Cells are tiny Summarize the relationship between the surface-area-to-volume ratio of a cell and its size. Higher the ratio of service to internal volume, the faster the exchange of materials with the environment, small cells most likely to have adequate surface area for exchanging waste and nutrients Recognize the key components of the cell plasma membrane. Boundary between outside and inside of a cell, gatekeeper, regulate its passage of molecules and ions into and out of the cell Explain how the plasma membrane regulates the passage of molecules into and out of the cell. Phospholipid by layer with embedded proteins, Describe the diverse functions of the proteins embedded in the plasma membrane. Channel proteins - form tunnel across entire membrane, allowing only one or few types of specific molecules to move across
the membrane Identify the characteristics common to all cells. Plasma membrane, cytoplasm, DNA Distinguish between prokaryotic and eukaryotic cells. Prokaryotic has flagellum, eukaryotic cell does not. Eukaryotic cell has nucleus, prokaryotic cells do not. Identify the structures of a prokaryotic cell. Capsule, nucleoid, ribosome, plasma membrane, cell wall, cytoplasm, flagellum Recognize the role of the nucleus in cellular activities. Stores genetic information and ribosomes in cytoplasm use info to carry out menu facture of proteins State the components of the endomembrane system and list their functions. Endoplasmic reticulum - Identify the energy rolls that chloroplasts and mitochondria play in a cell. Chloroplast - location where carbon dioxide gas, water, and energy from sun used to produce carbohydrates Mitochondria - powerhouse of cell, produce most of the ATP cell utilizes Relate the specific components of the cytoskeleton to their diverse roles within the cell. Extends from the nucleus to plasma

Support cell, meshwork of fibrous proteins and polysaccharides in close association with the cell that produced them Distinguish among the types of junctions present between eukaryotic cells. Adhesion junction - internal cytoplasmic Plaques, firmly attached to the cytoskeleton within each cell Tight junctions - plasma membrane proteins attached to each other, producing a zipper like fastening Gap junctions - two identical plasma membrane channels join Sets with similar termsBIS 10: Chapter 4 (Inside the Cell)33 terms HBug1997 Unit Four: Cell Biology Test71 terms aubreyw13 Unit 2 Cell Structure and function53 terms connie__h Life Science Chapter 2 Cell Structure and Function75 terms Joel_Schultz Sets found in the same folderBiology: Cell Division50 terms WeAreTheOnes Unit 19 terms adriennestrother Physiology Exam 3 pt. 130 terms ajsneed23 Chapter 1 Objectives { Anatomy and Physiology 1 }14 terms msheetsmccn Other sets by this creatorBio Chapter 8 study cards17 terms sierra_smith21 Chapter 5 study cards6 terms sierra_smith21 Bio Chapter 3 Study cards6 terms sierra_smith21 Bio Chapter 2 study cards11 terms sierra_smith21 Verified questions

As such, it controls passage of various molecules—including sugars, amino acids, ions, and water—into and out of the cell.
Which of the following allows the passage of small ions and molecules between adjacent cells?Gap junctions are specialized connections that form a narrow pore between adjacent cells. These pores permit small molecules and ions to move from one cell to another.
What allows the passage of small molecules and ions between cells in animals?Cell junctions are intercellular structures with multiprotein complexes that provide contact, communication, and/or adhesion between neighboring cells in animals. Gap junctions are bridges between cells for sharing small molecules or ions for rapid intercellular communication. Its functional unit is called connexon.
Do plant cells allow passage of small molecules?Introduction. Plasmodesmata (Pd) are co-axial membranous channels that cross walls of adjacent plant cells, linking the cytoplasm, plasma membranes and endoplasmic reticulum (ER) of cells and allowing direct cytoplasmic cell-to-cell communication of both small molecules and macromolecules (proteins and RNA).
