| Figure 1. illustrates the mutualistic relationship between the lichen fungi (white part) and moss. |
Moreover, Figure 1 also implies that the growth type of this lichen is "foliose" out of all two other types of growth including fruticose and crustose. It is foliose because the lichen fungi in Figure 1. seems to show leaf-like structures that loosely attach to the substrate.
Furthermore, this video also emphasizes on plant stem anatomy. It is learnt that there are multiple layers in a plant stem including "bark", "cambium", "sapwood", and "heart wood". One interesting layer of the stem is the cambium layer. This layer contains phloem and xylem which functions to transport nutrients and water by push and pull mechanism.
This field trip also touched on ectomycorhizal fungi and pathogenic fungi that can be beneficial and harmful to plants, and some medicinal values of fungi to human but can harm insects and/or plants. Due to my technological problems, I could not capture any images or videos regarding these fungi. I was an interesting field trip overall.
Hey Kyle, your posting is really interesting. Your post is so helpful to get knowledge. I wrote how was it and how was I during the field trip for majority part but you didn't. Awesome. I like that. Thank you Kyle!
ReplyDeleteLove love the fact you put video. I was going to record it but thought it would be a pain. I listened to yours and it reminded me some things she said. I slso thought that the fungi digesting the trees part was interesting to learn the different parts of the tree and their function.
ReplyDeleteAlso thank ou fpr adding this information "growth type of this lichen is "foliose" out of all two other types of growth including fruticose and crustose. It is foliose because the lichen fungi in Figure 1. seems to show leaf-like structures that loosely attach to the substrate." With my own research I learned that
Fruticose lichens are the most 3D. Their cross section is round (terete), and most are branched. They can be like little shrubs growing upward, or they can hang down in long strands.
Foliose lichens are somewhat leaf-like,made of lobes. They are relatively loosely attached to their substrates, usually by means of rhizines. Their lobes have upper and lower sides and usually grow parallel to the substrate. Umbilicate lichens are attached to their substrate only at a central point.
Crustose lichens form crusts that are so tightly attached to the rocks, trees, sidewalks, or soils they grow on that they can't be removed without damaging the substrate.Crustose lichens that grow immersed in rocks with only their fruiting bodies above the surface are called endolithic, and those that grow immersed in plant tissues are called endophloidic or endophloidal. Loose, powdery lichen crusts without a layered structure are called leprose.
Overall nice post!
