Question

1. the study of functions and the complex chemical processes that allow plants to grow is known as

a. plant taxonomy.
b. plant physiology.
c. plant nutrition.
d. photosynthesis.

1. chlorophyll is important in plants because it

a. creates an atmosphere where it can determine the osmotic pressure.
b. allows the plant to make good xylem tissue.
c. makes it possible for plants to grow.
d. is also known as the chloroplasts.

1. the rate at which photosynthesis is carried out depends on

a. the amount of fertilizer in the water
b. the amount of oxygen in the atmosphere.
c. the amount of respiration carried on during the daylight hours.
d. the light intensity, temperature, and concentration of carbon dioxide.

1. photosynthesis will work best in which temperature range?

a. 50 – 60 degrees fahrenheit
b. 60 – 70 degrees fahrenheit
c. 65 – 80 degrees fahrenheit
d. 85 – 95 degrees fahrenheit

1. respiration

a. uses food for plant energy.
b. stores energy.
c. occurs in cells that contain chlorophyll.
d. uses carbon dioxide.

1. plant nutrition is

a. plant food added to the plant pot.
b. use of basic chemical elements in the plant.
c. chemical processes providing plants with elements for growth.
d. the measurement of acidity (sourness) and alkalinity (sweetness)

Explanation:

Question 1

• Option a: Plant taxonomy is about classifying plants, not their growth processes.
• Option b: Plant physiology studies plant functions and growth - related chemical processes, matching the description.
• Option c: Plant nutrition focuses on nutrient uptake, not all growth - related processes.
• Option d: Photosynthesis is a specific process, not the study of all plant growth - related functions.

• Option a: Chlorophyll has no role in determining osmotic pressure.
• Option b: Chlorophyll is not related to xylem tissue formation.
• Option c: Chlorophyll is essential for photosynthesis, which enables plant growth.
• Option d: Chlorophyll is a pigment in chloroplasts, not the same as chloroplasts.

• Option a: Fertilizer amount in water is not a direct factor for photosynthesis rate.
• Option b: Oxygen amount in the atmosphere does not directly affect photosynthesis rate.
• Option c: Respiration during the day is not a main factor for photosynthesis rate.
• Option d: Light intensity, temperature, and carbon dioxide concentration are key factors affecting photosynthesis rate.

Answer:

b. plant physiology.
