WELCOME TO THIS GREAT EDUCATIONAL BLOG

Welcome to my Pre-Nursing Exam Prep blog. I hope it will help you prepare very well for the Pre-NLN entrance exam, popularly known as the PAX exam. This is one of the entrance exams required by some schools for those who want to pursue careers in the nursing field in the USA. I will attempt to break down the review materials into manageable parts so that you can systematically and efficiently prepare for the test with less stress. I will guide you to prepare for the entire content of the test. Hopefully, you will be able to pass after going through these series.


BEST OF LUCK!

WHAT IS BOTANY?

What is botany?
It is one of the branches of biology that deals with the study of plants.

  • What kinds of plants?
  • How they live and grow.
  • How they respond to their environment.
  • The diseases they are susceptible to, and how they can be cured.
  • How they influence our everyday lives.
Branches of botany

There are many branches of botany. This includes:
  • Taxonomy: Deals with the classification of plants
  • Morphology: Studies the form and structure of plants (anatomy, cytology, embryology)
  • Physiology: Concerned with the life processes of plants and functions of the different organs and tissues.
  • Pathology: Deals with the diseases of plants.
  • Ecology: Deals with the relations of plants to their surroundings
  • Paleobotany: Also known as fossil botany, deals with plants of past geological periods.
  • Plant Genetics: Deals with the study of heredity in plants.
Other areas of intensive study include:
  • Bacteriology: Study of bacteria
  • Mycology: Study of fungi
  • Algology: Study of algae
  • Bryology: Study of mosses and liverworts
