Big Idea 2

21. Adhesion of water- The joining of water to another substance. 
In this aquarium the water molecules have joined with those of the viewing glass, creating adhesion.

22. ATP- Transports chemical energy within cells to provide cells with energy.  This Tufted Capuchin is eating, then his body will turn the food into glucose and through glycolysis, krebs cycle, and the electron transport chain it’s body will turn it into ATP.

23. Autotroph- an organism that can form substances from simple substances like water.  This Christmas tree uses photosynthesis to produce oxygen and glucose.

24. Carbohydrate- a substance that contains hydrogen and oxygen in a 2:1 ratio.  Sugar is made of chains of glucose, which is a six carbon sugar.

25. Cellulose- a polysaccharide consisting of chains of glucose monomers.  This lilly cell walls are made from cellulose.

26. Chitin- a substance consisting of polysaccharides that forms the cell walls of fungi.  This is an imprint of the seeds of an heirloom mushroom, which is a fungi.

27. Cohesion of water- when water molecules stick to one another.  The water in this aquarium  is connected together by hydrogen bonds.

28. Ectothermy- an organism that regulates its body temperature by exchanging heat with its surroundings.  This Blood Python like all reptiles is “cold blooded” meaning that its temperature is regulated by it’s environment.

29. Enzyme- acts as a catalyst to bring down the activation energy required for a reaction. Fish use enzymes when they eat their food.

30. Fermentation- the chemic al breakdown of microorganisms.  This grappa was made through alcohol fermentation.

31. Hypertonic- something that has a greater amount of particles than something else. The teabag has a greater amount of particles than the water.

32. Hydrophilic- a substance that mixes with water.  The balsamic vinegar has mixed with the water and didn’t create two separate layers like water and oil does.

33. Isotonic- a substance that has the same osmotic pressure as another substance. This tap water has the same amount of particles as itself.

34. Kinesis- the movement of an organism in response to a stimulus.  This Masai Giraffe has moved to the food.

35. Phloem- the tissue in plants that transports metabolic products from the leaves. The bottom of this arugula shows the phloem of the plant.

36. Stomata- the pores in the epidermis of the leaf of the plant, that allows gases into the plant. The bottom of this leaf is where the stomata are located on this Chinese evergreen.

37. Unsaturated fat- a fat with at least one double bonded carbon, which makes that fat kink and unable to stack making them non solids at room temperature.

38. Xylem- the tissue in a plant that carries water and nutrients from the roots to the rest of the plant. The roots of the celery is how the pant gets water from the ground.

39. Glycolysis- the breakdown of glucose, which releases energy.  This Guanaco must breakdown glucose to produce ATP so it can move.

40. Lactic Acid- a product of strenuous exercise that builds up in the muscles. My cat builds up lactic acid when she jumps and runs around the house.
