We pose a problem

Pupil:

I saw how the swollen bean seed split into two equal halves? Why?

Biologist :

Yes, there are seeds that fall into two halves, but there are also those that do not separate. This is one of the signs of plants. But which ones,

today we have to find out.

A seed is a rudimentary plant. It develops from the ovule and it arose as a result of a long evolutionary process as an organ that most reliably ensures their reproduction and distribution. According to the peculiarities of the structure of seeds, all flowering plants are divided into 2 classes: n Monocotyledonous and dicotyledonous.

Dicotyledonous n n Bean seed develops inside a fruit called a bean. On the concave side of the seed there is a scar - the place of attachment of the seed to the valve of the fruit. The outside of the seed is covered with a dense skin. A seed embryo is placed under the skin. It consists of two cotyledons, a root, a stem, and a bud. The cotyledons develop symmetrically against each other. Sometimes the embryo has one cotyledon (cleaver, crested species, some umbellates). 1 slide

n The cotyledons contain a supply of nutrients. But in some (wild radish, shepherd's purse), the supply of nutrients is not only in the cotyledons, but also in other parts of the embryo - the root, the stalk. The growing cone of the embryonic stem is located between the cotyledons and forms embryonic leaves already in the embryo. All together forms a bud, which is the rudiment of the main shoot of the plant. Cotyledons usually have 3 main vascular bundles; during seed germination, they are brought to the surface. Bean seed: skin, seed embryo, 2 cotyledons, root, stalk, bud. Conclusion: Flowering plants, the embryos of which have 2 cotyledons, are called dicotyledons. 1 slide

Legumes Beans come in a wide variety of shapes and sizes. The largest bob - climbing entads - one and a half meters. And the largest seeds in the world are in the South American oil-bearing mimosa. They are 17 - 20 cm long. Beans, peas, vetch, acacia, soybeans, lupine, peanuts, mimosa - all these plants hide their seeds in beans. 1 slide

Monocots Consider the structure of the wheat seed. A grain of wheat is not a seed, but a fruit. Fruit tissues in the caryopsis are represented only by the membranous outer layer, called the fruit shell. The rest of the caryopsis is the seed. A groove runs along the seed, on which the scar is located. A wheat grain is made up of an embryo, a nutrient tissue called the endosperm, and a seed rind. The embryo in the weevil occupies a very small place, the main part of it is the endosperm. A grain of wheat is essentially both a seed and a fruit called a caryopsis. The embryo of a weevil consists of an embryonic root, a stalk, a bud, and a shield. 1 slide

What's inside the seed? Inside the seed, in the cotyledons, reserves of nutrients are deposited. Cereals, in particular wheat, contain the most starch. It is necessary to feed the germinating embryo. 1 slide

It is believed that the scutellum is the only modified cotyledon of the embryo that does not contain a supply of nutrients, is tightly attached to the endosperm and looks like a thin plate. The scutellum is located as if it forms a septum between the embryo and the endosperm and the germination of the seed takes nutrients from the endosperm. In monocots, the cotyledon is located at the top of the longitudinal axis of the embryo, and the bud (with a cone of growth) is located aside from it. The cotyledon usually has two main vascular bundles; when germinating, the seed is not brought to the surface. 1 slide

Wheat caryopsis: pericarp fused with the seed coat, endosperm, seed embryo, scutellum, root, stalk, bud. In other monocotyledonous plants (onion, lily of the valley), the seeds also have an endosperm, but it surrounds the embryo, and does not adjoin it on one side, as is the case with wheat and other cereals. Conclusion: Flowering plants, the embryos of which have 1 cotyledon, are called monocotyledonous. 1 slide
