8.1,8.2,8.3,8.4 Flashcards
1
Q
xylem location
A
- located inside root and stem
2
Q
phloem location
A
- phloem is outside roots and stem
3
Q
xylem function
A
- transports minerals and water from the roots
- provides support for transpiration (where water leaves leaf)
4
Q
phloem
A
- made of living cells
- involves in translocation
- two way flow
- transports food (glucose, sucrose) from leaves to other parts of the plants
5
Q
vascular bundle
A
made up of phloem and xylem
6
Q
process after light goes into chlorophyll
A
1) converts to chemical energy -> glucose is produced > converted to sucrose for TRANSLOCATION -> starch is stored in roots
7
Q
factors that affect rate of transpiration
A
- wind speed
- temp
- humidity
- water supply
- light and latitude
8
Q
translocation
A
- has nothing to do w water
- movement of organic matter e.g: sucrose, glucose, amino acid
9
Q
auxin
A
- found in the tip of a root/shoot
- promotes cell elongation (growth)
- sensitive towards cell
- a type of hormone
10
Q
xylem characteristics
A
- made of many dead cells
- hollow lumen- more surface area for water
- made of thick lignin cell wall
- one way flow
11
Q
transpiration
A
-process by which moisture is carried through plants
from roots to the stomata
- essentially evaporation of water from plant leaves
