What else can I help you with?
What controls the passage of molecules in and out of the cell?
Cell membrane controls the passage of molecules in and out of the cell through selective permeability. This allows specific molecules to pass through while preventing others from entering or exiting the cell. The cell membrane contains protein channels and pumps that regulate the movement of ions and molecules.
Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What does protoplasm contains?
Protoplasm contains various organic and inorganic molecules necessary for the functioning of a cell, such as proteins, lipids, carbohydrates, nucleic acids, ions, and water. It also contains cellular organelles that help in carrying out specific functions within the cell.
What specific cell part is all remains of the cell?
The cell membrane is the specific cell part that encloses and contains all the remains of the cell, protecting its contents and regulating the entry and exit of molecules.
What is designated as the cytoplasm?
The cytoplasm is the gel-like substance within a cell where organelles are suspended. It contains various molecules, proteins, and nutrients essential for cell function.
Which part of the cell surrounds the cell and allows molecules in and?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What does the cell wall help with?
1) holds in the molecules that allow the cell to function (to be alive). 2) keeps out most foreign molecules. 3) "contains" transport molecules that move specific molecules in and out.

The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
The cell membrane contains lipid molecules that?
The cell membrane contains lipid molecules that provide a barrier to the free movement of ions into and out of the cell.
A chromosome contains many genes that are transcribed into different what?
A chromosome contains many genes that are transcribed into different RNA molecules. These RNA molecules can serve as templates for protein synthesis or have other functions in the cell.
How many DNA molecules are present in a sperm cell?
A sperm cell contains 23 chromosomes, each made up of a single DNA molecule. Therefore, a sperm cell typically contains one copy of each chromosome, with a total of 23 DNA molecules.
What important molecules does the nucleas contain?
The nucleus contains the DNA for that cell. Without the DNA, the cell cannot grow and develop fully.
What are on chromosomes in a nucleus of a cell?
The cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes. Each human cell contains roughly two meters of DNA.
What organelle breaks down food into molecules the cell can use?
The organelle that breaks down food into molecules the cell can use is the lysosome. It contains enzymes that break down large molecules into smaller components that can be used by the cell for energy or building materials.
Does molecules have cell?
No, molecules do not have cell, rather a cell have molecules in it.
