My brother has face full of freckles. But since like three months ago I discovered new freckles, around my eyes and nose, that are really subtle but they are getting more visible with time. I just have some of them, really prominent on my face. Succulent plants like cacti have leaves that are thick and full of moisture and can also have a waxy coating to reduce evaporation.Hey there! I've never got seasonal freckles. The word crassulacean comes from the Latin word crassus which means “thick.” There are over 16,000 species of CAM plants on Earth including cacti, sedum, jade, orchids and agave. Plants that use crassulacean acid metabolism, also known as CAM plants, are succulents that are efficient at storing water due to the dry and arid climates they live in. The image above shows the C4 carbon fixation pathway. C4 plants include corn, sugar cane, millet, sorghum, pineapple, daisies and cabbage. Bundle sheath cells are part of the Kranz leaf anatomy that is characteristic of C4 plants.Ībout 3% or 7,600 species of plants use the C4 pathway, about 85% of which are angiosperms (flowering plants). The malate and aspartate molecules release the carbon dioxide in the chloroplasts of the bundle sheath cells and the Calvin Cycle begins. The oxygen content inside bundle sheath cells is very low, so the RuBisCO enzymes are less likely to catalyze oxidation reactions and waste carbon molecules. The carbon dioxide that is taken in by the plant is moved to bundle sheath cells by the malic acid or aspartic acid molecules (at this point the molecules are called malate and aspartate). C4 has one step in the pathway before the Calvin Cycle which reduces the amount of carbon that is lost in the overall process. It wasn’t until the 1960s that scientists discovered the C4 pathway while studying sugar cane. The C4 process is also known as the Hatch-Slack pathway and is named for the 4-carbon intermediate molecules that are produced, malic acid or aspartic acid. The image above shows the C3 carbon fixation pathway also known as the Calvin Cycle, used my many types of plants. Some common C3 plant species are spinach, peanuts, cotton, wheat, rice, barley and most trees and grasses. The carbon fixation pathways used by C4 and CAM plants have added steps to help concentrate and reduce the loss of carbon during the process. The result is about a 25% reduction in the amount of carbon that is fixed by the plant and released back into the atmosphere as carbon dioxide. During the one-step process, the enzyme RuBisCO (ribulose bisphosphate carboxylase/oxygenase) causes an oxidation reaction in which some of the energy used in photosynthesis is lost in a process known as photorespiration. About 85% of the plants on Earth use the C3 pathway to fix carbon via the Calvin Cycle. The C3 pathway gets its name from the first molecule produced in the cycle (a 3-carbon molecule) called 3-phosphoglyceric acid. Tropical, elevated daytime temperatures, drought
