Study Notes
Plant Tissues
- Parenchyma is the most common simple permanent tissue, consisting of relatively unspecialized cells with thin cell walls that are living cells.
- Collenchyma allows bending of various parts of the plant, such as tendrils and stems of climbers, without breaking.
- Sclerenchyma tissue makes the plant hard and stiff, and is found in stems, around vascular bundles, in the veins of leaves, and in the hard covering of seeds and nuts.
- Sclerenchyma cells are long and narrow, with thickened walls due to lignin.
Irrigation
- Irrigation is the process of supplying water to crop plants through human efforts using canals, wells, reservoirs, and tube wells.
- The most common source of irrigation is tube wells.
Mixtures and Solutions
- Mixtures are constituted by more than one kind of pure form of matter.
- Sodium chloride is a pure substance, not a mixture.
Tyndall Effect
- The Tyndall effect is the scattering of light by colloidal particles, making the path of a beam of light visible.
- Examples of the Tyndall effect include the visibility of sunlight passing through the canopy of a dense forest and the scattering of light by particles of dust or smoke in a dark room.
Other
- Apical and intercalary meristems are not permanent tissues.
- Aerenchyma helps aquatic plants to float, but does not provide mechanical support.
- Lignin is the chemical deposited on the walls of sclerenchyma cells, making them impervious to water and air.
