Plants WS (roman numerals 1-3)

1.     Draw a pie chart of all known species.  Include: Insects, other animals, plants, fungi and “other”.

2.    Are there more vascular or non-vascular plants?  Vascular

3.    Are there more angiosperms or gymnosperms? Angiosperms

4.    Are there more monocots or dicots? Dicots

5.    Look at the samples that your teacher has collected.  Draw a quick sketch of the plant, then check all that are true for the plant you are looking at:

a.   (maple) __x__ vascular; ___ nonvascular; __x_has seeds; ___has spores; __x_ angiosperm; ___gymnosperm; ___monocot;_x__ dicot

b.    (pine tree)__x__ vascular; ___ nonvascular; __x_has seeds; ___has spores; ___ angiosperm; _x__gymnosperm; ___monocot;___ dicot

c.  (moss)  ____ vascular; _x__ nonvascular; ___has seeds; __x_has spores; ___ angiosperm; ___gymnosperm; ___monocot;___ dicot

6.    Which of the following are true of the alternation of generations?

a.    ___x__ this is most easily seen in ferns

b.    _____ The sporophyte generation has half the DNA.

c.    __x___ The gametophyte generation has half the DNA.

d.    _____ The sporophyte generation uses egg and sperm to reproduce.

7.    Draw a picture that illustrates the gametophyte and the sporophyte generations in either a tulip,  a moss or a fern.  Label the generations.

(moss) 

(fern, more info than we need)

8.    Vascular plants have ___veins___ and Non-vascular plants don’t.

9.    Sporophytes have ____the full number / 100%________ of chromosomes.

10. Gametophyte plants have ______half the number / 50%______ of chromosomes.

11. Define:

a.    Diploid - having the full number of chromosomes

b.    Haploid- having half the number of chromosomes

12. List 3 characteristics of vascular plants: they have veins and roots, they are taller, they are sporophyte dominant, most of them use seeds to reproduce

13. Vascular plants can be divided into two groups.  These groups are: those that use seeds and those that use spores

14. Plants with seeds can be divided into two groups.  These groups are:  gymnosperms and angiosperms

15. Angiosperms can be divided into two groups.  These groups are: monocots and dicots

16. Draw a picture of a monocot leaf and a monocot flower.

17. Draw a plant map and include these words:  See the image in post which is below

Gymnosperm and Angiosperm

Monocot and Dicot

Seeds and spores (or no seeds)

The four kingdoms

The three domains

Vascular and non-vascular

18. Place the following plants somewhere on the plant map: rose, pine tree, moss

          rose is a dicot, pine tree is a gymnosperm and moss is a nonvascular plant.
