Question 1

photosynthesis

Answer 1

This happens in the leaves, (plated cell -> chloroplast), which must balance the need to maximize photosynthesis with the the problem of drying out
If they were in the shade most of the day, they would try and make the most food they can while they were in the sunlight

Question 2

leaf cross-section functions

Answer 2

• Cuticle
  Wax coating to prevent water loss
• Sponge cells
  Spongey for gas and water to pass through
• Stomach
  Allows gas to exit

Question 3

types of symmetry

Answer 3

Radical Symmetry
A body plan that is divided along any plane through the central axis in roughly equal halves
Bilateral Symmetry
A body plan that is dived through one plane into equal halves

Question 4

cross-section of leaf/stem/root what type it is (monocot or dicot)

Answer 4

Root
Monocot
Xylem and phloem alternate in a ring pattern around the pfit
Dicot
The xylem is in a star pattern and the phloem is in between the arms of the xylem
Stem
Monocot
Vascular bundles are scattered
Dicot
Vascular bundles arranged in a ring

Question 5

prophase 1 meiosis

Answer 5

Crossing over of the genetic
Important for genetic variation

Question 6

how do you know if leaves are monocots or dicots?

Answer 6

monocot
parallel veins
dicot
netlike veins

Question 7

inhalation and exhalation

Answer 7

Inhalation
Dispahram muscle contracts pulling downward
Exhalation
Diaphragm muscles and external intercostal muscles retract to the ribcage moving inward and downward
