Photosynthesis in Plants

During photosynthesis, plants take in carbon dioxide and water, and using sunlight energy, produce glucose and release oxygen. The oxygen released comes from the water molecules (H2O), not CO2. This is why plants are called oxygen factories - they replenish atmospheric oxygen.

Green plants perform photosynthesis, which uses sunlight, carbon dioxide, and water to produce glucose and oxygen. This distinguishes them from animals that primarily perform respiration.

Two large green hemispherical structures which enclose the embryonic axis is called as the cotyledons. The cotyledons may be one or two in number depending on the type of plant. The cotyledons are important because it give nutrients during the early development of the plant before starting the process of photosynthesis.

They are the layers of cells, which are loosely packed and are located just beneath the palisade mesophyll. It plays a vital role in holding the products of photosynthesis.

This is the correct option. During photosynthesis, carbon dioxide is consumed and oxygen is released by plants.

Photolysis is the splitting of water molecules in the presence of sunlight during the process of photoynthesis.

Red algae uses phycobiliproteins to carry out the process of photosynthesis.

This is the chemical formula for chlorohyll 'a'.

PEP carboxylase catalyzes the carbon dioxide fixation in the C₄ cycle to yield the 4-carbon compound oxaloacetate.

On adding sodium bicarbonate in water, there is an increase in release of carbon dioxide. This in turn increases the rate of photosynthesis.

Pineapple grows under a semi arid region. This plant accumulates carbon dioxide at night by the CAM pathway and use it during the day.

Magnesium ion is found in the centre of porphyrin ring of the chlorophyll molecule.

Photosynthesis absorbs light energy to convert CO2 and water into glucose and oxygen. Since energy is absorbed (endothermic) rather than released, this is an endothermic process requiring continuous energy input from sunlight.

Photosynthesis is an endothermic process (option B). Photosynthesis absorbs energy from sunlight to convert carbon dioxide and water into glucose and oxygen. Endothermic processes require energy input, whereas exothermic processes release energy. 'Neutral process' and 'thermostatic process' are not standard thermodynamic classifications.

Photosynthesis converts light energy (sunlight) into chemical energy stored in glucose molecules. This occurs in chloroplasts containing chlorophyll, which captures light energy to drive the synthesis of organic compounds from CO2 and water.
