Cells

Which cell structure contains the cell's genetic material and controls the cells activities?

• organelle

• cell membrane

• cytoplasm

• nucleus

Unlike the cell membrane, the cell wall is

• found in all organisms

• made of cellulose

• made of a lipid bilayer

• a flexible barrier

Which of the following is NOT found in the nucleus?

• cytoplasm

• chromatin

• nucleolus

• DNA

Which structures carry out cell movement?

• cytoplasm and ribosomes

• cilia and flagella

• nucleus and nucleolus

• chromosomes and chromatin

Which organelle breaks down food into particles the cell can use?

• lysosome

• golgi apparatus

• endoplasmic reticulum

• mitochondria

Which of the following is a function of the cell membrane?

• breaks down carbohydrates

• stores water, salt, proteins and crbohydrates

• keeps the cell wall in place

• regulates which materials enter and leave the cell

The thin flexible layer surrounding the cell is called the

• cell wall

• cell envelope

• cell membrane

• cytoplasm

The main function of the cell wall is to

• support and protect the cell

• help the cell move

• store DNA

• direct the activities of the cell

Which of the following is a function of the nucleus?

• stores DNA

• controls most of the cells processes

• contains the information needed to make proteins

• all of these are correct

Which of the following is a function of the cytoskeleton?

• contains DNA

• surrounds the cell

• helps the cell keep its shape

• helps make protein
