"That's Plant Sperm!"

Hey guys!

We started off the biology class today by turning in our homework which was to read 24.1and do page 39 in the UP (which counted as a stamp) and the virtual transpiration lab which was pages 33-34B in the UP (we turned this in).

After this, as a class we got to ask Mrs. Stein questions about the lab and some kids were having confusion about homeostasis and the surface area of a plant's leaves. The surface area of a plant's leaves has to do with the stomata and how much transpiration will occur in the leaf.

We then went on to do a lab where we had to "dissect" a daffodil. This lab can be found in your unit packet pages 41 through 44. We had to locate multiple structures of the flower and we also had to cut open the ovary of the flower and locate the ovules, which are the structures in the ovaries that hold the flowers' seeds. The ovary is a female part of the flower.

We spent the class doing the lab with our lab groups and Mrs. Steinwent around the class assisting everyone when they had questions. We viewed pollen grains, or in other words--"plant sperm" under a microscope after dissecting that from the flower, as well.

All in all, the class was an interesting one. Let's keep in mind though that even though spring break is just around the corner, we have a busy week for bio!

Here's the following assignments:

1) Finish flower lab on UP pages 41-44: due tomorrow.

2) Lab quiz (a quiz on all of the labs we've done so far in this plant unit!): tomorrow.

3) Read 24.2 (pages 704-705) only, by Wednesday.

4) UP pages 45-46 dueWednesday.

5) National Parks project to be turned into Mrs. Stein by 8:00 AM on Wednesday morning!

6) Weird plants test (this is just a quiz/test on our eccentric plant of the days where we have to identify the plants, and then have 4-5 multiple choice questions on the information we've learned) on Thursday.

7) Plant test on Friday.

Good luck studying everyone!

Here are pictures from the flower lab we did in class:

The ovary of the flower split in half. The white "things" in the middle are the ovules--they contain the flower's seeds.

The materials/set up for the lab. From left to right: (top row): water for slides, slides, daffodils, (bottom row): razor blades, cover slips for slide, and hand lends for viewing during the lab.

Here is just a general idea of the lab.

Wednesday- Tuesday Big Lab!

WAKE UP WE'VE GOT MORE LAB TO DO!

So to start of here are just a couple of photos of just a few of the 9 lab stations. You have station 5's radish plant were we learned about how the sunlight effects the plants growth. In this case the plant will actually tilt itself towards the light. Also in station 5 there was the corn. The corn showed the effect of gravity on a plant and its roots. Roots alway grow down because of gravity so when looking an the sideways corn seeds all the roots are trying to go

Your next picture is of station 3. In station 3 we learned all about nonvascular plants like mosses. So we studied four different types of mosses as well as reading about nonvascular plants in the textbook. The next picture is of radish seeds in station 2. We put these under microscopes and viewed the tiny thin white hairs that came out from the root. We decided that the hairs were used for efficiently getting more water and nutrients by creating more surface area as well as helping the plant stay grounded. So there is a very small short overview of just a couple of the labs. And heres a review of what we (or what you should have) learn!

REVEIW

You should know.....

• how to identify the Zone of Elongation found in the Meristematic Zone
• What the difference between Vascular and Nonvascular plants
• ----------What each has and doesn't have
• How gravity effects plant growth
• How sunlight effects plant growth
• ----------Temperature and position
• Difference between Dicot and Monocot and how to identify them

Hopes this helps with the studying. The homework was just to finish the lab and 4 questions on the first two pages of 23.5

AND the next scribe is ....... JORDAN! Love you!

Hello.
This is Sam.

This Friday we finished up the lab for the majority of the period. Your groups are the same people that you worked with on the rip-o-meter lab. During the lab Mrs. Stein took students and tested them on how well they did when working with a microscope. Once the period is over we cleaned up after ourselves and left.
For if you didn't finish observations or was absent, here are the things we looked at:
Frog blood
Cheek Cells

Homework:

• Read 7.2 and Complete the Organelle Chart (Chart available on moodle)
• UP 9-14
• Extra Credit (click on "Extra Credit" tag)
