Conifers are one of the most ancient groups of plants, dating back about 300 million years. Representatives of coniferous trees: cypress, yew, cedar, fir, juniper, pine, spruce, etc. Coniferous trees grow in abundance, in one form or another, throughout to the globe, in all parts of the world. Often coniferous trees dominate other plants. The size of an adult coniferous tree can reach 100 meters in height (the tallest coniferous tree is Sequoia evergreen - 115.2 meters). In addition, representatives of coniferous trees are not only the tallest, but also the thickest - Taxodium Mexicana (11.42 meters in diameter), the oldest - Durable Pine (4700 years old) and the largest - Sequoia Dendron giant (with a volume of 1486.9 m³) representatives of the flora. In Russia, the most common are spruce, pine, fir, cedar, and juniper.

On the topic: methodological developments, presentations and notes
Presentation "Coniferous trees"
The presentation introduces students to the characteristics of coniferous trees, as well as their use on the farm. The presentation can be used in lessons on studying the surrounding world in grades 1-2....
This lesson will cover the topic “deciduous and coniferous trees”, which will help schoolchildren learn about two groups of trees - deciduous and coniferous. Let's look at them features.
Lesson: Deciduous and coniferous trees
As you know, each tree has its own distinctive characteristics. One of these signs is leaves. Sheet- This is one of the main organs of the plant, performing the functions of respiration and nutrition. The leaves of trees are very diverse in shape and size.
Birch has small carved leaves.
Linden leaves are shaped like a heart.
Oak leaves will expand at the top of the leaf.
Maple has a wide leaf plate with pointed ends.
Rowan has a complex leaf, with up to 15 small leaves on the central petiole.
Chestnut also has a complex leaf. The slightly pointed leaves meet at the apex of the main petiole.
Birch, rowan, oak, maple, linden are deciduous trees. They have their own distinctive features.
1) Presence of leaves.
2) In autumn, the color of the leaves changes.
3) All deciduous trees shed their leaves. This phenomenon is called leaf fall.
A large number of treesform a deciduous forest.
Let's get acquainted with some representatives of deciduous trees.
The most powerful tree in the forest is considered oak. Our ancestors considered oak sacred tree. The height of the oak is about 50 meters, life expectancy is 500 years. But there are also long-livers for more than a thousand years. In autumn the oaks ripen acorns.
These are hearty and nutritious fruits. The squirrel loves to eat acorns and will hide them in the hollow as a reserve. The forest bird jay is also a lover of tasty fruits. They rush for acorns and wild boars, because they need to accumulate fat to survive the winter.
Our ancestors knew: a lot of acorns on an oak tree - to harsh winter. Wheat should be sown when the oak leaves unfurl. Oak is also considered a symbol of power and strength. Oak wreaths were awarded to the bravest warriors.
People say about cowardly people: “Trembles like an aspen leaf.” In reality, an aspen leaf trembles at the slightest breath of wind. This is due to the structure of the petiole . The aspen petiole is very thin and long, even in calm weather, the aspen leaves rustle quietly. In the spring, before the leaves appear, catkins appear on the aspen. People say: “The fluff has flown from the aspen tree, go into the forest for some aspen boletus.”
These are mushrooms that love to grow under aspen trees. The caps of these mushrooms resemble the autumn color of aspen leaves.
What tree is this riddle about?
Takes from my flower
The bee has the most delicious honey.
And everyone insults me
The thin skin is removed.
This Linden. Fragrant fragrant linden flowers attract bees. And it’s not for nothing that bees produce linden honey, it has healing properties. Our ancestors went to the linden tree for bast. This inner part bark. Thin strips were removed from the tree and bast shoes were woven. Linden wood is very soft and white. Furniture, dishes and musical instruments are made from it.
The second group of trees is conifers. Needles are modified leaves. Coniferous trees include spruce, cedar pine, fir, and larch. A forest consisting of coniferous trees is called coniferous. Unlike deciduous trees, coniferous trees do not shed their needles in the fall, so their other name is evergreen.
Spruce is an evergreen coniferous tree. The crown of the tree reaches down to the ground, so the spruce forests are dark and damp. Spruce forests are called spruce forests. Spruce roots are located close to the surface of the earth. Therefore, from strong winds, spruce trees fall, forming impenetrable thickets and windfalls. This is what a spruce branch with cones looks like. The cones are oblong.
Spruce is a very interesting and useful tree. Its wood is used for manufacturing musical instruments and paper. Coniferous trees emit special substances that fill the air with a pleasant aroma and purify it. How much joy the green beauty brings to your home on New Year's Eve!
Pine is a coniferous tree. The crown of the tree is at the very top, so it is light in the pine forests. Such a forest is called pine forest. The pine tree has powerful roots, so it is not afraid of strong winds. Pine can also grow on rocks and ravines. This is what a pine branch with a cone looks like.
Pine has longer needles than spruce. Needles grow on a branch, two at a time. The cones are short, round in shape.
Among coniferous trees, there is a tree with unusual properties - this larch. Like spruce and pine, larch has needles; in the fall, larch turns yellow and sheds its needles like leaves, which is why it is called larch. In spring, young needles emerge from the buds again.
If a forest contains both coniferous and deciduous trees, such a forest is called mixed.
Trees are the lungs of our planet. By absorbing harmful substances, trees release air and oxygen. Leaves retain smoke and soot. Trees need to be protected.
The next lesson will cover the topic “Autumn in the life of plants.” During the lesson we will learn about the most important seasonal changes, which occur in almost all plants. Let's see how autumn manifests itself, and then find out the role of autumn in the life of plants.
