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