Who is Robert Hooke? This scientist was the first to use these instruments (called microscopes) because of his great skill of grinding lenses Who is Leewenhoek? This was Virchow’s contribution to the Cell Theory. What is that all cells come from preexisting cells; plant cells come from plant cells and animal cells come from animal cells? This was Schwann’s contribution to the Cell Theory. What is that cells are the basic unit of life? These are the three parts of the cell theory. What is 1. Cells are the basic unit of life 2. All living things are made up of one or more cells 3. All cells come from preexisting cells? These are three examples of organelles. Various answers. This is the semi-jelly like environment in which most of the cell’s activities take place. What is the cytosol? (cytoplasm) This organelle only occurs in the plant cell – and provides support for the cell What is the cell membrane? This is the name of the organelle where the process of photosynthesis takes place and contains a green pigment called chlorophyll. What is the Chloroplasts? These ballonlike spaces within the cytoplasm store waste and food and other substances the cell cannot use right away. What are vacuoles ? This type of cell makes its own food thorough photosynthesis and moves by using 2 long whiplike “flagella”. What is a Chlamydomonas? This type of cell has no cell wall, a nucleus, and mitochondria. What is a animal cell? Two differences between plant and animal cells. What is plants have a cell wall, and chloroplasts that animal cells do not have? This organelle provides energy for the muscle cells in the human body What is Mitochondria These are the three parts of the cell theory. What is 1. Cells are the basic unit of life 2. All living things are made up of one or more cells 3. All cells come from preexisting cells?? This is the function of the nucleus. What is it controls all of the functions of the cell? This is the function cell wall. What is support? This tough material makes cell walls thicker and more rigid than cell membranes. What is cellulose? These green pigment absorbs sunlight. What is chlorophyll ? This organelle distributes materials such as oxygen and food to different parts of the cell. What is Cytoplasm ? This word was formed when cork was observed by Robert Hooke. What is cellulae (cell) ? This word “cellulae” translated means. What is little rooms? This type of microscope uses two lenses. What is Compound Light Microscopes? This part of the microscope controls the amount of light reaching the object being viewed. What is Diaphram ? This part of the microscope is used with medium and high power magnification to bring the object into focus. What is fine adjustment knob ? This is the basic unit of every system. What is the cell ? This is the type of cell shown to the right. What is a plant cell? These are 5 characteristics of living organisms. What is living organisms need – 1. Need energy 2. Respond and adapt to their environment 3. Reproduce 4. Grow 5. Produce wastes Scientists measure the size of cells in this unit. What is micrometre ? This unicellular organism sweeps food into its mouth by using cilia. What is paramecium?
