Eukaryote cells include a variety of membrane-bound structures, collectively referred to as the endomembrane system. Simple compartments, called vesicles or vacuoles, can form by budding off other membranes. Many cells ingest food and other materials through a process of endocytosis, where the outer membrane invaginates and then pinches off to form a vesicle. It is probable that most other membrane-bound organelles are ultimately derived from such vesicles.
The nucleus is surrounded by a double membrane (commonly referred to as a nuclear envelope), with pores that allow material to move in and out. Various tube- and sheet-like extensions of the nuclear membrane form what is called the endoplasmic reticulum or ER, which is involved in protein transport and maturation. It includes the rough ER where ribosomes are attached to synthesize proteins, which enter the interior space or lumen. Subsequently, they generally enter vesicles, which bud off from the smooth ER. In most eukaryotes, these protein-carrying vesicles are released and further modified in stacks of flattened vesicles, called Golgi bodies or dictyosomes.
Vesicles may be specialized for various purposes. For instance, lysosomes contain enzymes that break down the contents of food vacuoles, and peroxisomes are used to break down peroxide, which is toxic otherwise. Many protozoa have contractile vacuoles, which collect and expel excess water, and extrusomes, which expel material used to deflect predators or capture prey. In multicellular organisms, hormones are often produced in vesicles. In higher plants, most of a cell's volume is taken up by a central vacuole, which primarily maintains its osmotic pressure

What is the differacne between prokaryotic and a eukarotic cell?
A prokaryotic cell does not have cell organelles bound inside a nuclear membrane, i.e., it does not have a proper nuclear structure. It has a primitive nucleus. On the contrary, a eukaryotic cell has a well developed nucleus with membrane bound organelles.
Where is the cytoplasm found in?
Cells Cytoplasm is found inside the plasma membranes of prokaryotic bacteria cells and eukaryotic animal cells. It is inside the cell membrane which is adjacent to the cell wall in eukaryotic plant cells.
Which contains chromosomes?
Chromosomes are the molecules of DNA (inheritable genetic material) in each of your cells. Human cells are eukaryotic meaning that they have membrane bound organelles. The chromosomes in eukaryotic cells are enclosed within a nuclear membrane, collectively known as the nucleus. The nucleus is one of the organelles inside a eukaryotic cell.
Does a prokaryotic cell have a cell membrace?
Yes.Both Prokaryotic Cells and Eukaryotic Cells have an outer cell membrane.But, prokaryotic cells do not have membranes around their organelles (inside the cell), whereas eukaryotic cells do.
What organelle includes everything inside the plant cell besides the nucleus?
The cytoplasm contains all the organelles inside of the cell membrane except the nucleus.
Which term describes a tiny membrane-bounded structure inside a eukaryotic cell?
organelles

What is the structure of a generalized eukaryote cell?
Cytoplasm (inside a cell membrane) surrounding a nucleolus (which is inside its own membrane).
Where is the cytoplasm found in?
Cells Cytoplasm is found inside the plasma membranes of prokaryotic bacteria cells and eukaryotic animal cells. It is inside the cell membrane which is adjacent to the cell wall in eukaryotic plant cells.
Structure inside eukaryotic cells that have different functions within the cell are known as what?
Organelle
What structure protects the nucleus and the information inside of it?
nuclear membrane
. The inside of a membrane bilayer is .?
The cell membrane's bilayer structure is made up of phospholipids.
A structure within a eukaryotic cell that carries out specific activites inside the cell is called?
nucleus
Which contains chromosomes?
Chromosomes are the molecules of DNA (inheritable genetic material) in each of your cells. Human cells are eukaryotic meaning that they have membrane bound organelles. The chromosomes in eukaryotic cells are enclosed within a nuclear membrane, collectively known as the nucleus. The nucleus is one of the organelles inside a eukaryotic cell.
What is the definition of a eukaryotic cell?
A cell with a double walled membrane bound nucleus and many membrane bound organelles. and a large two sided face.
What keeps DNA in the nucleus which is enclosed by its own membrane?
Its called the eukaryotic cell.
Which structure regulates passage of molecules into and out of cells?
The cell membrane is a membrane separating the inside of the cell from the outside environment. This structure is also known as the plasma membrane or the cytoplasmic membrane.
