Chapter 7: Photosynthesis

Front 1

Photosynthesis

Back 1

Is a process whereby plants, algae and certain bacteria transform light energy into chemicals energy using carbon dioxide and water.

Hint 1

Is an end endergonic reaction.Photo

Front 2

Photosynthesis

Back 2

Converts carbon dioxide and water into glucose and oxygen using sunlight.

Front 3

Epidermis

Back 3

Upper and lower surface of the leaf.

Front 4

Cuticle

Back 4

Waxy, waterproof covering that reduces the evaporation of water from the leaf

Hint 4

Starts with a C

Front 5

Stomata

Back 5

Opening in the surface of the leaf that allows gases and water to pass into and out of the leaf

Front 6

Mesophyll cells

Back 6

“ middle leaf” these cells contain the majority of the chloroplasts

Front 7

Vascular bundles or veins

Back 7

Supply water and mineral to the minerals to the mesophyll cells and carry the sugar they produce.

Front 8

Chloroplasts

Back 8

Double membrane organelle

Front 9

Stroma

Back 9

the liquid portion of the chloroplast where light independent reaction occurs

Hint 9

Sugar is produced

Front 10

Thylakoid membrane

Back 10

an interconnecting membrane inside the chloroplasts where the light dependent reactions occur.

Front 11

Photons

Back 11

Package of light energy

ROYGBIV

Front 12

Short Wavelength

Back 12

Have high energy

Front 13

Long wavelength

Back 13

Have low energy

Front 14

Chlorophyll a

Back 14

Reflects green light, absorbs blue and violet light.

Directly involved in photosynthesis

Front 15

Chloroplasts b

Back 15

Reflects yellow-green light absorbs blue and orange light.

Broadens the amount of light energy that can be used for photosynthesis.

Hint 15

Broadens the amount of light energy that can be used for photosynthesis.

Front 16

Carotenoids

Back 16

Accessory pigment

Protects our eyes from UV light

Passes energy to Chlorophyll a

Front 17

Photosystems

Back 17

Are found in the thylakoid membrane and are composed of proteins, accessory pigment molecules and electron- carries molecules.

Front 18

Electron Transport System

Back 18

A series of elections carries molecules.

Front 19

Thylakoid membrane

Back 19

ATP and NADP are produced

Water is split and oxygen is released.

Front 20

Light is ?

Back 20

absorbed , refleted or transmitted through the leaf.

Front 21

Light is absorbed by the following pigments

Back 21

Chlorophy II

carotenoids

phycocyanins

Front 22

Photosystems I and II

Back 22

PII-P680

PI-P700

Front 23

ETS location

Back 23

Embedded within the thylakoid membranes of chloroplasts next to a light harvesting complex.

Inner membrane of mitochondria.

Front 24

ETS functions

Back 24

extraction of energy from electrons and generation of ATP or ATP or other energetic molecules.

Front 25

Photolysis

Back 25

water is split and oxygen and electrons are released when light energy hits photosystems II. Photosystems II gets a replacement electron

Front 26

The lost electron from photosystem I ?

Back 26

is replace with an electron from the first ETS.

Front 27

In photosynthesis the chemiosmis production of ATP is called

Back 27

photophosphoryiaton

Front 28

In photosynthesis, the final electron acceptor ?

Back 28

is NAPH+ not oxyegn as in respiration

Front 29

Photolysis

Back 29

water is spilt

Front 30

____ and ____synthesized during the light dependent reactions are used to produced glucose from carbon dioxide and water in the stroma of the chloroplast.

Back 30

ATP and NADPH

Front 31

The capturing of carbon dioxide is called

Back 31

carbon fixation

Front 32

The stomata of plants not only allows gases to pass into or out of the leaf it also allows

Back 32

water to evaporate from the leaf.

Front 33

An enzyme that has a high affinity for CO2 combines with carbon dioxide to form what?

Back 33

oxaloacetate( carbon fixation)
