Corpse Flower: Facts About the Smelly Plant
The smell and the dark burgundy color of the corpse flower are meant to imitate a dead animal to attract these insects. This process ensures the ongoing pollination of the species. Once the flower has bloomed and pollination is complete, the flower collapses. A mixture of tiny male and female flowers grow at the base of the spadix, the central phallus-like structure, which is surrounded by the spathe, a pleated skirt-like covering that is bright green on the outside and deep maroon inside when opened.The Corpse Flower: Behind the Stink - National Geographic
If pollinated, the spadix grows into a large club-like head of orange-red seeds. Photo courtesy Tim Sharp The plant itself grows to around 10 to 15 feet 3 to 4. The plants typically can grow to a massive 8 feet 2. According to the Guinness Book of World Records, the tallest bloom was a corpse flower that measured 10 feet 2.

The scientific name of the corpse flower is Amorphophallus titanum. According to Gustavus Adolphus Collegethe name is from the Latin words amorphos without form, misshapenphallos penis and titanum giant. The corpse flower is in the Aroid subfamily of flowering plants. Relatives include the common duckweed, skunk cabbage, calla lily and Jack-in-the-pulpit. ECSU has two genotypes genetically different individuals of corpse flower.
Rafflesiaceae lacks rbcL and other plastid genes commonly used for phylogenetic inference in green plants. In fact, Molina et al. Most traditional classifications that were based entirely on morphological features considered Rafflesiaceae sensu lato in the broad sense to include nine genera, but the heterogeneity among these genera caused early workers, such as Harmsto recognize four distinct groups that were then classified as tribes still within Rafflesiaceae.
This tribal system was followed by Takhtajan et al. The first molecular phylogenetic study using DNA sequences that showed two of these tribes were not related was by Barkman et al. This study showed three genera corresponding to tribe Rafflesieae, that is, Rafflesia, Rhizanthes, and Sapria were components of the eudicot order Malpighiales.
A female was laid tiny eggs on the caterpillar. The young wasps will actually eat the caterpillar alive! In a short time, the caterpillar will be almost completely eaten and will die. When that happens, the adult wasps will fly away. In this example of parasitism, the host dies.
Most parasites, however, do not kill their hosts. If a parasite were to kill its host, the parasite would have to find a new host. Coevolution Relationships between organisms change over time.
Interactions can also change the organisms themselves. When a long-term change takes place in two species because of their close interactions with one another, the change is called coevolution. The ant and the acacia tree have a mutualistic relationship. The ants protect the tree by attacking other organisms that come near the tree.
The tree has special structures that make food for the ants. The ants and the acacia tree may have coevolved through interactions between the two species. Coevolution can take place between any organisms that live close together. But chances happen over a very long period of time. Pollination is necessary for reproduction in most plants. Flowers have changes over millions of years to attract pollinators. Pollinators such as bees, bats, and hummingbirds can be attracted to a flower because of its color, odor, or nectar.
Flowers pollinated by hummingbirds make nectar with the right amount of sugar for the bird. Hummingbirds have long beaks, which help the drink the nectar.
Some bats changed over time to have long, thin tongues and noses to help them reach the nectar in flowers.
As the bat feeds on the nectar, its nose becomes covered with pollen. The next flower it eats from will be pollinated with the pollen it is gathering from the first flower.
The long nose helps it to feed and also makes it a better pollinator. Because flowers and their pollinators have interacted so closely over millions of years, there are many examples of coevolution between them.
types of interactions
Assessment Using key Terms 1. In your own words, write a definition for the term carrying capacity. Carrying capacity is the maximum number of individuals that can live in an environment. Use each of the following terms in a separate sentence: Mutualism is when two organisms that are interacting both benefit from the relationship.
Commensalism is when one organism is helped and the other is not affected. Parasitism is when one organism is helped and the other is harmed by the relationship. Understanding Key Ideas 3. Which of the following is NOT a prey adaptation a.
Identify two things organisms compete with one another for.
Briefly describe one example of predator-prey relationship. Identify the predator and the prey. When a cat eats a mouse, the cat is the predator and the mouse is the prey. Compare coevolution with symbiosis Sample answer: Coevolution happens when a symbiotic relationship occurs over a very long period of time and changes the structure or behavior of the organisms involved in the relationship.
However, symbiosis does not always cause a change in the structure or behavior of an organism. Explain the probable relationship between the giant Rafflesia flower, which smells like rotting meat, and the carrion flies that buzz around it.
