CELL STRUCTURE AND FUNCTION

The Cell Theory states

• all living things are made of cells

• the cell is the basic unit of life

• cells are produced from other cells

• all of the above

The structures that synthesize proteins in cells are the

• ribosomes

• Golgi apparatus

• lysosomes

• vacuoles

The dark spot seen in the nucleus in non-dividing cells where RNA for ribosomes is made is called the

• cristae

• nucleolus

• plastids

• cytosol

Which two molecules are used to make cell membranes?

• carbohydrates and glycogen

• polysaccharides and nucleic acids

• phospholipids and starch

• phospholipids and proteins

• nucleic acids and lipids

Cells like muscle cells which require lots of energy would probably have many

• nuclei

• flagella

• mitochondria

• lysosomes

Mitochondria store the energy released when they burn glucose as

• DNA

• ATP

• SER

• RNA

THE cell wall of a plant is composed of

• cellulose

• carbohydrates

• lipids

• lipoprotein

 

Which invention played the biggest role in the discovery of cells by early scientists?

• magnifying glass

• eyeglasses

• lens

• compound microscope

Specialized structures that work together inside a cell are called

• organelles

• eukaryotes

• prokaryotes

• nuclei

Unlike a eukaryotic cell, a prokaryotic cell does not have

• DNA

• cytoplasm

• a cell membrane

• a nucleus
