muddiest point

my muddiest point is where does the electrons come from between light independent and dependent cycles

Muddiest Point

where do the electrons come from in the photosynthesis process, and where do they go/what do they do?

Muddiest Point

My muddiest point is can a gymnosperm have flowers?

Muddiest Point

Can you please tell me what the role of ATP and electron carriers (NADP+) are in photosynthesis?

muddiest point

My muddiest point is telling the diference between a monocot and a dicot plant. what are the main diferences?

Muddiest Point

My muddiest point for this unit is on capillary action. I am confused on what it is.

Thanks

Muddiest Point 3/20

My muddiest point for this unit is number 9 on the objectives page. It says, understand life cycle of angiosperms including the process of double fertilization and seed formation. (pollen tube, polar nuclei, ovule, endosperm). I know that angiosperms are plants that flower, but I am confused on this whole idea.

3/20 SCRIBE

Today in class we took our lab quiz. After that, we discussed Pollination (Self and Cross). Self pollination occurs when the anthers of the flower are taller than the stigma. The pollen falls onto the stigma and creates a long tube to the ovary. Cross pollination is when wind or some other factors carry one plant's pollen to another plant's stigma. Homework: National Parks projected submitted to Mrs. Stein by 7:30, Read 24.2, Muddiest Point, Comments by Thursday, POD quiz Thursday, Test Friday, and Readings on UP 3.

The next Scribe will be: PeterS

JoeM's Muddiest point

My muddiest point is how to tell what is a stem and what is a root.

SCRIBE 3/19

In class on 3/19/12, we reviewed cellular respiration in a cell, as well as transpiration and perspiration. We also worked on UP 41-44 towards the end of class. We went over the differences and similarities between roots and stems, such as the Vascular Cylinder.We also went over the differences between monocots and dicots. The homework was to finish UP 41-44, study for the quiz, finish up our National Parks projects, and study for the test on Friday! The next scribe will be Joey!

GabbyM's Muddiest Point

What is the function of a cortex in a root? Also, what is the function of a vascular cylinder? I know that if there is a vascular cylinder, it is a root, but I don't know the function of it.

Muddiest Point

My mussiest point is telling the difference between a moncot and dicot root. How can you tell the difference between the two?

My muddiest point

My muddiest point in this unit is the importance of pollination, and seed dispersal

Scribe post 3/13/12

Today in class we started a lab on pages up 25-32 with the fruit sheet we got in class. We will be working on this lab tomorrow and it will be due on friday. our other homework was to read chapter 23.2 and to skim chapter 23.3 in the text book. Mrs. stein said that these readings are to be used as a reference this week for our lab and our objective. There will also be a quiz next tuesday on our leaf lab, the lab on pages 25-32, and on a flower lab we are going to do.

The national parks project is due next wednesday

3/12/2012

Today in Mrs. Stein's class we received graded work. Mrs.Stein went over the piment lab the went over what we were doing with the data analysis(up 73-76). We also reviewed photosythisis for tommorow's quiz.

Scribe of 3/8/12

Today in class-
1. First thing we did was get stamps on our homework which was UP 67+68
2. Next we started a CHROMATOGRAPHY LAB!
3. Lastly we talked about photosynthesis

In class today we did a Chromatography lab (UP 69-72). The goal was to try and find what pigments can be found in the different colored leaves. These are the pigments we saw instantly in the spinach leaf.

And after we let it sit in rubbing alcohol, it looked like this. These were are all the pigments that we were able to find in this leaf.

Are Homework for tonight is:

1. Research for your group projects

2. Finish the Chromatography Lab (UP 69-72)

3. UP 81-85 with section 8.2 and 8.3 (or you can do cornell notes)

TOMORROWS SCRIBE WILL BE ___________?

Class on March 7th, 2012

Today in class, we discussed photosynthesis, the structures that make up a leaf and their functions, and energy.

The plant of the day were "Living Stones" or Lithops lesleie

-Succulent - plant which had the ability to store water

-Two fused leaves with few stomata, modified to prevent evaporation

-Mimics the color and appearence of rocks-less obvious to foraging animals

-Produces yellow or white flowers

-Native to South Africa and Nambia

Plant structure were reviewed, key structures include...

-Upper Epidermis

-Vascular Tissue (water transport tissue)

-Spongy Mesophyll (cells are loosely packed to allow easy gas exchange!)

-Cuticle

-Palisade Mesophyll

-Stoma

-Guard Cells

-Lower Epidermis

We discussed energy, specifically the questions on page 61 of the unit packet.

Homework:

-UP 67-68 (Due Tomorrow)

-READ 8.2 and 8.3 with... (Due Friday)

+UP 81-85

OR

+at least 2 pages of well-done cornell notes

Class on 2/24 and 2/25

Today in class we looked over the two plants of the day. The first one we looked over was the VENUS FLY TRAP. The second one we looked over was the BASEBALL PLANT.

We went over the 4 characteristics of the plant kingdom.

1. Eukaryotic

2. Photosynthesis, autotrophic, and contains chloroplasts.
3. Cell wall with cellulose2. Photosynthesis, autotrophic, and contains chloroplasts.

4. Multicellular

We also talked about the phylogenetic tree. The Green Algae and the Mosses have to live in moist environments due to the fact that they do not contain true - water conducting tissues.

We also went over our quiz.

Things plants need to survive.

1. CO2 for photosynthesis.

2. water for photosynthesis.

3. sunlight (energy)

4. minerals (nitrogen)

5. O2 for cellular respiration!

- Plant's mitochondria get glucose from photosynthesis.

Challenges for plants moving from water to land.

1. The ability to obtain water some way.

2. Prevent from dying due to direct sunlight

3. REPRODUCTION
