Chapter 13 study guide 1. In the absence of targeting information‚ what is the default location of proteins synthesized by cytosolic ribosomes? 2. Two membrane-bound organelles that are responsible for making and modifying proteins are? ER and Golgi- newly synthesized secretory proteins are first targeted to the ER‚ where they are folded and modified before exported to the Golgi for sorting 3. Name a few cytoplasmic proteins. 4. Name a few secretory proteins. Plasma membrane proteins

Name: Jojo Cohen Date: 12-8-17 Cell Transportation Overview Directions: Read page 362-374 and use your notes to help you answer the following questions. 1. Illustrate and describe the structure of the cell membrane using figure 2.8 on page 362. 2. What does selectively permeable mean (pg. 363)? A: Selectively permeable means that some substances can pass through the cell membrane while others cannot pass through. 3. What is diffusion and why does it occur? A: The movement of solutes

Jane Watson Glandular epithelial tissue: Glandular epithelial cells make up any glands within the body. These include sebaceous glands of the skin and glands in the intestinal lining (exocrine glands)‚ and many of the endocrine glands releasing hormones‚ such as the thyroid follicle.

plant cell would mainly help the cell take in water or get rid of water‚ just like the potato did? This is also known as “osmosis.” How do you know that this organelle would help with that process? Vacuole 5) Which organelle‚ if empty‚ would cause the plant to wilt? Why is this? if the vacuole is empty the plant will because the water and the plant. 6) Name an organelle that you see in the plant cell that you did not see in the animal cell.

Little Celleste the cell was in the middle of his meal‚ when he thought for a minute about what he was eating‚ and how it had gotten there. The great Father Cellmas came to his mind‚ so he called out for him because he knew he could solve his answers. Since after all Father Cellmas was the man who knew all the questions you asked him about yourself. Father Cellmas was in the middle of a nap when he heard the yell of a small cell. “I wonder who is calling for me?” Father Cellmas wonders‚ and gets

be crucial to a plants health. In an isotonic solution‚ a plant cell has no net movement of water. A word for what occurs is flaccid. When solution is isotonic the vacuole is not full and that is really bad because a plant needs its nutrients and a full vacuole makes it stand tall (turgar pressure). In a hypertonic solution‚ the vacuoles lose water; the cytoplasm shrinks and chloroplast are seen in the center of the cell. A word that describes this is plasmolysis. This is bad for a plant cell because

The Effect of Solvent Exposure and Temperature on Beet Cell Membrane Integrity Introduction: • Cell membranes are vital to proper cellular function • Cell membranes consist of a lipid bilayer made up of phospholipids • Phospholipids are amphipathic molecules meaning they have a dual nature in that they show both hydrophilic (water-loving) and hydrophobic (water-fearing) properties • The amphipathic nature of phospholipids causes them to spontaneously form bilayers in water
