i think we might be obversing a layer of the leaf that would be hard to see without using this sort of lab. i've done research and i think that the round carters are seed leaves inside the seed coat. They usually contain the endosperm to feed the embryo plant.

I believe the craters are the stomata or pores in the leaf. It was interesting how the dicot looked like broken glass under the microscope. I also find it interesting how the monocot looked like wood panneling.

They open and close to let out water/gas vapors. And I believe that they are a part of moving water around because it releases water to adjust pressure inside the plant.

The stomata interacts with the xylem in carrying water throughout the plant

The stomata opens and closes allowing carbon dioxide to enter while water and oxygen exit. It allows water into the plant.

In my slide there were serveral craters which Mr.Delsol described as "lips." I believe they are the stomata. It looked very similar to a shattered phone screen.

I think the mallow imprint looked a lot like the moon because of all of the diofferent pores, or craters, that were visible. These pores are probably the holes left by the stomata. The nile lilly plant had pores as well but these went in a verticle direcion. I think that that is the imprint of the xylem going through the leaf and transporting water.

The pores really seem that they help with sucking in the water to help the plant receive that water through out itself. My guess is that those pores are the stomata.

the pressure is controlled by the little craters (you described them as lips) whem they open they are sucking in air and when they are more close they are preventing air from going inside.

What allows plants to perform transpiration is the stomata, when they are open and moving air out it is like sucking on a straw, when they are closed it is like putting your thumb over the top of the straw to keep the water from moving, and when they are pulling air in it is like blowing into a straw forcing liquid down.

Trees take water up the plant through the xylem and takes the sugars and nurtiends back down and distributes it through the phloem. They use atmospheric pressure to help with this movement. The atmospheric pressure also affects the rate of transpiration; the more atmospheric pressure on a plat, the less the rate of transpiration will be, and the less pressure, teh higher the rate will be.

The craters and pores that are seen in the slides are the stomata, which kind of look like lips, and they are the structures that control gas exchange in the leaves. I think the stomata help with the transpiration and moving water throughout the plant because the stomata control the air flow which affects and controls the pressure. This pressure affects the levels of transpiration in the plants.

In my opinion I believe that the plant is getting used or adapting to the random pressure. This causes the water to go in and flow through the plant via the stomata with the help of guard cells; letting how much water goes in the plant using pressure change.

As the water passses through the stomata, it allows little amounts of the water to bypass to even out the pressure that is given out from the fan. The fan represents the wind as if the plant was outside in the elements. The reasoning of how tall plants, such as trees, can trasport so much water to the peek of the plant is because th cells help transport water up. When the wind picks up, little amounts of water are left behind to help the rest of the water finish its journey up to the top. The guard cellls also help by keeping a lot of the water in the plants by staying close like a door to a classroom.

When the pressure decreased in the first five minutes of the lab that might have been the plant pulling water in, the next five minutes were probably the plant moving the now nutrient rich water back down to other parts of the plant.

The higher the pressure is in the plant, then there is less water leaving the plant. Lower pressure means more water leaving the plant. With wind blowing on the plant, it needs more water to compensate for dehydration, meaning a decrease in plant pressure. The stomata are what allow transpiration to occur because they open and close, controlling the air flow. The guard cells are what control the opening and closing of the stomata. The stomata are pulling in air like sucking on a straw, creating pressure at the roots to carry water up through the plant to the leaves.

They use atmospheric pressure to move water inside the plant. It also affects the rate of transpiration the more atmospheric pressure the plant has the less rate of transpiration there will be, and the less pressure. The xylem moves water and other sugars and nutrients up and down, the phloem then distributes it. Also i think the crater are the stomata.

the higher pressure you have the less water that the plant is going to take. When the pressure is low the plant is going to take more water. when the wind hit the plant it takes more water, because the plant gets dehydrated and the pressure goes down. the stomata are what allow transpiration to occur because it opens and closes. guard cells helthe stomata open and close stoping the air floe in the plant.

The water enters the plant through the guard cells and then travels through the stomata, creating pressure which then sucks in the water, like when you drink through a straw.
