I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:
You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled
If you are crossing rr with an Rr (so a heterozygote wrinkled):
50% will be Rr (wrinkled)
50% will be rr (round)
See my picture for the Punnett Squares for both answers!
Answer:Because plasma membrane structure contain Llipids and protein.
Explanation:
Lipid make it differential permiable while protein make it selectively permiable , Protein act as carrier (permiase) Also Act as receptor and provide receptor site , control the concentration of substance and many other function.
Both organelles are round, and membrane-bound. They also have internal sacs that form a lumen that is the site for synthesis and transport of respective products. For thylakoid, they are the site for synthesis of photosynthesis while Golgi is sited for lipids and protein synthesis
4) Oxygen and Glucose are the reactants for cellular respiration.
