Bio-U2- interim study guides-Cell

A student observes a cell under a microscope. She sees a cell wall and a nucleus. What type of cell is she observing?

• eukaryotic animal cell

• eukaryotic plant cell

• prokaryotic cell

• bacterial cell

A scientist is studying a cell that has a rigid cell wall with many hair-like projections on the outer surface. The genetic material is not enclosed by a membrane. Which cell is the scientist observing?

• cheek cell

• leaf cell

• blood cell

• a bacterial cell

Which structure is only found in eukaryotic cells?

• DNA

• mitochondrion

• plasma membrane

• ribosomes

Which structures could be common to both prokaryotic and eukaryotic cells?

• cell membrane, chloroplasts, and DNA

• cell membrane, chromosomes, and vacuole

• cell wall, cytoplasm, and DNA

• cell wall, endoplasmic reticulum, and nuclear membrane

Examine the statements listed in the chart. Which statements are evidence that prokaryotes are less complex than eukaryotes?

• A) 1 and 3

• B) 1 and 5

• C) 1, 2, and 3

• D) 3, 4, and 5

Question for a patient who has kidney failure, lack of motor coordination, and a poorly functioning nervous system. After testing, the doctor finds that these symptoms are all related to a chronic lack of energy in some of the patient's cells. The doctor diagnoses a metabolic disorder known as Leigh's disease. Based on this evidence, a malfunction in what organelle is most likely responsible for Leigh's disease?

• A) Golgi Apparatus

• B) mitochondria

• C) nucleus

• D) ribosomes

The post office functions to process, package, and distribute. Which cell organelle has a similar function?

• A) chloroplast

• B) Golgi apparatus

• C) mitochondrion

• D) plasma membrane

Which structure controls what enters or leaves the cell?

• A) cell wall

• B) mitochondrion

• C) plasma membrane

• D) vacuole

Which structures distinguish plant cells from animal cells?

• A) ribosomes and vacuoles

• B) vacuoles and mitochondria

• C) chloroplasts and cell membranes

• D) chloroplasts and cell walls

A student observes a cell through a light microscope and correctly decides that it is a plant cell. What observation would lead to that conclusion?

• Ribosomes are visible.

• A cell membrane is present.

• It has a large, central vacuole.

• The nucleus is in the center of the cell.
