Unit 4 Exam Review

This organelle controls what enters/leaves a cell.

• cell membrane

• Nuclear membrane

• cell wall

You can distinguish a prokaryote apart from a nucleus by--

• The presence of a nuclear membrane

• The presence of a cell membrane

• The presence of DNA

This organelle takes food and turns it into ATP (ENERGY) for plant and animal cells.

• Chloroplast

• Mitochondria

• Ribosome

Proteins are produced at this organelle.

• golgi body

• ribosome

• mitochondria

This organelle is the site of many cellular reactions, including protein and lipid synthesis. It can be rough or smooth. It transports proteins to the golgi.

• endoplasmic reticulum

• mitochondria

• nucleus

This organelle packages and distributes proteins.

• golgi body

• chloroplast

• ribosomes

Choose the statement below that is TRUE.

• Plant and animal cells both have cell walls so the cell can maintain its shape.

• Animal cells do not have chloroplasts because animals do not require the use of photosynthesis to produce their food.

• Plant cells do not have a nucleus because plants are not living organisms like animals are.

During what phase of the cell cycle is DNA replicated?

• G1 phase

• S phase

• M phase

Which sequence of DNA bases would pair with this partial strand

CAT TCA CTG

• ATG TGA CAG

• TAC ACT GTC

• GTA AGT GAC

In what phase of mitosis do the chromosomes line up in the middle of the cell?

• Telophase

• Metaphase

• Prophase
