STAAR REVIEW-B.4(A-B)-Cellulary Comlpexity

Both Euglena and Cyanobacteria are photosynthetic, unicellular organisms that live in pond water. The feature that distinguises the Euglena from the bacteria is-

• The ability to maintain homeostasis

• The presence of ribosomes

• The ability to reproduce

• A nucleus surrounded by a nuclear membrane

Which of these statement best explains the energy conversion that takes place in the mitochondria?

• Energy is required to convert carbon dioxide into glucose molecules

• Water molecules and sunlight are used for anaerobic respiration

• Oxygen molecules are released in the form of heat

• The energy in glucose molecules is converted to ATP energy

Students used vinegar to dissolve away the shells of the eggs to model red blood cells. Then they obseved the changes of the eggs when placed in different solutions.

Which statement best describes the role of the cell membrane in this model?

• The cell membrane is an impermeable barrier that prevents water from entering the cell

• The cell membrane allows solutes to enter the cell causing it to shrink

• The cell membrane allows water to enter and leave the cell by osmosis

• The cell membrane removes solutes from the environment

Cells can generate as much as 36 to 38 molecules of ATP from one molecule of glucose. Which cellular process results in this ATP production?

• Anaerobic cellular respiration

• Protein Synthesis

• Aerobic cellular respiration

• Photosynthesis

The diagram shows cellular activity across a cell membrane.

Which two processes does this diagram directly model?

• Energy conversion and synthesis of new molecules

• Synthesis of new molecules and homeostasis

• Transport of molecules and energy conversion

• Transport of molecules and homeostasis

Students use a microscope to look for structures present in four different cells. The students placed an 'X' for each structure they saw in each cell.

Which cell that was viewed was most likely a prokaryote?

• Cell W

• Cell X

• Cell Y

• Cell Z

A type of cellular transport is shown. Which description best identifies this type of cell transport?

• Active Transport, because energy is being used to move molecules against the concentration gradient

• Facilitated Diffusion, because energy is being used to move molecules with the concentration gradient

• Osmosis, because no energy is being used to transport water with the concentration gradient

• Endocytosis, because no energy is being used to move molecules against the concentration gradient

Which cellular process takes place in the ribosome attached to the endoplasmic reticulum?

• The breakdown of waste materials

• The conversion of radiant energy to glucose

• The synthesis of new proteins

• The replication of nucleic acids

Examine the image. Which statement best describes the flow of energy.

• Light energy is converted to ATP in the chloroplast.

• Glucose and Oxygen are produced in the chloroplast and then used as reactants in the mitochondria.

• Cellular Respiration and Photosynthesis have no relationship.

• Water and Carbon Dioxide are used to produce radiant energy in the chloroplast.
