Question

Чем отличаются друг от друга боковые корни и придаточные корни. СРОЧНО *)

Answer 1

Ответ:Придаточные корни в отличие от боковых корней образуются не на корне, а на других органах растения. Они могут образовываться на стеблях, листьях, корневищах, но никогда придаточные корни не развиваются из главного и боковых корней. Внешне придаточные корни не отличаются от обычных корней и выполняют те же функции (закрепление растения в почве, поглощение воды и минеральных солей и др.) . У многих растений, как например, у однодольных (злаки, лилейные, осоковые и др.) , корневая система состоит преимущественно из придаточных корней. Такие же корни образуются и у папоротникообразных (папоротники, хвощи) . Придаточные корни иногда составляют основную массу корней и у двудольных растений. Так, например, у картофеля, когда он размножается клубнями, образуются только придаточные корни. При вегетативном размножении растений, т. е. при размножении черенками, усами, отводками, корневищами, развиваются только придаточные корни.

Difference between Lateral Roots and Adventitious Roots

Lateral roots and adventitious roots are two types of roots found in plants. While they both serve the purpose of anchoring the plant and absorbing water and nutrients, there are some key differences between them.

Lateral Roots: Lateral roots are roots that originate from the primary root, also known as the taproot. They emerge from the sides of the primary root and grow horizontally. Lateral roots are typically found in dicotyledonous plants, which have a taproot system. These roots play a crucial role in providing stability to the plant and absorbing water and nutrients from the soil.

Adventitious Roots: Adventitious roots, on the other hand, are roots that develop from non-root tissues, such as stems, leaves, or even other roots. Unlike lateral roots, adventitious roots do not arise from the primary root. They can emerge from various parts of the plant, depending on the species and environmental conditions. Adventitious roots are commonly found in monocotyledonous plants, which have a fibrous root system.

Key Differences: 1. Origin: Lateral roots originate from the primary root, while adventitious roots develop from non-root tissues. 2. Growth Pattern: Lateral roots grow horizontally from the primary root, while adventitious roots can grow in any direction, depending on their point of origin. 3. Location: Lateral roots are typically found on the sides of the primary root, while adventitious roots can emerge from various parts of the plant, such as stems, leaves, or other roots. 4. Function: Lateral roots primarily serve the purpose of anchoring the plant and absorbing water and nutrients from the soil. Adventitious roots can have various functions, such as providing additional support, absorbing water and nutrients, or aiding in vegetative propagation.

It's important to note that the specific characteristics of lateral roots and adventitious roots can vary among different plant species and environmental conditions. The information provided here is a general overview of the differences between these two types of roots.
