Describe the makeup of the nuclear membrane.

Has two lipid bilayers that separate the nucleus from the cytoplasm.

When does eukaryotic DNA wind up into chromosomes?

When a cell is about to divide.

What are ribosomes made of?

A dozen different proteins as well as RNA.

What is the role of the endoplasmic reticulum in the cell?

It moves proteins and other substances through the cell.

A small, membrane-bound sac that transports substances in cells.

Differentiate between the functions of the rough endoplasmic reticulum and the smooth endoplasmic reticulum.

The rough helps transport the proteins that are made by its attached ribosomes, and the smooth makes lipids and breaks down toxic substances.

What is the role of the Golgi apparatus?

They modify the proteins that are received in vesicles from the ER.

What is the role of lysosomes in the cell?

They contain the cell's digestive enzymes and help with the production, packaging, and distribution of proteins.

List four things lysosomes digest and recycle.

Proteins, nucleic acids, lipids, and carbohydrates.

What is made in the mitochondria and why is it important?

Energy, and it is important because it is the main energy of the cells.

Describe the inner membranes on the mitochondria.

It is folded, and it has a compartment in which the chemical reactions that produce ATP during cell metabolism take place.

What is one theory about why mitochondria have their own DNA.

Primitive prokaryotes are the ancestors of mitochondria.

List the three structures found in plant cells but not in animal cells.

Cell wall, several chloroplasts, and a central vacuole.

What is the role of the cell wall? What polysaccharide makes it up?

It supports and protects the cell, and cellulose makes it up.

What happens in chloroplasts? Do they have their own DNA?

They use light energy to make carbohydrates from carbon dioxide and water, and they have their own DNA.

What does the central vacuole do and why is it important to the plant cell?

It stores water and may contain many substances, including ions, nutrients, and wastes. It creates rigidity which helps the plant stand up.
