Web7 jul. 2024 · Plants “eat” sunlight and carbon dioxide to produce their own food and food for the millions of other organisms dependent on them. A molecule, chlorophyll (Chl), is crucial for this process, since it absorbs sunlight. However, the way land plants produce their food is very different from the way plants in the oceans produce their food.

The first photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen rather than water. There are three major metabolic pathways by which photosynthesis is carried out: C 3 photosynthesis, C 4 photosynthesis, and CAM … Meer weergeven The evolution of photosynthesis refers to the origin and subsequent evolution of photosynthesis, the process by which light energy is used to assemble sugars from carbon dioxide and a hydrogen and electron … Meer weergeven Several groups of animals have formed symbiotic relationships with photosynthetic algae. These are most common in corals, sponges and sea anemones.

So, let's start with the site in eukaryotic cells of photosynthesis, and that's the chloroplast. So, this is a number of cells, and you can see how many chloroplasts we could have in a typical cell, so there's a whole bunch of them. d a# g chord
