Answer:
Answer is D.Produce non-identical genetically different gametes and reduction of chromosomes,creating a haploid gamete.
Explanation:
Meiosis is essential for sexual reproduction.In humans diploid gamete-mother cells or germ line undergo meiosis to produce haploid gametes.
The chromosomes pairs of each parent undergo crossing over during meiosis.so daughter cells i.e gametes have genetic variations.When gametes fuse and form zygote ,its genetic make up is different from both parents.thus meiosis allows a species to bring variations in next generations.Benenficial variations help organisms to adapt to the changes in environment.
Answer:
A. If neither parent expresses the trait, but the offspring does, both parents must be heterozygous for the trait.
Explanation:
If neither parents express the trait is because they are heterozygous and the dominant allele is being expressed over the recessive trait. When parents cross they have 25% of having an offspring that expresses the recessive trait, this means the offspring is a recessive homozygous. In the attached example 25% or 1/4 will have a short stem.

Answer:
Cell wall: A protective layer covering the outside of the cell. They keep the shape of the plant cell, prevent water loss, and provide support.
golgi apparatus: Transports proteins and lipids around the cell. Often it is called the shipping department of the cell.
chloroplast: Chloroplasts store chlorophyll and this is where photosynthesis takes place in the cell.
Cell membrane: A layer that covers the cell, acts as a gate and determines what comes and goes through the cell. It allows good things in, while keeping others out.
Intermediate filaments: Provides support when when the plant cell comes into contact with other cells.
Ribosome: The part of the cell that is responsible for creating proteins.
