Name: ____________________________________Date:______________________Block:_______ Vocabulary: Unit 4 Cell Processes Vocabulary Word Diffusion Osmosis Passive Transport Endocytosis Exocytosis Definition The movement of particles from an area where their concentration is high to an area where their concentration is low. The diffusion of water across a cell membrane. The diffusion of particles through proteins in the cell membrane from areas where the concentration of particles is high to areas where the concentration is low. The process in which a cell membrane surrounds a particle and encloses it in a vesicle to bring it into the cell. The process used to remove large particles from a cell, during exocytosis, a vesicle containing the particles fuses with the cell membrane. Selectively Permeable Cell membranes allow some things to pass through but not others. Equilibrium Even distribution of particles. Example or Sentence Picture Vocabulary Word ATP Photosynthesis Cellular Respiration Cell Cycle Mitosis Binary Fission Meiosis Definition Adenosine Triphosphate; molecule that provides energy for the cell’s activities (released from glucose in cellular respiration). The process by which plants capture light energy from the sun and convert it into sugar. The process of producing ATP from oxygen and glucose releases carbon dioxide as a waste product. The life cycle of a cell, in eukaryotes it consists of chromosome duplication, mitosis and cytokinesis. The nuclear division in eukaryotic cells in which each cell receives a copy of the original chromosomes. Simple cell division in which one cell splits into two – used by bacteria. The division of sex cells in eukaryotes. Example or Sentence Picture
