Investigating the Effect of Different Solutions on Plant Cells

The aim of my experiment is to find the effects of different solutions on plant cells. Osmosis is a form of diffusion, the movement of molecules to allow them to mix, which occurs in plants. When a cell containing a weak solution is next to a cell containing a stronger solution the water in the weaker solution moves towards the stronger solution.

The influence of ammonia in nutrient solution on growth ...

Shoot yield of cucumber plants grown 18 days in nutrient solution with 0.06 mM NH3 was decreased. Root yield was diminished at 0.09 mM NH3 The ammonia treatment caused heavy chlorosis increasing with age of leaves. This chlorosis was not due to any nutrient deficiency. Ammonia also influenced the morphology of roots. They were clearly shorter caused by a much smaller size of root cells.

Osmosis: Definition, Effect on cell and Example Micro B Life

Osmosis is how plants are able to absorb water from soil. The roots of the plant have a higher solute concentration than the surrounding soil, so water flows into the roots. In plants, guard cells are also affected by osmosis. These are cells on the underside of leaves that open and close to allow gas exchange. When the plant’s cells are full ...
