Why is the color of the cells different under different conditions Be sure the hypothesis takes the role of the plasma membrane into consideration?
The color of cells can vary under different conditions due to changes in the permeability and functionality of the plasma membrane, which regulates the movement of ions and molecules in and out of the cell. For example, under stress conditions, the plasma membrane may become more permeable, allowing the entry of certain dyes or indicators that bind to specific cellular components, thus altering the perceived color. Additionally, variations in metabolic activity and the expression of pigments or proteins can also influence cell color, reflecting the cell's physiological state.

What are the currently accepted hypothesis of membrane structure referred to as?
The currently accepted hypothesis of membrane structure is the fluid mosaic model. This model describes the cell membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that are free to move laterally within the membrane. It emphasizes the fluidity and flexibility of the membrane.
How can you get membrane protein from E. coli?
To extract membrane proteins from E. coli, you can use different methods such as cell fractionation techniques, detergent extraction, or sonication. Once the membrane proteins are extracted, they can be further purified using methods like chromatography or gel electrophoresis. It is important to maintain proper conditions during extraction to ensure the stability and functionality of the membrane proteins.
Would both plant and animal cells have the same effect if the cell membrane burst?
yes it would because........ nothing is different about the function and structure of the cell membrane so in both cells the conditions of the cell membrane exploding will still be the same for both cell types (it will leak by therefore killing it)
How is the inner membrane of a chloroplast different from the outer membrane?
A highly speacialised that transports protein
What are three different names for the cell membrane?
Plasma membrane, phospholipid bilayer, fluid mosaic membrane.

What is the hypothesis to be answered for the osmosis and diffusion lab?
The hypothesis for an osmosis and diffusion lab could be: "If a semipermeable membrane is placed between two solutions of different concentrations, then water will move from the side with lower solute concentration to the side with higher solute concentration, resulting in a net movement of water through the membrane."
What is the Definition of membrane invagination hypothesis?
The membrane invagination hypothesis assumes that the prokaryotic cell membrane folded in on itself so thmbrane was formed. This double membrane is common in the organalles of eukaryotic cells. The DNA becomes attached to one such infolding resulting in a presursor of the nucleus. Later this infolding enclosed DNA within interacellular sac forming the primordial nucleus.
How is the cell membrane and nuclear membrane different?
i think its different by the way it looks
How does the membrane different from the nuclear membrane?
They do not differ much. The proteins in each are slightly different.
Archaea and eubacteria were found to be most different because?
Archaea and eubacteria are most different in terms of their cell membrane structure, as archaea have unique membrane lipids, and their genetic machinery, which is more similar to eukaryotes than bacteria. These differences reflect distinct evolutionary lineages and adaptations to different environments.

Why antibiotics act on bacterial cytoplasmic membrane but not mammilian cytoplasmic membrane?
maybe because, the structure of cytoplasmic membrane of mammilian is different from the bacteria. It is may allowed by the presence of different antigen in its membrane.

yes it would because........ nothing is different about the function and structure of the cell membrane so in both cells the conditions of the cell membrane exploding will still be the same for both cell types (it will leak by therefore killing it)
What is the autogenic hypothesis of the origin of the eukaryotic cell?
Autogenic means produced from within, or self-generating. Therefore the 'autogenic hypothesis' is most likely to be that the organelles and structures of a Eukaryotic cell were self-generated by a Prokaryotic cell - and this is how Eukaryotic cells were created. The theory of Endosymbiosis is much more widely accepted.
What three conditions are needed for osmosis to occur?
Three conditions are needed for osmosis to occur: a semipermeable membrane that allows only water molecules to pass through, a difference in solute concentration on either side of the membrane, and a gradient in water concentration across the membrane.
What evidence supports the hypothesis that the nuclear envelope of eukaryotes arose from infolding of the plasma membrane?
Evidence supporting this hypothesis includes observations that both the nuclear envelope and plasma membrane have a similar lipid composition and protein structure, as well as the presence of nuclear pores that are thought to have evolved from invaginations in the ancestral plasma membrane. Additionally, studies on the dynamics of nuclear envelope formation during cell division provide further support for the idea that the nuclear envelope originated from invaginations of the plasma membrane.
