Chapter 17.1, Problem 2MI

Summary Introduction

To define:

The given term “morphology” using a book or a dictionary.

Introduction:

Scientists use the system of classification to organize all living things. Understanding classification helps us to study organisms and their evolutionary relationships. Classification allows living things to be organized according to their common characteristics and how closely they are related to each other.

Answer to Problem 2MI

Morphology refers to the structure and form of an organism or one of its parts.

Explanation of Solution

There is a great diversity of species living on planet Earth. It becomes easy for biologists to communicate and retain information about organisms when they are organized into groups. The biological system of classification is based on the diversity of species. Classification is grouping of objects or organisms based on a set of criteria.

Greek philosopher Aristotle gave the first system of classification. He classified living organisms as either plants or animals. Animals were further classified as “red blooded” or “bloodless”. Animals were also grouped according to their habitats and morphology. Plants were also grouped depending on their size and structure.
