SCIENCE Looking Inside the Cell Name: ____________________________ Period # ____ Date: ____/____/____ Pages 17 - 22 Cell Wall Physical Description: _____________________________ ________________________________________________ ________________________________________________ Job Description: _________________________________ ________________________________________________ ________________________________________________ Cell Membrane Physical Description: _____________________________ ________________________________________________ ________________________________________________ Job Description: _________________________________ ________________________________________________ ________________________________________________ Nucleus (all parts) Physical Description: ________________________________ ___________________________________________________ ___________________________________________________ Job Description: ____________________________________ ___________________________________________________ ___________________________________________________ ___________________________________________________ Nuclear Envelope Physical Description: The membrane that is surrounding the ! ! ! nucleus. Job Description: Protects the nucleus, allowing only certain materials to pass into or out of the cell. Chromatin (DNA) Physical Description: Thin Strands of genetic material. Job Description: Contains instructions for directing all of the cell’s functions. Nucleolus Physical Description: Small objects floating in the nucleus. Job Description: This is where ribosomes are made Mitochondria Physical Description: Rod-shaped structures Job Description: Known as the “powerhouse of the cell because they convert food into energy that the cell uses to carry out it’s activities. Endoplasmic Reticulum Physical Description: A maze of passageways. Job Description: Passageways carry proteins from one part of the cell to another. Ribosomes Physical Description: Small, grain-like bodies that are either floating freely in the cytoplasm, or are attached to the endoplasmic reticulum. Job Description: Produce proteins for growth and repair of the cell. Golgi Body Physical Description: Looks like flattened sacs and tubes. Job Description: The cell’s mailroom. It packages proteins with other materials and distibute them throughout the cell. Chloroplasts Physical Description: ________________________________ ___________________________________________________ ___________________________________________________ Job Description: ____________________________________ ___________________________________________________ Vacuoles Physical Description: Large water-filled sac(s) floating in the cytoplasm Job Description: Store food and other materials needed by the cell Lysosomes Physical Description: Small, round structures floating in the cytoplasm. Job Description:Break down large food particles. also break down old cell parts into substances that can be used again. Cytoplasm Physical Description: A clear, thick, gel-like fluid found between the nucleus an the cell membrane. Job Description: Constantly moving, carrying organelles with it. SCIENCE Name: ____________________________ Period # ____ Date: ____/____/____ Animal Cell Plant Cell SCIENCE Name: ____________________________ Period # ____ Date: ____/____/____ Physical Description ____ Cell Wall (p. 17) A. In cells with cell walls (plants) it is located just inside the cell wall. In cells without cell walls (animals) is a boundary that separates the cell from it’s environment. ____ Cell Membrane (p. 17) B. Large green structures floating in the cell’s cytoplasm. Found only in the cells of plants (and some algae). ____ Nucleus (p. 18) C. A rigid layer of nonliving material that surrounds the cells of plants that is mostly made of a strong material called cellulose. ____ Chloroplasts (p. 22) D. A large oval structure inside the cell. Job Description ____ Cell Wall (p. 17) ____ Cell Membrane (p. 17) A. Act as the “brain of the cell. controlling all the activities of the cell. B. Helps to protect and support the cell. Materials, including water and oxygen can pass through it easily ____ Nucleus (p. 18) C. Controls what goes in and out of the cell: Food and oxygen enter, Harmful waste products leave. ____ Chloroplasts (p. 22) D. Capture energy from sunlight and use it to produce food for the cell.
