LEAF IS A PART OF VICTORY. OUTER AND INNER BUNDLE SHEET. LEAF TYPES. Eromkina E.V. – teacher of biology, Municipal Educational Institution of Educational Secondary School No. 3, Volsk, Saratov region.
LEAF IS ONE OF THE MAIN BODIES OF ROSLINI, OCCUPING A BIK POSITION IN PEREMOGI. CLASS OF THE LEAF: 1 – LEAF BLAME; 2 – VEINS; 3 - petiole; 4 – SPIDS; 5 – SHEET SUBSTANCE.
VEINS - DEVELOPMENTS OF JUDICIAL TISSUE IN THE MIDDLE OF THE LEAF. STAIN THE ARKUSH WITH WATER AND MINERAL STREAMS AND TRANSFER THE LIVING STREAMS AND VYROBLENS TO THE LEAVES. INNER SHEETS
PERISTE AND PALMATE VENAL - IN THE LEAF OF DICOLODINOUS ROOPS. PARALLEL AND ARC VENALATION - THE LEAVES OF MONOCOTT ROSSINS ARE PLENTY.
STOVBCHATIY (PALISARD BALL) KLITINA. PLACE THE TOP SURFACE OF THE LEAF, MIX PLENTY OF CHLOROPLASTS. COLUMN CLITINI SKIRITS CALL SHEET COVERING SKIRITS. SPONGE CLITINI SPONGE BALL. THE BALL IS CLITIN, WHICH MAKES AN IRREGULAR SHAPE AND VILNIAN GAPS IN WHICH GAS CIRCULATES. MESOPHYL ON THE BOTTOM SURFACE OF THE LEAVES – THERE ARE FRIENDLY GUYS OF GREEN CLOTHES, BETWEEN THEM – A GRIFF. STOMA – A PAIR OF CLOSING CLITINA AND A MIDDLE CLITINA. GAS EXCHANGE AND MOISTURE DISCOVER THROUGH THE STUDS.
PHOTOSYNTHESIS, GAS EXCHANGE AND LEAF FALL ARE IMPORTANT FUNCTIONS, WITH GREEN LEAF IN THE LIFE OF ROSLYN. BATHROOM WITH NEW FUNCTIONS, SHEET TO CHANGE. FUNCTION SHEET
CHLOROPLASTS TURN UP IN DEEP CELLS. THE OUTER MEMBRANE IS SMOOTH, AND THE INNER HAS NUMEROUS FOLDS. BETWEEN THEM ARE PICKLES ASSOCIATED WITH IT, CALLED GRANTS. THEY PLACE THE GRAINS WITH CHLOROPHYL, A GREEN PIGMENT THAT PLAYS THE MAIN ROLE IN THE PROCESS OF PHOTOSYNTHESIS. IN CHLOROPLASTS, ATP is created, AND PROTEIN SYNTHESIS ALSO OCCURS. 2 1 - Thylakoid STROM; 2 – EXTERNAL MEMBRANE; 3 - Thylakoid facets; 4 – INNER MEMBRANE. BUDOV CHLOROPLAST CHLOROPLAST – GREEN COLOR. CHROMO PLASTICS – RED AND ZHOVTIY. LYCOPLASTS - UNPAINTED PARTS OF ROSLINI.
SIMPLE AND FOLDING LEAVES: 1 - BUSINESS; 2 – APPLE TREE; 3 – MAPLE; 4 - CLOVER; 5 - Kulbaba; 6 – ROSE HIP; 7 – RASPBERRY; 8 – Sunitsya; 9 - LUPINE. There are essentially no shapes and sizes of leaves, but there are only two different types. Simple leaves are folded into one leaf blade. THE FOLDING LEAVES ARE FURNISHED BY CLAMPS OF SMALLER LEAF PLATES, CALLED TELEPHATES, GROWING FROM ONE LEAF PETOIL.

Roslini leaf
- The main part of the leaf is flat and widened. They are called sheet scarves.
- Most leaves have a petiole coming out of the leaf blade. It is richly narrower than a leafy plant and similar to a stem. The petiole can change its position in the space by rotating the leaf blade. It is especially good when the leaves flutter in the light breeze. Once the petiole of the leaf itself is turned, you can turn your leaf blade until it becomes light so that it absorbs as much of the dormouse as possible.
- The place where the petiole is attached to the stem is now slightly wider. This is the base of the sheet.
Leaflets
Marvel at the stable leaf. What is it? At the base of the leaf, tightly pressed from both sides to the petiole, there are two small leaves. This is also part of the leaf. Such growths around the base of the leaf are called leaflets. The stench can be as strong as the mold and the spoilage. Not all leaflets are serrated.

