Hey Guys!
I'm still a little confused on the function of the spongy layer. I always forget that one for some reason. If anyone has a trick to remember it can they share it with me? Thanks

Hey guys! So I'm kind of confused on the process of double fertilization, so if someone could explain this to me, it would be great. Thanks!

Hi Guys!
Today in class we reviewed all of our labs before taking the lab quiz. Everyone had some great questions and that helped me greatly on the quiz. Next we took the plant quiz. For the quiz we wrote down our answers from thee questions that were projected on the board. After everyone was done with the quiz we covered pollination and took notes on it.

Here are some key points to remember about pollination:

>Their are many types of pollination consisting of self pollination, cross pollination, wind pollination, and vector pollination

>Self pollination-Very efficient, fertilizes the same plant.
>Cross pollination-Efficient,fertilizes another plant.
>Wind pollination-Not efficient, needs high production of pollen.
>Vector pollination-More efficient than wind pollination, produces less pollen.

We also learned the three steps of fertilization:
1. Pollen lands on stigma.
2. Pollen tube grows into the style.
3. Sperm and egg unite forming a zygote

Hw-FINISH PROJECT!!!
Study for pod quiz and unit test
Finish all the reading from up3 by test time

how does the fruit function in a plant?

hey guys!

I'm a little confused on what a cortex does in a root? If someone could explain the function for me that would be great!

Muddiest Point

Hey guys!

I'm confused on what exactly the polar nuclei are and also all of the reflecting and absorbing stuff with the chlorophyll and other colors

If you could help that'd be great!!!

Muddiest Point

Hi guys!

The only thing I am confused on is how to tell if something is a stem or a root.

If someone could tell me that would be great!

Muddiest Point

Hey guys! So i am having trouble remembering what the cortex and the polar nuclei is? if you have any idea on how to remember them that would be great!

Thanks!

Muddiest Point!

I was wondering what the 4 defining characteristics of the plant kingdom are and how do you identify which parts of the plant are edible. Thanks!

Muddiest Points!

Hi guys!

I always get confused with xylem and phloem. I know their functions, but I get confused which function goes with which. Is there any good way to remember them?

Also, what is the function of a receptacle?

Thanks! :D

Hi guys, I am a little confused on the function of the stamen and the pistil. If someone could help me, that would be great!

Muddiest Point

Hey guys. I'm a little confused on the differences between a dicot and a monocot. If you could help me with that that'd be great! Thanks!

Muddiest Point

I am a little confused on the difference between the stoma and the stroma. Also, what evolved first out of the following: mosses, ferns, gymnosperms, and angiosperms?

Muddiest Point!!!

Hey everyone!

I'm a little confused on the functions of the sepal and the petal.

If someone could help that'd be great. Thanks!

LAB QUIZ TOMORROW

POD quiz thursday

POD Quiz:

-what they look like

-key characteristics

-*tip: If a word is bolded then you should know it, and then be able to give examples*

Transperation:

Water Pulls Up- through Vascular Tube

UP AND OUT!

- constant pull of water to get more water

ROOTS

Some definitions we went over:

Vascular: Transport tissue

-through Xylem water goes upward

-through phloem food(sugars) goes everywhere

Cortex: Food Storage

Root Hairs- increase surface area

-absorbs more h20

STEMS: no vascular cylinder

Muddiest Point!

Hey Everyone,

What does a vascular cylinder do? Also, how does a chlorophyll molecule absorb and reflect different wavelengths of light on a visible spectrum?

Thanks,

Sonya A.
