So our fascinating journey through the forests of our region has come to an end. What do you remember and like the most?

Children's answers.

This lesson will cover the topic “Deciduous and Coniferous Trees”, which will help students learn about the two groups of trees - deciduous and coniferous. Let's consider their distinctive features.

Lesson: Deciduous and Coniferous Trees

As you know, each tree has its own distinctive features. Leaves are one of these signs. Sheet- This is one of the main plant organs that performs the function of respiration and nutrition. The leaves of trees are very diverse in shape and size.

The 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 sheet plate with pointed ends.

Rowan has a complex leaf, on the central petiole there are up to 15 small leaves.

Composite leaf and chestnut. Slightly pointed leaves are joined at the top of the main petiole.

Birch, mountain ash, oak, maple, linden are deciduous trees. They have their own distinctive features.

1) The presence of leaves.

2) In autumn, the color of the leaves changes.

3) All deciduous trees shed their foliage. 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 to be a sacred tree. The oak is about 50 meters high and has a lifespan of 500 years. But there are also centenarians for more than a thousand years. In autumn they ripen on oak trees acorns.

These are hearty and nutritious fruits. The squirrel loves to feast on acorns, and will hide it in a hollow in reserve. The forest bird, the jay, is also a lover of delicious fruits. Wild boars also rush after acorns, because they need to accumulate fat in order to survive the winter.

Our ancestors knew: a lot of acorns on an oak - by a harsh winter. Sowing wheat is necessary when the oak leaves unfold. And the oak is also considered a symbol of power and strength. The bravest warriors were awarded with oak wreaths.

People say about cowardly people: "It trembles like an aspen leaf." In fact, the aspen leaf trembles from the slightest breath of wind. This is due to the structure of the petiole ... The stalk of the aspen is very thin and long, even in calm weather, the leaves of the aspen rustle quietly... In the spring, before the leaves appear, catkins appear on the aspen. People say: "The fluff flew from the aspen, go into the forest for the aspen boletus."

These are mushrooms that love to grow under the aspen. The caps of these mushrooms resemble the autumn coloration of aspen leaves.

What tree is this riddle about?

It takes from my flower

Bee is the most delicious honey.

And everyone offends me

The thin skin is removed.

it Linden. The 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 is the inside of the 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. Conifers include spruce, pine, cedar, fir, larch. A forest consisting of conifers is called coniferous... Unlike deciduous trees, conifers do not shed their needles in the fall, therefore their other name is evergreen.

Spruce is an evergreen coniferous tree. The crown of the tree goes down to the ground, so it is dark and damp in the spruce forests. Spruce forests are called spruce forests... Spruce roots are located close to the surface of the earth. Therefore, spruce trees fall from a strong wind, forming impassable thickets and windbreaks. It looks like a spruce branch with cones. Cones are oblong.

Spruce is a very interesting and useful tree. Its wood is used to make musical instruments and paper. Conifers emit special substances, they fill the air with a pleasant aroma and purify it. How much joy the green beauty brings to the house 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 has strong roots, so strong winds are not afraid of it. Pine can also grow on rocks and ravines. It looks like a pine branch with a cone.

The pine needles are longer than those of the spruce. The needles grow on a branch two at a time. Cones are short, rounded.

There is a tree with unusual properties among conifers - this larch... Like spruce and pine, larch has needles; in autumn, larch turns yellow and sheds needles like leaves, which is why it is called larch. In the spring, young needles appear again from the buds.

If there are both coniferous and deciduous trees in the forest, such a forest is called mixed.

Trees are the lungs of our planet. By absorbing harmful substances, trees emit air and oxygen. Leaves trap fumes and soot. Trees must be protected.

In the next lesson, the topic "Autumn in plant life" will be considered. In the course of the lesson, we will learn about the most important seasonal changes that occur with almost all plants. Let's see how autumn manifests itself, and then we will find out the role of autumn in plant life.
