How Much Do You Know About Water Absorption and Circulation in Plants?

• Water in higher plants exists in liquid, gaseous, and solid forms.
• Free water and bound water are found in the cytoplasm of plants.
• The root is the specialized organ for absorbing water and mineral substances.
• The amount of water absorbed by plants depends on the volume and spread of the root system, as well as the amount and force of water retention in the soil.
• Plants absorb accessible forms of water, including gravity water, capillary water, and peripheral layers of film water.
• Inaccessible forms of water in the soil include hygroscopic water, constitutional water, and internal layers of film water.
• The ratio of free water to bound water varies depending on the species and environmental conditions.
• Plants with a high content of free water are not resistant to freezing.
• The mycorrhiza is a type of symbiotic fungi that can help plants absorb water and mineral substances.
• Agricultural works can optimize the growth of the root system.

1. Water is absorbed by the roots through absorbent perispore and root epidermis cells.
2. Water absorption is achieved through passive and active mechanisms.
3. Internal factors such as respiratory activity and sanitary condition of the plant influence water absorption.
4. External factors such as soil temperature, light, soil aeration, concentration and pH of soil solution, and toxins from the soil also affect water absorption.
5. Water can be absorbed through aerial organs such as leaves, stem, and buds.
6. Young leaves can absorb up to 50% of the required amount of water.
7. Water is transported throughout the plant's body through osmotic and specialized vessels.
8. Osmotic circulation of water takes place passively and actively.
9. Water circulates radially towards the inside of the root in the area of the absorbent bristles.
10. Active circulation of water through the root of grass plants is achieved with the part.

• Water circulates osmotically from roots to leaves
• Endoderm is the last layer of bark that resists water circulation
• Root pressure arises at the perisori-endoderm distance
• Water is pushed into wooden vessels by root pressure
• Integral permeability of cellular plasma membranes facilitates connection between roots and leaves
• Conducting system of woody vessels connects roots and leaves
• Tracheids are specific to vascular cryptogams and gymnosperms
• Tracheas are found in angiosperms
• Tracheids have sharp ends and perforations, with thickened membranes
• Tracheas are formed by parenchymal cells with thickened side walls in the form of rings, spirals, or reticulations.
