Question

Интересные факты о корнях

Answer 1

Корень-один из вегетативных органов растения. Имеет неограниченный рост и положительный геотропизм. 
Функции корня:
-закрепляет растения в почве;
-поглощает и проводит в наземные органы воду и растворы минеральных солей;
-синтезирует биологически активных веществ(гормоны,алканоиды);
-выделяет в почву различные кислоты(яблочную,угольную);
-участвует в дыхании растения;
-орган вегетативного размножения;
-вступает в симбиоз с клубеньковыми бактериями и грабами(микориза)
Виды корней:
а) Главный корень - образуется при прорастании семени из корешка зародыша;
б) Придаточные корни - образуются на стеблях и листьях;
в) Боковые корни - ветвления главного и придаточного корней.
Совокупность всех корней одного растения составляет его корневую систему.
Корни могут иметь форму цилиндрическую(хрен), коническую (одуванчик), нитевидную(злаковые).  

Answer 2

Корни помогают дереву крепко стоять , питательные вещества тоже проникают через корень

Interesting Facts about Roots

Roots are fascinating structures that play a crucial role in the growth and development of plants. Here are some interesting facts about roots:

1. Types of Roots: There are different types of roots found in plants. The two main types are taproots and fibrous roots. Taproots have a main root that grows vertically into the ground, while fibrous roots are a dense network of thin roots that spread horizontally.

2. Functions of Roots: Roots serve several important functions for plants. They anchor the plant in the soil, absorb water and nutrients, store food reserves, and provide support for the above-ground parts of the plant.

3. Root Growth: Roots grow in response to various environmental factors. They can grow towards sources of water and nutrients, a process known as positive geotropism. Additionally, roots can also exhibit negative geotropism, growing away from certain stimuli such as light.

4. Root Hairs: The surface of roots is covered with tiny hair-like structures called root hairs. These root hairs greatly increase the surface area of the root, allowing for more efficient absorption of water and nutrients from the soil.

5. Root Systems: Different plants have different root systems. Some plants, like grasses, have shallow root systems that spread out near the surface of the soil. Others, like trees, have deep taproots that penetrate deep into the ground.

6. Root Grafting: Root grafting is a process where the roots of two different plants are joined together. This technique is often used in horticulture to propagate plants and create stronger root systems.

7. Medicinal Roots: Many plants have roots that are used for medicinal purposes. For example, ginseng root is highly valued in traditional medicine for its potential health benefits.

8. Root Vegetables: Some edible plants store their nutrients in their roots, making them popular as root vegetables. Examples include carrots, radishes, and sweet potatoes.

9. Root Systems and Soil Erosion: The presence of a dense network of roots can help prevent soil erosion by stabilizing the soil and reducing the impact of water and wind.

10. Roots and Carbon Sequestration: Roots play a crucial role in carbon sequestration, the process by which carbon dioxide is removed from the atmosphere and stored in the soil. The roots of plants help to stabilize organic matter in the soil, which can store significant amounts of carbon.

These are just a few interesting facts about roots. Roots are an essential part of the plant's structure and function, and they contribute to the overall health and growth of plants.
