| Question | Answer |
|---|---|
| botany | the study of plants |
| perennial plants | plants that grow year after year |
| annual plants | plants that live for one year |
| biennial plants | plants that live for two years |
| vegetative organs | the parts of a plant(such as stems, roots, and leaves) that are not involeved in reproduction |
| reproductive plant organs | the parts of a plant(such as flowers, fruit, and seeds) involved in reproduction |
| undifferentiated cells | cells that have not specialixed in any particular functions |
| xylem | nonliving vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves |
| phloem | living vascular tissuueu that carries sugar and organic substances throughout a plant |
| leaf mossaic | the arrangement of leaves on the stem of a plant |
| leaf margin | the characteristics of the leaf edge |
| deciduous plants | a plant that loses its leaves for winter |
| girdling | the process of cutting away a ring of inner and outer bark all the way around a tree trunk |
| alternation of generations | a life cucle in which there is both a multicellular diploid form and a multicellular haploid form |
| dominant generation | in alternation of generations, the generation that occupies the largest portion of the life cycle |
| pollen | a fine dust that contains the sperm of seed-producing plants |
| cotyledon | a "seed leaf" which develops as part of the seed- it provides nutrients to the develping seedling and eventually becomes the first leaf of the plant |
| 2. if a portion of a plant is priduucing new cells, what type of a plant tissue will be in that region? | meristematic tissue, because anywhere mitosis is going on it will be there. the cells that perform mitosis are in the part of ther meristematic tissue. |
| 3. what do we call the strucure that attaches the blade of the leaf to the stem? | the petiole |
| 4. | a. whorled b. alternate c. opposite |
| 5. determine the shape, margin, and venation of the following leaves: | a. deltoid,entire,parallel b. elliptical, serrated, pinnate c. lobed, entire, pinnate d. cleft, denatate, palmate e. orbicular, undulate, innate f. chordate, entire, pinnate |
| 6. in a leaf, what is the funtion of the following tissue? a) palisade mesophyll b) spongy mesophyll c)epidermis d)xylem e) phloem f)chollenchyma | a)photosynthesis b)photosyntheses c)protection d) transports whater and minerals e)transports food and substances f) support |
| 7. what controls the opening and closing of the stomata on a leaf | the gaurd cells control the opening and closing of the stomata |
| 8. why is the bottomw of a leaf typically a lighter shade of freen than the top of leaf? | the spongy mesophyll is typically on the underside of the leaf, due to the fact that the photosynthesis cells are not as tightly packed there |
| 9. name two types of pigments that causes leaves to be a color other than green | carotenoids and anthocyanins |
| 10. if a tree has no abscission layer, will it be deciduous? | no |
| 11. where is the abscission layer | right between the stem and the petiole |
| 12. name the four of a root. which region contains undifferent cells? | root cap, the meristematic region, the elongarion region, and the maturation region. the undifferent cells are in the meristematic region |
| 13. state which of the following stem cross sections came from a monocot and which came from a dicot | a. from a dicot b. is a monocot |
| 14.what allows woody stems to have no limits to their growth, unlike herbaceous stems? | because of the cork cambium can always produce more bark |
| 15. what is the function of vascular cambium? | it produces new vascular tissue |
| 16. if a stem has cork cambrium is it woody or herbaceous? | woody |
| 17. what kind of cascuular tissue makes up most of the wood in a woody stem? | zylem make up most of the wood in a woody stem, while pjloem are found in the innerbark |
| 18. what is the dominant gereation in the moss life cycle? is it haploid or diploid? | the dominant generation is mosses is the gametophyte, and it is haploid |
| 19. a fen has antheridia and archegonia, which part of the fern life cucle is it in? is this the dominant generation? | it is in the gametophyte generation, which is not the dominant generation |
| 20. why are plants from phulum bryophyta relatively small? | since plants from that phylum have no vascular tissue there is noefficient way to transport nutrients throughout the plant |
| 21. if a 15-foot tall plant has a root system that foes four feet deep, is it fibrous of taproot system? | fibrous |
| 22. what are the male and female reproductive organs in a tree from phylum coniferophyta? | female is the seed and male is the pollen cone |
| 23. what is the fundamental difference between monocots and dicots? | the number of cotyledons produced in the seed |
| 24. what is another difference between monocots and dicots? | monocots the benation is parallel while in dicots it is netted. the fibrovascular bundles are packaged differently. monocots have fibrous root systems whereas dicots have taproot. and monocots usually produce flowers in groups of 3 to 6 and dicots 4-5 |
| 25. a plant produces seed cones and pollen cones. is it vascular? th what phylum does it belong? | Coniferophyta |
| 26. a plant produces flowers to what phylum does it belong? | Anthophyta |
