Lichens are not one, but two organisms, a partnership of two kingdoms. Lichen is made of a fungus (usually ascomycete) and an alga (gray or green).
There are 20,000 kinds of lichen, each with a different variety of fungus. There are fewer algae in many lichens; so fewer algae are involved.
A lichen body is made of sturdy fungus hyphae, and the alga is sheltered within. The fungus provides the alga with water and mineral nutrients; the alga in turn leaks out nutrients, which is absorbed by the fungus.
This partnership is so tough that lichen can live where no other creature can live. If the weather turns too hot, cold, or dry, the lichen goes into a state of suspended animation until the environment is desirable.
Because lichens are only 5% algae, and because the alga grows very slowly, lichen grow only about 5 mm a year. Therefore lichen live for centuries, or in a few cases, millennia.
Lichens only weakness is that in getting nutrients from rain in polluted areas where sulphur dioxide is dissolved into the rain, lichen absorbs the poison and often dies as a result.
This is a perfect example of symbiotic relationship.
It was a gorgeous Saturday afternoon. Maria was teasing Landon with the phone. “I am going to dial 911, Landon. I am going to call the police.” Landon grabbed the phone from her, and someway or another the button to call was pushed, then the button to hang up.
Ring-a-ling-a-ling! My dad answered. “Hello… No it must have been one of the kids… That’s fine… OK, sorry about that… Bye.” Turning around to Landon and I he said, “That was the police! They’re coming over here to make sure we are all right.”
When the Police car finally pulled up, Maria was nowhere to be seen. The policeman who came to the doors name was Officer Bill. “So, who was on the phone?” he asked promptly. “I think she is hiding.” my Dad replied. “I will go down and try to dig her out.” Dad did not succeed in getting her out. So Of. Bill came downstairs to Maria, who was crying hysterically. Despite all persuasions, Maria would not come out from the covers of her bed. Eventually we returned upstairs, where Of. Bill gave John Paul, whom the officer had named “his buddy,” stickers for himself, Alex (who was at the docter,) and Maria.
Five minutes after Of. Bill departed, Landon and John Paul were patroling the basement with belts on, toy guns in their belts, and their junior officer stickers on their shirts, pretending to be policemen.
This is the true account of our 911 episode.
Days on which there is nothing to write, I will post compositions and other things I have written. I wote this to use in a science fair project, which won first place. There are other things about fungus I have written, check back later to read them.
When one thinks of fungi, one’s first impression is probably bad. One may think of mildewy shower curtain, moldy food, or a rotting house. But not all fungi are bad. For example: fungi play an important part in decomposing, medicine, and food. With this in mind, let’s take a closer look at fungi.
Humans have put many fungi to work for us; others naturally are helpful. Yeasts, which when feeding give off carbon dioxide and ethanol, are put in dough or juice and these gases are trapped, resulting in fermentation. Further, farmers spray parasite spores on fields to exterminate insects. We utilize mould to ferment soy sauce, give flavor to cheese, and save lives by exercising moulds ability to eat harmful bacteria such as typhoid. Moreover, without symbiotic fungi, which reach out with their hyphae to find nutrients to bring a plant friend, there could not be forests of trees, or some plants. Above all, without fungi to decompose organic matter, we would be buried in carcasses!
But there’s also a bad side to fungus. Mushrooms appear in otherwise perfect lawns. It rots our crops, food and houses. Also, there’s natural yeast in us all, and if this gets too plentiful it causes a candida infection. Poisonous toadstools cause a number of deaths each year. Parasites can be an annoyance, others kill the host altogether; Dutch elm disease destroys forests of elm trees all over the world!
In conclusion, fungus is essential in many different ways. It also can be a nuisance. But maybe the next time you see fungi on your lunch, you will give a thought to its importance before throwing it away.
My Valentines Day was spent holding Joseph, (who is sick, and running an almost 102 temp) and wiping Alexanders nose (you may have already guessed that he is sick also, with the same temp.) There was a party today, but because of obvious reasons we had to stay home. The last five days we have done little or no school (we homeschool) and have spent most of the time watching the sick ones. So much for having a good full week of school. Happy Saint Valentines Day!
