Answer 1

Ответ:

Восходящий ток

1. Вода, минеральные соли.

2. Движется по ксилеме ( проводящая ткань растений).

3. Вещества движутся к листьям для поддержания фотосинтеза.

Нисходящий ток

1. Растворенные органические вещества.

2.Движется по флоэме ( проводящая ткань растений).

3. Вещества движутся ко всем остальным органам растения.

Answer 2

Movement of Water and Nutrients in Plants

In plants, the movement of water and nutrients occurs through two main processes: ascending (upward) and descending (downward) transport systems.

I. Ascending Transport (Xylem)

1. Substances Transported: Water and minerals are transported through the xylem vessels. - The xylem vessels are responsible for transporting water and minerals from the roots to the rest of the plant.

2. Vessel Type: These substances are moved through specialized tubes called xylem vessels. - Xylem vessels are the main transport system for water and minerals in plants, providing a pathway for the upward movement of these substances.

3. Direction: The substances are directed upwards from the roots to the stems and leaves. - Water and minerals are transported upwards from the roots to the stems and leaves, where they are utilized for various physiological processes.

II. Descending Transport (Phloem)

1. Substances Transported: The phloem transports organic compounds, such as sugars, from the leaves to other parts of the plant. - Phloem is responsible for transporting organic compounds, including sugars, from the leaves to other parts of the plant.

2. Vessel Type: These substances are transported through specialized tubes called phloem vessels. - Phloem vessels form the main transport system for organic compounds, facilitating their movement throughout the plant.

3. Direction: The substances are directed downwards from the leaves to other parts of the plant, such as the roots and developing fruits. - Organic compounds, particularly sugars produced during photosynthesis, are transported from the leaves to other parts of the plant, including the roots and developing fruits.

These processes are essential for the distribution of water, minerals, and organic compounds throughout the plant, supporting its growth, development, and metabolic functions.
