Photosynthesis requires a few main components. Mainly, Sunlight, Water and Carbon dioxide.
For this reaction, the reactants are 1) Water 2) Carbon dioxide
For water, it enters the cell by Osmosis. Water enters a cell through a partially permeable cell surface membrane.
When water enters a space through a partially permeable membrane from a high water potential to a low water potential, the process is called osmosis.
For carbon dioxide, it enters the cell through diffusion.
Diffusion involves particles moving from a region of higer concentration to a region of lower concentation. Therefore, the answer is Diffusion.
Extra knowledge: Carbon dioxide dissolves into the thin film of moisture on the surface of the spongy mesophyll layer for easy transportation to the cells involved in photosynthesis.
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today
Igneous rocks can be found In the earths surface metamorphic rocks can be found mountainous regions sedimentary rocks can be found In earths upper crust!
