Quotes & Sayings About Cytoplasm

The importance of the egg's non-nuclear material - the cytoplasm - in early development is apparent in the consistent relation that is seen to exist between certain regions in the cytoplasm of a fertilized egg and certain kinds or directions of cell differentiation. — John Gurdon

school you may have learned the basic components of a cell: the nucleus that contains genetic material, the energy-producing mitochondria, the protective membrane at the outside rim, and the cytoplasm in between. — Bruce H. Lipton

Except for the rare cases of plastid inheritance, the inheritance of all known cofactors can be sufficiently accounted for by the presence of genes in the chromosomes. In a word the cytoplasm may be ignored genetically. — Thomas Hunt Morgan

Nuclear transplantation is a technique that has enormously facilitated the analysis of these interactions between nucleus and cytoplasm. — John Gurdon

Metabolically active cells, such as those of the liver, kidneys, muscles, and brain, have hundreds or thousands of mitochondria, making up some 40 per cent of the cytoplasm. The egg cell, or oocyte, is exceptional: it passes on around 100000 mitochondria to the next generation. In contrast, blood cells and skin cells have very few, or none at all; sperm usually have fewer than 100. All in all, there are said to be 10 million billion mitochondria in an adult human, which together constitute about 10 per cent of our body weight. — Nick Lane

The nucleus has to take care of the inheritance of the heritable characters, while the surrounding cytoplasm is concerned with accommodation or adaptation to the environment. — Ernst Haeckel

That wasn't a true dream, but an ancient organic memory millions of years old. The innate releasing mechanisms laid down in your cytoplasm have been awakened. The expanding sun and rising temperatures are driving you back down to the spinal levels into the drowned seas of the lowest layers of your unconscious, into the entirely new zone of the neuronic psyche. This is the lumbar transfer, total psychic recall. We really remember these swamps and lagoons. — J.G. Ballard

Our brains are wired to interpret shapes as faces and bodies. That's why people see the Virgin Mary in the clouds or even in cheese sandwiches. It's your cytoplasm, not some strange ectoplasm. — Seth Shostak
