The environment creates the conditions for the habitat of various species of plants. Wild plants adapt to external conditions on their own. Cultural plants complement our diet and require regular care.
Harbowing plants: examples, differences for the world around us
- The most fragile plants with thin stems make up the first group of plants - herbs. Unpretentious and hardy plants have a short period of life.
- The main difference between grass and other groups is soft green trunk and the absence of the bark. With the beginning of the first cooling, herbs stops his growth. Grassy plants grow throughout the globe.

Consider several annual herbs:
- Shepherd's bag -grass with an interesting shape of the fruit - in the form of a shepherd's bag. Inflorescences are formed in the form of a brush and give several thousand seeds. Shepherd's bag is widely used as a folk medicine.

- Eleasil -a photophilous plant with high stems reaching 2 m. Golden flowers of perennial grass are used as a strengthening agent.
- U two -year -olds After the first year, green shoots are dying and rhizomes remain to winter. In the second year, herbs bloom and fruits are formed. After fruiting, the plants completely die off.
- Herbs of perennials Only underground rhizomes, tubers, and bulbs are left to winter. Each year, new shoots grow on the ground part. In the tropical climate, the ground part is not updated every year. One example of such a herbaceous plant is a banana.
Shrubs: examples, differences for the surrounding world
Plants with flexible trunks and a large number of branches make up the second group of plants - shrubs. Rubbed thick branches form a thick crown through which it is difficult to get in the forest. Several branches are covered with bark, each of which is the base of the shrub. The life expectancy of perennial plants is more than 10 years.
Let's get acquainted with the most popular representatives of shrubs:
- Chernokholnaya mountain ash -unpretentious shrub with dark purple berries. The number of branches of an adult plant reaches 100 m, the height of the plant up to 3 m. The berries have both useful and dangerous properties. The shrub is grown as a decorative and medicinal plant.

Semi -brushes and shrubs
Under the influence of climatic conditions, such life forms as a half -brush and shrub are formed. Semi -bust - A combination of wood and grassy plants. The height of half -bunks is no more than one and a half meters. The herbaceous shoots of half -brushes die annually and grow again in the spring. The lower, delayed part of the plant safely winter.
Semi -buckets include:

Trees: examples, differences for the surrounding world
- The largest plants make up the third group - trees. All trees have high stable trunks covered with a layer of bark. Depending on the variety of wood, the bark has its own shade and pattern. Each new year of life thickens the tree trunk, adding new ringwhich is clearly noticeable after cutting.
- Branches of different sizes diverge from the trunks and form the crown of trees. The foliage grows on the branches and the fruits ripen. The simple foliage one plate.
- In such trees as cashtan, mountain ash, ash Several leaf plates are attached to one petiole. In the spring, all trees bloom. After flowering, they are formed fruit.
- The average height of trees is about 15 m. The life expectancy of trees is from several tens to several hundred years. Wood is important in human life. In everyday life, we are surrounded by a large number of objects of their tree.
Compare the life expectancy of several types of trees:
- Rowan red - A tree with elongated sharp leaves and red tart fruits. Grows up to 10 m in height. Life expectancy is up to 100 years.
- Birch- A tree whose trunk is covered with a white bark. Grows up to 30 m in height. Life life is up to 150 years. Nourishing juice is extracted from birch.
- The ash is ordinary - Deciduous tree with dispersal branches and rare foliage. Reaches 35 m in height. Life expectancy is up to 200 years.
- Pear - A fruit tree with large fruits. Stretched up to 20 m in height. Life expectancy is up to 200 years.
- Pine - coniferous tree up to 40 m in length. Saves life for up to 300-400 years.
- Linden - woody plant with aromatic healing colors. Extended to 30-40 m in length. Life expectancy is up to 400 years.
- Oak - A plant with a powerful barrel. It grows up to 40 meters in height. Life expectancy is up to 1500 years.
All trees are divided into deciduous and coniferous. Unlike needles, the foliage reacts to temperature changes. The needles preserve its appearance both in the heat and in the cold.
