It's really just sugars and other chemicals produced from a plant and are then transported in the <em>phloem tissue</em>. Assimilates are <u>transported</u> in sieve elements, which work closely together with companion cells to achieve translocation.
Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.
Dihybrid cross is a type of cross that occur between two different genes which differ in their traits.
The cross between homozygous dominant and homozygoys recessive traits results in 1:0:0:0 phenotypic ratio. The resulting offspring will have dominant phenotype but will have carriers of recessive phenotype.
