The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Fungal cells and some protist cells also have cell walls.
What cell is for protection and structure?
1. The part of a cell that provides structural support and protection is the Cell wall.
Which organelle is responsible for protecting the cell?
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
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.
Which part of the cell provides structural support and protection?
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 is the organelle of protects DNA?
The nucleus is surrounded by a membrane called the nuclear envelope, which protects the DNA and separates the nucleus from the rest of the cell.
Which organelle provides a protective covering to the cell and controls what enters and leaves quizlet?
The outer covering of all cells that controls what enters and leaves the cell. Also called “plasma membrane” or phospholipid bilayer.
Which organelle protects a cell and regulates what goes in and comes out of the cell?
Smooth E.R. Cell Membrane A double layer that supports and protects the cell. Allows materials in and out. Lysosome Contains digestive enzymes that destroy damaged organelles and invaders.
What is the mitochondria structure?
Mitochondria have an inner and outer membrane, with an intermembrane space between them. The outer membrane contains proteins known as porins, which allow movement of ions into and out of the mitochondrion. The inner membrane contains a variety of enzymes. …
What does a ribosome do?
A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.
What is the function of the ribosomes?
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 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 cells have a Golgi apparatus?
Quick look: Golgi apparatus(or complex, or body, or ‘the ‘Golgi’) is found in all plant and animal cells and is the term given to groups of flattened disc-like structures located close to the endoplasmic reticulum.
