The moss known as ____________, forms peat moss which can be used as a source of fuel. It is also used to improve moisture of soil.

Sphagnum

5

The ____________ belong to a special group of plants that do have vascular but do not produce seeds. They produce spores to fertilize "eggs".

Ferns

6

Vascular tissue is composed of ______________ tissue which conducts water and minerals. It is also composed of __________ tissue which conducts sugars from one part of the plant to another.

Xylem, Phloem

7

The most plentiful plants in the biosphere are the _______ ____________.

Seed plants

8

Name three parts of a seed:

Seed, coat, sporophyte embryo, stored food

9

Describe how does pollination occur:

Flowers that have Male reproductive parts are called Stamens that produces a sticky powder called pollen. Flowers that have the female reproductive parts called a pistil needs to be pollinated by pollen that is moved from stamen today stigma.
