Explanation:
Symbiosis is a physical association between two different organisms whereby both benefit from the relationship. A good example is the lichens. These are composite plants consisting of blue-green algae within the mycelial mass of fungus. The algae are provided with a means of attachment. They also obtain water, carbon dioxide and mineral salts from the fungus. The fungus obtains oxygen and carbohydrates made by algae through photosynthesis.

Answer:
A. Tt - Tall or Short or Both
B. tt
- Short Only
C. TT- Tall Only
Explanation:
Given -
Height of plant is controlled by a single gene.
"T" represents tall heighted plant while "t" represents short heighted plant
Considering "t" is a recessive allele and "T" is a dominant allele.
Thus,
a) Tall Only means that both the alleles in the genotype would be "TT"
b) Short Only means that both the alleles in the genotype would be "tt"
c) Tall or Short or Both means that the genotype has one "T" and another "t" allele, represneted by "Tt"
Thus,
A. Tt - Tall or Short or Both
B. tt
- Short Only
C. TT- Tall Only
