muddy point
The only thing I don't get is what the polar nuclei is and it would be cool if you could help.
Muddiest point!
Hey guys! Heidi, here. I was wondering what gymnosperms are and what the stoma or stomata or whatever its called does and what they are. HELP!!
My Muddiest Point!
What is a polar nuclei and what is its function in a plant?
Muddiest point
I dont understand the differences between all the types of plants.
point that's mudddddy
My muddiest point is........what's a granum again?
Muddiest point. :/
What are the difference between vascular and non vascular plants?
Muddy point!!
Hey yall so what is the roll of root hairs what do they do???

PITTY!!
also ive been having a super hard time with this blog and getting posts up. i know im missing a muddiest point somewhere so i thought id try to make it up with some of my cool plant facts!!
- a gash in a tree will stay the same distance from the ground as it grows taller
- almost 200,000 pencils can be made from an average sized tree
- one tree makes about 260 pounds of oxygen annually, which is enough to supply for a family of 4
Muddiest Point :(
sooo my muddiest point is the difference between ANGIOSPERMS and GYMNOSPERMS
point thats muddy, lets clean it upp
ok what is angiosperm?? is there anything that goes with it or types or something im so confused.
thanks :)
muddiest point!
hi so my mudiest point is what is the importance of cross vs. self pollenation. Thanks!
Muddy Point
Hey! It's Kara S. I really don't understand polar nuclei and the functions of the parts of a flower!
Muddiest Point
Hi guys, it's Eunice L.
For my muddiest point, I'm confused about what the function of root hairs are. How do they help the root?

A Point thats Muddy
Hey, its Mark I'm still a bit confused on what surrounds the Xylem and the Phloem what is its exact name,and does it have a different name when in the root vs. the leaf or stem.

stuck in the mud.
hay guys it's TessaN. does anyone have a good way to remember the vascular bundles of monocots and dicots? Which one is spread out and which one has the bundles in a circle?
SCRIBE!
Hey guys! It's Tessa N heree. So today in class we found out that FRIDAY is Mrs. Steins last day! :'( but... we are gonna have a baby showerr party! So don't forgett to bring food... Haha anyways we started off by going over the plant of the day, the string of pearls, also known as senecio rowleyan. Then we continued to review transportation, roots, and monocots vs. dicots. Transportation is the process by which water moves up a plant and out of a leaf. We learned the structure of roots, such as the cortex, stores food. Monocots and dicots both have vascular bundles, however the way they are arranged is different. Monocots have parallel leaves, 1 cotyledon, multiples of three flowers, and have fibrous, multiple roots. Dicots have branched leaves, 2 cotyledon, multiples of four or five flowers, and have a taproot, or a big main root. We then ended class by working on our flower labs for the last 15 minutes.
My Muddiest Point
Hey guys, it's Maggie! My muddiest point this unit is what the functions of the xylem and phloem are. Thank you!
muddy chlorphyll
My muddiest point is the balanced equation for photosynthesis how do you do it.
Muddiest Point
Hey its catie here! my muddiest point is this: im still confused by the whole pigment thing...i know chlorophyll is nessecary for photosynthesis...but how does it 'absorb' other pigments? help please!
MUDDIE POINTTTT
my muddie point for this unit is the life cycle of angiosperms
Muddy point!!! Unit 9: Attack of the weird plants @_@
My muddy point from this unit 9 was, how does a chlorophyll molecule absorb and reflect different wavelengths of light on the visible spectrum??
Someone help me!!

