Biology Chapter 3 Vocab
Word | Definition | Clue | Cell Theory | A theory that states that all organisms are made of cells, all cells are produced by other living things, and the cell is the most basic unit of life. | | Cytoplasm | A jellylike substance that contains dissolved molecular building blocks- such as proteins, nucleic acids, minerals, and ions. | | Organelles | Structures that are specialized to perform distinct processes within a cell. | | Prokaryotic Cells | Cells that do not have a nucleus or other membrane-bound organelles. | | Eukaryotic Cells | Cells that have a nucleus and other membrane-bound organelles. | | Cytoskeleton | A network of proteins that is constantly changing to meet the needs of a cell. | | Nucleus | The storehouse for most of the genetic information, or DNA, in your cells. | | Endoplasmic Reticulum | (Or the ER) is an interconnected network of thin folded membranes. | | Ribosomes | Are tiny organelles that link amino acids together to form proteins. | | Golgi Apparatus | The Golgi apparatus consists of closely layered stacks of membrane-enclosed spaces that process, sort, and deliver proteins. | | Vesicles | Are a general name used to describe small membrane-bound sacs that divide some materials from the rest of the cytoplasm and transport these materials from place to place. | | Mitochondria | Mitochondria supply energy to the cell. They are bean shaped and have two membranes. | | Vacuole | A vacuole is a fluid-filled sac used for the storage of materials needed by a cell. | | Lysosomes | The lysosomes are membrane-bound organelles that contain enzymes. | | Centrioles | Centrioles are cylinder-shaped organelles made of short microtubules arranged in a circle. | | Cell Wall | The surrounding of a cell membrane in a plant cell. It is a rigid layer that gives protection, support, and shape to the cell. | | Chloroplasts | Chloroplasts are organelles that carry out photosynthesis, a series of complex
