Review Game- Cell Organelles

Which of these correctly identifies a cell organelle and its function?

a.The nucleus temporarily stores materials.

b.The ribosome makes proteins. c.The vacuole performs cellular

respiration. d.The Golgi complex converts light

energy into chemical energy.

Look at this diagram of an animal cell.

The arrow is pointing to a.the endoplasmic reticulum b.the Golgi apparatus c.a mitochondrion d.a ribosome

Which best describes the function of a lysosome?

A manufacturing proteinsB protecting the cell C controlling cell activitiesD storing waste products

In the plant cell, which organelle uses light energy to make food for the plant?

A mitochondria B ribosomes

C vacuoleD chloroplast

Which organelle is responsible for controlling the diffusion of nutrients in and out of the cell?

A vacuoleB mitochondriaC cell membraneD nucleolus

Levels of Organization

A group of cells that work together is a(n):

A organismB tissueC organ systemD organ

Which of the following is the smallest level of organization in the integumentary system?

A bone tissue B toenailC skin cell D hair

Mitosis

Which of the following does not happen during Interphase:

A)The cell prepares itself to divide into two new cells. B)The cell grows to its full size. C)The cell deletes the parts it doesn’t need anymore. D)The cell makes an exact copy of its DNA

During which phase of cell division do the chromosomes line up in the center of the cell?

A metaphaseB cytokinesisC anaphaseD interphase

During this phase of mitosis, new chromosomes stretch out, a new nucleus forms around each set of chromosomes, and a new cell membrane begins to form:

A Prophase B Metaphase C Anaphase D Telophase

Photosynthesis and Respiration

Which of these equations shows the reactants and products of photosynthesis?

A sugar + carbon dioxide oxygen +

waterB water + oxygen sugar + carbon dioxide C sugar + oxygen carbon dioxide + water D carbon dioxide + water sugar + oxygen

During respiration, glucose (C6H12O6) and oxygen (O2) react together and they produce:

A oxygen (O2) and carbon (C). B glucose (C6H12O6) and methane (CH4).C carbon dioxide (CO2) and water (H2O). D hydrogen (H2) and oxygen (O2).

In which organelle does respiration happen?

A mitochondriaB chloroplastC vacuoleD cell membrane

Which statement best explains how photosynthesis and cellular respiration are related to one another?

a.Plant cells are the only cells that perform either photosynthesis or cellular respiration.

b.Glucose is a product of both photosynthesis and cellular respiration.

c.Water is a reactant of both photosynthesis and cellular respiration.

d.Products in photosynthesis are reactants in cellular respiration.

Diffusion

Students placed a raw egg without its shell into a highly concentrated solution of sugar. If the amount of sugar in the solution is greater than in the egg, which of these is most likely to occur?

A Water will flow into the egg and cause the egg to expand.

B Water will flow out of the egg and cause the egg to shrink.

C The sugar will dissolve the egg. D The sugar will break the egg into

pieces.

The diagram below shows a process that occurs in living organisms.

Which process is most likely represented in this diagram?

a.sexual reproduction b.cellular respiration c.simple diffusion d.cell division

Most single-celled aquatic organisms use oxygen that is dissolved in water. When the dissolved oxygen concentration in the water is greater than the oxygen concentration in the organism, oxygen molecules pass through the cell membrane into the organism. What process causes this movement of oxygen molecules?

a.respiration b.photosynthesis

c.mitosis d.diffusion

After a living cell is placed in pure water, the cell will

a.enlarge when water diffuses across the membrane into the cytoplasm.

b.shrink when large molecules are transported into the cytoplasm.

c.enlarge when water from inside the cell is carried out across the membrane.

d.shrink when sugars diffuse out of the cell across the membrane.

A student put a stalk of wilted celery into a glass of water. After one hour, the celery was no longer wilted.

Which sentence best explains why the celery stalk was no longer wilted?

a.Salt diffused out of the cells of the celery stalk.

b.Salt diffused into the cells of the celery stalk.

c.Water diffused out of the cells of the celery stalk.

d.Water diffused into the cells of the celery stalk.

Heredity In one type of plant, red flowers (R) are

dominant to white flowers (r). Two plants that are heterozygous for red flowers are crossed.

What is the probability that this cross will produce an offspring with white flowers?

a.1/4 b.2/4c.3/4 d.4/4

The table below shows four traits that occur in guinea pigs.

Two parent guinea pigs that both express recessive traits are crossed. Which trait will most likely be expressed in the offspring?

a.rough coat texture b.short fur c.black coat color d.white spots
