Question 1

an organism that can produce its own food

Answer 1

Autotrophs

Question 2

Autotrophs is also called as

Answer 2

producers (plants, algae,
cyanobacteria – no chloroplast, only thylakoid
which is not enclosed in a membrane)

Question 3

an organism that eats other plants or animals for energy and nutrients

Answer 3

Heterotrophs

Question 4

Heterotrophs are also called

Answer 4

consumers (humans, animals,
bacteria, fungi)

Question 5

A metabolic process wherein light energy (sunlight) is transformed into chemical energy

Answer 5

Photosynthesis

Question 6

• is a double-membraned (to be sturdier) organelles found in plants and algae
• serves as site for photosynthesis.
• It contains their own DNA to know how to photosynthesize.

Answer 6

Chloroplast

Question 7

Chloroplast contains what pigment

Answer 7

chlorophyll

Question 8

Where is chloroplast found

Answer 8

Found in green tissues of plants.

Question 9

Structure of chloroplast

Answer 9

• Outer Membrane
• Inner Membrane
• Thylakoid
• Granum/Grana
• Stroma
• Lumen

Question 10

Freely permeable to small molecules.

Answer 10

Outer Membrane

Question 11

Highly selective; contains channel and carrier proteins.

Answer 11

Inner Membrane

Question 12

The fluid-filled internal space which contains DNA, enzymes, and other materials inside the chloroplast.

Answer 12

Stroma

Question 13

Membrane-bound flattened disks; the site of light-dependent reactions of photosynthesis.

Answer 13

thylakoid

Question 14

stacks of thylakoids

Answer 14

Granum/Grana

Question 15

They are substances produced by living organisms that have a color resulting from selective absorption.

Answer 15

Pigments

Question 16

Pigments are also known as

Answer 16

Biochromes

Question 17

photosynthetic pigment that produce blue-green color. (Additional facts: The absorbed colors are the ones you don’t see – you see only the colors that come bouncing back to your eyes.)

Answer 17

Chlorophyll a

Question 18

This gives yellowish green color.

Answer 18

Chlorophyll b

Question 19

Responsible for colors red, purple, and blue in fruits and vegetables.

Answer 19

Anthocyanin

Question 20

no help in photosynthesis but their bright color attracts
pollinators

Answer 20

Anthocyanin

Question 21

This pigment produces bright yellow, red, and orange colors in plants, fruits, and vegetables. Ex. Carrots, oranges, Pumpkins, papaya

Answer 21

Carotenoid

Question 22

Major Pigments

Answer 22

• Chlorophyll a
• Carotenoid

Question 23

Two Stages of Photosynthesis

Answer 23

• Light-dependent
• Dark-dependent/ Calvin Cycle/ Light-Independent

Question 24

The sunlight/light source is converted to chemical energy during these reactions.

Answer 24

Light-dependent Reaction

Question 25

Light-dependent Reaction happens in

Answer 25

thylakoid membrane

Question 26

packet of light.

Answer 26

photon

Question 27

• group of pigments and proteins found in thylakoid membrane.
• has more chlorophyll a than b.
• goes first before photosystem I

Answer 27

PHOTOSYSTEM II

Question 28

• group of pigments and proteins found in thylakoid
  membrane.
• has more chlorophyll b than a
• found first so it is named Photosystem ….

Answer 28

PHOTOSYSTEM I

Question 29

the splitting of a chemical compound by means of light energy or photons (ex. H20)

Answer 29

PHOTOLYSIS

Question 30

a series of protein complexes found in the thylakoid membrane.

Answer 30

ELECTRON TRANSPORT CHAIN

Question 31

occurs when the concentration of particles is higher in one area than another.

Answer 31

CONCENTRATION GRADIENT

Question 32

movement of ions from higher to lower concentration

Answer 32

CHEMIOSMOSIS

Question 33

an enzyme that catalyzes the synthesis of ATP
from ADP and inorganic phosphate.

Answer 33

ATP SYNTHASE

Question 34

electron carrier, accepting electrons and hydrogen
atoms to form NADPH.

Answer 34

NADP (Nicotinamide-adenine dinucleotide phosphate)

Question 35

STAGES OF THE LIGHT DEPENDENT REACTION

Answer 35

Stage 1: Excitation of Photosystems and Photolysis of Water

Stage 2: Generation of ATP by Electron Transport Chain

Stage 3: Formation of NADPH

Question 36

IMPORTANCE OF LIGHT-DEPENDENT REACTION

Answer 36

1. Production of oxygen for animals and humans (Note: Phytoplankton are the major contributors of oxygen; they are microscopic algae that can perform photosynthesis)
2. Production of ATP for plants
3. Production of materials needed for Calvin cycle (ATP and NADPH).
