The diagram represents part of a plant cell. Identify the name of the location in the plant cell

konstantin123 [22]

Answer:

The stroma within the chloroplast

Explanation:

Chloroplasts are membrane-bound organelles in plants. They comprise many invaginations of a plasma membrane called a thykaloid membrane. This includes chlorophyll pigments in layers called granum, whereas the internal spaces of the organelle are called lumens. Fluid surrounds the granum, and forms the stroma; here, all metabolic reactions within the chloroplast occur- including CO2 fixation.

Photosynthesis, involves the conversion of energy from photons or light particles and water, starting in the thykaloids; here, the pigments like chlorophyll, which is essential to photosynthesis, reside.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

What are the reactants and the products in this equation? 2H2 + O2 → 2H2O

Hitman42 [59]

Answer:

Reactants: hydrogen and oxygen

Products: water

Explanation:

The reactants are what goes into a reaction, i.e. what is reacting. The products are what is formed. The reactants are usually shown on the left, and the products are usually shown on the right.

We can see in this equation that hydrogen (2H2) is reacting with oxygen (O2) to form water (2H2O). Therefore the reactants are hydrogen and oxygen, and the product is water.
