transport in plants

Question 1

Why do plants need a transport system?

Answer 1

-meeting metabolic demands
-large size
-small SA:V ratio

Question 2

Chlorenchyma

Answer 2

cortex is made of chlorenchyma

Question 3

Schlerenchyma

Answer 3

cap that protects the phloem

Question 4

Parenchyma

Answer 4

packing cells

Question 5

What is a cotyledon?

Answer 5

A significant part of the embryo within the seed of a plant
-usually becomes the embryonic first leaves of a seedling upon germination
-the number of cotyledons can be used by botanists to classify the flowering plants (angiosperms)

Question 6

Where is the cambium located?

Answer 6

in between the phloem and xylem layers

Question 7

Phloem location

Answer 7

on the outside in roots and stems but underneath in the leaf

Question 8

Xylem location

Answer 8

on the inside in roots and steps but on top in leaves

Question 9

Characteristics of a monocot

Answer 9

-one cotyledon in seed
-flower parts in threes or it’s multiples
-vascular bundles scattered in stem
-parallel leaf veins

Question 10

Characteristics of a dicot

Answer 10

-two cotyledons in seed
-flower parts in fours,fives or their multiples
-vascular bundles in a definite ring
-leaf veins form a net pattern

Question 11

Mechanism of water transport from roots through plant

Answer 11

-water is lost by evaporation/transpiration
-Water moves by the symplast and Apoplast pathways
-up stem by cohesion-tension/ root pressure/ capillary action
-water loss reduces the water potential of leaf cells
-water moves from higher water potential to lower water potential down the water potential gradient through the symplast pathway by osmosis through plasmodesmatap
