In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell's survival.

Is endoplasmic reticulum prokaryotic or eukaryotic?

Endoplasmic reticulum, microtubules, and the Golgi apparatus are unique to eukaryotic cells, and will not be found in prokaryotes.

Do eukaryotic cells have rough ER?

rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.

What is the function of the endoplasmic reticulum in the eukaryotic cells?

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

What does a eukaryotic cell have that prokaryotic cells do not have?

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Why is endoplasmic reticulum present in eukaryotic cells and not in prokaryotic cells?

Explanation: When comparing prokaryotes to eukaryotes, the main fact to remember is that prokaryotes do not contain membrane-bound organelles. This means they have no mitochondria, Golgi apparatus, or endoplasmic reticulum.

In which cells endoplasmic reticulum is absent?

The membranes of the ER are continuous with the outer nuclear membrane. The endoplasmic reticulum is not found in red blood cells, or spermatozoa.

Which is not related to endoplasmic reticulum?

Mitochondria is the site of energy generation. It is not generated in the endoplasmic reticulum. So, the correct answer is option C.

Do prokaryotes and eukaryotes have DNA?

Prokaryotes contain circular DNA in addition to smaller, transferable DNA plasmids. Eukaryotic cells contain mitochondrial DNA in addition to nuclear DNA. Eukaryotes separate replicated chromosomes by mitosis, using cytoskeletal proteins, whereas prokaryotes divide more simply via binary fission.

Do eukaryotic cells have a cell wall?

Cell Walls: Most prokaryotic cells have a rigid cell wall that surrounds the plasma membrane and gives shape to the organism. In eukaryotes, vertebrates don't have a cell wall but plants do.

Do prokaryotic cells have a chloroplast?

Prokaryotic cells have no chloroplasts or mitochondria. Despite this, many of them can do aerobic respiration of the same type that mitochondria do. Some can do photosynthesis the way chloroplasts do.

Which of the following is not a function of ER?

Which one of the following is not a function of Rough endoplasmic reticulum? Answer: Membrane biogenesis.

Which of these is not related to endoplasmic reticulum Class 9?

Explanation: Energy is produced in the Mitochondria hence option c is not related to Endoplasmic reticulum.

What is the only cell organelle seen in prokaryotic?

- Cell organelle: In prokaryotic cell, cytoplasm do not have organelle except ribosomes while on the other hand Eukaryotic cell, Cytoplasm contain endoplasmic reticulum, mitochondria, golgi bodies, centrosome, microtubules, microbodies, lysosomes , and also ribosomes. So, the correct answer is Ribosomes.

Why red blood cells have no endoplasmic reticulum?

The endoplasmic reticulum is absent because it reduces the surface to volume ratio which allows more RBC to accumulate. The RBC initially contains a nucleus but loses it as they mature which increases the efficiency of the cell to carry oxygen.

Why do ovary cells contain endoplasmic reticulum?

In addition, smooth endoplasmic reticulum functions in the synthesis of lipid-containing macromolecules. ... Similarly, cells of the ovaries and testes, which produce the lipid-containing hormones estrogen and testosterone, contain large amounts of smooth endoplasmic reticulum.

Is the endoplasmic reticulum in plant and animal cells?

Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER.

What is the difference between eukaryotic and prokaryotic cells quizlet?

What is the difference between Prokaryotic and Eukaryotic cells? Eukaryotic cells have a true nucleus and have membrane bound organelles, Prokaryotic doesn't. ... Both contain DNA, has a cell membrane,has cytoplasm, has ribosomes, and cell wall (eukar-plant only).

Do prokaryotes and eukaryotes have cytoplasm?

Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. ... The cytoplasm is all the contents of the cell inside the cell membrane, not including the nucleus.

Why do eukaryotic cells require mitochondria?

Mitochondria — often called the powerhouses of the cell — enable eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. That's because these organelles greatly expand the amount of membrane used for energy-generating electron transport chains.

Do both prokaryotes and eukaryotes have a cell membrane?

Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. ... An image of plasma membrane shows the phospholipid bilayer, embedded proteins, and cholesterol molecules.

In which way are a prokaryotic cell and a eukaryotic cell alike?

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

How are prokaryotic and eukaryotic cells similar?

Prokaryotic and eukaryotic cells are the same because they both have cell membranes, cytoplasm, and contain DNA. ... Prokaryotic cells store their DNA in the nucleus. Since eukaryotic cells have no nucleus, their DNA is stored in the cytoplasm.

Which of the following is a function of the endoplasmic reticulum?

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.
