Relays environmental information about condition

13. 3. What are 3 organelles……
Mitochondria – Control Chemical Reactions, site of respiration
Plastids – Contain Chloroplasts; contain chromoplasts (red, yellow, brown pigments)
Vacuoles – store water, dissolve minerals

14. 4. What are 3 func. of nucleus..
