The idea that protoplasm of eukaryotes is simply divisible into a ground substance called "cytoplasm" and a structural body called the cell nucleus reflects the more primitive knowledge of cell structure that preceded the development of electron microscopy, when it seemed that cytoplasm was a homogeneous fluid and the existence of most sub ...
The cytoplasm describes all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles [1] and excluding the nucleus in eukaryotic cells. The material inside the nucleus of a eukaryotic cell and contained within the nuclear membrane is termed the nucleoplasm .
Nucleoplasm is quite similar to the cytoplasm, with the main difference being that nucleoplasm is found inside the nucleus while the cytoplasm is located inside the cell, outside of the nucleus. Their ionic compositions are nearly identical due to the ion pumps and permeability of the nuclear envelope, however, the proteins in these two fluids ...
The eukaryotic DNA is organized in one or more linear molecules, called chromosomes, which are associated with histone proteins. All chromosomal DNA is stored in the cell nucleus, separated from the cytoplasm by a membrane. [2] Some eukaryotic organelles such as mitochondria also contain some DNA. Many eukaryotic cells are ciliated with primary ...
One observation was from very thin slices of bottle cork. Hooke discovered a multitude of tiny pores that he named "cells". Hooke discovered a multitude of tiny pores that he named "cells". This came from the Latin word Cella , meaning ‘a small room’ like monks lived in, and also Cellulae , which meant the six-sided cell of a honeycomb.
Sometimes, however, the choices aren't as varied as the brand names might indicate. Some companies practice "multibranding," running apparently competing brands within the same industry to soak up ...
One approach involves the introduction of Lugol's iodine solution, which effectively immobilizes the cytoplasmic streaming. [ citation needed ] Alternatively, the compound Cytochalasin D , dissolved in dimethyl sulfoxide , can be employed to achieve a similar effect by disrupting the actin microfilaments responsible for facilitating cytoplasmic ...
