“Class Dicotyledonous” - Seed embryo with two cotyledons. The fruit is a pod and pod. Rose hip. The calyx is represented by a tuft. Signs of Dicotyledons. The leaves usually have pinnate veins. The flower consists of five fused sepals. Lupine. Family Cruciferous (Cabbage). The flower has a double perianth. Levka. Family Solanaceae.

The seed is the embryonic plant. It develops from the ovule and it arose as a result of a long process of evolution as the organ that most reliably ensures their reproduction and distribution. According to the structural features of their seeds, all flowering plants are divided into 2 classes: n Monocots and dicotyledons.
Dicotyledons n n The bean seed develops inside a fruit called a pod. On the concave side of the seed there is a hilum - the place where the seed is attached to the valve of the fruit. The outside of the seed is covered with a thick skin. The seed embryo is located under the skin. It consists of two cotyledons, a root, a stalk, and a bud. The cotyledons develop symmetrically opposite each other. Sometimes the embryo has one cotyledon (chistyak, corydalis species, some umbelliferae). For 1 slide
n The cotyledons contain a supply of nutrients. But in some (wild radish, shepherd's purse), the supply of nutrients is located not only in the cotyledons, but also in other parts of the embryo - the root, the stem. The growth cone of the embryonic stem is located between the cotyledons and already in the embryo forms rudimentary leaves. All together forms a bud, which is the rudiment of the main shoot of the plant. Cotyledons usually have 3 main vascular bundles and are brought to the surface during seed germination. Bean seed: peel, seed embryo, 2 cotyledons, root, stalk, bud. Conclusion: Flowering plants whose embryos have 2 cotyledons are called dicotyledons. For 1 slide
Legume Plants Beans come in a variety of shapes and sizes. The largest bean is entada climbing – one and a half meters. And the largest seeds in the world are from the South American mimosa oilifera. They are 17 - 20 cm long. Beans, peas, vetch, white acacia, soybeans, lupine, peanuts, mimosa - all these plants hide their seeds in beans. For 1 slide
Monocots Let's look at the structure of a wheat seed. The grain of wheat is not a seed, but a fruit. The fruit tissue in the grain is represented only by a filmy outer layer, called the fruit membrane. The rest of the grain is the seed. Along the seed there is a groove on which there is a scar. The wheat grain consists of the germ, nutritional tissue called endosperm and the seed coat. The embryo in the grain occupies a very small place; the main part of it is the endosperm. The grain of wheat is essentially both a seed and a fruit called the caryopsis. The grain embryo consists of a germinal root, a stalk, a bud and a scutellum. For 1 slide
What's inside a seed? Nutrient reserves are deposited inside the seed, in the cotyledons. Cereals, particularly wheat, contain the most starch. It is necessary for feeding the germinating embryo. For 1 slide.
It is believed that the scutellum is the only modified cotyledon of the embryo, which does not contain a supply of nutrients, fits tightly to the endosperm and looks like a thin plate. The scutellum is positioned as if it forms a partition between the embryo and the endosperm, and during seed germination it 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 growth cone) is located to the side of it. Cotyledons usually have two main vascular bundles; When the seed germinates, it is not brought to the surface. For 1 slide
Wheat grain: 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 adhere to it on one side, as in wheat and other cereals. Conclusion: Flowering plants whose embryos have 1 cotyledon are called monocots. For 1 slide
