Unit 15 He saw many small empty pores in the cork under the 15.6 Refraction and its microscope, and he called them “cells”, meaning small practical use rooms. He also found “cells” in other plant tissues. He - the hand lens and the was the first to use the term “cell” to denote the basic microscope unit of all living things. KS4 Biology (S4-6) I.

Cellular organisation - Discovery of cells © Times Publishing (Hong Kong) Limited -1- 10– Developing a theory for the 17 • role of cells Matthias Schleiden and Theodor Schwann put forward cell Worksheet 2 KS3 Science (S1-3) a theory about the role of cells. protozoan Schleiden proposed that all plant tissues are made up stain (1804 – 1881) of cells and each cell possesses a nucleus which is nucleus living things - Theodor Schwann the most important portion of the cell. Schwann found duplicate - Cells (1810 – 1882) that all animal and plant tissues are made up of cells, cell division - Basic structure of a cell - Rudolf Virchow which are the basic units of structure and function of cell theory - Cells can divide and (1821 – 1902) living things. - Matthias Schleiden • • • CD Track X2 3.1 The basic units of grow Rudolf Virchow further developed this idea after observing that cells of an embryo duplicated KS4 Biology (S4-6) themselves by means of cell division. He also I. Cells and Molecules of suggested that disease is no more than the response Life of cells to abnormal conditions. d. Cell cycle and division Their work led to the establishment of the cell theory, an idea that explains the relationship between cells and the organism. © Times Publishing (Hong Kong) Limited Unit 3 -2- 18– Understanding the 23 • relationship between genes and chromosomes • - Walter Sutton (1877 – 1916) Walter Sutton offered an explanation of how genes breeding experiment Worksheet 3 KS3 Science (S1-3) passed from one generation to another. gene Unit 3 He noted the parallel between the behaviours of the gamete genes and chromosomes and proposed that a chromosome characteristic is controlled by a pair of genes.
