Quick Answer: What organelles inside the cell have membranes with many convolutions? Why?

Why do cell membranes have many convolutions?

Small cells are better able to transport materials in and out of a cell more efficiently. Many convolutions increase the surface area of the cell, thus allowing for more interactions between the cell and its environment.

Why does the Golgi apparatus have many convolutions?

This organelle is a highly folded membrane. The many folds result in more surface area for ribosomes to attach and thus allowing protein synthesis to occur at a more efficient rate.

Which organelle contains the most membrane?

The nucleus, the largest organelle in eukaryotic cells, is surrounded by two membranes, each one a phospholipid bilayer containing many different types of proteins.

What organelles does the cell membrane interact with?

These structures do exchange membrane material, however, via a special type of transport. Today, scientists know that the endomembrane system includes the endoplasmic reticulum (ER ), Golgi apparatus, and lysosomes. Vesicles also allow the exchange of membrane components with a cell’s plasma membrane.

Why do cells have cell membranes?

All cells have cell membranes. Cell membranes are selectively permeable. This allows for movement of select substances from the outside to the inside of the cell and from inside the cell to the outside of the cell. The most fundamental role of the cell membrane is to protect the cell.

Will water move in or out of the cell?

In general, net movement of water into or out of cells is negligible. In such situations, water still moves across membranes by simple diffusion, but the process is important enough to warrant a distinct name – osmosis.

What does the Golgi apparatus do?

The Golgi apparatus transports and modifies proteins in eukaryotic cells. How have scientists studied dynamic protein movements through the Golgi? The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.

How are highly folded membranes an advantage?

A highly folded membrane is an advantage for the function of celluar parts because is divides pieces in the cell, creatimg an easier transportation route. An organelle with highly folded membranes is the endoplasmic reticulum.

Why do mitochondria have convolutions?

The inner membrane is folded and convoluted which allows for a greater surface area to utulize for the electron transport chain. These convolutions are what make up the cristae.

Is the plasma membrane an organelle?

The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell. The plasma membrane is made up of two layers of phospholipids (phospholipids bilayer).

Which organelle is like the brain of a cell?

For example, the nucleus acts like a brain for the cell, issuing commands and controlling cellular activities. Organelles are often enclosed by a lipid bilayer membrane.

Which organelle is used in cell repair?

Lysosomes. Lysosomes are organelles that digest macromolecules, repair cell membranes, and respond to foreign substances entering the cell.

How do organelles interact within the cell?

The cytoplasm is a water-based substrate makes up the interior of the cell and surrounds the organelles. It fills the spaces between organelles and helps the cytoskeleton move protein-carrying vesicles around the cell from the endoplasmic reticulum to the Golgi complex and the plasma membrane.

What is the main function of ribosome?

Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r- proteins ).

What are 2 organelles that work together?
