TCAP Cell Practice

Students look at pictures of structures found in living organisms. Each picture represents a different level of complexity. Which sequence places the structures in order from least complex to most complex?

• 1-> 2-> 4-> 3

• 1-> 3-> 2 -> 4

• 2->1 -> 3 -> 4

• 2 -> 1 -> 4 -> 3

Protists are organisms that are classified in their own kingdom. Protists are not plants or animals, yet some protists have characteristics similar to those of either plants or animals or both. A protist like the protozoan shown in the picture has similarities to both plants and animals. This protozoan is similar to animals because it has the ability to move from place to place while obtaining nutrients. This protozoan also shares a similarity with plants. Which feature labeled on the protozoan is associated with organisms in the plant kingdom but not in other kingdoms except protists?

• mitochondrion

• chloroplast

• flagellum

• nucleus

A student investigates the process of passive transport by the cell membrane by creating a model. The student puts a starch solution in a dialysis tubing bag. The bag is then placed in a beaker that contains an iodine solution. The dialysis tubing bag is semipermeable. The student’s observations are in the table. The student concludes that the iodine passes through the dialysis tubing material but the starch molecules cannot.

Which two statements provide evidence to support the student’s

conclusion?

• The starch solution turned blue-black after the bag was placed in the beaker.

• The iodine solution did not change color after the bag was placed in the

  beaker.

• The iodine molecules passed through the bag because they are not the same size as the starch molecules.

• The starch solution did not react with the iodine solution after the bag was

  placed in the beaker.

• The change in color of the iodine solution was due to a student error in procedure.

The diagram represents a cellular process used by cells. In which situation would this process be beneficial to the cells?

• growth and repair, because it produces identical types of cells

• growth and repair, because it makes the cells of the organism larger

• reproduction, because it creates more energy for the organism

• reproduction, because it increases the number of chromosomes in the cells

Which of these statements best explains why the eggs that were soaked

in sugar-water and saltwater solutions both decreased in mass?

• Because these eggs were placed in solutions that had higher concentrations of

  dissolved materials than were inside the eggs, water diffused from inside the

  egg into the liquid.

• Because these eggs were placed in solutions that had lower concentrations of

  dissolved materials than were inside the eggs, water diffused from inside the

  egg into the liquid.

• Because these eggs were placed in solutions that had higher concentrations of

  dissolved materials than were inside the eggs, water diffused from the liquid

  into the egg.

• Because these eggs were placed in solutions that had lower concentrations of

  dissolved materials than were inside the eggs, water diffused from the liquid

  into the egg.

A person riding a bicycle wants to move the bicycle forward. She moves her legs up and down on the bicycle’s pedals. Then the rider wants to stop the bicycle. She stops pedaling and the bicycle slows. She takes one of her feet off a pedal and puts her foot on the ground to stop the bicycle and stay upright.

Which of these best identifies a pathway of systems in the rider’s body, as described in this scenario?

• nervous system ->Musculoskeletal system->circulatory system -> nervous system

• nervous system ->Musculoskeletal system->nervous system ->Musculoskeletal system

• Musculoskeletal system -> nervous system -> circulatory system -> Musculoskeletal system

• Musculoskeletal system ->circulatory system -> Musculoskeletal system-> nervous system

A student uses a microscope to observe a single-celled organism that can move. The organism contains a nucleus and many chloroplasts. Based on the observations, the student claims the organism is not a bacterium. Which observation best supports the student’s claim?

• The organism is unicellular.

• The organism is able to move.

• The organism has a nucleus.

• The organism performs photosynthesis.

A scientist used a microscope to observe a prepared sample on a slide. The scientist’s observations are shown. The drawing illustrates which two levels of biological organization?

• cell

• tissue

• organ

• organism

When an athlete began running, both her breathing and heart rates increased.

The athlete’s breathing and heart rates increased as she was running because the athlete needed to

• exhale more oxygen from her lungs.

• decrease the temperature of her skin.

• increase the amount of carbon dioxide in her blood.

• transport more oxygenated blood to her muscles.

Damaged cells can release chemicals known as growth factors. Some of these growth factors can cause nearby cells to divide.

Which pair identifies the process used by the nearby cells to divide and the result of that process?

• Process: meiosis

  Result: new cells that are genetically different from the parent cell, allowing the new cells to carry out their function better than other new cells

• Process: meiosis

  Result: new cells that are genetically the same as the parent cell, allowing the new cells to develop and specialize into different types of cells

• Process: mitosis

  Result: new cells that are genetically identical, allowing them to perform the same functions as the parent cell

• Process: mitosis

  Result: new cells that are genetically different from the parent cell, allowing the new cells to carry out different functions
