Question 1

cell wall

Answer 1

used for protection and structure

Question 2

chloroplasts

Answer 2

energy production and carbon assimilation

Question 3

dermal

Answer 3

outer covering modifies for protection ans water absorption. trichomes are outgrowth of epidermis on leaves and secrets secondary compounds

Question 4

vascular

Answer 4

tranporter for long distance of material within the plant and includes xylem and phloem

Question 5

ground

Answer 5

is between dermal and vascular tissue. within vascular tissue is called pith and external is cortex

Question 6

translocation

Answer 6

is the movement of compounds trough phloem
phloem transport sugars form their site of synthesis to where they are needed

Question 7

tranpiration

Answer 7

movement trough xylem
xylem moves water and minerals from roots into shoots

Question 8

methods used to study metabolic pathways

Answer 8

radioisotopes to label precursors, use of plant cell cultures to produce pathway enzymes and molecular techniques

Question 9

primary metabolic pathways

Answer 9

creates molecules that are essential for life. mostly used in normal cell functioning and are not toxic to predators

Question 10

secondary metabolic pathways

Answer 10

Are processes that create molecules that are not required for the general functioning of the organism. usually used for defense
