  1. Pineapple is considered an 'obligate' CAM plant, using an exclusively CAM pathway during photosynthesis. Some CAM plants are able to switch between C 3 and CAM subject to changes in the environment. Pineapple is a non-climacteric fruit without the autocatalytic ethylene burst and increase in respiration
  2. The pineapple plant undergoes a special photosynthetic pathway called Crassulacean Acid Metabolism (CAM). This is a great adaptation because it allows the plant to conserve moisture. You may be asking how does this work? Well it is a relatively simple process
  3. Pineapple (Ananas comosus (L.) Merr.) is the most economically valuable crop possessing crassulacean acid metabolism (CAM), a photosynthetic carbon assimilation pathway with high water-use..
  4. CAM Plant: Pineapple CAM stands for Crassulacean acid metabolism, this is an adaptations that plants utilize. At night these plants intake CO2 through their stomata, then the CO2 is converted into organic acids that is utilized by the Calvin cycle during the day when the stomata is closed
  5. The pineapple is an example of a CAM plant. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions that allows a plant to photosynthesize during the day, but only exchange gases at night

Examples of CAM plants, besides the aforementioned cactus (family Cactaceae), are pineapple (family Bromeliaceae), agave (family Agavaceae), and even some species of Pelargonium (the geraniums). Many orchids are epiphytes and also CAM plants, as they rely on their aerial roots for water absorption. History and Discovery of CAM plants 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. This name comes from the family of plants, the Crassulaceae, in which scientists first discovered the pathway. Image credit: Crassulaceae, by Guyon Morée (CC BY 2.0) About 3% or 7,600 species of plants use the C4 pathway, about 85% of which are angiosperms (flowering plants). C4 plants include corn, sugar cane, millet, sorghum, pineapple, daisies and cabbage. The image above shows the C4 carbon fixation pathway CAM Plants Definition. CAM - short for Crassulacean Acid Metabolism - is a method of carbon fixation evolved by some plants in dry circumstances. In most plants, the stomata - which are like tiny mouths that take in oxygen all along the surfaces of their leaves - open during the day to take in CO 2 and release O 2 The pineapple has a special photosynthetic pathway called CAM (Crassulacean Acid Metabolism). This is a feature that certain plants including cacti have evolved to conserve moisture

The innovation of crassulacean acid metabolism (CAM) photosynthesis in arid and/or low CO2 conditions is a remarkable case of adaptation in flowering plants. As the most important crop that utilizes CAM photosynthesis, the genetic and genomic resources of pineapple have been developed over many year Christopher Columbus arrived in Guadeloupe in the West Indies on 4 November 1493 during his second voyage to the New World. At a Carib village, he and his sailors encountered pineapple plants and fruit, with the astonishing flavor and fragrance delighting them then and us today Pineapple makes use of a special type of photosynthesis, called crassulacean acid metabolism, or CAM, which has evolved independently in more than 10,000 plant species. Pineapple is the most.. Abstract. Pineapple (Ananas comosus (L.) Merr.) is the most economically valuable crop possessing crassulacean acid metabolism (CAM), a photosynthetic carbon assimilation pathway with high water-use efficiency, and the second most important tropical fruit. We sequenced the genomes of pineapple varieties F153 and MD2 and a wild pineapple. Pineapple is also a model plant for studying CAM photosynthesis as an adaptation for increased water-use efficiency. In CAM plants, the stomata in the leaves are closed during the day, reducing evapotranspiration, but open at night to absorb carbon dioxide (CO 2)

Pineapple Adaptation

  1. The pineapple is a herbaceous perennial, which grows to 1.0 to 1.5 m (3 ft 3 in to 4 ft 11 in) tall, although sometimes it can be taller.In appearance, the plant has a short, stocky stem with tough, waxy leaves. When creating its fruit, it usually produces up to 200 flowers, although some large-fruited cultivars can exceed this
  2. The right answer is Pineapple. Crassulacean acid metabolism (CAM) is a type of photosynthesis that allows certain chlorophyllous terrestrial plants to fix carbon. This crassulean chlorophyll assimilation metabolism concerns succulents. This metabolism is generally found in plants living under arid conditions, such as cactus or pineapple
  3. Pineapples use CAM photosynthesis. Normally plants have to open tiny holes in their leaves (called stomata) during the day to let in carbon dioxide that they use during photosynthesis. The problem they face is that when they're letting carbon-dioxide in, plants also let water out
  4. CAM plants exhibit the highest water-use efficiencies in plants which enable them to do well in water-limited environments, such as semi-arid deserts. With the exceptions of pineapple and a few agave species, such as the tequila agave, CAM plants are relatively unexploited in terms of human use for food and energy resources

