A Detailed Comparative Cross Section Showing Both Organelles
A Detailed Comparative Cross Section Showing Both Organelles — a labelled NEET Biology diagram with a definitions lexicon.
A detailed, comparative cross-section showing both organelles side-by-side. Must label: Outer membrane, Inner membrane/Thylakoids, Matrix/Stroma, Cristae/Grana. Labelled parts: Outer Membrane, Inner Membrane, Cross-section, Mitochondrion, Chloroplast, Cristae, Stroma, Matrix, Grana, both organelles side-by-side, Thylakoids, emphasizing differences internal folding. The smooth external phospholipid bilayer of mitochondria and chloroplasts that acts as a protective barrier and is highly permeable due to porins. FYI: Porins are large protein channels that allow the free passage of molecules up to a certain molecular weight. The highly selective internal membrane of mitochondria or chloroplasts that contains the machinery for electron transport and ATP synthesis. FYI: In mitochondria, this membrane is folded into cristae to maximize the surface area available for metabolic reactions. A diagrammatic view of an organ or tissue obtained by cutting it at a right angle to its longitudinal axis. FYI: Transverse sections (T.S.) are standard in plant anatomy to study the arrangement of vascular bundles. A double-membraned semi-autonomous organelle responsible for aerobic respiration and the production of ATP via oxidative phosphorylation. FYI: Known as the powerhouse of the cell, mitochondria possess their own circular DNA and 70S ribosomes. A double-membraned plastid containing chlorophyll pigments that performs photosynthesis to convert light energy into chemical energy. FYI: Chloroplasts are found mainly in the mesophyll cells of leaves and are thought to have evolved via endosymbiosis. Infoldings of the inner membrane of the mitochondrion which increase surface area for cellular respiration. The fluid-filled space surrounding the grana inside the chloroplast. The dense fluid within the inner membrane of a mitochondrion containing enzymes and DNA. Stacks of thylakoid discs located within the stroma of the chloroplast where the light-dependent reactions of photosynthesis occur. FYI: The individual thylakoid membranes within the grana contain the pigments and proteins of Photosystem I and II. both organelles side-by-side is a key labeled feature or concept in this BioAtlas visual: Comparative diagram of Mitochondrion and Chloroplast ultrastructure, emphasizing the differences in internal folding (cristae vs grana) while maintaining common elemen...
