My Muddiest Point!

What is a polar nuclei and what is its function in a plant?

Muddiest point. :/

What are the difference between vascular and non vascular plants?

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!

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.

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

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

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:

1. upper & lower epidermis- protect everything inside the leaf and prevent tearing
2. cuticle (cutin)- prevents water loss
3. spongy mesophyll/palisade mesophyll- photosynthesis
4. stomate- gas exchange (takes carbon dioxide in, releases oxygen) & releases water (transpiration)
5. vascular tissues (vein)- tranportation

**TONIGHTS HOMEWORK IS UP 67&68**

**8.2 & 8.3 ARE DUE FRIDAY WITH UP 81-85 OR CORNELL NOTES**
