Cells/Organelles Exam

Rotenone is an insecticide that is toxic to humans as well as to insects. Rotenone interferes with the process of ATP production in the cell. Which would correctly identify the structure where ATP is produced and is affected by rotenone

2: Production of ATP would occurs less efficiently

Which structure is best observed using a compound light microscope

A cell

Which structure are found in every living cell?

A plasma membrane and cytoplasm

What is commons to all cells

All cells divide to form new cells

Some viruses attack cells by attaching to their outer covering, entering, and taking over their genetic "machinery." Viruses are able to invade cells after first attaching to their

Cell membrane

The respiratory system of an elephant functions in a similar way to which organelle in a single celled organism

Cell membrane

A cylindrical structure that appears to function in the division of certain cells is the

Centriole

Microscope examination of an animal cell reveals the presence of a plasma membrane but no cell wall. Which additional structures would normally be present within this cells?

Centrioles

Studies of fat cells and thyroid cells show that fat cells have fewer mitochondria than thyroid cells. A biologist would most likely infer that fat tissue

It requires less energy than thyroid tissue

Metabolic processes

Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the?

Mitochondria

While viewing a slide of rapidly moving sperm cells, a student concludes that these cells require a large amount of energy to maintain their activity. What organelles provide this needed energy?

Mitochondria

In which cells structure is energy extracted from nutrients?

Mitochondrion

Which cell structure is mainly responsible for releasing energy from food molecules in single celled organisms

Mitochondrion

An ameba a one celled organism can move ingest and transport materials within the cell because it has

Organelles

A brick is to a house as a cell it to an...

Organism

Certain poisons are toxic to organisms because they interfere with the function of enzymes in mitochondria. This results directly in the inability of the cell to

Release energy from nutrients

aerobic respiration

Respiration that requires oxygen

What is the site of protein synthesis in plant cells?

Ribosomes

An ameba is a single celled organism. It uses its cell membrane to obtain food from its environment, digests the food with the help of organelles called lysosomes, and uses other organelle to process the digested food. From this, we can best infer that

Structures in amebas have functions similar to organs in multicellular organisms

The cellular structure must oxygen cross to get from the outside to the inside of an animal cell

The plasma membrane

In single celled organism,materials are stored primarily in

Vacuoles

During an experiment you want to view the nucleus of a cell. How would you most easily view this organelle?

With a microscope

Which cell organelle is composed of a series of channels throughout the cytoplasm that functions in the transport of molecules?

endoplasmic reticulum

Which cell structure is correctly paired with its primary function

ribosome - protein synthesis
