Answer 19

mosses are the most primitive types of plants.

Question 20

Moss does not have what typical plant structure?

Answer 20

Moss does not have a vascular system which is how plants transport water.

Question 21

How do mosses get their nutrients, water and minerals?

Answer 21

Moss gets nutrients, water and minerals through osmosis.

Question 22

What is osmosis?

Answer 22

Osmosis is the process where water moves from a place with lots of water to a place with less water to even out the water amounts

Question 23

How are mosses held to the ground?

Answer 23

Moss has root-like threads that help anchor the plant without absorbing nutrients or water like roots do.

Question 24

Do mosses have roots?

Answer 24

No, moss does not have roots.

Question 25

Why does moss grow close to the ground?

Answer 25

Moss grows close to the ground because they cannot carry water up the plant structure

Question 26

Where do mosses grow?

Answer 26

Moss grows in damp shady areas in clumps

Question 27

What does moss have in common with lichens?

Answer 27

Moss and lichens are the first plants to grown in rocky ground, and they can break apart rocks allowing the early stages of soil formation.

Question 28

How does moss help prevent soil erosion?

Answer 28

Moss absorbs many times its size in water, so captures rainfall.

Question 29

Which plant is more advanced than moss?

Answer 29

Ferns are slightly more advanced than moss.

Question 30

Unlike moss, ferns have a…

Answer 30

Ferns have a vascular system to transport water.

Question 31

What moves water around the fern?

Answer 31

xylem is a transport tissue that moves water around the plant

Question 32

What moves nutrients around the fern?

Answer 32

phloem moves nutrients, particularly sugar, around the plant.

Question 33

Unlike moss ferns also have…

Answer 33

roots that absorb water and nutrients.

Question 34

How is water and nutrients transported around the plant?

Answer 34

Stems and leaves via the xylem and phloem transport the nutrients and water.

Question 35

What are ferns known for?

Answer 35

Ferns have fiddleheads, the curled up leaves of young ferns.

Question 36

Where do ferns grow?

Answer 36

Ferns grow on mountains, crevices, swamps and moist forests.

What is the most common fern?

Answer 37

The most common fern is bracken fern.

Question 39

Conifers includes..

Answer 39

pines, cedars,junipers, spruces and other trees.

Question 40

What do conifers have in common?

Answer 40

They are woody, have cones and needles (needles are long pointy leaves), they are evergreen.

Question 41

Do conifers lose their leaves?

Answer 41

No, they stay green but over the winter they slowly replace their old leaves (needles)

Question 42

How does the waxy coating on pine needles help the tree?
