13. An organic catalyst and protein






14. Pertaining to a type of gland that releases its secretion through a duct






15. A wall composed of cellulose that is external to the cell membrane in plants; it is primarily involved in support and in the maintenance of proper internal pressure






16. The organelle that provides mechanical support and carries out motility functions for the cell






17. The haploid - sexual stage in the life cycle of plants






18. A process of asexual reproduction in which the offspring develop from an outgrowth of the plant or animal






19. An air sac in the lung; the site of respiratory exchange - involving diffusion of oxygen and carbon dioxide between the air in the alveolus and the blood in the capillaries

28. A process by which the cytoplasm and the organelles of the cell divide; the final stage of mitosis






29. An over secretion of thyroid that leads to high metabolism and exopthalmia goiter






30. The reproductive organ that produces sex cells






31. A gland composed of two parts - anterior and posterior - each with its own secretions; called the "master gland" because its hormones stimulate secretions by other glands






32. The elimination of metabolic waster matter






33. Adenosine diphosphate (ADP) and adenosine triphosphate (ATP) - which are energy storage molecules






34. A structure found between the cerebral hemispheres of vertebrates; secretes melatonin






35. Describes two or more structures that have similar forms - positions and origins despite the differences between their current functions

39. The part of the alimentary canal between the mouth and the esophagus






40. Small - disc-shaped bodies in the blood that play a chief role in coagulation






41. A process by which the cell membrane is invaginated to form a vesicle which contains extracellular medium






42. A process of photosynthesis in which water is split into H+ and OH-; the hydrogen ion is then joined to NADP






43. A specialized structure that controls osmotic pressure by removing water from the cell






44. An opening in the eye whose size is regulated by the iris






45. The intake of food from the environment into the alimentary canal






46. A kingdom of unicellular living organisms that are neither animals nor plants; includes some groups of algae - slime molds and protozoa
