Unit 2 Test Review - Cells

How does the cell membrane use the ATP produced by the cell's mitochondria?

• to replace damaged phospholipids

• to produce receptors for hormones

• to move water into or out of the cell

• to transport ions against their concentration gradient

Which organelles must work together to provide food and energy to a plant cell?

• chloroplast and mitochondria

• cell membrane and cell wall

• mitochondria and vacuole

• chloroplast and vacuole

Which organelles differentiate plant cells from animal cells?

• flagella and nuclei

• mitochondria and ribosomes

• cell walls and large central vacuoles

• contractile vacuoles and cell membranes

Plant cells are able to produce their own food. This process happens in which structure?

• cell wall

• chloroplast

• mitochondria

• vacuole

Newly made proteins are modified in which organelle?

• lysosome

• endoplasmic reticulum

• mitochondria

• nucleus

A student uses a microscope to observe a cell that has a cell wall, a plasma membrane, and circular DNA. What kind of cell is it?

• plant cell

• animal cell

• eukaryotic cell

• prokaryotic cell

In which organelle is DNA found in a eukaryotic cell?

• nucleus

• vacuole

• Golgi Apparatus

• smooth endoplasmic reticulum

In a multicellular organism, the lungs are responsible for exchanging gases with the organism's environment. Which cellular structure performs the same task for a cell?

• chloroplast

• mitochondria

• plasma membrane

• nucleus

Which organ system performs the same job for a multicellular organisms as a lysosome performs for a cell?

• digestive system

• excretory system

• respiratory system

• circulatory system

A saltwater plant is placed in fresh water. What will most likely happen to the cells of the plant?

• the cell wall will prevent water from flowing

• the cells will lose water and shrivel

• the cells will gain water and swell

• the cells will stay the same size
