Chloroplasts are a type of plastid that are distinguished by their green color, the result of specialized chlorophyll pigments. Jun 14, 2025 · Cells consist of a variety of internal and external structures that perform specialized functions necessary for survival and reproduction. In plants, chloroplasts occur in all green tissues. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. May 12, 2025 · A neuron is a nerve cell that processes and transmits information through electrical and chemical signals in the nervous system. Neurons consist of a cell body, dendrites (which receive signals), and an axon (which sends signals). Cell theory, developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all organisms, and that all cells come from pre-existing cells. A cell is a mass of cytoplasm that is bound externally by a cell membrane. A cell is a membrane-bound organelle that has other cell organelles, which perform different functions. Synaptic connections allow communication between neurons, facilitating the relay of information throughout the body. 23 hours ago · Name and definition of the cell structure Learn with flashcards, games and more — for free. It functions as a barrier, keeping cell constituents in and unwanted substances out, and as a gate, allowing transport into the cell of essential nutrients and movement from the cell of waste products. Dec 30, 2025 · Cells help in the formation of the structure of an organism. A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.
