Structural organization-Plants and animals
The structural organization of plants and animals refers to the hierarchical arrangement of cells, tissues, organs, and organ systems that make up these organisms. Let’s delve deeper into the structural organization of plants and animals:
Plants:
Cells: The basic unit of structure and function in plants is the cell. Plant cells have a cell wall, cell membrane, cytoplasm, and various organelles like chloroplasts, mitochondria, vacuoles, and nucleus.
Tissues: Plant tissues are groups of cells with similar structures and functions. There are three main types of plant tissues:
a. Meristematic Tissue: Responsible for growth and cell division.
b. Permanent Tissue: Comprises various cell types such as parenchyma, collenchyma, and sclerenchyma, which perform functions like storage, support, and photosynthesis.
c. Vascular Tissue: Consists of xylem and phloem, facilitating the transport of water, minerals, and nutrients throughout the plant.
Organs: Organs are structures composed of different tissues working together to perform specific functions.
a. Roots: Absorb water and nutrients from the soil, anchor the plant, and provide support.
b. Stems: Provide support, transport water and nutrients between the roots and leaves, and may store food.
c. Leaves: The primary site of photosynthesis, facilitating the absorption of sunlight and exchange of gases.
d. Flowers: Reproductive structures involved in pollination and fertilization.
e. Fruits: Develop from fertilized flowers and contain seeds.
Organ Systems: Plants have various organ systems that coordinate the functions of different organs.
a. Root System: Comprises the roots and associated structures.
b. Shoot System: Includes the stem, leaves, flowers, and fruits.
c. Reproductive System: Comprises the flowers and fruits involved in reproduction.
Animals:
Cells: Animal cells are similar to plant cells, consisting of a cell membrane, cytoplasm, organelles, and nucleus. However, animal cells lack a cell wall and possess specialized structures like centrioles.
Tissues: Animal tissues are categorized into four primary types:
a. Epithelial Tissue: Covers body surfaces, lines organs and cavities, and forms glands.
b. Connective Tissue: Provides support, connects and protects body parts, and stores fat.
c. Muscle Tissue: Responsible for movement and contraction.
d. Nervous Tissue: Facilitates the transmission of signals and coordinates body functions.
Organs: Organs in animals are composed of different tissues working together to carry out specific functions.
a. Digestive System: Comprised of organs like the stomach, intestines, and liver, involved in food digestion and absorption.
b. Respiratory System: Includes organs such as the lungs and trachea, facilitating the exchange of gases.
c. Circulatory System: Composed of the heart, blood vessels, and blood, responsible for transporting oxygen, nutrients, and waste products throughout the body.
d. Nervous System: Consists of the brain, spinal cord, and nerves, controlling and coordinating body activities.
e. Skeletal System: Comprised of bones, providing support, protection, and facilitating movement.
Organ Systems: Animals have several organ systems that work together to maintain overall body functions and homeostasis.

Case Study on NEET-BIOLOGY-SYLLABUS Structural organization-Plants and animals
Case Study: Structural Organization in Animals – The Human Respiratory System
Introduction: The respiratory system is responsible for the exchange of gases, specifically oxygen and carbon dioxide, between the body and the environment. In humans, this system consists of several organs and tissues that work together to facilitate respiration. Let’s examine the structural organization of the human respiratory system as a case study on structural organization in animals.
Case Study Overview: John is a 45-year-old male who has been experiencing shortness of breath and persistent coughing. He visits a pulmonologist to investigate his symptoms. The pulmonologist conducts a thorough examination, including a study of the structural organization of John’s respiratory system.
Structural Organization of the Human Respiratory System:
- Nose and Nasal Cavity: The respiratory system begins with the nose, the primary entrance for air. The external portion of the nose consists of cartilage and bone, while the internal nasal cavity is lined with ciliated epithelial cells and mucous membranes. The nasal cavity filters, warms, and humidifies incoming air.
- Pharynx: Located at the back of the throat, the pharynx serves as a common pathway for both air and food. It connects the nasal cavity and mouth to the larynx.
- Larynx: The larynx, commonly known as the voice box, is situated below the pharynx. It contains the vocal cords, which vibrate to produce sound during speech. The epiglottis, a flap of tissue, prevents food from entering the respiratory system during swallowing.
- Trachea: The trachea, or windpipe, is a tube composed of cartilage rings that provide structural support. It extends from the larynx and bifurcates into the right and left primary bronchi. The inner lining of the trachea is covered with cilia and mucous-secreting cells, which help in the removal of foreign particles.
- Bronchi and Bronchioles: The primary bronchi enter the lungs and further branch into secondary bronchi, which divide into tertiary bronchi. The bronchi continue to divide into smaller bronchioles, ultimately ending in microscopic structures called terminal bronchioles.
- Alveoli: At the end of the bronchioles, clusters of grape-like air sacs called alveoli are present. These thin-walled structures facilitate gas exchange between the respiratory system and the bloodstream. The large surface area of the alveoli allows for efficient diffusion of oxygen into the blood and the removal of carbon dioxide.
- Lungs: The lungs are the major organs of the respiratory system. The human respiratory system consists of two lungs – the right lung and the left lung. Each lung is enclosed by a double-layered membrane called the pleura, which helps in reducing friction during breathing.
- Diaphragm: The diaphragm is a dome-shaped muscle located beneath the lungs. It plays a crucial role in the process of respiration by contracting and relaxing, which causes changes in the volume of the thoracic cavity and assists in breathing.
Conclusion: The examination of John’s respiratory system revealed structural abnormalities, including inflammation of the bronchi and reduced elasticity of the lung tissue. The pulmonologist diagnosed John with chronic bronchitis and provided appropriate treatment to alleviate his symptoms. This case study demonstrates the significance of understanding the structural organization of the human respiratory system in diagnosing and managing respiratory disorders.
By studying the structural organization of plants and animals, such as the human respiratory system, we gain insights into how different organs, tissues, and cells work together to perform essential functions, enabling us to better understand the complexities of living organisms.
