PPT-Chapter 6 “The Cell”

Chapter 6 The Cell Life is Cellular Cell Theory All living things are made up of cells Cells are the basic units of structure amp function in living things New cells are produced from existing cells. And 57375en 57375ere Were None meets the standard for Range of Reading and Level of Text Complexity for grade 8 Its structure pacing and universal appeal make it an appropriate reading choice for reluctant readers 57375e book also o57373ers students Cell theory. Cell organization and homeostasis. Studying cells – microscopy and fractionation. Eukaryotic vs. prokaryotic cells. Compartments in eukaryotic cells (cell regions, organelles). Cytoskeleton. By Becky . The Cell. Cytology. is the study of the structure and functions of cells.. The cell was first discovered by Robert Hooke while viewing a dried cork.. The cells have been researched for 175 years.. Leaving Certificate Biology. Higher Level. Selective Permeability. Cell membranes are selectively permeable meaning they can control what enters and leaves the cell. Selective permeability is controlled by proteins embedded in the cell membrane. Why do cells need to divide?. Growth and development. You started as 1 cell and now you’re made up of roughly 40 TRILLION cells. Repair and regeneration of tissue. Reproduction.

Robert Hooke examined slices of cork under a . . microscope . and decided to call the . ‘. pore-like. ’. . . structures . cells. .. Robert Hooke, through his observations, had discovered . All organisms are made of cells. Cell structure is correlated to cellular function. All cells are related by their descent from earlier cells. The Fundamental Units of Life. to study cells. Though usually too small to be seen by the unaided eye, cells can be complex. AP Biology Exam Review. Apoptosis = cell suicide. Cell is dismantled and digested.
