How is a pineapple adapted to reduce water loss?

How is a pineapple adapted to reduce water loss?

Trichomes (“leaf hairs”) In pineapple the trichomes are multi-cellular, mushroom-shaped scaly hairs that surround the stomata and help reduce water loss from the plants.

What is the special structure of pineapple?

Pineapple is a rosette plant with fleshy, overlapping leaves, sometimes with spiny margins, and an extensive root system. The leaves store water absorbed by specialized hairs on their clasping bases. The fruit, which is crowned by a cluster of leaves, is sweet and succulent when ripe.

How do pineapples protect themselves?

Fresh pineapple contains an enzyme called bromelain, which breaks down proteins. Once you swallow the pineapple, your stomach has what it needs to protect itself from bromelain, so fear it not!

What are the characteristics of pineapple?

75-1.5 m) high with a spread of 3 to 4 ft (. 9-1.2 m); a very short, stout stem and a rosette of waxy, straplike leaves, long-pointed, 20 to 72 in (50-180cm) 1ong; usually needle tipped and generally bearing sharp, upcurved spines on the margins.

Why does pineapple tolerate drought?

This is because CAM photosynthesis allows pineapples to close their pores during the day and open them at night. As a result the plants lose very little moisture through their leaves when the Sun is out, making them extremely resilient in hot and arid climates.

Is pineapple a c4 or Cam?

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.

What is the habitat of pineapple?

Ananas comosus are a tropical plant, often grown between 30° North and South latitude. Depending on the growth environment, plant growth and fruit size vary greatly. Soil: Pineapples have the ability to grow in many different soils as long as there is drainage and aeration.

How cold can pineapple tolerate?

Cool and Freezing Temperatures. Pineapple plants do not tolerate freezing temperatures below 28°F (-2.0°C), and temperatures below 60°F (15.5°C) and above 90°F (32°C) may slow plant growth.

How old is the pineapple?

Precolonial cultivation Little is known about its domestication, but it spread as a crop throughout South America. Archaeological evidence of cultivation/use is found as far back as 1200 – 800 BC (3200-2800 BP) in Peru and 200BC – AD700 (2200-1300 BP) in Mexico, where it was cultivated by the Mayas and the Aztecs.

Are pineapples drought resistant?

Pineapples are one of the most popular crops in the world. Not only are pineapples wildly popular, but they are also one of the world’s most drought resistant crops thanks to a unique type of photosynthesis known as “crassulacean acid metabolism” (CAM). Ultimately, pineapples use 80% less water than most other plants.

Are pineapple plants drought tolerant?

Pineapples are fairly drought tolerant and can thrive with very little water.

How are pineapples adapted to live in the wild?

Adaptation. There are many restrictions that the pineapple plant must overcome in order to survive in the wild. They live in moderately warm areas (16-30 degrees Celsius).Three important limitations are that it cannot tolerate frost, it is intolerant of temperatures higher than 40° Celsius (sun also causes sunburn to the plant),…

How does CAM work in a pineapple plant?

CAM photosynthesis: 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?

What do you mean by physiological adaptation of animals?

What are physiological adaptations of animals? A physiological adaptation refers to the metabolic or physiologic adjustment within the cell, or tissues, of an organism in response to an environmental stimulus resulting in the improved ability of that organism to cope with its changing environment.

How are the leaves on a pineapple plant arranged?

Pineapple leaves – long, trough-shaped, tapered from base to tip, and approaching horizontal – are arranged spirally around the stump. This plant shape allows for maximum sunlight interception, and highly efficient gathering and movement of rain to the plant’s stem and root system.
