Quarter 2: Lesson 2

Question 1

A process that converts
solar energy into chemical
energy, in the form of
food, and releases oxygen
molecules in the
atmosphere as a
byproduct. It requires
energy in the form of ATP.

Answer 1

PHOTOSYNTHESIS

Question 2

are
openings in plant
leaves that allow a
them to take up
carbon dioxide and
release oxygen and
water vapor.

Answer 2

Stomata

Question 3

is a waxy substance that
covers the leaf and prevents water
loss.

Answer 3

Cuticle

Question 4

covers all the
parts of a plant; shoots,
stems, leaves, and roots

Answer 4

Epidermis

Question 5

represents the
site of photosynthesis in a
plant where light energy
from the sun is converted
into chemical energy and
stored as foods.

Answer 5

Mesophyll

Question 6

Where does Photosynthesis
take place?

Answer 6

chloroplast

Question 7

chloroplast is also known as?

Answer 7

the site of photosynthesis

Question 8

is a green pigment in
autotropic organisms which is generally
essential for capturing solar energy and
converting it into the chemical energy that
fuels the production of glucose, which plants
use for growth and energy storage.

Answer 8

CHLOROPHYLL

Question 9

is the main pigment
involved in the light reactions of
photosynthesis. It captures light
energy and converts it into chemical
energy.

Question 10

is the main pigment
involved in the light reactions of
photosynthesis. It captures light
energy and converts it into chemical
energy.

Answer 10

• Chlorophyll A

Question 11

assists chlorophyll a
by broadening the range of light
wavelengths a plant can use by
transferring absorbed energy to
chlorophyll a.

Answer 11

Chlorophyll B

Question 12

serve as accessory pigments

that absorb light in regions that
chlorophyll cannot, thus expanding the
range of wavelengths that plants can use for
photosynthesis.

Answer 12

Carotenoids

Question 13

are pigments
responsible for red, purple, and
blue colors in plant tissues,
especially in flowers, fruits, and
leaves.

Answer 13

Anthocyanins

Question 14

are essential for absorbing light
from the sun, converting it into chemical energy, and
enables the plant to produce their food while releasing
oxygen into the environment.

Answer 14

plant pigments

Question 15

This process happens in the
thylakoid membrane of the
chloroplast.

• It requires the input of light
  energy and water to produce
  ATP, NADPH, and Oxygen
  (byproduct).

Answer 15

STEP 1: LIGHT-DEPENDENT REACTION

Question 16

• This process of
  photosynthesis happens in
  the stroma of the
  chloroplast.
• It requires Carbon dioxide,
  ATP, and NADPH to produce
  glucose molecule
  (byproduct).

Answer 16

STEP 2: CALVIN CYCLE (LIGHT-INDEPENDENT REACTION)

Question 17

what does it need to create a ATP, NADPH, and Oxygen in light dependent reaction

Answer 17

input of light
energy and water
