31

What is the second highest layers of a leave called

Palisade Layer

32

What is the 2nd lowest layer of a leave called

Spongy Layer

33

What is the lowest layer of a leave called

Lower Epidermis

34

What are Chloroplasts

These are tiny sacs filled with stomata

35

What occurs in the stroma of the chloroplast

The reactions that result In the creation of starches (sugar) occur in the stroma of the chloroplast. These reactions utilize a solution of enzymes useful for photosynthesis

36

How is the outer membrane of a chloroplast like

The outer membrane of the chloroplast is smooth and allows some molecules to pass through freely

37

How is the inner membrane of a chloroplast like

The inner membrane has proteins that regulate the passage of protein, sugars, and other small molecules into and out of the chloroplast

38

Why is a leaf green

Plants have 2 kinds of chlorophyll. When light shines on a plant, the chlorophyll molecules absorb wavelengths in the red and blue range. The only light not absorbed by either type of chlorophyll is green

39

What molecule created during photosynthesis is stored by the plant as energy for later use

Glucose

40

What does carbon dioxide have to do with photosynthesis

It comes from the air and is used to make glucose

41

What does water have to do with photosynthesis

It comes from the ground and is used to make glucose

42

What does glucose have to do with photosynthesis

It is formed during the process of photosynthesis

43

What does sunlight have to do with photosynthesis

Energy from the sun is stored in bonds of glucose

44

What are the key compounds of photosynthesis

Carbon dioxide, Water, Glucose, and Sunlight

45

Where does photosynthesis occur

In the chloroplast

46

How is energy converted during photosynthesis

Energy from the sun is stored in bonds of glucose

47

Cellular Respiration Definition

The process of breaking down glucose for the production of ATP

48

Palisade Layer Definition

The layer of columnar cells usually present in the upper side of the mesophyll of a leaf

49

Sponge Layer Definition

The layer of netlike cells usually present in the lower side of the mesophyll of a leaf

50

Stomata Definition

(stoma: sing.) the openings in leaves through which gas flows

51

Mesophyll Definition

The internal ground tissue located between the two epidermal cell layers of the leaf; and is composed of two kinds of tissues: the palisade parenchyma, an upper layer of elongated chlorenchyma cells containing large amounts of chloroplasts; and the spongy parenchyma, a lower layer of spherical or ovoid

52

Any cell in an organism perform how many chemical reactions

Thousands of chemical reactions

53

What do some reactions in cells do

Some break down molecules and others build up molecules

54

Why do cells need to break down molecules

To get energy to perform the functions of the cell

55

Is glucose broken down in one reaction

Glucose isn’t broken down in one reaction but is broken down in a series of reactions. Some of these reactions depend on the presence on the presence of oxygen. The net result of these reactions is the conversion of ADP to ATP

56

What is the fist step of breaking down glucose

In the first stage, molecules such as glucose are split in a process called glycolysis. This produces a small amount of ATP

57

If oxygen is present what happens in the break down of glucose

A series of aerobic reactions take place to make ATP. These reactions describe cellular respiration

58

If oxygen isn’t present what happened in the break down of glucose

In the absence of oxygen, a series of anaerobic reactions describing fermentation takes place

59

Where does glycolysis take place

Glycolysis takes place in the cytoplasm

60

What does the word glycolysis mean

“To split the sugar”
