Answer:
It means that the cell membrane allows certain substances to pass through and not others. As the cell membrane consists of a phospholipid bilayer with a hydrophobic core, only small uncharged hydrophobic molecules can pass through the cell membrane e.g. glucocorticoid and other larger charged particles require transporters or channel proteins to pass through the cell membrane, e.g. glucose.

Answer:
One offspring would have red leaves.
Explanation:
Given
Yellow leaves are dominant and red leaves are recessive
Let us assume that the trait of Yellow color of a leaf be represented by "Y"
and the trait of red color of a leaf be represented by "y"
When two parent of genotype "Yy" are crossed with each other, the following offsprings are produced as shown in the punnet square below
Y y
Y YY Yy
y Yy yy
Total four offpsrings are produced out of which only one has red leave as red color is a recessive trait and it will appear only when both the allele in a cell are of red color.
Thus, one offspring would have red leaves.
