Does a bacterial cell have a cell membrane?
Of course they are found in bacterial cells.Every living cell has a plasma membrane.
What is the the method by which large particles and macromolecules enter the cell by an infolding of the plasma membrane?
The method by which large particles and macromolecules enter the cell by an infolding of the plasma membrane is called endocytosis. This process involves the formation of vesicles that engulf the molecules and bring them into the cell. Endocytosis includes phagocytosis for solid particles and pinocytosis for liquid molecules.
Do some bacteria not have a plasma membrane?
All bacteria have a plasma membrane, which is a semi-permeable membrane that surrounds the cell and regulates the passage of molecules in and out of the cell. The plasma membrane is essential for bacterial survival and function.
Do bacterial plasma membranes contain sterols?
Many bacterial plasma membranes do contain a sterol like membrane called hopanoids. Hopanoids are a natural pentacylic compound, this is based on the chemical structure hopane.
How does nutrients enter a cell?
The plasma membrane.

Do plant cell's animal cell's and bacterial cell's all have a plasma membrane?
Yes, all plant cells, animal cells, and bacterial cells have a plasma membrane. The plasma membrane is a semi-permeable membrane that surrounds the cell and regulates the passage of molecules in and out of the cell.

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.
In a cell what is the periplasm?
This refers to the area around the plasma membrane. In a bacterium, the area between the plasma membrane and the the bacterial cell wall.

What is the bacterial structure that acts as a selective barrier allowing nutrients to enter the cell and wastes to leave the cell.?
plasma 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.
What name is given to the rigid structure found outside the plasma membrane that surrounds and supports the bacterial cells?
The cell wall is a rigid supporting structure.
Which agents can cause injury to the bacterial plasma membrane?
There are several types of antibiotics that cause damage to the plasma membrane of bacterial cells. These antibiotics injure the the plasma membrane and cause it to die (lysis of the cell). After the membrane has been damaged or destroyed, the bacteria's contents/nurtients escape and the poisons of the antibiotic are allowed to enter the cell and kill it. Antibiotics have selective toxicity so that they can target specific microbes without damaging the person taking the drug.
