The structural organization of plants and animals is an important topic in NEET-BIOLOGY. It refers to the different levels of organization within living organisms, including their cells, tissues, organs, and organ systems.
In plants, the structural organization includes the following levels:
- Cells: The basic unit of plant structure and function is the cell, which is responsible for performing all the necessary functions of life. Plant cells are surrounded by a cell wall, which provides structure and support.
- Tissues: A tissue is a group of similar cells that work together to perform a specific function. In plants, there are three main types of tissue: dermal tissue, ground tissue, and vascular tissue.
- Organs: An organ is a group of tissues that work together to perform a specific function. In plants, examples of organs include leaves, stems, and roots.
- Organ systems: An organ system is a group of organs that work together to perform a specific function. In plants, there are two main organ systems: the shoot system and the root system.
In animals, the structural organization includes the following levels:
- Cells: Like plants, the basic unit of animal structure and function is the cell. However, animal cells do not have a cell wall and are typically more specialized than plant cells.
- Tissues: In animals, there are four main types of tissue: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
- Organs: An organ is a group of tissues that work together to perform a specific function. In animals, examples of organs include the heart, liver, and lungs.
- Organ systems: An organ system is a group of organs that work together to perform a specific function. In animals, there are several organ systems, including the digestive system, respiratory system, and nervous system.
Understanding the structural organization of plants and animals is important for understanding how these organisms function and interact with their environment. It is also important for understanding the mechanisms underlying diseases and developing effective treatments for those diseases.
What is NEET-BIOLOGY Structural organization-Plants and animals
In NEET-BIOLOGY, the term “Structural organization-Plants and animals” refers to the study of the hierarchical levels of organization that make up the bodies of plants and animals. These levels range from the smallest functional units, such as cells, to tissues, organs, and organ systems.
The structural organization of plants and animals is characterized by their complexity, with each hierarchical level performing specialized functions that contribute to the overall functioning of the organism. For example, cells are the basic building blocks of living organisms and perform specific functions, such as carrying out metabolic processes or providing structural support. Tissues are formed when cells of a similar type come together to perform a common function, such as muscle tissue, which is made up of muscle cells and responsible for movement. Organs are formed when tissues come together to perform more complex functions, such as the heart, which is an organ composed of muscle tissue and responsible for pumping blood. Organ systems are groups of organs that work together to perform a specific function, such as the digestive system, which is composed of organs such as the stomach and small intestine that work together to break down food.
The study of the structural organization of plants and animals is important for understanding how they function and how they interact with their environment. It is also important for diagnosing and treating diseases, developing new medical treatments, improving agricultural practices, and promoting environmental conservation.

During the Renaissance period in the 15th and 16th centuries, scientists such as Leonardo da Vinci and Andreas Vesalius made significant contributions to the study of the structural organization of living organisms. Da Vinci was one of the first to use detailed anatomical drawings to study the human body, while Vesalius conducted dissections and used illustrations to study human anatomy in greater detail.
In the 17th and 18th centuries, the study of the structural organization of living organisms became more scientific and systematic, with the development of the microscope and the use of scientific methods for observation and experimentation. Scientists such as Robert Hooke and Antonie van Leeuwenhoek made significant contributions to the study of cells and microorganisms, while Carl Linnaeus developed a system of classification for living organisms based on their structural organization.
In the 19th and 20th centuries, advances in technology and the growth of the field of genetics led to significant advances in the study of the structural organization of living organisms. Scientists such as Charles Darwin and Gregor Mendel made groundbreaking discoveries in the fields of evolution and genetics, while others such as Louis Pasteur and Robert Koch made significant contributions to the study of microbiology and disease.
Today, the study of the structural organization of plants and animals is an important area of research in modern biology, with applications in fields such as medicine, agriculture, and environmental science.
