What is the structure that surrounds a cell and controls what enters and leaves the cell?

The cell membrane is the structure that surrounds a cell and controls what enters and leaves the cell. It is made up of a lipid bilayer with embedded proteins that selectively allow certain molecules and ions to pass through the membrane.


What is the outermost structure of a plant cell?

The outermost structure of a plant cell is a cell wall. Plant cells have cell walls for extra protection as they cannot move like animals and protists, whose outermost cell structure is the cell membrane, a thinner protective cover.


What makes proteins in a cell structure?

Proteins in a cell provide structure by forming filaments and networks that help maintain cell shape and integrity. They also contribute to the structure of organelles within the cell, such as the cytoskeleton and cell membrane. Additionally, proteins play a role in cell adhesion and cell-to-cell communication, which are essential for maintaining tissue structure and function.


A plant cell has a structure that keeps its shape very rigid What structure has this purpose?

The structure in a plant cell that provides rigidity and maintains the cell's shape is the cell wall. The cell wall is made up of cellulose fibers that provide structural support and protect the cell from mechanical stress.


What structure serves to provide strength and support to the plant cell?

Support and structure of plant cells is primarily derived from the cell wall. This is a semi-permeable rigid structure surrounds each cell (on the outside of the cell membrane).Secondary support comes from the (fluid filled) vacuoles within each cell, which provide "turgor pressure".The cell wallExplanation...The cell wall is a strong, rigid structure that surrounds, protects and gives shape to plant cells.------------------------------------------------------------------
