What else can I help you with?
What controls which substances can move in and out of cells?
Cell membrane controls which substances can move in and out of a cell. It is the dynamic boundary of cell
Is a big cell better than a small cell?
no, because motor proteins would have to work harder to move substances and organelles.
What is a complex molecule that is embedded in the cell membrane that helpss move substances move into and out of a cell?
Transport protein
Which part of a plant allows certain substances to move in and out of the cell?
the cell membrane
Are many short hair-like structures on the surface of the cell that help move the cell or move substances past the cell?
cilia
What does a plasma membrane protein do?

What is The plasma membrane helps to maintain a cells what?
The plasma membrane helps to maintain homeostassi within the cell by allowing substances to move in and out of the cell the plasma membrane is used to maintain homeostasis within the cell by allowing substances to move in and out of the cell
What projections allow the cell to move or moves substances along the surface of the cell?
Projections that allow the cell to move or to move substances along the surface of the cell are called cilia and flagella. Flagella is a single long hair that allows the cell to swim. Cilia are several projections used for movement across the cell surface.
What substances need to penetrate to all parts of a living cell?
Substances such as nutrients, oxygen, and water need to penetrate all parts of a living cell to support its metabolic processes and maintain its function. Waste products and signaling molecules also need to move throughout the cell for proper communication and waste removal.
What Controls what moves into cells?
The Cell Membrane is usually attributed with controling which substances can move in and out of the cell.
