Plant Structure and Growth
Roots anchor, the plant, ingest minerals and water, direct water and supplements, and store food. These are two kinds of root frameworks.
Plant Life Cycle
Plants are part of the PLANT KINGDOM, which is one of the five kingdoms of life. Plants are divided into smaller classes based on common characteristics. Certain characteristics are shared by all plants. They are made up of a large number of cells. They …
Life Cycle of Plants
All the organisms that belong to the Kingdom Plantae are known as plants. They are multicellular and eukaryotic and can synthesize their food by photosynthesis, known as autotrophic organisms. They are classified based on certain characteristics, such as…
Plant Morphology and Anatomy
The study of life and organisms is biology. The cell is recognized as the basic unit of life by biology. From ancient Greek, biology is recognized. Modern biology deals with the recent developments in Science.
