[carnivorous plants] characteristics and species of carnivorous plants

Carnivorous plants are mostly green plants, which can decompose the captured animals. next, let's learn about carnivorous plants.

Overview of carnivorous plants

About 400 species of carnivorous plants are known. Most carnivorous plants grow in moist wasteland, acid marsh, tree marsh, mud bank and other environments where water is rich and soil acidity is deficient in nitrogen. Whether aquatic, terrestrial or amphibious, carnivorous plants have similar ecological characteristics. Most carnivorous plants are perennial herbs, no more than 30 cm tall, often only 10 to 15 m tall. Each species is up to 1 meter long, and the smallest can be hidden in mosses in water moss swamps. Some carnivorous plants are found almost all over the world.

Plants absorb water and minerals through their roots, carbon dioxide from their leaves, and then convert carbon dioxide, water and minerals into carbohydrates and other organic compounds through photosynthesis promoted by sunlight. Insectivorous plants that use adhesion to catch insects use smell to attract insects. Felt moss, rainbow grass, and insect traps can give off a special smell, but these smells are usually too trace to be easily smelled.

The classification of carnivorous plants is constantly changing, and in the Cronquist system, based on its radially symmetrical flowers and unique insect traps, the family Gymnoliaceae and the pitcher plant family are classified as pitcher plants. A family of pitcher grasses placed in the order Coleoptera or Coleoptera. Saxifragaceae, Tripterygiaceae and Insecticidae are classified as Saxifraga. The family Cerambycidae was classified into the order Ginseng, and then merged into the order labiformes. Today I will briefly list a few common carnivorous plants to introduce.

Insectivorous plants have five basic mechanisms of catching insects.

(1) A cage or bottle trap containing digestive enzymes or bacterial digestive juices.

(2) a mucus trap covered with sticky droplets.

(3) clamp trap that closes quickly.

(4) A cystic trap that can create a vacuum and inhale prey.

(5) Lobster cage traps with inward-extending hair whiskers that force prey into digestive organs.

These traps are divided into active traps and passive traps, depending on whether they help catch prey. For example, Tripterygium plants secrete mucus, but their leaves cannot curl toward their prey, so the traps of Tripterygium are passive traps. On the contrary, the leaves of Castanopsis thunbergii roll up their prey by growing rapidly. This rapid elongation is achieved through cell division, not cell elongation. Therefore, the insect trap of Castanopsis thunbergii belongs to the active trap.

Species of carnivorous plants

The main results are as follows: 1. The carnivorous plants of the genus pitcher plants are the main groups with cage traps. The pitcher plant's insect cage grows at the end of the cage vine. Pitcher plants mainly prey on insects. Individual species such as King Malay pitcher plants can prey on larger animals, such as small mammals or reptiles, but their main prey is still small insects. The two-toothed pitcher plant has two toothed spikes at the base of the lower surface of its cover. These two fangs may be used to lure insects directly above the mouth of the cage, which will accidentally fall into the cage and be drowned by digestive juice.

2. The soil bottle herbaceous carnivorous plant endemic to western Australia has a "Mokasin" shoe-shaped insect cage. The mouth of the trap is conspicuous and secretes honey. There are lips and teeth on the inner edge of the lips to prevent prey from climbing out of the cage. Insects are often attracted by the nectar and flower-like shapes and colors secreted on their lips.

3. Skinny Broji pineapple is a kind of insectivorous pineapple carnivorous plant with cage or bottle-shaped trap. Like other related individuals, the base of the banded wax paper leaves is tightly wrapped into an urn-shaped structure. This urn-shaped structure of most pineapple plants only collects Rain Water and can become a habitat for frogs, insects or nitrogen-fixing bacteria. The urn-shaped structure of the thin Brocky pineapple has been specialized into an insect trap with a waxy inner wall, in which a large number of digestive bacteria live.

4. There are more than 100 species of Castanopsis carnivora as carnivorous plants, and there are great differences among the plants in Australia. Mini thatch vegetables, such as pygmy thatch and bulb thatch, the former produce winter buds in winter, while the latter have the bulbs necessary for overdrying in summer. These species rely on insects to provide nitrogen, so they do not have the nitrate reductase that most plants use to convert nitrogen in soil into organic forms.

5. The mucous gland stalk of the carnivorous plants of the genus Corydalis is very short, and the leaves have an oily luster. Its leaves are very effective for catching small flying insects. The recovery ability of its mucus is strong. Its leaves have contact growth, including in order to prevent prey being washed away by Rain Water, the edges of the leaves will curl inward, and the leaves will form a digestible concave under the prey.

These are all the characteristics and species of carnivorous plants that I have summarized for you. I hope this article can help you. Please continue to follow us.
