PPT-The Vertebrate Eye Unit 1 Cells and Proteins

Advanced Higher Biology Miss Aitken The Vertebrate Eye In the eye of all vertebrates there is a structure called the retina The retina contains two types of photoreceptor cells Photoreceptor cells are cells that detect and respond to light.

Mid 1600’s: scientists use microscopes to observe living things. . 1665, Englishman Robert Hooke. Used an early compound microscope. Before we begin, . what are . organelles. ?. Cells organelles. If we have “organs”, cells have …. Organelles: Specialized parts of the cell . . . . with specific functions. Cells organelles. Cell. Regarded as the basic structural and functional unit of life.. Cell is a mass of cytoplasm enclosed by a plasma membrane consisting of certain organelles besides the nucleus or nuclear material, capable of self replicating..

How do organelles in a cell compare to organs in the human body? . Learning Target . “I can” analyze the difference between a prokaryotic cell and a eukaryotic cell. . a hierarchy of life from cells to ecosystems.. HIERARCHY OF LIFE. HIERARCHY OF LIFE. Cell: smallest functional unit of life. Ex. Heart cell (cardiac muscle cell). Tissue: made of similar cells that have the same function. Light microscopes are commonly used in classrooms. Living cells can be examined. The downfall is that they do not magnify a tremendous amount. . 2. Magnification. . is the ratio of an object’s image to its real size. A light microscope can magnify effectively to about 1,000 times the real size of a specimen. . DNA structure. In 1952, scientist Rosalind Franklin discovered that DNA is two chains of molecules in a spiral form. The actual model of DNA was made by James Watson and Francis Crick.. DNA model.

Some cells are able to reproduce and make copies of themselves by following this sequence of events. The cell cycle consists of 2 phases: interphase (not dividing) and mitosis (dividing).
