5 Unique Carnivorous Plants Make a Traps | Part 2

Continuation article of : 5 unique carnivorous plants5 — Plants have the characteristics of each, as well as humans. Like humans, plants also are living beings, need food to grow and proliferate. Each type of plant has a way to survive in accordance with their own kind. There are 5 kinds of strange plants studied, turned out to have a plant have unique way to make a traps. Below is a list of 5 unique carnivorous plants make a traps, complete with a mechanism to eat. Let’s see.

4. Aldrovanda vesiculosa

Aldrovanda vesiculosa, also known as water mill plant, is interesting plants without roots, carnivores, and also aquatic plants. usually eat small vertebrates, using a mechanism called a trap snap traps.

This plant is mainly composed of free-floating stems, reaching 6 – 11cm in length. Trap leaves grow along the 2-3mm grew from 5-9, in succession along the stem near the center of the plant. Trap attached to the petioles, which contain air, and assist in flotation.

This is a very fast growing plant and can reach 4-9mm per day, in some cases even generate new thread every day. As the plant grows from one end, the other end will continue dead.Perangkap basically consists of two lobes together to make the traps shut.

The openings of the trap exit point, and covered in a layer of hair trigger, which will cause the trap to clap shut down when any prey that comes too close. speed trap shut is 10 milli / sec, making it one of the fastest examples of plant movement in the animal kingdom.


5. Dionaea muscipula

Dionaea muscipula, better known as the Venus flytrap, carnivorous plants is probably the most famous, and he ate mainly on insects and arachnids. Venus flytrap is a small plant that has 4-7 leaves that grow from underground stems short. Leaves are divided into two: a heart-shaped leaf stalks are flattened and a pair of terminal lobes hinged at the midrib, forming a trap which is actually a true leaf. The surface the inside of the lobes contains red pigments and ultimately remove the mucus.

This shows lobes fast motion by putting plants close when special sensory hairs are stimulated. This plant is so advanced that can distinguish between the stimulus and the stimulus that is not living life.
Lobes close within about 0.1 / sec. they are constrained by rigid spines or protrusions such as cilia, which cover together and prevent large prey from escaping. Once the prey can not escape and the inner surface of the lobe continues to be stimulated, or gripping the edge of the lobes to grow together, sealing the trap and create a “belly” closed where digestion and absorption can occur.

That’s 2 types of meat-eaters unique plants continuation page from the list of five unique carnivorous plants | Part 1. There are another 3 of meat-eaters unique plants, on the other page: 5 unique carnivorous plants | Part 1. How to eat and how they obtain prey such as animals, different way with other plant species, which survive with sunlight and water. 5 unique carnivorous plants have their own way to make a traps.

5 Unique Carnivorous Plants Make a Traps | Part 1

5 Unique carnivorous plants make a trapsPlants have the characteristics of each, as well as humans. Like humans, plants also are living beings, need food to grow and proliferate. Each type of plant has a way to survive in accordance with their own kind. There are 5 kinds of strange plants studied, turned out to have a plant have unique way to make a traps. Below is a list of 5 unique carnivorous plants make a traps, complete with a mechanism to eat. Let’s see.

5. Pinguicula

Pinguicula, or butterworts, is a group of carnivorous plants that use a sticky substance, glandular leaves to lure, trap and digest insects. Nutrients from insects complement the mineral content of the soil is poor. There are about 80 species found throughout North and South America, Europe and Asia.

Butterwort leaves are beautiful and usually green or pink of Regional. There are two specific types of cells found on the upper side of leaf butterwort. One, known as penduncular gland, and consists of secretory cells on a single stem cell. These cells produce a mucilaginous secretion which forms visible droplets on the leaf surface, and acts like flypaper. Other cells called glands sessile. They lay on the leaf surface and produce enzymes such as amylase, esterase and protease, which helps in digestion process.

4. Drosera

Drosera, commonly known as the sundews, consisting of one of the largest genus of carnivorous plants, with at least 194 species. can be found widely spread over every continent except Antarctica. Sundews, (depending on species) can take the form of roses prostrate or erect, ranging from 1 cm to 1m high, and can live to 50 years.

Sundews glands characterized by moving tentacles, topped with sweet sticky liquid. When an insect lands on the sticky tentacles, these plants can move more toward the tentacles to trap more insects. Once trapped, small sessile glands of insects to digest and absorb nutrients that are generated, which can then be used to help growth.

3. Byblis

Byblis, or a rainbow plant, is a small genus of carnivorous plants native Australia. The name comes from the rainbow plant an attractive appearance leaves them covered with slime in the sun. Although this plant looks similar to Drosera and Drosophllum, they are not related to the similarity of species and can be distinguished by flowers with five stamens Zygomorphic curved.

The leaves have a rounded cross section, and they tend to be very elongated and tapered at the ends. Leaf surface completely covered with hair glands that release a sticky mucilaginous substance, which in turn trap small insects on the leaves or tentacles as a passive flypaper traps.

That’s 3 types of meat-eaters unique plants from the list of five unique carnivorous plants. There are still two other meat-eaters unique plants, follow the continuation of this article on the next page: 5 unique carnivorous plants | Part 2. How to eat and how they obtain prey such as animals, different way with other plant species, which survive with sunlight and water. 5 unique carnivorous plants have their own way to make a traps.

2 New Member in The Periodic Table of Elements

Periodic table that contains the chemical elements are used now grow its contents. What are two chemical elements that become a new member in the periodic table of elements? We refer to his review follows.

Periodic table has two new members, elements 114 and 116. Both are the heaviest chemical element. Element 114 has a weight of 289 atomic mass units, while the 116 has a weight of 292 atomic mass units.
Both elements have actually been found in more than 10 years – 114 was found in 1999, 116 was found in 2000. International Union of Pure and Applied Chemistry and International Union of Pure and Applied Physics just enter it now after going through various verification.

At present, 114 and 116 called ununquadium and ununhexium. However, the inventor who came from Russia proposed the name “flerovium” for 114 was taken from a nuclear physicist Georgy Flyorov. Element 116 is proposed given the name “moscovium” coming from Moscow Oblas.

These are two chemical elements that become a new member in the periodic table of chemical elements. Two new chemical elements have been through a lot of evidence to be accepted as a member of the periodic table of elements.
