cell parts

Question 1

Mitachondria?

Answer 1

Mitochondria provide the cell with energy. In a process called respiration, mitochondria release energy by combining sugar molecules with oxygen to form carbon dioxide and water. This energy is used in almost every other function of the cell.

Question 2

Ribsomes

Answer 2

Proteins are put together on ribosomes using information from the nucleus and molecules from the cytoplasm. Proteins are large molecules that are needed for cell growth, for repair and for reproduction.

Question 3

Endoplasmic reticulum?

Answer 3

A series of folded membranes, called endoplasmic reticulum, carry materials through the cytoplasm. “Rough” endoplasmic reticulum has many ribosomes attached to it.

Question 4

Golgi body?

Answer 4

Proteins are stored inside the Golgi apparatus. This organelle also puts proteins into packages called vesicles. Vesicles carry the protein molecules to the surface of the cell, where they are released to the outside. The proteins in the vesicles vary, depending on their function.

Question 5

Lysosomes?

Answer 5

Lysosomes patrol the cytoplasm, cleaning up. They contain special proteins that are used to break down large molecules into many smaller molecules. The smaller molecules can be reused as building blocks for other large molecules. In humans and other animals, lysosomes are also used to kill and digest invading organisms.
