Ethylene promotes the fall of leaves by triggering the death of cells and abscission. What region of the leaf responds to ethylene?
a. the lamina, where photosynthesis takes place
b. the vein, which carries nutrients and water in and out of the leaf
c. the petiole, which attaches the leaf to the stem
d. the margin, which is serrated and may be sharp

A pickle dominance is the concept that implant structures the inner support grows much stronger than the branches or the outer pointing points, which is shown here by my rough draft of a tree, and this is due to the hormones that released the oxygen's.

Question number 19 in regards to plant biology asks us to choose the correct term below, and it is looking for something that enhances a pickle dominance. Now, typical dominance to begin with is the tendency off plants to grow from their apex rather than laterally. So what do you mean by Apex? Is the tip basically and any lateral growth would occur along the side of the planet. All right, so in order difficult is that we're gonna go over each of these five hormones Options, Jabbar, Elena's absence, it acid, ethylene and side of kindness. This 1st 1 ox ends, it's going to cost two things. It's produced in the a fix of the plant and travels down. It's going to cause the plant to bend toward sunlight, and it also inhibits lateral growth. So if you're paying any attention at all, you know that this is the correct answer to the question. Uh, but to be thorough, we're gonna continue going over the rest of these hormones because they're all pretty important. This next hormone called Deborah Ellen. It's a pretty important in germination, and it also regulates intern nodal length, So that's basically the length between new growth or, in some plants, just the leaves. In general abscess IC acid is important because it, uh, kind of notice eyes the plant that it's dehydrated. In order for plants to move water against gravity. They rely on evaporation out of the bottom of leaves. And what Epps is sick acid does is it causes the plant to close up the holes on the bottom of the leaves called Stella, and that prevents extra loss of water. Next hormone ethylene Uh, this is given off by ripening fruit and calls us for to ripen. So if you are an apple tree in an orchard and your next door neighbor, apple tree, is going to start ripening its fruit, it's beneficial for you to wrap in your fruit as well, eh? So that any animals that come to consume the fruit of your neighbor also consumed your fruit. More babies is good and evolution, and so that is a beneficial thing for plants that are near one another to ripen at similar times. And the last hormone is called side of kind in any kind of counters. The things that accent does, uh, it. While accident tells the plant to grow from the tip a side of kind and tells the plant to grow from the ground. So whether that means making longer routes or making new shoots. So like I mentioned earlier, we can pretty easily conclude that options are the correct answer. However, it is good to be thorough and make sure you're familiar with all the aspects of a question if you're going into any kind of stand bys, test setting or if you just want to be alone, grounded scientists.

So the question here asked us the difference about the difference between a mono kat so a mono caught and a die caught plant. So let's go through the differences here. So Monaco indicating that it has one cattle Eden. Um, their veins air usually parallel. It has vascular bundles that are complex, unusually complexly arranged. They have fibers, root systems, and they have four parts, which are going to be in multiple of threes. Whereas die cots again die meeting to. We have to coddle Eden's. Um the veins are usually met like vascular bundles are arranging a ring, and tap roots are usually present. And thief Laura parts are gonna be in multiples of either four or five here. So the question here asked. Unlike you die cots Monica's lack What? So Monica, it's, um, for a here it says vascular bundles. So again, both of them are gonna have vascular bundles. So this cannot be a correct answer for be here. It says, um, parent Chema. So if you recall your parent, kema is essentially the functional tissue, Um, that is soft found in the software parts of the leaves here. So essentially, these are gonna be the floral parts. So both of these, we're gonna have it. So this cannot be it, Um, for see here. It says it's gonna have a pith. So again, a pith is going to be a spongy white tissue. Um, that is going to essentially line the rim oven orange, which essentially branches, um, into a higher essentially forms a plan, a branch, in other words. So again, in die cots, we're going tohave the taverns here. And this is going to be the difference here where, um, dich odds are gonna have a pith, whereas Monaco Hot Stone. So this indicates that d here can be incorrect due to the fact that epidermis is are found in both on the outer layer of the cells. So thes are going to be the correct. This is gonna be the only correct statement here where Monica do not have, um, Pieth

When we look at Palisade and spongy parent Kema, they're usually found in the mess Phil of you tickets. Since you two cots have vascular tissue and palisade and spongy parent heimer our tissues found on the upper and lower part of the leaf.
