cell theory - correct answer All living things are composed of cells. Cells are the basic units of structure and function in living things. New cells are produced from existing cells. prokaryotes - correct answer Cells that have genetic material that is NOT contained in a nucleus eukaryotes - correct answer Cells that contain a nucleus in which their genetic material is separated from the rest of the cell. organelles - correct answer The structures inside the cell that act as specialize...

Cell Theory - a. all organisms are composed of cells b. the cell is the basic unit of life c. cells arise from pre-existing cells Unicellular - organism with 1 cell (uni = 1) Multicellular - organism with multiple specialized groups of cells Prokaryote - no membrane-bound organelles (no nucleus) Eukaryote - has a nucleus and membrane bound organelles Plant Cells vs. Animal Cells - plants: a. rigid b. have chloroplasts (where photosynthesis occurs)

This is a summary of the inside of a cells organelles. I have information about its chemical components. There is in depth and detailed information about proteins structure and function

Cell theory Correct Answer All living things are composed of cells. Cells are the basic units of structure and function in living things. New cells are produced from existing cells. Prokaryotes Correct Answer Cells that have genetic material that is NOT contained in a nucleus Eukaryotes Correct Answer Cells that contain a nucleus in which their genetic material is separated from the rest of the cell. Organelles Correct Answer The structures inside the cell that act as specialized organs...

Theory of Endosymbiosis - Eukaryotic cells emerged when mitochondria and chloroplasts, once free-living prokaryotes, took up permanent residence inside other larger cells, about 1.5 billion years ago. Eukaryotic Cell - A type of cell with a membrane-enclosed nucleus and membraneenclosed organelles. Organisms with eukaryotic cells (protists, plants, fungi, and animals) are called eukaryotes. Prokaryotic Cell - A type of cell lacking a membrane-enclosed nucleus and membraneenclosed organ...
