| Question | Answer |
|---|---|
| What Is Biology? | The study of living things |
| what are the three studies of biology? | botony, zoology, human anatomy and physiology |
| what are aniosperms? | flowering seed plants |
| what are the four parts of an angiosperm? | flower,leaf,stem, root |
| What are the functions of each? | flowers reproduce, leaves make food, stems transport food and minerals, roots anchor plant and give it water |
| what are the three stem types? | woody,herbacious,vine |
| what are the two root systems? | fibrous, taproot |
| what are the three classes of growth cycles? | perennial,biennial,annual |
| what are the two types of grasses and the importance of each? | turf:is used to cover areas of landfood:they give us food |
| what is the deciduous plant? | It loses its leaves in the fall |
| what is a monocot? | it has one cotyledon |
| what is a dicot? | it has many cotyledon |
| what are the three basic shapes of leaves? | long and narrow, broad and flat, needlelike |
| what are the two parts of a leaf? | blad and petiole |
| What are the types of margins? | toothed, smooth, lobed |
| what are the veins? | they transport the food |
| what is a sessile? | leaf without a petiole |
| what is a stipule? | small leaflike structure that protects the leaf |
| what is a bud? | it covers the developing leaf. like a uterus |
| What is a simple leaf? | it has one petiole |
| what is a compound leaf? | it has more than one petiole |
| where does photosynthesis occur in the cell? | chloroplasts |
| What part of the plant does photosynthesis occur in? | the leaf |
| what is the molecule that has green pigment? | chlorophyll |
| what are the three types of leaf tissue? | structural, vascular, meristimatic |
| What are the three types of Structural tissue? | Epidermal,cork,parenchyma |
| What are the two types of vascular tissue? | Xylem, and Phloem |
| What is meristimatic tissue? | used for growth and repair. stem cells |
| What is the structural tissue? | The body of the plant. bones |
| What is the Vascular tissue? | the sap-conducting tissues. veins and arteries |
| What is the nucleus? | the control center for the cell |
| What is the cell membrane? | seperates the cell from its environment |
| What is the cell wall? | the outside of the cell membrane and protects the cell from outside force |
| What is chloroplasts? | where photosynthesis takes place in the cell |
| What is a stomata? | tiny holes in leaf that water passes in and out of |
| what are the guard cells? | they control the stomata |
| what is transpiration? | the loss of water in leaf through the stomata |
| what are the products of photosynthesis? | glucose and oxygen |
| what factors effect photosynthesis? | heat,water,sunlight,carbon dioxide |
| what is the most important factor in photosynthesis? | sunlight |
| Where does the oxygen in photosynthesis come from? | water, H2O |
| What is the cell wall made of? | cellulose |
| What are thylakoids? | stacks of specialized disks |
| What causes leaves to change color;what triggers it? | chorophyll deterioration; the days get shorter in the fall so that means less sunlight |
| what are the three secondary leaf pigments and what colors do they show? | xanthophyll:produces yellowish colorscarotene:produces yellowish orange colorsanthocyanin:produces bright red,blue and purple |
