This question has three parts.

Corn plants produce their own food through a chemical process.

1

Drag and drop a molecule into each box in the equation to show the chemical reaction corn plants use to make food. Each chemical symbol may be used once or not at all.

Identify the source that provides energy for the chemical reaction in number 1 to occur.

1

Describe how human cells use the products from the chemical reaction in Number 1. Be sure to include the process that occurs at the cellular level.

Scientists crossed true-breeding corn and true-breeding teosinte to determine whether the plants produce fertile offspring. Which of the following questions was this experiment designed to answer?

Are corn and teosinte different species?

Do corn and teosinte both use seeds to reproduce?

Can corn and teosinte plants grow in similar environments?

Do corn plants contain more dominant alleles than teosinte plants do?

1

A student claims that the inheritance pattern for kernel coating is incomplete dominance.
Which of the following pieces of evidence best supports the student’s claim?

Corn and teosinte share the scientific name Zea mays.

Early farmers produced corn by selectively breeding teosinte.

A single gene with two alleles codes for the presence or absence of kernel coating in Zea mays.

The cross between domestic corn and teosinte produced offspring with partially formed kernel coatings.

Scientists studied reproduction in corn and teosinte.
Select two types of cells that combine to produce offspring when a corn plant is crossed with a teosinte plant.

1

Corn kernels are fertilized seeds that develop into corn plants after they are planted. How does the number of chromosomes in a corn kernel cell compare to the number of chromosomes in the body cell of a corn plant?

A corn kernel cell has half as many chromosomes as the body cell because the kernel is a gamete.

A corn kernel cell has the same number of chromosomes as the body cell because the kernel developed from a zygote.

A corn kernel cell has twice as many chromosomes as the body cell because the kernel developed from two corn plants.

A corn kernel cell has no chromosomes and the body cell has a full set of chromosomes because chromosomes are produced as the corn plant grows.
