Cells EOCT Study Guide Standard : SB1. Students will analyze the nature of the relationships between structures and functions in living cells. a. Explain the role of cell organelles for both prokaryotic and eukaryotic cells, including the cell membrane, in maintaining homeostasis and cell reproduction. Complete the venn diagram for the two types of cells: Prokaryotic All Cells Eukaryotic Label the cells with whether they are prokaryotic or eukaryotic. If eukaryotic is the organelle a plant or animal? Complete the organelle portion of your vocabulary and label the organelles. You may need to make the pictures larger to see the organelles. b. Explain how enzymes function as catalysts. Use your cells vocab sheet to answer the above statement. c. Identify the function of the four major macromolecules (i.e., carbohydrates, proteins, lipids, nucleic acids). Compare the composition and functions of the four major groups of biological macromolecules by completing the table below. Group Proteins Nucleic acids Carbohydrates Lipids Composition Function d. Explain the impact of water on life processes (i.e., osmosis, diffusion). Complete the organizer for material transport with the following words and fill in your own descriptions where needed: Passive transport Diffusion Osmosis Facilitated Diffusion Isotonic Hypertonic Material Transport Active Transport (Uses ENERGY) Endocytosis Exocytosis (NO ENERGY) Description: Movement of particles from an area of high concentration to an area of lower concentration Description: Movement of materials across the plasma membrane using proteins Description: Diffusion of water across a selectively permeable membrane from high to low concentration. Hypotonic Substance diffuse at the same rate Describe each property of water. Cohesion Adhesion Surface Tension Polar High heat capacity Less dense as a solid than a liquid Water diffuses into the cell Water diffuses out of the cell Description: Process by which the cell surrounds and takes particles into the cell Description: Secretion of material out of the plasma membrane
