Answer 14

Autotrophs

Question 15

What is the process by which autotrophs convert CO2 and H2O into carbohydrates?

Answer 15

Photosynthesis

Question 16

Fill in the blank: The process of photosynthesis occurs in the presence of _______.

Answer 16

chlorophyll and sunlight

Question 17

What is the process by which green plants prepare food called?

Answer 17

Photosynthesis

Photosynthesis is essential for plant growth and energy production.

Question 18

What type of energy is converted into chemical energy during photosynthesis?

Answer 18

Solar energy

Solar energy is harnessed from sunlight.

Question 19

What are formed during the process of photosynthesis?

Answer 19

Carbohydrates

Carbohydrates serve as energy sources for plants.

Question 20

Where is the main site of photosynthesis in plants?

Answer 20

Green leaves

Green leaves contain the necessary pigments for this process.

Question 21

What pigment is found in the green portion of the plant that is crucial for photosynthesis?

Answer 21

Chlorophyll

Chlorophyll is the green pigment that captures light energy.

Question 22

What is the chemical equation that represents photosynthesis?

Answer 22

6CO + 12H2O gives C6H12O6 + 6H2O

This equation illustrates the conversion of carbon dioxide and water into glucose and oxygen.

Question 23

What are the raw materials for photosynthesis?

Answer 23

Sunlight, Chlorophyll, CO2, Water

These materials are essential for the process of photosynthesis in plants.

Question 24

What role does chlorophyll play in photosynthesis?

Answer 24

It absorbs sunlight in the chloroplast

Chlorophyll is a pigment that captures light energy for photosynthesis.

Question 25

How does carbon dioxide enter the plant?

Answer 25

Through stomata on the leaves ## Footnote Stomata are small openings that regulate gas exchange.

Question 26

What is released as a byproduct of photosynthesis?

Answer 26

Oxygen (O2) ## Footnote Oxygen is released through stomata during the process.

Question 27

Where does water come from for photosynthesis?

Answer 27

From the soil, taken up by roots ## Footnote Water is absorbed along with dissolved minerals necessary for plant growth.

Question 28

What is the function of xylem tissue in plants?

Answer 28

To transport water from roots to stems ## Footnote Xylem is a type of vascular tissue responsible for water conduction.

Question 29

Fill in the blank: Water and dissolved minerals are taken up by the roots from the _______.

Answer 29

soil ## Footnote This process is vital for providing essential nutrients to the plant.

Question 30

True or False: Only sunlight is needed for photosynthesis.

Answer 30

False ## Footnote Photosynthesis requires sunlight, carbon dioxide, and water.
