II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen and glucose.

Answer:

That's correct! Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. Water is a crucial component of photosynthesis. Here's a breakdown of the process you mentioned:

Water Absorption: Plants absorb water from the soil through their roots. Water is transported from the roots to the leaves through specialized tissues called xylem.

Photosynthesis in Leaves: Within the leaves, specialized structures called chloroplasts contain a pigment called chlorophyll, which captures light energy from the sun.

Carbon Dioxide Uptake: Carbon dioxide (CO2) from the atmosphere enters the leaves through tiny pores called stomata. These openings also allow water vapour to exit the plant in a process known as transpiration.

Photosynthetic Reactions: In the presence of light energy, water molecules in the chloroplasts undergo a process called photolysis. This means they are broken apart into hydrogen ions (H+), electrons (e-), and oxygen (O2). The released oxygen is a byproduct of photosynthesis and is released into the atmosphere.

Formation of Glucose: The hydrogen ions and electrons produced during photolysis are used in a series of chemical reactions known as the Calvin cycle. Within the chloroplasts, carbon dioxide (CO2) combines with the hydrogen ions and electrons to form glucose (C6H12O6).

Other Uses of Glucose: Glucose serves as the primary source of energy for the plant. It is used for various metabolic processes, growth, and the production of other organic compounds needed by the plant.

Overall, photosynthesis is a vital process for plants as it allows them to convert light energy, water, and carbon dioxide into oxygen and glucose, which are essential for their survival and growth.

hey hope that helps, have a great rest of the day :D
