The Cellular Level Of Organization Flashcards
What living structural and functional units enclosed by a membrane?
Cells
What process of cell division in which all cells arise, in which one cell divides into two identical cells?
Cell Division
What is the study of cellular structure and function?
Cell Biology
What is Cell Division?
It’s when one cell divides into two identical cells.
What are the 3 main parts of a cell?
Plasma Membrane, Cytoplasm, and Nucleus
What part of a cell which forms the cell’s flexible outer surface, separating the cell’s internal environment (inside the cell) from the external environment (outside the cell). It is a selective barrier that regulates the flow of materials into and out of a cell. This selectivity helps establish and maintain the appropriate environment for normal cellular activities. It also plays a key role in communication among cells and between cells and their external environment?
Plasma Membrane
What part of the cell which consists of all the cellular contents between the plasma membrane and the nucleus?
Cytoplasm
What are the 2 components of Cytoplasm?
Cytosol and Organelles
What component is the fluid portion of Cytoplasm that contains water, dissolved solutes, and suspended particles?
Cytosol
What component of Cytoplasm that has a characteristic shape and specific functions. Examples include the cytoskeleton, ribosomes, endoplasmic reticulum, Golgi complex, lysosomes, peroxisomes, and mitochondria?
Organelles
What part of the cell which is a large organelle that houses most of a cell’s DNA. Within the nucleus, each chromosome (chromo = colored), a single molecule of DNA associated with several proteins, contains thousands of hereditary units called genes that control most aspects of cellular structure and function?
Nucleus
