In potato osmometer, which of the following process is involved?

In potato osmometer, the potato scoop is filled with sugar solution and is kept in a beaker containing water. Now, due to osmosis which is the net movement of water molecules from a region of their higher concentration to a region where their concentration is low through a differentially permeable membrane, water comes inside the potato. Since a chemical gradient is developed along which there is physical movement of water, it is a physico- chemical process.

Notes on Transport in Plants

Concepts Used:

Transport in Plants

The two types of conducting tissues that are used to transport the water and minerals in plants such as:

Xylem:

Xylem is a long, non-living tube running from the roots to the leaves via the stem. The water is absorbed by the root hair and goes through cell-to-cell movement by osmosis until it reaches the xylem. This water is then transported throughout the xylem vessels to the leaves and is evaporated by the process of transpiration.

The xylem is also composed of lengthened cells like the phloem. However, the xylem is mainly accountable for transporting water to all plant parts from the roots. Since they serve such a vital function, a single tree would have a lot of xylem tissues.

Phloem:

The phloem is accountable for the translocation of nutrients and sugar like carbohydrates, produced by the leaves to areas of the plant that are metabolically in force. It is powered by living cells. The cell walls of these cells structurize small holes at the ends of the cells known as sieve plates.

Means of Transportation in Plants:

Transportation in plants is by 3 means, they are as follows:

Diffusion
Facilitated diffusion
Active Transport
