Term | Definition |
Leaf | plant organ that carries out photosynthesis |
Epidermis(leaf) | Single layer of cells on top/bottom of leaf (protects leaf from drying out/UV rays/bacteria) |
Cuticle | layer of wax secreted by epidermal cells (Wax proofing reduces water loss) |
Stomates | Allow gas transfer in/out of leaves |
Guard Cells | Surround stomates(one on each side) Regulate opening/closing |
Parenchyma Cells | In a leaf located between upper/lower epidermis (carry out photosynthesis/ used as storage |
Palisade Parenchyma | Tightly packed (near top of leaf) |
Spongy Parenchyma | Loosely packed |
Palisade Mesophil | A tissue (Made up of many Parenchyma cells/rod-shaped) |
Spongy Mesophil | A tissue (Made up of Spongy Parenchyma/spaces between cells) |
Vein | Two types of tissues/both transport fluid (Xylem/Phloem) |
Trichomes | Extensions of epidermal cells (deter predators/help trap water vapor on surface) |
Buliform Cells | Large cells on upper epidermis (help the leaf to curl to create shade and cool it off/minimize water loss) |
Blade | Flat leaf part |
Petiole | Stalk like part that connects leaf to stem |
Cotyledon | Leaf that was first to emerge after growing (stores nutrients before plants germinate) |
Hypocotyl | The part of the shute of the plant below the cotyledon |
Flower | Plant organ which aids in reproduction |
Stigma | Top part, Pollen attaches to this part |
Style | Stalk like part, transfers sperm to egg (under stigma) |
Ovary | Produces egg within ovule (under style) |
Pistil | All female parts collectively |
Anther | Top male part (produces pollen) |
Filament | Stalk like part (Holds anther up so pollen is more likely to attach) |
Stamen | All male parts collectively |
Petals | Attract pollinators (colorful to attract) |
Sepals | Protects flower bus before flower opens |
Root | Plant organ designed for water absorption and anchoring |
Root Cap | Bottom most part of plant, protects the apical meristem from abrasion |
Apical Meristem | Small circular part center above the root cap, carries out cell decision to replace root cap cells that got rubbed off/ allow root to get longer |
Protoderm | Matures into the epidermis (single layer of cells one layer above root cap cells) |
Epidermis(root) | Increase surface area for water absorption, protects UV light. fungi |
Procambium | Cell layers directly above the apical meristem, matures into vascular tissue |
Root hairs | Extensions of epidermal cells that aid in water absorption |
Ground Meristem | Left and right of pro cambium, matures into ground tissue |
Ground Tissue | Above the ground meristem, stores starches |
Endodermis | 1 layer of cells that forms a ring around the vascular cylinder and regulates what gets into the vascular cylinder |
Zone of cell division | Bottom most part of the root (Apica, Protoderm, Ground Meristem) |
Zone of Elongation | Middle Zone (Cells Elongate) |
Zone of Maturation | Top most zone (Xylem can now transfer water, Phloem transfer sap) |
Stem | Lack stomates/epidermis, Vascular tissue on outside |
Collenchyma Cells | In between the epidermis and vascular bundles in dicot stem |
Sclerenchyma Cells | Very thick cell walls, top of vascular bundle |
Pith | Filled with Parenchyma Cells in dicots (storage) |
Cortex | Space in between epidermis and vascular bundles |
Bark | Inner bark=Phloem(transport sap) |
Springwood | Larger cells |
Summerwood | Smaller cells |
Lateral Meristem | (vascular cambium) New cells form here/ make xylem and phloem each growing season |
Xylem | found in wood transport water |
Phloem | found in inner bark transport sap |
tracheids | Cells that transport water in non-flowering plants |
Vessel Members | Big cells in xylem that transport water in flowering plants |
Sieve Elements | Transport sap in inner bark (lose nucleus when mature, no longer have DNA to make protein) |
Companion Cells | Make protiens for sieve elements (small cells attached to sieve elements in angiosperms) |
Albuminious Cells | Make proteins for sieve elements in gymnosperms |
Resin Ducts | Big holes found in outer bark layer of gymnosperms, transports resin |
Gymnosperm | Non-flowering plant that produces seeds on cones (pinecones) No vessel member, has albuminous cells |
Angiosperm | Flowering Plant which produces seeds in fruit No resign ducts, has companion cells |
