water into the red blood cell
plasma membrane
Which cellular organelle is represented by the diagram below?
A - C - D - B
Which is the correct sequence for the stages of mitotic cell division represented by the diagrams below
D
Which letter in the diagram below indicates the structure that is most closely associated with excretion?
diffusion
Which process accomplishes the movement of gases illustrated by the arrows in the diagram below?
The uncontrolled division of certain body cells, which then invade the surrounding tissues and interfere with the normal functioning of the body, is known as
cancer
Which substances may pass through a cell membrane by simple diffusion?
carbon dioxide and water
cell A, only
Base your answer to the following question on In the diagram below, the dark dots indicate small molecules. These molecules are moving out of the cells, as indicated by the arrows. The number of dots inside and outside of the two cells represents the relative concentrations of the molecules inside and outside of the cells. ATP is being used to move the molecules out of the cell by
ingestion
Base your answer to the following question on Which cell activity is illustrated by the diagrams below?
The phrases below describe several events that occur during the process of mitosis. (A) attachment of double-stranded chromosomes to the spindle apparatus (B) formation of single-stranded chromosomes, which are moved to opposite ends of the cell (C) disintegration of the nuclear membrane (D) nuclear membrane formation around each set of chromosomes, forming two nuclei (E) synthesis of a spindle apparatus Which sequence represents the correct order of these events?
C - E - A - B - D
active transport and diffusion
The arrows in the diagrams below represent the direction of movement of a certain type of molecule through the cell membrane of two different cells. The dots represent the relative concentrations of this molecule. Which processes are illustrated in the diagrams?
If the ribosomes of a cell were destroyed, what effect would this most likely have on the cell?
The cell would be unable to synthesize proteins.
a lipid
The diagram below represents a section of a plasma membrane. What does structure X represent?
Centrioles are cell structures involved primarily in
cell division
Which unstained cellular organelles can be seen with a compound light microscope that has a total magnification of 400×?

Which organelles outside the cell nucleus contain genetic material?
chloroplasts and mitochondria
Which is the correct sequence of historical developments leading to our present knowledge of cells?
compound light microscope cell theory electron microscope
. The movement of chloroplasts along the inner surface of the plasma membrane of an elodea cell is known as
cyclosis
Which cell organelle is composed of a series of channels throughout the cytoplasm that functions in the transport of molecules?
endoplasmic reticulum
If an organism reproduces asexually, its offspring will most likely be
genetically identical to the parent
Muscle cells in athletes often have more mitochondria than muscle cells in non-athletes. Based on this observation, it can be inferred that the muscle cells in athletes
have a greater demand for energy than the muscle cells of non-athletes
A structure that performs a specialized function within a cell is known as
an organelle

a plasma membrane and cytoplasm
The chloroplast is to a plant as

The process in which the net movement of molecules is from a region of lower concentration to a region of-higher concentration is known as
active transport
Which process requires cellular energy?
active transport
