C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
What are CAM plants and what is their advantage?
Crassulacean Acid Metabolism (CAM) has the advantage of essentially eliminating evapotranspiration through a plants stomata (water loss through gas exchange) during the day, allowing CAM plants to survive in inhospitable climates where water loss is a major limiting factor to plant growth.
Are C4 and CAM plants the same?
The main difference between C4 and CAM plants is the way they minimize water loss. C4 plants relocate the CO2 molecules to minimize photorespiration while CAM plants choose when to extract CO2 from the environment. … C4 plants are typically summer plants like corn and sugar cane.
What are the three types of CAM plants?
Examples of CAM Plants. Specific examples of CAM plants are the jade plant (Crassula argentea), Aeonium, Echeveria, Kalanchoe, and Sedum of the family Crassulaceae, pineapple (Ananas comosus), Spanish moss (Tillandsia usneoides), cacti, orchids, Agave, and wax plant (Hoya carnosa, family Apocynaceae).
Which is a CAM plant?
Crassulacean acid metabolism (CAM) is a photosynthetic adaptation to periodic water supply, occurring in plants in arid regions (e.g., cacti) or in tropical epiphytes (e.g., orchids and bromeliads). CAM plants close their stomata during the day and take up CO2 at night, when the air temperature is lower.
Do CAM plants use PEP carboxylase?
CAM plants are known for their capacity to fix carbon dioxide at night, using PEP carboxylase as the primary carboxylating enzyme and the accumulation of malate (which is made by the enzyme malate dehydrogenase) in the large vacuoles of their cells.
What is unique about CAM plants?
Some plants that are adapted to dry environments, such as cacti and pineapples, use the crassulacean acid metabolism (CAM) pathway to minimize photorespiration. In the daylight, the CAM plants do not open their stomata, but they can still photosynthesize. …
Is aloe vera a CAM plant?
The best known are the crassulacean acid metabolism (CAM) plants, particularly the species of the genera Opuntia, Agave, and a liliaceous species, Aloe vera. … Another common feature of CAM plants is succulence, characterized by cells with large vacuoles, called hydrenchyma.
What is a CAM plant examples?
CAM plants are therefore highly adapted to arid conditions. Examples of CAM plants include orchids, cactus, jade plant, etc. Compare: C3 plant, C4 plant. See also: Crassulacean acid metabolism, Calvin cycle.
Is Rice a CAM plant?
Most plants have C3 photosynthesis, eg. rice, wheat, barley and oats; tropical grasses for example are C4, sorghum, sugarcane and corn (maize); and CAM plants such as pineapple, agave and prickly pear cactus are found in very dry conditions.
Are succulents CAM plants?
CAM plants include many succulents such as Cactaceae, Agavacea, Crassulaceae, Euphorbiaceae, Liliaceae, Vitaceae (grapes), Orchidaceae and bromeliads. CAM plants take in carbon dioxide during the night hours, fixing it within the plant as an organic acid with the help of an enzyme.
Do CAM plants release oxygen at night?
Do CAM Plants Produce Oxygen in Night? There has been a lot of research and discussion on CAM plants releasing the evolved oxygen, as the stomata are closed during the daytime. Many researchers reveal that when the stomata open at night time the gas exchange along with the oxygen release at the same time.
Is spinach a CAM plant?
They include the cereal grains: wheat, rice, barley, oats. Peanuts, cotton, sugar beets, tobacco, spinach, soybeans, and most trees are C3 plants. … The class of plants called C3-C4 intermediates and the CAM plants also have better strategies than C3 plants for the avoidance of photorespiration.
Is Nerium a CAM plant?
Nerium consists of sunken stomata, it is an adaptation seen to prevent water loss by transpiration. CAM plants like Nerium are mostly succulent xerophytes and here the stomata are present in small pit-like structures.
Is Cactus a CAM plant?
Cacti utilize CAM photosynthesis, a process unique to succulents. In CAM photosynthesis, stomata open only at night when the plant is relatively cool, so less moisture is lost through transpiration.
What is the full form of Nadph?
NADPH (nicotinamide adenine dinucleotide phosphate) is a required cofactor for CYP-mediated biotransformation, and oxygen serves as a substrate.
Where are CAM plants found?
arid regions Crassulacean acid metabolism (CAM) is a photosynthetic adaptation to periodic water supply, occurring in plants in arid regions (e.g., cacti) or in tropical epiphytes (e.g., orchids and bromeliads). CAM plants close their stomata during the day and take up CO2 at night, when the air temperature is lower.
What is the full form of CAM in biology?
Crassulacean acid metabolism (CAM) is a major physiological syndrome that has evolved independently in numerous land plant lineages. CAM plants are of great ecological significance, and there is increasing interest for their water-use efficiency and drought resistance.
How do CAM plants avoid water loss?
Unlike plants in wetter environments, CAM plants absorb and store carbon dioxide through open pores in their leaves at night, when water is less likely to evaporate. During the day, the pores, also called stomata, stay closed while the plant uses sunlight to convert carbon dioxide into energy, minimizing water loss.
What do CAM plants do to avoid Photorespiration?
CAM plants Some plants that are adapted to dry environments, such as cacti and pineapples, use the crassulacean acid metabolism (CAM) pathway to minimize photorespiration. … In the daylight, the CAM plants do not open their stomata, but they can still photosynthesis.
Why do CAM plants open stomata at night?
– CAM plants are usually xerophytes which are growing in deserts. They open their stomata during night and fix atmospheric carbon into organic acids, like oxaloacetic acid and malic acid. … The opening of stomata through night time is a physiological alteration to prevent loss of water through transpiration.
What is the major advantage of the CAM pathway?
The most important benefit of CAM to the plant is the ability to leave most leaf stomata closed during the day. Plants employing CAM are most common in arid environments, where water comes at a premium.
Do CAM plants photosynthesize at night?
CAM Photosynthesis In CAM plants, stomata open at night when conditions are relatively cool and humid. PEP carboxylase is active at night, fixing inorganic carbon into C4 acids that are stored in large vacuoles.
Why are CAM plants good at conserving water?
Unlike plants in wetter environments, CAM plants absorb and store carbon dioxide through open pores in their leaves at night, when water is less likely to evaporate. During the day, the pores, also called stomata, stay closed while the plant uses sunlight to convert carbon dioxide into energy, minimizing water loss.
Why is pineapple a CAM plant?
A CAM plant such as pineapple has the unique ability to store carbon dioxide as malic acid within the plant, allowing it to fix carbon dioxide at night as malate acids, which are then released during the day.
Is Bryophyllum a CAM plant?
Bryophyllum pinnatum (Linnaeus f.) Oken is a CAM plant native to Africa and has been cultivated widely in China. … These plants of B.
Where does the cam pathway take place?
cytoplasm These pathways of carbon fixation, know as the C4 and the CAM pathways, take place in the cytoplasm of the cell. The C4 pathway is designed to efficiently fix CO2 at low concentrations and plants that use this pathway are known as C4 plants.
Are CAM plants C3 or C4?

Sorghum is the right answer because it has C4 pathway.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
