2 Marks

VSAQ-1 : Who is popularly known as father of botany? What was the book written by him?

  1. The Father of Botany is Theophrastus, a Greek philosopher and scientist who succeeded Aristotle.
  2. His significant work is the book titled “Historia Plantarum” (On the History of Plants). In this comprehensive work, he meticulously documented and classified a wide range of plants from his era, establishing the groundwork for the scientific discipline of botany.

VSAQ-2 : Who are Herbalists? What are the books written by them?

  1. Herbalists are specialized experts in medicinal plants and their applications for health and healing.
  2. Herbals, written by herbalists, are informative books that detail medicinal plants, their properties, and traditional uses in treating ailments. Examples include “De Materia Medica” by Dioscorides and “Herbarum Vivae Eicones” by Otto Brunfels.

VSAQ-3 : Why is Mendel considered as the father of genetics?

  1. Gregor Mendel is hailed as the “Father of Genetics” due to his pioneering work on inheritance and hybridization experiments with pea plants.
  2. In 1866, Mendel published groundbreaking research that outlined the fundamental principles of inheritance, now known as Mendelian laws. His discoveries included the principles of segregation and independent assortment, which serve as the foundation of modern genetics.
  3. Initially overlooked, Mendel’s work gained recognition among later scientists who realized the profound significance of his findings. His contributions have since become the cornerstone of genetics, revolutionizing our understanding of heredity and enabling further advancements in the field.

VSAQ-4 : Who discovered the cell and what was the book written by him?

  1. The discovery of the cell is credited to the Dutch scientist Antonie van Leeuwenhoek, who made significant advancements in microscopy during the 17th century.
  2. However, the foundational work on the cell theory is often attributed to Matthias Schleiden, a German botanist, and Theodor Schwann, a German zoologist. They formulated the cell theory in the mid-19th century.
  3. The influential book associated with the cell theory is “Microscopical Researches into the Accordance in the Structure and Growth of Animals and Plants”, which was published in 1839 by Theodor Schwann. This book laid the groundwork for our modern understanding of cells and their role in living organisms.

VSAQ-5 : What is Palaeobotany? What is its use?

  1. Palaeobotany is a scientific branch focused on studying fossilized plants from ancient geological eras.
  2. The study of palaeobotany offers valuable insights into past vegetation, aiding our understanding of plant evolution across geological time. It enables the reconstruction of ancient environments, exploration of historical climate changes, and the tracing of plant species’ evolutionary history.
  3. Palaeobotany plays a pivotal role in unraveling Earth’s history and the development of plant life on our planet, making it an indispensable field of study for researchers.

VSAQ-6 : Name the branches of botany which deal with the chlorophyllous autotrophic thallophytes and non-chlorophyllous heterotrophic thallophytes.

  1. Phycology: This botanical branch is dedicated to the study of chlorophyllous autotrophic thallophytes, specifically algae. Phycologists delve into various aspects of algae, encompassing morphology, anatomy, physiology, ecology, and taxonomy.
  2. Mycology: Mycology is the botanical discipline that focuses on the examination of non-chlorophyllous heterotrophic thallophytes, which are fungi. Mycologists explore diverse facets of fungi, including their structure, reproduction, classification, ecology, and their interactions with other organisms.

VSAQ-7 : Which group of plants is called vascular cryptogams? Name the branch of botany which deals with them?

  1. Vascular cryptogams is the term used to describe the group of plants known as pteridophytes. These are seedless vascular plants that rely on spores for reproduction and dispersal.
  2. Pteridology is the specialized branch of botany dedicated to the study of pteridophytes. Pteridologists delve into various aspects of ferns, horsetails, and clubmosses, including their morphology, anatomy, life cycle, diversity, and classification.

VSAQ-8 : Which group of plants is called amphibians of plant kingdom? Name the branch of botany which deals with them.

  1. Bryophytes are often referred to as the amphibians of the plant kingdom due to their characteristics. They are non-vascular plants that rely on water for reproduction and are commonly found in moist or aquatic habitats.
  2. Bryology is the specialized branch of botany that is dedicated to the study of bryophytes, including mosses, liverworts, and hornworts. Bryologists investigate various aspects of these plants, such as their structure, life cycle, ecology, and evolutionary history.
