Which is required for the light-dependent reactions in photosynthesis to occur?H2O
ATP
NADPH
CO2

Answers

Answer: The correct answer is- H2O ( water).

Photosynthesis is a process by which green plants and algae prepare their own food ( using CO2 and H2O) in the presence of sunlight. It is primarily divided into two phase that is light dependent and light independent phase.

During light depednent phase ( that occurs in thylakoid membrane), solar energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH.

Water is required as splitting of water ( H2O) occurs in this phase that liberates electrons ( which are passed to reaction center chlorophyll), hydrogen ions, and oxygen atom ( which combine to form oxygen molecule).

Thus, H2O is the right answer.

The light-dependent reaction in photosynthesis to occur requires H2O (water).

Further Explanation:

Photosynthesis starts with the absorption of solar or light energy by the plant pigments called chlorophyll. The activated chlorophyll molecule helps in the electron transfer from one acceptor to another forming a chain. Photosynthesis is an anabolic process. This is the process by which glucose and oxygen produce with the help of sunlight, water, and carbon dioxide. Water is a breakdown and produces an electron which requires starting the photosystem.

The first phase of photosynthesis is the light-dependent reaction in which the absorbed light is utilized to produce molecules carrying energy that is used in the second phase to form carbohydrates by reducing carbon dioxide.

The first phase occurs in the grana region of the chloroplast and involves the transport of electrons through photosystem II (PS II) followed are I (PS I). The second phase of photosynthesis is the dark reaction or the light-independent reaction happens in the stroma and utilizes the products formed during the light-dependent phase.

During which phase of meiosis does crossing over of chromosomes occur

Answers

Answer:

prophase 1 and metaphase

Explanation:

:)

Final answer:

Crossing over of chromosomes takes place in the Prophase I phase of meiosis. This process, crucial for genetic diversity, involves the exchange of genetic material between paired homologous chromosomes.

Explanation:

Crossing over of chromosomes occurs during the Prophase I phase of meiosis. This process is critical for the generation of genetic diversity as it allows the exchange of genetic material between homologous chromosomes. During crossing over, homologous chromosomes pair up and exchange segments of their DNA. This results in chromosomes that have a mix of genes from both parents, producing unique combinations of traits in offspring.
