Plant Tissues
Biology
| Tissue and Type | Location and Function |
|---|---|
| Covering- Epidermis | Leaf, stem, root; Protect, prevent moisture loss, form root hairs on roots |
| Covering- Bark | Woody stem; protect, prevent moisture loss, form root hairs on roots |
| Conducting- Xylem | Fibrovascular bundles in leaf, stem, root; Conduct water up from root into stem, leaves. |
| Conducting- Phloem | Fibrovascular bundles in leaf, stem, root; Conduct food from leaves to rest of plant |
| Growing- Meristem | Tips of stems, roots; growth, differentiation |
| Growing-Cambium | Fibrovascular buncles, between xylem and phloem; growth in thickness, formation of new xylem, phloem |
| Food-making - Palisade cells | Upper layer of leaf; photosynthesis |
| Food-making - spongy layer | lower layer of leaf; some photosynthesis, help circulate gases for palisade layer |
| Food-making - Green Cells | Stems; photosynthesis |
| Supporting- Wood | Xylem; mechanical support |
| Supporting- Thick-walled living cells | Leaf, stem (under epidermis); mechanical support |
| Supporting- Thick-walled dead cells | Stem, outside of phloem; mechanical support |
| Supporting- Thin-walled, large cells | Leaf, stem; suport by turgidity |
| Storage- Pith cells | Stems; store food |
| Storage- Root tissue | Enlarged roots; store food |
| Reproductive- Pollen | Stamen of flower; produce sperm nuclei |
| Reproductive- Ovule | Ovary of flower; produce egg nuclei |
