Flashcards

Scientific Method

A step-by-step approach used by scientists to understand and explain natural phenomena. It includes observing, asking questions, forming hypotheses, conducting experiments, analyzing data, and drawing conclusions. This systematic method emphasizes testing hypotheses with empirical evidence.

Microscopy in Biology

Microscopes are powerful tools that allow us to magnify and visualize tiny structures that are invisible to the naked eye, like cells or bacteria. There are different types of microscopes, like light microscopes and electron microscopes, each with varying capabilities for magnification and resolution.

Cells - Basic Unit of Life

The fundamental building blocks of all living organisms. They are self-contained units that carry out all life processes necessary for survival, such as metabolism, growth, and reproduction.

Biological Diversity

The variety of life forms on Earth. It is categorized using a hierarchical system that groups organisms based on shared characteristics. Kingdoms, like plants, animals, fungi, and bacteria, are broad categories within this classification system.
