carbon dioxide is released as a by-product.

In plants, photosynthesis only occurs in the presence of light, but respiration occurs day in and day out.

Over 90% of plants use C 3 carbon ..

At night, plants resort to respiration, wherein they use oxygen to convert sugar into energy.


In case of photosynthesis, carbon dioxide and water react in the presence of light energy derived from sunlight to produce sugar and oxygen.

It's just that plants use sugars to build their bodies as well ..

Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.
