Sundew plant Sundew are a kind of carnivorous plant. The leaves of sundews are covered with "tentacles". sundew is found throughout all parts of the world. Its greatest concentrations are in Australia and South Africa‚ making them the largest group of carnivorous plants. They have a long-ish head that’s parallel to the ground with small sticky red balls. The insect sticks to the balls and the head curls up to eat it. Besides those there are also some ones in which the heads are the shape of

INSECTIVOROUS PLANTS An insectivorous plant‚ also called a carnivorous plant‚ captures prey items‚ such as insects‚ spiders‚ crustaceans‚ mites‚ and protozoans‚ as a nitrogen source. Many insectivorous species live in freshwater bogs‚ where nitrogen is not present in available form‚ because the pH of the water is extremely acid. The forms of entrapment by these types of plants are modified leaves. Five basic trapping mechanisms are found in carnivorous plants. 1. Pitfall traps (pitcher plants) trap prey

Castor canadensis‚ otherwise known as the North American Beaver‚ is a keystone species on the verge of extinction. It lives in the northern regions of North America‚ specifically in Canada and the United States. Its status on the IUCN red list is endangered. This species is very beneficial‚ but is racing extinction due to people not seeing the importance it does to both humans and the ecosystem alike. The benefits of these beavers are that they prevent water floods and regulate water flow which

Period G Interspecific and Intraspecific Plant Competition Abstract A study was conducted to address the problem of interspecific and intraspecific competition among wheat and mustard plants. It was hypothesized that increasing the plant density‚ and therefore increasing intraspecific competition‚ would negatively impact the plant biomass. It was also hypothesized that interspecific competition would have a stronger negative effect on the plant biomasses. This was tested by planting varying

Genlisea Violacea is a carnivorous plant that is restricted to the areas of South America and Trinidad. (1). This species can grow when it I half or fully submerged in water. (2) They flourish best in wet habitats‚ such as marshes and swamps. (2) The top part of the trap consists of a descending stolon. (2)About midway down the stolon there is a swollen digestion chamber—the utricle--which makes the descending part of the stolon look somewhat like the neck of an ostrich that has

GROWN-UP’S ARE A DIFFERENT SPECIES Understanding grown-up’s is never easy. They hold on to things that were. They wonder what’s to come... and then they think they know everything just because they have experience! Really!! Antoine de Saint said: “Grown-ups never understand anything for themselves‚ and it’s tiresome for children to be forever explaining things to them”. For example: Have you ever seen a grown-up just after they got a new cell phone? They’re too scared to explore the menu options

deforestation keeps on happening? I strongly believe that we need to stop deforestation before it is too late‚ or else we‚ humans‚ will suffer a lot from it. It has been told that forests are our world lungs. As many of us have known‚ every green plant can do photosynthesis‚ a process of producing oxygen from carbon dioxide. If deforestation keeps on happening‚ our oxygen supply will also deplete. That’s one thing I can guarantee. It means that we won’t have enough air to breathe with and it will

PLANT RESPONSES TROPISM is a biological phenomenon‚ indicating growth or turning movement of a biological organism‚ usually a plant‚ in response to an environmental stimulus. In tropisms‚ this response is dependent on the direction of the species. The word tropism comes from the Greek trope ("to turn" or "to change"). Tropisms are usually named for the stimulus involved and may be either positive (towards the stimulus) or negative (away from the stimulus). Phototropism is the growth response

whether or not handwriting will become obsolete has gained increasing prominence in Australian media recently after the education minsters’ agreement that in 2016‚ the State wide Naplan test will be done online. In her opinion piece titled‚ “The vanishing art of handwriting”‚ a supplement magazine for a weekend paper‚ Leslie Slater expresses her concern that the growing use of technologies intended to replace traditional “pen and paper” could mean that handwriting will eventually‚ no longer be an

Invasive species have a history of damaging the ecosystems in which they are introduced. How marine invasive species interact with other stressors produce an increased negative effect on the ecosystem; usually the marine invasive species alone does not create a stressor. As more marine species are introduced into the environment‚ the magnitude of the interactions will only increase. NOAA dictates four reasons why marine invasive species are not typically thought as important stressors for the ecosystem
