Sometimes genes change their form in a process without a reason and it's called spontaneous mutation. Spontaneous mutations<span> occur with non-zero probability. And they occur even in an uncontaminated cell. They are characterized by the specific changes.</span>
Plants<span> do not have skeletons, but their shape is defined by the part of the </span>cell<span> called the </span>cell<span> wall. The </span>cell<span> wall is featured only in </span>plant cells<span> and is made of cellulose. Chloroplast: Chloroplast is another big </span>difference between plant<span> and </span><span>human cells. </span>

The answer is endothermic.
Endothermic reactions are reactions that need energy to form a product.
Exothermic reactions are reactions that release energy.
Photosynthesis is a process in which energy of sunlight is used to convert carbon dioxide and water into glucose and oxygen. Hence, the energy of sunlight is needed for photosynthesis. So, photosynthesis is endothermic.
