The anatomy of the plant
| Question | Answer |
|---|---|
| Dermal Tissue | the outer covering of the plant |
| What does the dermal tissue do? | Regulates movement of materials into and out of the plant |
| Ground tissue: | most of the plant body and provides support |
| Vascular tissue: | Xylem and Phloem cells, transport of materials through plant |
| Xylem: | Transports water fromthe roots to the other tissues of the plant |
| Ploem: | Transports the products of photo from leaves to plant |
| Meristematic tissue: | Where cell division takes place; provides the direction of growth |
| Nodes: | Regions from which leaves grow from stem |
| Internodes: | Areas of stem between nodes |
| Terminal buds: | Located at the tips of stems and branches |
| Axillary or Leteral buds: | Located in the nodes along stems; give rise to lateral branches |
| PARTS OF A LEAF | (blank) |
| Blade: | Part of a leaf, flattend part |
| Petiole: | The stalk that attaches it to the stem |
| Primary and secondary roots: | main root extending straight down from plant |
| Root hairs: | each hair is one cell bottom of plant root |
| THE STEM LONG SECTION | looks like a frog |
| The feeler like thing that grows like the legs of a frog... | Leaf Primordia |
| The Bulb like thing growing like the head of a frog.. | Apical meristem: |
| The little section of to the side, like a cresent..far away from the frog head | Xylem: |
| STEM CROSS SECTION, how would you recognize one | Looks like it has a non uniform cell volume. Too much stuff toward the side. The center is clearish. You would recognize one because of the fact that the side has teeny cells together... |
| Epidermis: | On the end |
| Vascular bundles: | Teeny cells together |
| Pith: | Center of the stem section |
| Fiber Bundle cap: | Whole thing near the end of cell |
| Phloem: | Makes up the vascular bundle: |
| Xylem: | BIGGER CELLS |
| ROOT, WHAT IS IT ALSO KNOWN AS, and how do you recognize one | Has stuff in center, otherwise uniform TURTOX. You can recognize a root because of the fact that it has pinkish gray large cells with greenish phloam |
| VAscular cylinder: | central thing, around the X |
| Xylem: | The X in the center, Large pinkish gray cells |
| Phloem: | Greenish blue |
| Casparian strip:: | Surrounds each cell of the endodermis |
| Cortex | Tissue around the outside of the endodermis, function: starch storage |
| THE LEAF LEAF LEAF | like a rectangle VERY DARK PINK, LAYERED |
| UPPER Epidermis: LOWER EPIDERMIS: | Upper: It is thick, at the top of cell Lower: It is thinner, at the bottom of cell |
| Vascular Bundle: | The circular thing in the middle, very dark pink, smushed together |
| Stomato: | The hole in the wall almost shaped like a snowflake |
| Guard cells: | The surrounding wall around cell--Blue stuff around the hole |
