Transport in Plants Class 11 Notes Biology Chapter 11 → Plants obtain a variety of inorganic elements (ions) and salts from their surroundings especially from the air, water, and soil. The movement of these nutrients from the environment into the plant as well as from one plant cell to another plant cell essentially involves movement…

Cell Cycle and Cell Division Class 11 Notes Biology Chapter 10 → According to the cell theory, cells arise from pre-existing cells. The process by which this occurs is called cell division. → Any sexually reproducing organism starts its life cycle from a single-celled zygote. → Cell division does not stop with the formation of…

Anatomy of Flowering Plants Class 11 Notes Biology Chapter 6 → Anatomically, a plant is made up of different kinds of tissues. Tissue is broadly classified into meristematic (apical, lateral, and intercalary) and permanent (simple and complex) tissues. → Tissues perform various functions such as assimilation, mechanical support, storage, and transportation of materials such as…

Plant Kingdom Class 11 Notes Biology Chapter 3 → Plant kingdom includes algae, bryophytes, pteridophytes gymnosperms, and angiosperms. → Algae are chlorophyll-bearing simple, thalloid, autotrophic, and largely aquatic organisms. Depending on the type of pigment possessed and the type of stored food, algae are classified into three classes, namely Chlorophyceae, Phaeophyceae, and Rhodophyceae. → Bryophytes…
