The cuticle and upper epidermis provide protection for the plant. Below that is the palisade layer<span>, which is the location of photosynthesis within the leaf. Below the </span>palisade layer<span> is the spongy </span>layer<span>, which contains cells that are more spread out, allowing for air pockets.</span>

pentagon [3]

Answer:

The paragraph illustrated in the question reminds me the first law of thermodynamics.

Explanation:

According to the first law of thermodynamics or law of energy conservation theory states that the total amount of energy of the universe always remains constant.Energy can neither be synthesized nor destroyed.Energy can only be transformed.

   Both photosynthesis and cellular respiration obey the law of energy conservation or the first law of thermodynamics.Because during photosynthesis the light energy is converted to chemical energy that is stored in the chemical bonds present in glucose.

  Whereas during cellular respiration the glucose is broken down  by oxidation to release free energy in form of ATP.

How could the botanist best determine whether the genotype of the green-pod plant is homozygous or heterozygous?
murzikaleks [220]

Answer:

C

Explanation:

Homozygosity is when the two alleles (gene form) are the same while heterozygosity is when the alleles are of different types.

In a gene, an allele is capable of masking the expression of another. The allele being expressed or that masks is called the DOMINANT allele while the allele being masked is the RECESSIVE allele.

A recessive allele will only be expressed (phenotypically) if the two alleles are of the same type i.e. homologous but when a dominant phenotype is expressed, one cannot ascertain whether the organism is heterozygous or homozygous for that gene. e.g T is the gene coding for height in plant, T which represents tallness is dominant over t, representing shortness. In a heterozygous (Tt) and homozygous dominant (TT) state, the plant will be phenotypically tall but will only be short in a homozygous recessive (tt) state.

Since the plant will be tall in homozygous (TT) or heterozygous (Tt), we cannot detect the actual genotype of the plant. Hence, a test cross is done.

A test cross is a cross between a dominant phenotype and a homozygous recessive in order to determine the actual genotype of the dominant organism i.e. whether homozygous or heterozygous.

In this case involving pod color gene, since the botanist is trying to determine whether the genotype of the green pod plant is heterozygous or homozygous, it means the allele for green pod is dominant over that of yellow pod (recessive).

N.B: The recessive trait can only be expressed if it is homozygous. Therefore, the yellow pod plant has homozygous recessive genotype.

A test cross is conducted by the botanist to determine whether the green pod plant is heterozygous or homozygous by crossing it with a yellow pod plant (homozygous recessive).

If any of the offspring plants exhibit recessive traits i.e. yellow pods, it means the parent green pod plant is heterozygous but if all the offspring plants show phenotypic dominant traits i.e green pod, it means the parent green pod plant is homozygous.
