33. Comparing Cell Parts- Part of a cell and tell me what it's made of and it is a true false question.

34. Evolution of cells

Cell theory states that all living things are composed of cells and that all cells come from earlier cells. So every cell in your body (and in every other living organism on Earth) was formed by division of a previously living cell.

35. Size of cells

Students might wrongly conclude that prokaryotes are typically one-tenth the volume of eukaryotic cells. A difference in diameter by a factor of ten translates into a much greater difference in volume. Students might be challenged to recall enough geometr

36. Compare plant and animal cells

Organisms are either single-celled, such as most prokaryotes and protists, or multicelled, such as plants, animals, and most fungi. In animals, carbohydrates are a primary source of dietary energy and raw material for manufacturing other kinds of organic

37. Cell membrane

The plasma membrane separates the living cell from its nonliving surroundings.

38. DNA, Forms of DNA

2. Noting the main flow of genetic information from DNA to RNA to protein on the board will provide a useful reference for students when explaining these processes. As a review, have students note where new molecules of DNA, RNA, and proteins are produced

39. Something about ER

The endomembrane system in a cell consists of the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, and vacuoles. The endoplasmic reticulum is continuous with the outer nuclear membrane. This explains why the ER is usually found

40. Something about the Golgi

The Golgi apparatus works in partnership with the ER and receives, refines, stores, and distributes chemical products of the cell.

41. Compare two organelles

Students might have trouble connecting the diverse functions to the organelles. The pathway of secretory proteins is a good process to use to introduce the primary organelle functions. The movement of information and products extends generally from the ce

42. Unique Cellular structure, locomotor organelle

Cilia (singular, cilium) are generally shorter and more numerous than flagella and move in a coordinated back-and-forth motion, like the rhythmic oars of a crew team. Both cilia and flagella propel various protist through water.

43. Locomotor organelles

Eukaryotic flagella propel cells through an undulating, whiplike motion. They often occur singly, such as in human sperm cells, but may also appear in groups on the outer surface of protists.

44. Compare chloroplasts and mitochondria

Mitochondria are found in almost all eukaryotic cells, are the organelles in which cellular respiration takes place, and produce ATP from the energy of food molecules. Cells use molecules of ATP as the direct energy source for most of their work. Chloropl

45. Similarities of the mitochondria and chloroplasts

Students frequently equate the functions of mitochondria and chloroplasts as alternative ways to acquire usable energy. This often leads to the conclusion that animal cells have mitochondria but not chloroplasts and that plant cells have chloroplasts but

46. Two kinds of energy, tell him if it's one kind of energy.

Example given Kinetic energy is the energy of motion. Potential energy is stored energy, energy that an object has because of its location or structure.

47. Compare Calories versus killer calories

A calorie (cal) is the amount of energy that can raise the temperature of 1 gram (g) of water by 1�C. Food Calories are kilocalories, equal to 1,000 calories. The energy of calories in food is used to fuel the activities of life.

48. Enzymes

Enzymes within the cell carry out a process called glycolysis. During glycolysis, the energy released from the breakdown of glucose is used to produce molecules of ATP. Within a living sperm, the ATP produced during glycolysis and other processes provides

49. Solutions

a hypertonic solution has a higher concentration of solute, a hypotonic solution has a lower concentration of solute, and an isotonic solution has an equal concentration of solute.

50. Enzymes

To harness this energy-producing system, researchers attached three glycolysis enzymes to a computer chip. The enzymes continued to function in this artificial system, producing energy from sugar. The hope is that a larger set of enzymes can eventually be
