Question 29

Xylem

Answer 29

tissue that conducts water and minerals

Question 30

Where is primary xylem located

Answer 30

procambium

Question 31

where is secondary xylem located

Answer 31

vasc cambium

Question 32

are treacheids alive or dead at maturity

Answer 32

dead

Question 33

tracheids

Answer 33

cells that transport water and minerals, diff from parenchyma cells

Question 34

what does a tracheid cell look like

Answer 34

elongated thick cell walls inside hollow = water movement pits in cell wall so fluid can move from one cell to the next

Question 35

vessel elements

Answer 35

conduct water and minerals dead at maturity shorter and wider than tracheids fully open ho;es where two cells meet = less friction

DOes every sieve tube member have a companion cell

Answer 41

yes

Question 42

Do sieve tube members have a nucleus

Answer 42

no

Question 43

Compainion cells

Answer 43

next to sieve tube elements sends message to manage sieve tube elements

Question 44

Glandular cells

Answer 44

Secretory cells Formed from parenchyma cells More ER and dictyosomes Lots of sugars and minerals
