Kingdom Protista. A. Sometimes not considered a true kingdom because the organisms vary tremendously from one to another. The only universal characteristic among the group is that they are all eukaryotic.. TSW – Recognize that the presence of a nucleus determines whether a cell is prokaryotic or eukaryotic. 6.12B. Cells. There are two . basic types . of cells. Prokaryotes. or prokaryotic cells . Eukaryotes. 2.3.1, 2.3.2: Liver cell. 2.3.3: Electron micrograph of liver cell (rat). Glycogen. 2.3.4: Prokaryotic VS Eukaryotic cell. FEATURE. Prokaryotic cell. Eukaryotic cell. DNA. Naked DNA. DNA associated. with proteins. Reece . Andonov. Lizzie . Codina. Period 3. Nucleus . vs. Prison Warden. Found in both types of eukaryotic cells. The nucleus is like the prison warden because the warden controls all aspects of the prison and the nucleus controls all functions of the cell, also they are both the most important..

Sometimes not considered a true kingdom because the organisms vary tremendously from one to another. The only universal characteristic among the group is that they are all eukaryotic.. 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. What happens when cells divide? . Just like people have phases of development,. Cells have phases too.. In somatic (body) cells, a parent cell produces 2 daughter cells.. The purpose of mitosis is for growth and repair of tissue.. Three Phases or Stages. Two Basic Types. Remember….cells are the basic unit of life for ALL living things.. There are two basic types of cells:. Prokaryotic cells . – found in bacteria. Eukaryotic cells . – found in . Prokaryotic . Cell. The . term prokaryote is derived from the Greek word- . “prokaryote”. meaning before nuclei. . Prokaryotic . cells are simpler and smaller than the eukaryotic cells. . These cells lack membrane bound organelles. . Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. 1. WHAT MOLECULES?. LOCALIZING MOLECULES. 1. WHAT MOLECULES?. 2. WITH RESPECT TO WHAT?. LOCALIZING MOLECULES. 1. WHAT MOLECULES?. 2. WITH RESPECT TO WHAT?. . SPACE: Relative to other molecules, the genome, organelles, cells, tissues, whole organisms.. A primary transcript . is the initial, linear, RNA copy of a transcription unit—the segment of DNA between specific initiation and termination sequences. . The primary transcripts of both prokaryotic and eukaryotic . AP Biology. Mrs. Gionta. SC9. The Microscopic World of Cells. Cells are marvels of complexity. Trillions of cell in human body. Many specialized types. Main tool for exploration--Microscope. Microscopes as Windows on the World of Cells.
