Biology Notes 1. Organisms are made of cells that have similar structural characteristics. 1 Outline the historical development of the cell theory‚ in particular the contributions of Robert Hooke and Robert Brown. The development of the cell theory starts in the 1600ʼs with Robert Hookeʼs discovery of cells when viewing a piece of cork under a microscope and describing them as a nun house. Anton van Leeuwenhoek was crucial in the development of microscopes making simple microscopes through advanced

After Hooke‚ a Dutch scientist named Anton van Leeuwenhoek used the light microscope to observe living cells inside stagnant rain water. This then developed the cell theory in which all living

have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell

Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter.
