PHS - Ch. 5 Cells

A semipermeable outer covering of a cell with holes that acts as its doors and windows

(has holes and pores that acts as the cell's doors and windows)

• cell membrane

• cytoplasm

• vacuole

• ribosomes

An organelle that allows larger enzymes and waste molecule packages to pass through the cell membrane

(like doors of the loading dock)

• vacuole

• ribosome

• Golgi apparatus

• lysosomes

A semifluid structure contained within the walls of a cell in which chemical reactions take place

• cytoplasm

• endoplasmic reticulum

• nucleus

• nucleolus

The organelle that contains genetic material and controls the cell's activity

(like the factory's main office)

• nucleus

• nucleolus

• vacuole

• mitochondria

The organelle located at the center of the nucleus, which uses ribosomes to build proteins

(like the factory manager)

• nucleus

• nucleolus

• mitochondria

• lysosome

Organelles that build proteins for the cell; may be free in the cytoplasm or attached to rough endoplasmic reticulum

(like assembly teams)

• ribosomes

• vacuoles

• lysosomes

• mitochondria

The organelle that moves ribosomes in an out of the nucleus as they are assembled

(like a conveyer belt on a production floor, moving construction materials (ribosomes) in and out of the cell)

• endoplasmic reticulum

• mitochondria

• vacuole

• Golgi apparatus

Which type of endoplasmic reticulum is covered with ribosomes from the nucleus for building proteins

• rough endoplasmic reticulum

• smooth endoplasmic reticulum

Which type of endoplasmic reticulum is responsible for building and storing fat and carbohydrates and detoxifies harmful substances?

• rough endoplasmic reticulum

• smooth endoplasmic reticulum

An organelle made up of layers of membrane in the cytoplasm; inspects, sorts, and packages proteins for use within or removal from the cell. (the mailing room of the cell)

• Golgi apparatus

• ribosomes

• vacuoles

• lysosomes