They can do this because they. answer choices. fix CO2 into organic acids during the night when temperatures are cooler. fix CO2 into by combining it with RuBP in the Calvin cycle. obtain CO2 through their roots during the day The top of a pineapple can be removed from the fruit and rooted to produce a new plant. Can you plant the C4 when attacked? Yes, but if you die, you drop the C4 This means that a pineapple plant started in spring takes less time to flower and develop fruit than one planted during fall or winter. Pineapple flowers develop in the center of the rosette. Among CAM plants, cultivated pineapple (Ananas comosus) is by far the most valuable commercial species (Cushman, 2001). Adult plants of pineapple are considered a classical example of a constitutive CAM plant (Martin, 1994; Zhu et al., 1997), but little is known about the photosynthetic behavior of young individuals of this species In many CAM plants, including the crop species pineapple (Ananas comosus), the vacuole also acts as a daytime store for considerable amounts of sugars, which can represent up to 20% of leaf dry biomass (Holtum et al., 2005)

Pineapple is a favorite fruit for many people. It is tart, sweet, and tangy, and its tropical origins put us in mind of warmer climates. In moderation, it can also be a healthy treat for dogs. (a) C4 plants grow best in hot, wet environments whereas CAM plants grow best in hot, dry environments. (b) C4 plants: corn and sugar cane CAM plants: pineapple, any succulent including cacti and jade plants a) What is the main difference between the ideal environments of C4 plants and CAM plants? b) Name two C4 plants and two CAM plants Pineapple can grow on a wide range of soils but a sandy loam texture is preferred. Optimum soil pH is 4.5 to 6.5. The soil should have a low lime content. The crop is sensitive to waterlogging and therefore requires a well-drained soil with good aeration. For high production the fertilizer needs are 230 to 300 kg/ha N, 45 to 65 kg/ha P and 110. Ananas comosus (L.) Merr. var. Smooth Cayenne plants when grown in vitro under different temperature regimes developed as CAM or as C3 plants. The plants used in this study were developed from the lateral buds of the nodal etiolated stem explants cultured on Murashige and Skoog medium for 3 mo. The cultures were maintained under a 16-h photoperiod for different thermoperiods. With 28°C light. a couple of videos ago we saw that in just classic c3 photosynthesis and once again it's called c3 because the first time that carbon is fixed it's fixed into a three or the first time carbon dioxide is fixed it's fixed into a three carbon molecule but we saw the problem with c3 photosynthesis is that the enzyme that does the carbon fixation it can also react with oxygen and when oxygen.

Some members of CAM plants remains almost wholly unexplored, although this clade have been localized to the plasma membrane; it has been reported that isolated vacuoles of pineapple however, HvSUT2 from barley was immunolocalized to contain mainly glucose and fructose (Kenyon et al., 1985; the plasma membrane by Wang (2003), but to the. The mold would have to affect an area greater than 25% of the surface, not just 25% of the stem or bottom area. In the image above you can see one side of the pineapple, or 50% of its surface. If we divide the side in half, we can see how much of a surface area 25% is. Based on the USDA's scoring guideline for surface mold, the pineapple. CAM Plants. CAM stands for crassulacean acid metabolism because it was first studied in members of the plant family Crassulaceae.CAM plants also do the C 4 pathway. However, instead of segregating the C 4 and C 3 pathways in different parts of the leaf, CAM plants separate them in time instead (Table \(\PageIndex{1}\)). As a result, CAM plants do not need to open their stomata in the daytime. Corn, or maize, is a C4 plant. A c4 plant relates to a group of plants that feature 4-carbon molecules present after the first product of carbon fixation photosynthesis. In many CAM plants, including the crop species pineapple (Ananas comosus), the vacuole also acts as a daytime store for considerable amounts of sugars, which can represent up to 20% of leaf dry biomass (Holtum et al., 2005). The sugars are subsequently degraded at night to generate the 3-carbon accepto
