6) Statistical and quantitative observations of individual mt- and pt-nuclei made it possible to study the dynamic behavior of organelle
division during the cell cycle of non-sexual reproduction and to study cytoplasmic (maternal, paternal and biparental) inheritance of organelle
genomes (DNAs) during sexual reproduction (Fig.

The image drawn as 3-D helps to remind the student that cells are not flat, and better represents the size and shape of each organelle
Sreelatha explains that ion channels are pores in the membranes of cells or of organelles
within cells that allow regulated passage of small molecules or ions across membranes.
Mitochondria are minute organelles
inside living cells, floating apart from the nucleus in the cytoplasm.
The resulting functional enzyme complex, made of a nontoxic polymer, "almost mimics an organelle
," says Yunfeng Lu, a professor of chemical and biomolecular engineering at the University of California, Los Angeles, who led the research with Cheng Ji, a professor of biochemical and molecular biology at the University of Southern California.
However, I do like his analogies, especially the mangrove tree of life and his description of the relationship between a cell and its organelles
as rooms aboard a ship.
Furthermore, a family of calcium-dependent cysteine proteases--calpains--occur in abundance in the lens and play a crucial role in organelle
degradation and programmed cell death [29-31].
Lysakowski and her colleagues were interested in a part of the cell called the striated organelle
, which lies underneath this cuticle plate and is believed to be responsible for its stability.
Fun Fact: This structure is an organelle
, or specialized unit of a cell, commonly found in plants.
For the purpose of this book, an organelle
is a distinct entity within the cell that performs a particular function as a compartmentalization of enzymes.
This is achieved using a combination of engineering and/or selection of strains which: do not express certain enzymes which create the undesirable complex structures characteristic of the fungal giycoproteins, which express exogenous enzymes selected either to have optimal activity under the conditions present in the fungi where activity is desired, or which are targeted to an organelle
where optimal activity is achieved, and combinations thereof wherein the genetically engineered eukaryote expresses multiple exogenous enzymes required to produce "human-like" glycoproteins.
T-cells failed to internalize either of the particulates and showed no organelle
or nuclear changes.
Microtubules and microfilaments coordinate to control a unique fountain pattern of organelle
streaming within the elongating cell tip.
SemBioSys founder and chief scientific officer, at the University of Calgary to increase the understanding of how oleosins are targeted to oilbodies, the natural oil storage organelle