I am a Catholic of 11 years. I enjoy knitting, ballet, cross stitching, spelling bees, quiz bowls, science fairs, geo bees, cooking, classical music, reading, gardening, raising caterpillars, and caring for Joseph and Alex. The von Trapp children and Steve Green are my favorite singers. My birthday is March 13. Some of my favorite movies/TV shows are The Sound of Music, The Wizard of Oz, Bewitched, Bernadette, Knight Rider, and I Dream of Jeanne. Some favorite books of mine are Island of the Blue Dolphins, the Julie of the Wolves series, and the Narnia series.
I was baptized April 30th, 1995, went to First Confession April 27th, received First Holy Communion April 28th, 2002, and was confirmed April 23th, 2006.
Pictures coming soon!
My mom caught Joseph with a musical toy of his on, and he was bouncing his middle around! Major milestone! I love babies. :)
Alex will be 3 April 4th, his favorite song/book is Baby Beluga, and he enjoys sucking his 3rd and 4th fingers, picking the folds in his clothing, (or my folds, if I am wearing a dress,) trains, ‘taking care of’ Joseph, ‘helping’ and giving kisses.
It gives me great pleasure and amusement watching Alex and Joseph playing together. Alex will come up to the crib after Josephs nap and says ” Hu-wo (hello), ba-by” in a soft, drawn out voice. If Joseph touches Alex, Alex says with great delight “Mama(or name of person nearest to him,) (pointing) baby!” If Joseph sticks his hand in his mouth Alex says “Mama (or name of person nearest to him,) (sticking his own hand in his own mouth and pointing to Joseph)”
Alex and Joseph are my own boys and I love them.
Getting older has many rewards in our homeschool group. One of such rewards is the Quiz Bowl. This is how you play: the captain of a team picks a number of a unknown question (last night there were 30 questions in a round) and the reader reads that question out loud. The team that picked the question talks among themselves as to what the answer is (they have fifteen seconds to do this) then the captain gives the answer he thinks is right. If the first team gets the answer wrong the opponent team gets ten seconds to think it over then give their answer. If niether answers are correct, the reader announces the correct answer and the game continues. Last night was my second Quiz Bowl, and my first time being captain. Results are as follows:
Round 1. Sioux Falls/Brandon Valley: (My team) 6 points Opponent:11p. Winner gets 5 points = 16 points
Round 2. SF/BV 12+5=17 points Opponent:7 points
Round 3 SF/BV 6 points Opponent: 19+5=24
Round 4 SF/BV 11+5=16 points Opponent:8 points
Round 5 SF/BV 9 points Opponent: 13+5=18
Round 6 SF/BV 7 points Opponent: 17+5=22
The team of which I was captain came in 18th place out of 24 teams
John Paul thinks he is superman. He is five years old and his B-day is Aug. 30. He enjoys legos and duplos, playing in the dirt, video games, television, trains,
Macaroni & Cheese is John Pauls favorite food. His favorite color is orange (or blue, he doesn’t know which.) Star Wars, (he has seen 4, 5, and 6,) Larry-Boy, and Superman are his favorite movies.
Snapdragons are Maria’s favorite flowers. She is seven and her birthday is August 27. She enjoys having friends over, board games, video games, computer games, dressing up, gardening, watching TV, and washing mirrors, and scrubbing floors. Her favorite animals are cats, although she likes horses.
Maria won first place for a kindergarten to third grade division of a science fair . Her presentation was on the water cycle. She had a very pretty board and in my opinion did a good job. Apparently the judges thought so also.
Joseph is my Godson and the largest baby in the family. He reached the weight I was at one year at 6 mo! He was born on June 26, and is seven mo. old. He enjoys pat- a- cake, playing with his siblings, playing with large buttons, playing his toy piano, and eating toilet paper (although a kleenex will suffice.)
Joseph has an exquisite taste for leather jackets, literally. Starting to become very mobile and adventurous, we really have to keep our eyes on him, for he will eat (or try to eat) anything he may find!
Every baby in the family including myself has looked exactly like my father when he was little. Joseph has a full head of bronze hair and a smile that can make you say: aawwww.
Joseph is a perfect little baby brother and my family loves him.
I have been excited for a blog ever since my Dad mentioned about making one for me a year ago.
We both forgot about it until Wednesday, when I thought about surprising him with making one myself, (with Mom’s permission of course,) but alas, I found out I could not use the provider I wanted until I was thirteen. It was time for my Dads help. He helped me, so here I am, here is my blog, and here I am writing my first post. As a blogger I shall faithfully try to answer all comments. I may be awkward at first so bear with me. Goodnight
