Quotes About Organelles

Inside the "cells" there were no normal-looking organelles, no nuclei, endoplasmic reticulum, mitochondria, or Golgi bodies.

Within every cell in your body is a posse of organelles (or miniature organs) called mitochondria

The cell contains highly organized physical structures, called intracellular organelles.

I became aware of the very complex internal organization in a cell from the basic science classes, and it made me think about how all that could work. It seemed like a great mystery, especially how organelles in the cell can be arranged in three dimensions, and how thousands of proteins could find their way to the right location in the cells.

The same make of organelles functions in the cells of mice and men; the same make of contractile protein serves the motion of amoeba and of the pianist's fingers; the same four chemical units constitute the alphabet of heredity throughout the animal and plant kingdoms-only the words are different for every creature.

The integrative powers of life are manifested in the phenomena of symbiosis between organelles, in the varied forms of partnership within the same species or between different species; in the phenomena of regeneration, in lower species, of complete individuals from their fragments; in the re-formation of scrambled embryonic organs, etc. The self-assertive tendency is equally ubiquitous in the competitive struggle for life.

One mitochondrion contains tens of thousands of copies of each respiratory complex. A single cell contains hundreds or thousands of mitochondria. Your 40 trillion cells contain at least a quadrillion mitochondria, with a combined convoluted surface area of about 14,000 square metres; about four football fields. Their job is to pump protons, and together they pump more than 1021 of them – nearly as many as there are stars in the known universe – every second.

The Jedi thought of the cellular organelles as symbionts, but to Plagueis midi-chlorians were interlopers, running interference for the Force and standing in the way of a being's ability to contact the Force directly.

action, and there are also structures so distinct from the rest of the cell 'jelly', like cells within cells, that the best explanation of their presence is that that is indeed what they are. These semi-autonomous 'cells within the cell' are called organelles. As we saw in Chapter Four, Lynn Margulis has explained how the ancestors of the organelles used to be separate, bacteria

Your 40 trillion cells contain at least a quadrillion mitochondria, with a combined convoluted surface area of about 14,000 square metres; about four football fields.

It seems that all eukaryotic cells either have, or once had (and then lost) mitochondria. In other words, possession of mitochondria is a sine qua non of the eukaryotic condition
