Q

meristems are

A

Undifferentiated and rapidly dividing cells

26
Q

How does water move through a plant

A

Generally under tension

27
Q

The wave nature of light means

A

As Wavelength increases, Frequency decreases

28
Q

The energy in a photon of lige

A

Increases as frequency increases and Decreases as frequency decreases

29
Q

Plants appear green because

A

They dont absorb green light

30
Q

Which of the following is true about light?

A

Light has wave properties, light has particle properties and blue light is shorter wavelenth than red light

31
Q

What does the light reaction do?

A

Splits water into hydrogen and oxygen.

32
Q

What does the dark reaction do

A

uses the enzyme rubisco

33
Q

What does the dark reaction result in?

A

in Carbohydrate production

34
Q

what is a chemical that blocks the light reaction?

A

Atrazine

35
Q

What does Atp production require?

A

Atp enzyme, Aproton (h+), ELCTRON TRANSPORT

36
Q

Which of the following occurs during the light reaction?

A

Splitting of water into hydrogen and oxygen, Production of NADPH reducing power., movement of protons across the membrane

37
Q

Why are C3 and C4 plants called this?

A

The number of carbons in the molecules in which C02 is first fixed

38
Q

Which plants utilize Rubisco during phosynthesis?

what does the dark reaction consume?

A

Nadph and aTP

40
Q

which plants open their stomates only during the dark?

A

CAM Plants

41
Q

C4 plants have higher carbon fixation efficiency than C3 plants because?

They minimize the amount of oxygen near Rubisco

42
Q

What is a typical expample of Cam plants?

A

Succulents such as cacti

43
Q

C3 plants are less efficent at photosynthesis than C4 plants because

A

Rubisco Recognizes 02 as well as C02
