Chapter 1 Cell Theory- in the 18th century‚ two scientists came up with the cell theory. Schleiden and Schwen. 3 corollaries of the cell theory: -all cells are alike in chemical composition -all cells store and process information in the same way -all cells arise from other cell through cell division 5 types of different Microscopes 1. Light Microscope- produces 2-D image Direct descendants of Hooks scope> take two lenses to a light source> used this to magnify images up to 1‚000 fold.

Explain how the advance in technology allowed the progressive accumulation of knowledge and understanding of the cell theory The technological advancements‚ in the scientific field‚ have opened opportunities for scientists to accumulate knowledge and understanding of the cell theory and have thus provided justification to the living organisms that exist. Notably‚ prior to the proposal of the cell theory‚ limited knowledge and understanding of what humans comprised of was evident and thus the theory of

Report Comparing Animal and Plant Cells The cell is the fundamental structural unit of all living organisms. Cells help carry out the functions of life and together support the organism to function as a whole. Cells are divided into two main categories of eukaryotes and prokaryotes. Animal cells and plant cells fall into the division of eukaryote cells that have both a nucleus and organelles. In this lab‚ animal and plant cells will be compared through a microscope to identify differences in the

Some of you have been asking for clarification regarding your optional use of the MSAF‚ the student self-reporting absence form. As you may know‚ this is allowance that you are permitted to use once per term to address temporary illnesses and deadline pressures. The allowance provided is generally five days‚ but faculty are asked to specify how the MSAF is to be applied in their particular course. Here are my guidelines: For all other more serious illnesses and absences‚ you would follow the

Page 1 of 8 BIOLOGY 12- CELL STRUCTURE & FUNCTION Chapter Notes THE CELL THEORY • Although different living things may be as unlike as a violet and an octopus‚ they are all built in essentially the same way. The most basic similarity is that all living things are composed of one or more cells. This is known as the Cell Theory. • our knowledge of cells is built on work done with microscopes • English scientist Robert Hooke in 1665 first described cells from his observations of cork slices
