C4 plants are mostly concentrated in monocotyledonous Gramineae, accounting for about 75% of the total C4 plants, followed by Cyperaceae. There are fewer C4 plants in dicotyledonous plants, which are mostly distributed in more than ten families such as Chenopodiaceae, Euphorbiaceae, Amaranthaceae and Compositae. No C4 plants have been found in leguminous plants that can fix nitrogen, and no C4 plants have been found in Cruciferae, Rosaceae, Solanaceae and Cucurbitaceae, so as long as they belong to these five families, they can be said to be C3 plants. 3J
