Students are asked to pair a plant structure to its physiological function as well as give evidence for why that structure is important for the process they describe.

• Shantal: The cambium are important for photosynthesis because they allow water into the plant

which is needed as a reactant for photosynthesis.

• Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves

in order to perform cellular respiration.

• Enrique: The guard cells are needed during food production because they regulate how much water

the plant retains or loses during glycolysis.

• Anne: The seeds of the plant are needed for reproductive purposes and they can be dispersed or

spread out over a large area.

Which student correctly described a plant structure, its physiological function, and gave appropriate

evidence?

O Shantal

O Jamil

O Enrique

O Anne

Anne

Explanation:

The only student that correctly described a plant structure, its physiological functions, and gave appropriate evidence is Anne.

The seeds of plants are propagules and, depending on the kind of seed, can be dispersed over a large area from their parent plants.

The phloem of a plant is primarily concerned with the conduction of synthesized food around the body of the plant from the source of production. Hence, Jamil's description that the phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves was inaccurate.

The guard cells control the rate of evapotranspiration of water from the plant but have nothing to do with the breakdown of glucose, also known as glycolysis. Thus, Enrique's assertion was also inaccurate.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
