What organelle helps to protect and support the cell?

Which organelles support and protect the cell?

The cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting. It also keeps large, damaging molecules out of the cell. Plastids are membrane-bound organelles with their own DNA.

What provides support and protects the cell?

The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell.

What are the organelles that have a protective function?

A membrane called the nuclear envelope surrounds the nucleus, and its job is to create a room within the cell to both protect the genetic information and to house all the molecules that are involved in processing and protecting that info.

What do lysosomes do?

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. … They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

What organelle is covered with ribosomes and surrounding the nucleus?

Endoplasmic reticulum: The ER is a network of tube-like membranes continuous with the nuclear envelope. Part of it are “rough” because they are covered in ribosomes, while other parts are “smooth” because they aren’t.

What does the Golgi apparatus do?

A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.

What do ribosomes do?

Ribosomes are the sites in a cell in which protein synthesis takes place. … Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule.

What organelles work together to give structure and support in animal cells?

Cytoskeleton. The cytoskeleton is the framework of the cell. It consists of microtubules and microfilaments that give structure to the cell and allow for the movement of vesicles and other components around the cell.

What structures protect the cell?

The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.

What is the role of cell organelles in the cell?

Organelles are small structures within the cytoplasm that carry out functions necessary to maintain homeostasis in the cell. They are involved in many processes, for example energy production, building proteins and secretions, destroying toxins, and responding to external signals.