SCRRIBBEEE!
Hey guys!
SO, yesterday we learned about the SPIDER PLANT. Pretty much looks like a normal green plant, but with little spidery-looking things at the end of the leaf. After that, we review a tiny bit before our photosynthesis and leaf quiz! yay. quizzes. Once we finished that up, we started a lab that dealt with the investigation of plants! Some things like tropisms and monocots and dicots, which we will continue to do on Wednesday and thursday. So yeah thats pretty much it, peace out. Have a lovely rest of the week everyone! :)

Scribe of the day
Hey y'all its catie here!
In class today, we...
-Discussed our pigment labs
-got grade reports
-began the lab on UP 73-76
-& discussed photsynthesis.
We spent a lot of time talking about photosynthesis. REMEMBER, WE HAVE A QUIZ ON IT TOMORROW!
Here's the scoop on photosynthesis:
-It all happens in the CHLORPLAST
-The STROMA is the name for the open space of the chloroplast
-The GRANUM is the 'stack of pancakes'. This is where the Light-Dependant reactions occur
-The 'pancakes' are called Phlatoids, and contain chlorophyll (which is the pigment nessecary to undergo phtosynthesis!
-The 'pancakes' also contain electrons
LIGHT-DEPENDANT reactions:
-Light comes in and hits the electrons, which gets them excited! Their energy level shoots up
-This splits the H20 molecules (which releases oxygen)
-Then, the electrons loose energy to form ATP
-The now split (or lonely) H+ molecule and NADP forms NADPH
-This carries nessecary energy to the CALVIN CYCLE
LIGHT-INDEPENDENT reactions: (a.k.a Calvin cycle)
-C02 is added to a 5 carbon sugar
-Engery from NADPH and ATP are used to carry out reactions
-Produces sugars (glucose!)
-DO NOT call this the 'dark cycle'! BECAUSE IT DOESN'T have to happen in the dark! This cycle doesn't care if its dark or light, it will still happen the same
OKAY BYE

Hey guys! Heidi, here!
Today in class Mrs. Stein talked about photosynthesis and how we will get into
detail about it tomorrow. We also did a LAB where we had to put its pigment on a
piece of paper and soak it in a certain CHEMICAL. We then took a break and then
we went over the HOMEWORK and after we were done with that we went to check
on our PIGMENTS!!!
If you don't know the homework. ..........SHAME on YOU! but...its to finish the lab (UP 69-72) and to do (if not done already) UP 81-85 or corrnell notes on 8.2 & 8.3
NOW we all know we learned about Moss Balls! & how COOL they are!
SO....... I found a couple videos that show what Moss Balls do!
BUTT! Since my computer doesn't let me do anything for the blog....I'm leaving the link! SO TAKE A LOOKSEE!
Video #1:
Video #2:
video i found about pink wavelengths
I found this video online and its kind of related to what we're learning about with wavelengths, and it shows that there actually isn't any pink light.

SCRIBE--MARCH 7
HEY EVERYONE!! kelly here with the scribe post
so today in class...
- Mrs. Stein stamped our homework homework from last night which was UP 79&80.
- then we talked about the PLANT OF THE DAY which was living stones which are plants that look like rocks so that other animals won't eat them
- we also answered the question on page 61 in the unit packet which was about energy
- later we reviewed the functions of the structures in leaves:
- upper & lower epidermis- protect everything inside the leaf and prevent tearing
- cuticle (cutin)- prevents water loss
- spongy mesophyll/palisade mesophyll- photosynthesis
- stomate- gas exchange (takes carbon dioxide in, releases oxygen) & releases water (transpiration)
- vascular tissues (vein)- tranportation
**TONIGHTS HOMEWORK IS UP 67&68**
**8.2 & 8.3 ARE DUE FRIDAY WITH UP 81-85 OR CORNELL NOTES**

SCRIBEEEE
Hello people of 8th period biology! Sooo yesterday we started class with our last two commercial presentations (which were awesome!!!!!!). Then we went to our POD which were a baseball plant, and a venus fly trap. The baseball plant is very interesting because well it looks like a baseball! It grows in the desert, it is the type of plants that absorbs water and stores it (like a juicy steak). The venus fly trap is very cool, it makes a sweet lining of nectar to attract flys. When the fies come over and start eating the nectar the venus fly trap have six hairs, if two are touched with in twenty seconds of the fly landing on it, it automatically closes. After that we took a quiz on our plant reading. Then, we talked about our presentation project!
