Summer nature

Bring a few such plants in the jar with water and you can watch from the green plates of the oxygen bubbles appear, if duckweed immersed in water. For this beam ryasok try to sink your fingers and cover up his escape Urut or Elodie. The very next day you will notice that each Lemna separated gas bubble. Shake the jar, and you will see how quickly vacated sunk duckweed'll come out top. Duckweed interested in its asexual reproduction. Each plate is separated from the duckweed itself two or three are the same plate. A few days later the new plates come off the old and become independent plantlets. And here is another floating plant is much larger than duckweed. It blooms in July and August. Its rounded leaves have a reniform shape. From each plant depart downward long white roots, lined with thin hairs. This vodokras or frogbit. It gives thin shoots, which are formed at the ends of the kidney - the beginning of new bushes. Each new bush for some time associated with the parent plant green shoots. Bottom of the leaves vodokrasa can often see the snails, as well as adhering gelatinous sausage eggs pond. Among the aquatic plants is also such that for their nutrition like animals - is pemphigus. She does not have roots and leaves under the water surface. They dissected into trichoid cloves, and some of them have bubbles, similar to the bags. Each vial has an opening and serves as a plant for catching prey. Peer more closely into these bags. Through the thin walls in many of them shine tiny crustaceans (Cyclops, Daphnia) or other small aquatic animals, trapped there as a trap. Some of the prisoners still stir, the rattle of its western wall, while others lie motionless - no signs of life, others have almost disintegrated, and the soft parts of their bodies went into the food plant. In the Moscow region are known three types of bladderwort (Utricularia minor L., U. intermedia Hayne, U. vulgaris L.). In July and August they are blooming small yellow flowers, sitting on slender peduncles. In the second half of July, ripen fruits at a number of plants: a raspberry, bramble, wild honeysuckle, and red elderberry, ripen in the gardens of red berries and black currants. In August, the fruits ripen already cranberry, mountain ash and ordinary snowball. In late July, begin to crumble birch seeds. Each birch seed is equipped with two webbed wings. This device facilitates the dissemination of seeds by wind that blows them away from the parent tree. Everywhere there are fungi - edible and poisonous. Bright blush fly agaric caps, not even eaten snails. The second half of summer - the time of the greatest development of fungi. In some woodlands mushroom picking is of great economic importance. With an abundance of forest people have in many places so spoiled by fungi that do not eat any except white, occasionally deigning to the taking aspen and boletus. Almost all edible mushrooms, with the exception of spring morels and lines, you can find in July, August and September. Many fungi have a completely unfounded are neglected. These are: fungus, shaft, Belyankov, svinuhu, volnushku, kozlyaka, not to mention the morels and mushrooms, which in some places are valued as a delicacy, and we have many positive scorned. Even well-known to all white beads slicker edible when young, yet they fleshy and juicy and not turned into a thin-walled blisters filled with black as smoke, dust, microscopic spores.
