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.

What is the definition if endocytosis?
Endocytosis is a cellular process in which cells engulf molecules or particles by wrapping them in a section of the cell membrane to form a vesicle. This allows the cell to take in substances from the extracellular environment. Endocytosis plays a key role in nutrient uptake, cell signaling, and the removal of waste products.
What is the difference between endosymbiosis and invagination?
Endosymbiosis refers to the engulfment of a prokaryotic cell that developed into an organelle, whereas invagination refers to the membrane folding in on itself and forming membranous organelles.
Which cell component forms pinocytic vesicles?
Plasma membrane is the cell component that forms pinocytic vesicles through the process of endocytosis. Pinocytic vesicles are small membrane-bound vesicles formed by invagination of the plasma membrane to bring in extracellular fluids.
What are 5 Mechanism of cellular exchange?
Passive diffusion: Movement of small, non-polar molecules across the cell membrane. Facilitated diffusion: Movement of specific molecules through protein channels in the cell membrane. Active transport: Movement of molecules against the concentration gradient using energy from ATP. Endocytosis: Uptake of large molecules or particles by the cell through invagination of the cell membrane. Exocytosis: Release of molecules or waste from the cell by fusion of vesicles with the cell 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 is the definition ofendocytosis?
The official definition for the word ofendocytosis is "the taking in of matter by a living cell by invagination of its membrane to form a vacuole."
What is the definition Endocytosis?
The official definition of the word endocytosis is "the taking in of matter by a living cell by invagination of its membrane to form a vacuole."
What is the theory of invagination?
Plasma Membrane invaginates in a multiple genome containing cell.
Were does the Golgi apparatus come from?
it is believed that the Golgi apparatus originated by invagination of the plasma membrane.

When was Artificial Invagination created?
Artificial Invagination was created on 1990-09-23.
Is the correct definition of Power of a test (Note Ho null hypothesis Ha alternative hypothesis)?
No, that is not the correct definition.
What is the science definition of hypothesis?
A hypothesis is a reasonable answer based on what you know and what you observe.
What does arbuscular do?
well Arbuscluar mycorrhizal fungi extend branching hyphae through the root cell wall into tubes formed by invagination of the root cell plasma membrane
Which cell component forms pinocytic vesicles?
