Plant Structure and Transport in Plants
| Question | Answer |
|---|---|
| What system of plant is photosynthetic? | Shoot system |
| What do shoot systems have? | Chloroplasts and mitochondria |
| What do root systems have? | No chloroplast and mitochondria |
| What are the typical plants called? | Angiosperm |
| What type of angiosperm are there? | Monocot and dicot |
| What do monocots posses? | One cotyledon, have vascular bundle, fibrous roots, floral part in multiples of 3, parallel major vein that run length of blade |
| What do dicots posses? | Two cotyledon, petals in 5, veins netlike |
| Where do root systems store food? | Vacuoles and plastids |
| Where does 02 for cellular respiration come from? | Soil |
| Where does CO2 come from for shoot system? | Air |
| Where does water come from? | Roots who get water from soil |
| What roots support plant, extend exposure to soil water and minerals and anchor plant (monocots)? | Fibrous roots |
| What types of root have large vertical root that produce small lateral branches and roots and also store food? | Taproot |
| What type of root create more surface area to take up water and minerals with tiny hairs? | Root hairs |
| What roots are above ground and give support to trees? | Adventitious |
| Shoots consist of what? | Stems and leaves |
| What consists of blades and stalk? | Leaves |
| What attaches the blade to the stem node? | Petiole |
| What type of tissue has a single layer of tightly packed cells that cover and protect plant? | Dermal tissue or epidermis |
| Waxy substance made by dermal tissue that helps leaf retain water? | Cuticle |
| What type of tissue is continuous throughout plant and involved in transport of materials between roots and shoot? | Vascular tissue |
| What type of vascular tissue conveys water and dissolved minerals upward from root to shoot? | Xylem |
| What type of vascular tissue the transport food made in mature mature leaves to the roots and nonphotsynthetic parts of the shoot system? (down and sideways) | Phloem |
| What type of cells does the xylem have? | Tracheid and vessel elements |
| What is the function of the tracheid and vessel cells? | Support and water transport |
| Tracheid and vessel cells are: | Dead at functional maturity |
| What do tracheids and vessels have that interrupt their secondary wall and are in a thinner region where only primary walls are? | Pits |
| What is the function of pits? | Water can move easily in and out |
| What type of xylem cell is long and thin? | Tracheid |
| How does water move from cell to cell in vascular tissue? | Pits |
| What hardens secondary wall and function in support and transport in tracheids? | Lignin |
| What type of vascular tissue are wider, shorter, and thinner walled? | Vessel elements |
| What transports sucrose and organic compounds in phloem? | Sieve tube members |
| When vessel elements are aligned end to end they're called? | Xylem vessels |
| Sieve tubes are: | Alive, no nucleus, no vacuole and located in phloem |
| What is in between to sieve tube members in phloem? | Sieve plates |
| What do sieve plates do in Phloem? | Facilitate flow of fluid between cells |
| Two types of cells in phloem: | Companion cell and sieve tube members |
| What type of plant cell has primary walls, lack secondary cell wall, thin and flexible? | Parenchyma |
| Cell to elodea and fruit "typical" plant: | Parenchyma |
| Photosynthesis occurs within the chloroplast of this cell | Parenchyma |
