While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. ... While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

I think you mean Round could be RR or Rr (round is dominant to wrinkled)
R=round
r=wrinkled
RR would be round phenotypically
Rr would be round phenotypically
To determine if they are RR or Rr you should perform a backcross with a wrinkled mutant!
I put a picture to demonstrate this.
If they are RR then if you cross with rr you would only get phenotypically Round pea plants.
If they are Rr then if you cross with rr you would get 50% round and 50% wrinkled. Any wrinkled? Definitely the heterozygote Rr!!
The lymphatic system destroy harmful substances 'By producing antibodies'.
The lymphocytes contained in lymphatic organs are produced with other defence cells by the bone marrow. They are then dispersed to eliminate pathogens.
