As a species I am not to blame if I edge out native species and decrease your biodiversity. You have tagged me as an _________ species
INVASIVE
Usually “imported” by humans, tend to “push” out native species

20. Not all producers are plants that’s why we prefer the term:
AUTOTROPH
Algae, phytoplankton
Use photosynthesis and chemosynthesis to produce food

21. ONLY in plants site of photosynthesis = production of glucose
I capture the sun’s radiant energy and transform it into chemical energy.
CHOLORPLAST
ONLY in plants site of photosynthesis = production of glucose

22. I am a genius and in command of my SMALL world
NUCLEUS
Location of DNA/Chromosomes – contains all information about how an organism is built and functions

23. SEXUAL Greater diversity of within species and populations 2 parents
By using this method of reproduction we guarantee a greater mix of genetic material and a greater biodiversity.
SEXUAL
Greater diversity of within species and populations
2 parents

24. All ecosystems want to continue indefinitely so we do all we can to maintain our:
SUSTAINABILITY
Ability to maintain and continue
Species able to survive indefinately

25. Our offspring are not uniform they are very…..
DIVERSE
Sexual reproduction, 2 parents, combination of different genetic material increases the gene pool

26. PHOTOSYNTHESIS Takes place in chloroplasts of autotrophs
I am the process that takes in sunlight, water, and carbon dioxide to produce glucose and oxygen.
PHOTOSYNTHESIS
Takes place in chloroplasts of autotrophs

27. Plant cells like by rigidity because I provide them with structure and support
CELL WALL
ONLY in plants, made of cellulose – cell membrane will pull away from cell wall when turgor pressure is lost

28. WORK Unit of measurement = joule (j)
Accomplishment means you have applied a force and moved an object some distance. I am calculated by multiplying: F x D
WORK
Unit of measurement = joule (j)

29. Helps maintain homeostasis by helping to control body temperature
My largest organ is the skin and I act as a barrier to protect the body. I am the __________ system.
INTEGUMENTARY
Helps maintain homeostasis by helping to control body temperature

30. Although I am part of the digestive system no digestion takes place, only absorption of water and dissolved nutrients.
LARGE INTESTINES
NO DIGESTION. E. coli live here and “feed” on undigested materials producing vitamin K which we need = symbiosis / Mutualism

31. Nothing can SUCK because I am defined as a push or a pull
FORCE
F = m x a
Unit of measurement = newton (N)

32. DNA Makes up our Chromosomes holds our genetic code
I store all the data that codes for who you are and how you work. I am located in the nucleus.

Makes up our Chromosomes holds our genetic code

33. I am a special key that can not open any locks but I can help you identify an organism.

EXCRETORY
Removes liquid waste from the body – filtered and collected in the kidney > passes thru ureters to the urinary bladder then out of body thru the urethra

40. I am a genius and in command of my SMALL world
NUCLEUS

41. Omnivore, Carnivore, Herbivore we are all a type of…..
HETEROTROPH
Cannot make our own food we need to COMSUME other organisms to get food

42. Please keep me watered properly so that my vacuoles will stay full and maintain __________ pressure so I do not wilt.
TURGOR
Cell membrane will pull away from cell wall, cell will appear to “shrink” when turgor pressure is lost. Plants will wilt and eventually die if they do not receive adequate amounts of water