Head to the lesson.
Organizational moment
Verification and appearance of knowledge
1. (Slide 1) Give meaning to the concepts: node, internode, leaf axil and label them on the diagram.
2. (slide 2) Like leaves, the leaves are growing at the pagons. Point the butt of Roslyn.
3. (slide 3) How do they separate nirks for flow?
How do the nirks separate behind the interior?
What kind of vegetative nirka is there?
Development of new material
Guess what is called the flow?
(slide 4) Lesson topic. Arkush – part of the time. outer and inner sheets of wood.
(slide 5) The leaf is one of the main organs of the plant, which occupies its most important position.
1. Functions of the arch: (Recorded by Zoshit)
Gas exchange
Water vaporization
Vegetatively not propagated
Creation of organic substances (photosynthesis)
At the end of the lesson, you are obliged to report on your questions(slide 6) What devices does the leaf have for promoting the process of photosynthesis?
2. The arkush can be folded(Slide 7) from sheet scarf(!), petiole (!) , leaves and supports, which are attached to the stem, as well as on the leaf there are good veins.
3. U Bagatioh Roslin(slide 8) the leaves are simple, there is only one leaf blade (butt - maple, kulbaba, apple tree, buzok)
Є roslini, (slide 9) Some leaves have a bunch of leaf blades. The leaves are also called folding (butts - stable, raspberry, sunitsa, shipshina, lupine)(slide 10)
4. When looking at the outside of the leaf, it is clearly visible that there are clearly visible veins on the leaf blade of the many shoots. They have bundles of wire and mechanical fabric. In different trees, the veins vary in different ways(slide 11) The pinnae and finger veins are divided into veins, which are typical for dicotyledonous plants, while the parallel and arcuate veins are characteristic of monocotyledonous plants.

6. The bud leaf can be examined under a microscope(slide 12)
Call sheet covered with sandpaper(!). On the lower surface of the leaf there are dead fruits (budova). Gas exchange occurs through them(!) And the vologa is vaporized. The middle of the leaf contains a lot of chlorophyll-bearing tissue - pulp (photosynthesis). Behind the external appearance, the tissues and their growth in the pulp of the leaf are often separated(!) and spongy fabric (specific features of its function). Wiring tissues are represented by bundles (veins). The stench comes from the trees (xylemi) and lubu (phloemi). The bundles that are made are lined with mechanical fabric, which protects the sheet from tearing and gives it elasticity and softness.

Guys, what are we talking to you about today? (Types of students).
Right. Known from a leaf
(Slide 3) Lesson topic. The surface of the bud leaf.
While we're on the topic of the lesson, let's figure out what you're going to learn in class today.
Vivchenya new ones
(Slide 4)
The leaves are in disarray.
Yellows, greens, reds,
Cirrus, round, oval.
With teeth and whole edges.
And maybe forgive and fold,
Sessile and petiolate.
Otherwise, it’s not important how...
Aje Roslini grubs on them.
The leaf is undergoing photosynthesis,
And organic speech gives life!
For sure, my friend, don’t tear the leaf!
And the beauty of the world is budova yogo vchi!
The largest leaf of the Amazonian Victoria is up to 1 m. The Victoria's arcus is so large that a territorial child can sit on it, like on a raft.
The smallest leaf of duckweed has a leaf diameter of up to 3 mm.
(Slide 5) The leaves have a different shape, and all of them have three main functions.
(slide 6) (click 1,2,3) leafing out vivaporate water, (Klatsannya 4,5,6,7,8) remove carbon dioxide and see sourness in the process of photosynthesis, (Klatsannya 9,10,11,12,13) Gas exchange occurs, during which sourness fades and sourness appears.
(Slide 7)Exterior of budova sheet
Although the leaves of different trees look very disturbed in appearance, there are hidden signs between them:
Most leaves are green in color,
add up to: (Klatsannya 1,2)- leaf blade - expanded part of the leaf, (Klatsannya 3.4) petiole - a narrow stem-like part of a leaf, (Klatsannya 5.6) the base of the leaf is the part by which the petiole is attached to the stem, (Klatsannya 7,8,9) the veins of the leaf sway.
(Slide 8) At the base of the petiole, long shoots may have leaflets.
(Klatsannya 1) with leaflets (Klatsannya 2) without sheets
(Klatsannya 3.4) apply it
(slide 9) Attachment of leaf to stem
(Klatsannya 1) Chereshkovi (Klatsannya 2) Sedentary(Klatsannya 3,4,5,6) apply it
Paint the outside of the sheet. Sign the head parts.
(Slide 10) What's good about a simple leaf? Give me the name, which sheet is called forgive? Simple leaves are folded into one leaf blade
(slide 11) What's good about a folding leaf? Tell me, what kind of sheet is called folding? The folding leaf consists of several leaf blades and one petiole
Fizkulkhvilinka.From behind our desks, let’s see each other together
There is no need to make any noise at all,
Stand up straight, legs together,
Turn right to the place.
We get moldy a couple of times near the valley.
I drown the little ones.
And now it’s clear, children,
Otherwise our hands are like forks.
Kidnapped by them together,
Otherwise the wind is fresh
The wind died down. They died together
We need to live this lesson.
We caught up and sat down quietly
And they marveled at the little girl.
(slide 12) The simple and folding leaves have a distinct shape to the edge of the leaf blade.
(slide 13) (click 1,2,3) The leaf blades are pierced in different directions by bundles that are called veins.
The veins are constantly drained of water and given to the leaf.
(Klatsannya 4.5) parallel - veins are arranged in parallel one to one (Klatsannya 6.7) often - the veins become silky, creating a strong boundary (Klatsannya 8.9) arc - the veins are distended at the appearance of the arc(slide 14) the middle of the leaf with various veins can be seen (Klatsannya 1,2) peristeta
finger (Klatsannya 3.4) apply it
