Question

в чём разница между плауна и хвоща? срочно надо

Answer 1

разница состоит во внешнем строении и их размножении

Answer 2

Отличие плаунов от хвощей: у хвощей сильно редуцированы листья; у хвощей имеется корневище, а не просто корни;стебли хвощей имеют членистое строение, эпидермис хвощей пропитан кремнеземом. Главное отличие папоротников от моховидных является то, что у мхов в жизненном цикле преобладает гаметофит, а у папоротников-спорофит. У мхов нет настоящих корней, у папоротник имеется корневище. У папоротников листья в виде вай, у мхов мелкие узкие листочки.

Difference between a fern and a horsetail

Ferns and horsetails are both types of plants that belong to the group of vascular plants known as pteridophytes. While they share some similarities, there are several key differences between the two.

Ferns: - Ferns are a diverse group of plants that have leaves, stems, and roots. - They reproduce through spores, which are produced in structures called sporangia located on the undersides of their leaves. - Ferns typically have large, compound leaves that are divided into smaller leaflets. - They are found in a wide range of habitats, including forests, wetlands, and even deserts. - Some common examples of ferns include the maidenhair fern, sword fern, and bracken fern.

Horsetails: - Horsetails, also known as equisetums, are a smaller group of plants that have a unique appearance. - They have hollow, jointed stems that are typically ribbed or ridged. - Horsetails reproduce through spores, which are produced in cone-like structures called strobili. - They have small, scale-like leaves that are arranged in whorls around the stem. - Horsetails are often found in wet habitats, such as marshes, swamps, and along riverbanks. - The giant horsetail (Equisetum giganteum) is one example of a horsetail species.

In summary, the main differences between ferns and horsetails lie in their overall appearance, leaf structure, and habitat preferences. Ferns have larger compound leaves and are found in a wider range of habitats, while horsetails have unique hollow stems with small scale-like leaves and are typically found in wet environments.
