Cells are generally large enough for the unaided eye to see
All cells are produced from existing cells.
Only animals are made up of cells.
The cells of all organisms contain DNA. In cells of which of the following groups is the cellular DNA enclosed in a nucleus?
Bacteria
Eukaryotes
Prokartotes
Viruses
A number of scientists made contributions to cell theory. Which scientist used a light microscope to observe cells in a slice of cork?
Anton van Leeuwenhoek
Matthias Schleiden
Robert Hooke
Theodor Schwann
Lysosomes are organelles that contain enzymes. Which of the following is a function of lysosomes?
Lysosomes build lipids, carbohydrates, and proteins.
Lysosomes package lipids, carbohydrates, and proteins.
Lysosomes break down lipids, carbohydrates, and proteins.
Lysosomes store lipids, carbohydrates, and proteins.
Which of the following structures are present in both plant and animal cells?
cell walls
centrioles
chloroplasts
mitochondria
All cells contain cell membranes. Which of the following describes the composition of cell membranes?
Cell membranes are composed of carbohydrate chains, which allow all materials to enter and leave the cell.
Cell membranes are composed of cellulose, which provide rigidity for the cell.
Cell membranes are composed of cytoplasm, which allows proteins to be excreted by the cell.
Cell membranes are composed of lipid molecules, which provide a flexible structure.
Which organelles allow plants to support heavy structures such as leaves and flowers?
the cell membranes because they regulate what enters and leaves the cells
the chloroplasts because they convert sunlight into chemical energy
the Golgi apparatus because it packages proteins for storage in the cells
the vacuoles because they are filled with fluid, which provide rigidity
The illustration shows a model of the transport of solute particles from outside the cell to inside the cell.
What type of cell transport is modeled?
The model illustrates active transport because energy is required to move the solute particles from an area of lower concentration to an area of higher concentration.
The model illustrates diffusion because solute particles are moving from an area of higher concentration to an area of lower concentration.
The model illustrates facilitated diffusion because protein channels allow solute particles to cross the cell membrane.
The model illustrates osmosis because water molecules are moving from an area of higher concentration to an area of lower concentration.
Multicellular organisms contain organ systems. Which of the following BEST describes the organs in an organ system?
The organs in an organ system are made up of similar cells.
The organs in an organ system are made up of similar tissues.
The organs in an organ system work together to perform a specific function.
The organs in an organ system work together to perform all the functions a multicellular organism needs to maintain homeostasis.
The human digestive system is comprised of specialized cells, tissues, and organs.
Which lists the parts from least complex to most complex?
muscle tissue, muscle cell, stomach
muscle cell, muscle tissue, stomach
stomach, muscle tissue, muscle cell
stomach, muscle cell, muscle tissue
