During prophase,chromatin becomes chromosomes.

Osmosis and dialysis are special cases of diffusion.

DNA differs from RNA in that

Which of the following is not part of the cytoskeleton of the cell?

The process responsible for urine formation in the kidney is called dialysis.

The function of the endoplasmic reticulum depends on whether it is smooth or rough.

The molecules that stabilize the cell membrane and prevent it from breaking easily are the

Which of the following is not a function of the cell membrane?

Match the phase of mitosis with an event in that phase. -DNA replicates

The organelles that are flattened sacs that chemically process molecules are the

Ribosomes are the "protein factories" of the cells.

The function of transfer RNA is to

The Golgi apparatus is called the "protein factory."

Explain the process of translation.

The structure in the cell that controls most of the activities of the cell is the

Match each of the cell structures with its function or description. -A set of membranes that form canals that wind through the cytoplasm

Lysosomes not only digest microbes but also are involved in the process of "cell suicide" called apoptosis.

Transcription occurs at the ribosome.

After the process of diffusion establishes equilibrium,no further movement of molecules occurs.

Endoplasmic reticulum is the "digestive bag" of the cell.
