Xylem, which transports water, and phloem, which transports sugar.

Front

What is the function of the cell membrane?

Back

Back

3 individuals are carriers of the trait.

Front

What is the primary role of xylem in plants?

Back

Xylem primarily transports water from the roots to the rest of the plant.

Back

Phloem primarily transports sugars produced by photosynthesis throughout the plant.

Front

Back

A recessive trait is one that is expressed only when two copies of the recessive allele are present.

Front

What is the significance of a carrier in genetics?

Back

A carrier is an individual who has one copy of a recessive allele and can pass it on to offspring without showing symptoms of the trait.
