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
In a cell, all organelle work together to carry out...
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
