Plants - Photosynthesis/ respiration

Question 1

Waxy Cuticle

Answer 1

Helps reduce water loss from evaporation

Question 2

Epidermal tissues (Upper)

Answer 2

-Transparent
allows sunlight to pass through to the palisade layer which is full of chloroplasts

Question 3

Palisade Layer

Answer 3

Lots of chloroplasts , increases photosynthesis
Top of the leaf

Question 4

Xylem and Phloem Tubes

Answer 4

Xylem- Transport water to the stem to the leaves (TRANSPIRATION)
Phloem- Transports sugars/minerals all around the plant (TRANSLOCATION)

Question 5

Lower Epidermis

Answer 5

Small holes called stomata to allow CO2 to enter directly into the leaf

Question 6

•Guard cells

Answer 6

Control gas exchange and water loss

Question 7

Adaptations of Phloem tubes

Answer 7

• pores (enable movement of cell sap)
• easily transported
• stored food for later
• used directly for energy

Question 8

Adaptations for Xylem tubes

Answer 8

• One long tube
• strengthened by lignin

Question 9

Rate of transpiration

Answer 9

Light intensity
Temperature
Humidity
Air flow

Question 10

Respiration Definition

Answer 10

An EXOTHERMIC reaction that transfers energy from glucose and continuously occurs in living cells

Question 11

Aerobic Respiration

Answer 11

• Breaks down glucose releasing energy (ATP)
•Happens mainly in humans/ animals

Question 12

Anaerobic respiration

Answer 12

•In place of lack of oxygen

Question 13

Formula for Aerobic respiration

Answer 13

Glucose + Oxygen -> Water + Carbon dioxide
C6H12O + O2 -> 6H2O + 6CO2

Question 14

Formula for anaerobic respiration

Answer 14

IN LACK OF OXGYEN
glucose -> lactic acid
PLANT AND YEAST CELLS (fermentation)
glucose -> ethanol + carbon dioxide

Question 15

Uses of fermentation

Answer 15

Bread
Yeast
Alcohol
