Answer 7

internal transport system made of xylem and phloem
can grow very tall
2 types

Answer 8

vascular plants
prehistoric
spores found under fronds/leaves
fiddleheads

Question 9

"naked seed"
seeds found in cones
conifers
wood is good for construction

Question 10

Answer 10

sexual reproduction through seeds

Question 11

identifying conifers

Answer 11

Jack pines

Answer 12

pioneer species

first to grow after a fire

Answer 13

vascular
flowering plants
most common type of plant
seeds found in fruit structure

1. monocots

2. dicots

Question 15

perennial plants

Answer 15

herbacious plants
live for a long time
stems and leaves die every year
roots don’t die

Question 16

biennial plants

Answer 16

Answer 19

seeds have two cotyledons (like peanuts)
flowers: groups of 4 or 5
roots: tap root, long and thick
veins: branch in all directions
vascular tissue: ring around stem
lifetime: usually more than one year

Question 20

monocots

Answer 20

seeds contain one cotyledons (like corn kernels)
flowers: groups of 3 or multiples of 3
veins: parallel to each other
roots: fibrous, spread out
vascular tissue: bundles around stem
lifetime: one year

Question 21

non-vascular plans

Answer 21

no internal transport system
must be in contact with water
very short
not very diverse

algae/seaweed

Answer 22

non-vascular
aquatic
fresh and saltwater
green, red, brown
contain chloroplasts
some have air bladders
many uses

Question 23

uses of algae/seaweed

Answer 23

agar- grows bacteria
food- high in vitamins and minerals
carrageenan- thickener in dairy products
bio fuel- being developed
control and clean up polutants

Question 24

moss

Answer 24

non-vascular
terrestrial
carpet-like
very short
pioneer organisms
no flowers
sexual reproduction through spores

Question 25
