small structures in cells that make proteins ribosomes

Which organelle is a series of folded membranes?

Endoplasmic reticulum (ER):

What organelle looks like a maze?

Mitochondria looks like a maze full of DNA and ribosomes.

Which organelle is rod shaped with inner folded membranes?

Mitochondria Structure

Why is inner membrane of mitochondria folded?

To increase the capacity of the mitochondrion to synthesize ATP, the inner membrane is folded to form cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion.

Which organelle does not have membranes?

Non-membrane bound organelles are more solid structures that are not fluid-filled, so they have no need for a membrane. Examples of non-membrane bound organelles are ribosomes, the cell wall, and the cytoskeleton.

What is an example of a membrane bound organelle?

Eukaryotic cells contain many membrane-bound organelles. The organelles include the nucleus, endoplasmic reticulum, Golgi apparatus, vacuoles, lysosomes, mitochondria, and, in plants, chloroplasts.

What cell structures do eukaryotic cells have?

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)

What are the membrane bound structures in a cell called?

An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell.

What are internal membranes?

Internal membranes facilitate cellular processes by minimizing competing interactions and by increasing surface area where reactions can occur. Archaea and Bacteria generally lack internal membranes and organelles and have a cell wall.

Why are internal membranes important?

How is RER different from Ser?

The main difference lies between the SER and RER is the presence of ribosomes, as SER do not have ribosomes but RER have ribosomes. SER mainly produce and export lipids and protein and function for detoxification, while RER produces, secrete and export proteins and few hormones.
