konstantin123 [22]

Answer:

The <u>stroma</u> within the chloroplast

<u />

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- <u>including CO2 fixation.</u>

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 generally happens to the number of leaves as the leaf surface area decreases?
likoan [24]

As the leaf surface area decreases ; Number of leaves increase inmost plants.

As the leaf surface area increases, the rate of transpiration increases as well because leaves with large surface areas have bigger stomata. also the smaller the leave surface area of a plant/tree the denser the leaves the plants/tree will have.

Trees with tiny leaves tend to have a lot of leaves because of the decrease transpiration rate occurring in the leaves of the plants .

Hence we can conclude that what generally happens to the number of leaves as leaf surface area decrease is number of leaves increases in most plants.
