| Question | Answer |
|---|---|
| Define Botany | the study of plants |
| Define Perennial Plants | plants that grow year after year |
| Define Annual Plants | plants that live only one year |
| Define Biennial Plants | plants that live for two years |
| Define Vegetative Organs | the parts of a plant(such as stems, roots and leaves) that are not involved in reproduction |
| Define Reproductive Plant Organs | the parts of a plant(such as flowers, fruits, and seeds) involved in reproduction |
| Define Undifferentiated Cells | cells that have not specialized in any particular function |
| Define Xylem | nonliving vascular tissue that carries sugar and organic substances throughout a plant. |
| Define Leaf Mosaic | the arrangement of leaves on the stem of a plant |
| Define Leaf Margin | the characteristics of the leaf edge |
| Define Deciduous Plant | a plant that loses its leaves for winter |
| Define Girdling | the process of cutting away a ring of inner and outer back all the way around a tree trunk |
| Define Alternation of Generations | a life cycle in which there is both a multicellular diploid form and a multicellular haploid form |
| Define Dominent Generation | in alternation of generations, the generation that occupies the largest portion of the life cycle |
| Define Pollen | a fine dust that contains the sperm of seed-producing plants |
| Define Cotyledon | a "seed leaf" which develops as a plant of the seed. It provides nutrients to the developing seedling and eventually becomes the first leaf of the plant |
| If a portion of a plant is producing new cells, what type of plant tissue will be in that region? | Meristematic tissue |
| What do we call the structure that attaches the blade of the leaf to the stem? | Petiole |
| In a leaf, what is the function of the following tissue: plaisade mesophyll, spongy mesophyll, epidermis, xylem, phloem, and collenchyma. | palisade meso.- maximize the number of cellsspongy meso.- take up space. Epidermis- protection. Xylem- Transport water and minerals. Phloem- Transports sugars and organic substances. Collenchyma- Protection |
| What controls the opening and closing of the stomata on a leaf? | Guard Cells |
| Why is the bottom of the leaf typically a lighter shade of green than the top of the leaf? | the Spongy Mesophyll |
| Name two types of pigments that cause leaves to be a color other than green. | Caroenoids and Anthocyanins |
| If a tree has no abscisson layer, will it be deciduous? | no |
| Where is the abscisson layer? | at the base of the petiole |
| Name the four regions of a root. Which region contains undifferentiated cells? | Maturation, Elongation, Meristematic, and Root Cap; Meristematic has the undifferentiated cells |
| What allows woody stems to have no limits to their growth, unlike herbaceous stems? | because new bark can be created. |
| What is the function of vascular cambium? | it produces new vascular tissue |
| If a stem has cork cambium, is it woody or herbaceous? | woody stem |
| What kind of vascular tissue makes up most of the wood in a woody stem? What kind of vascular tissue is found in the inner bark of a woody stem? | Xylem ; Phloem |
| What is the dominent generation in the moss life cycle? Is it haploid or diploid? | Gametophyta ; Haploid |
| A fern has antheridia and archegonia. Which part if the fern life cycle is it in? Is this the dominent generation? | Gametophyte ; No |
| Why are plants from Bryophyta relatively small? | because it has no vascular tissue so it doesnt have efficent way to transport nutrients |
| If a 15-foot tall plant has a root system that goes four feet deep, is it fibrous and taproot system? | fibrous root system |
| What are the male and female reproductive organs from phylum Coniferophyta? | female- Seed Cone ; Male- Pollen Cone |
| What is the fundamental difference between monocots and dicots? | the number of cotelydons |
| Name the other difference betweem monocots and dicots. | venations, root systems, and flowers |
| A plant produces seed cones and pollen cones. Is it vascular? To what phylum does it belong? | Vascular ; Coniferophyta |
| A plant produces flowers. To what phylum does it belong? | Anthophyta |
