Yes, turgor pressure is important for mineral uptake in plants. It helps in the movement of water and minerals from the soil into the plant roots through osmosis. Turgor pressure also maintains cell rigidity and structure, which is essential for the proper functioning of the root system in absorbing minerals.

What tonic maintains turgor pressure?
Plant cells maintain turgor pressure through the uptake of water into their central vacuole, which is filled with a solution of ions and molecules called the cell sap. The main ion responsible for maintaining turgor pressure in plant cells is potassium, which actively moves into the vacuole to drive water uptake and support cell rigidity.
What is the cause of tugor pressure and its effect on plant tissue?
Turgor pressure is caused by the osmotic uptake of water into plant cells, creating internal pressure against the cell wall. This pressure helps maintain cell shape and rigidity, supporting the plant structure. Loss of turgor pressure can lead to wilting and decreased growth in plants.
Why are stomata and guard cells called turgor operated valves?
Stomata and guard cells are called turgor-operated valves because their opening and closing are regulated by changes in turgor pressure within the guard cells. When the guard cells become turgid from water uptake, they bow outwards and cause the stomatal pore to open. Conversely, when the guard cells lose water and become flaccid, the pore closes.
Why is transpiration stream important?
The transpiration stream is important because it helps to transport water and nutrients from the roots to the leaves of a plant. This process is essential for maintaining turgor pressure in plant cells, which in turn supports plant structure and growth. Additionally, the movement of water through the plant helps to cool the leaves and assists in the uptake of minerals and other essential nutrients from the soil.
Why does the root need root hairs for the uptake of water and mineral?
because absorption of water takes place by root hairs in the root
