Photosynthesis in Plants

This is the correct option. It is a green pigment that helps to capture the energy of sunlight for photosynthesis.

This is the correct option. Oxygen is not required for carrying out the process of photosynthesis.

This is the correct option. Carbohydrates and oxygen are the end products in the process of photosynthesis.

All of the above show photosynthesis.

Xanthophylls are yellow, orange, or red accessory pigments found in the chloroplasts of plants, which assist in photosynthesis.

Chromoplasts are a type of plastid responsible for pigment synthesis and storage in plants, providing the red, orange, and yellow colors to fruits and flowers.

Entner–Doudoroff pathway occurs only in prokaryotes. Site of photosynthesis in purple bacteria is chromatophores.

Chloroplasts contain the pigment chlorophyll, which captures light energy for photosynthesis and gives plants their green color.

Chloroplasts and mitochondria are semi-autonomous organelles that contain their own circular DNA and ribosomes, supporting the endosymbiotic theory.

These are found only in plant cells and in certain protists (e.g. Euglena). There are two main types - chromoplasts and leucoplasts. The chromoplasts contain coloured pigment and occur in the cells exposed to sunlight. The leucoplasts are colourless and occur in the cells not exposed to light. The chromoplasts having light absorbing green pigment, the chlorophyll are called chloroplasts. The chloroplasts trap the radiant energy of sunlight and transform it into chemical energy of glucose using CO2 and H20. The process is called photosynthesis.

Lightning provides the high energy required to break the strong triple bonds of atmospheric nitrogen, allowing it to react with oxygen and form nitrogen oxides that eventually reach the soil.

“photo” is the root word, which means “light”.

The major process, that brings carbon form the atmosphere, into the living world is photosynthesis, where producers take in carbon dioxide from the atmosphere, and convert it into organic compounds. Oxygen is released as a by product. Carbon fixed by the producers, enters the food chain, and is passed to herbivores, carnivores and decomposers

Cyclic photophosphorylation involves only Photosystem I (PS I). Electrons cycle back to the reaction center, generating only ATP without the production of NADPH or oxygen.
