I'm pretty sure it's called chromatin
Move large particles into the cell
Proteins allow the cell to reproduce. On the proteins, Carbohydrate chains "tag" a cell so that other cells can determine its type. Proteins also allow large molecules to be transported in and out of a cell.
The structures that enable cells to live and reproduce are the organelles. The organelles of a cell are like the organs found inside the human body.
A mutation.
proteins are absorbe din form of little particles.
Sometimes.
Not everything, no. It depends on the cell, some cell membranes are permeable to water (called osmosis) but not smaller particles like proteins. Whereas, some are permeable to proteins and other small particles but not to larger particles.
Endoplasmic Reticulum
Ribosomes
Without them you will die. They allow cells to reproduce and they also help you grow tall.
nucleic acid
macromolecules
active transport
they die
A ligand is a molecule that binds itself to another molecule and helps transport particles using gated channel proteins.
