General Biology 1: Cell Theory and Historical Development

These flashcards cover the vocabulary, key scientists, historical dates, and the three fundamental principles of cell theory based on the General Biology 1 lecture notes.

Cell

The basic structural and functional unit of life.

Structural unit

The concept that living things are built from cells.

Functional unit

The concept that life processes happen inside cells.

Zacharias Jansen (1590)

He constructed the first simple microscope with only one set of lens.

Robert Hooke (1665)

Observed thin cork using a microscope and called the tiny box-like spaces "cells."

Anton/Antonie van Leeuwenhoek (1670)

Used powerful single-lens microscopes to observe living microorganisms in water and other samples.

Matthias Schleiden (1838)

A scientist who studied plant tissues and concluded that plants are made of cells.

Theodor Schwann (1839)

A scientist who studied animal tissues and concluded that animals are made of cells.

Rudolf Virchow (1855)

A scientist who stated that cells come from pre-existing cells, rejecting the idea that cells appear from nothing.

Crystallization method

An idea proposed by Matthias Schleiden that new cells arise from old cells or from elsewhere via this process.

First part of Cell Theory

All living things are made of one or more cells.

Second part of Cell Theory

The cell is the basic unit of structure and function of life.

Third part of Cell Theory

All cells come from pre-existing cells.

Secondary source

A resource that summarizes or explains information from original studies, books, or historical records.
