Plant Review
1. What type of plant is this?
A. moss
B. fern
C. gymnosperm
D. angiosperm
Sporophyte
(spores)
2. Which group of plants does not have vascular tissue?
_bryophytes____________________
3. Mosses:
A. need water to reproduce.
B. have no true roots, stems, or leaves.
C. show alternation of generations.
D. all of these are true.
4. When do seeds and fruits develop?
A. before pollination and fertilization
B. after pollination and fertilization
C. before dormancy
D. after dormancy
Gametophyte
(gametes)
5. The veins found in leaves are made up of:
A. pith & cortex.
B. epidermis & heartwood.
C. cambium & cork.
D. xylem & phloem
6. This heart-shaped structure is characteristic of:
A. mosses B. fern s
C. gymnosperms
D. angiosperms
7. In our notes and lab, we discussed why water was necessary for these organisms.
What were these reasons? mosses – stay small/no vascular tissue;
Ferns: gametes must travel through water.
8. What major groups of organisms produce seeds for reproduction? Gymnosperms (pines) &
angiosperms (flowering plants)
9. The development of seeds reduced the need for what during reproduction? water
10. Reproduction involving seeds is: sexual
or
asexual
(circle one)
11. How do you know a flower is a monocot or dicot? Monocot flowers: petals/sepals in groups
of 3; dicots: petals/sepals in groups of 4 or 5
12. What do you call the green, leafy structure of a fern that is commonly used in flower
arrangements? frond
13. What structures are commonly found on the underside of the structures in #13? Sori containing
spores
14. What adaptation in the leaf is observed in the leaves of pine trees? Small thin; thick cuticle –
What advantages exist as a result of these types of leaves? reduce water loss & damage from
heavy snow
15. Pine trees are classified as what type of plants? Gymnosperms
16. Why are they classified as these types of plants? Means “naked seeds” – seeds are in cones not
fruit
17. How can you tell if a root cross section (slide) is a monocot or dicot?
Monocot root: ring (fibrous) dicot root: X or star (taproot)
18. What are the layers of the root called and what are their functions?
Epidermis: protection, water absorption
cambrium: growth
Phloem: transport food (glucose)
cortex: storage
Xylem: transport water
19. What is found at the end of the root tip and what is its function?
Root cap: protects growing root
20. What structures increase the surface area of roots? Root hairs
21. How can you tell the cross section (slide) of a monocot and dicot stem apart?
Monocot stem: scattered
dicot stem: ring
22. What makes up the vascular bundles? Xylem & phloem
23. The purpose of the vascular bundles: transport water & glucose (food)
24. What can tree rings tell you about a tree? Age, how much water was available (drought or rainy)
25. Differentiate between a taproot and fibrous root. Which is a monocot and which is a dicot?
Taproot: dicots; one main root with small roots coming off it
Fibrous root: monocots; many
tangled roots
26. The functions of roots are: water absorption, anchor
27. Does photosynthesis take place in stems? Explain your answer. Yes, if its green, then it has
chlorophyll which allows photosynthesis to take place
28. Label the parts of the leaf and their functions.
Epidermis (with cuticle)
Palisades (photosynthetic)
Mesophyll (air spaces)
Veins (xylem & phloem)
Lower epidermis
Stoma (with guard cells)
29. What is the main function of the leaf? Photosynthesis (and transpiration, too)
30. Xylem carries: water; Phloem carries: “food” (glucose)
31. Differentiate a fleshy fruit from a dry fruit: fleshy – soft tissue (berries, apples, etc)
Dry – no soft tissue (nuts)
32. Label the parts of the flower and what are their functions?
Petal
Carpel/pistil (stigma, syle, ovary with ovules)
Stamen (anther with pollen, filament)
sepals
33. The male part of the flower is called: stamen
The male part of the flower is made up of the anther
and filament.
34. The female part of the flower is called: carpel or pistil
The female part of the flower is made up of the stigma, style
and ovary (with ovules).
35. Where does fertilization take place in the flower? In the ovary
36. List some methods of seed dispersal and give an example of each:
Wind (dandelions, samaras)
Water (coconuts)
Animals (edible like apples & berries or stick to fur like burs)
37. Use your book to observe some modified stems. Be able to identify such stems and understand
their purpose. Potatoes, onions, corms, bulbs, cactus (for photosynthesis)
40. fertilized ovules develop into seeds.
41. Plants respond to light, touch and gravity. What are these responses called? phototropism,
thigmotropism and gravitropism
42. What controls the responses in #41? Auxins (plant hormones)
