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 also make their own food through a chemical process called photosynthesis, which involves the use of water, carbon dioxide, and solar energy. They pump life-giving oxygen into the air as a by-product.
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 the plants bear flowers; some have only naked seeds and do not contain flowers. Some plants neither have seeds nor flowers, such as ferns and mosses.
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.
Meristem – Meristem is a type of tissue present in plants. This tissue contains meristematic cells which are capable of cell division. Cells which are present in meristematic tissue are capable to develop into any tissue or organ which is present in plants.
Its Location – Meristematic tissue is located at different places like:
- Tips of roots and stem
- Buds and nodes of stems, etc.
Meristem is divided into three different types depending on the occurrence of the meristematic tissue:
- Apical meristem - The apical meristems is located on the tip of the root, stem etc. It helps in the growth of root system and shoot system. The growth of stem above the ground and growth of roots below the ground, both of these growths are achieved by different types of cell divisions and cellular enlargement.
- Intercalary meristem – The intercalary meristems are located at the internodes or at the base of leaves. It helps in increasing the length of the internodes. This can be present in monocotyledonous plants.
- Lateral meristem – The lateral meristem is present at the lateral side of root and stems. It helps in increasing the thickness of plants.
Cambium: Cambium is a layer of tissues. It helps in the growth of the plants. It is found in the area between xylem and phloem. It is responsible for secondary growth of stem and roots.
