A person observes that some plants have deep red, violet, and brown colored leaves. Can these leaves carry out photosynthesis? Give reasons for your answer. What is the first statement in this video.

• You see this, there's a whole handful of leaves, off the trees here, on this beautiful fall day.

• If you notice; well some of them are red, some of them are

  yellow, some of them are brown. The leaves are changing this time of year. Today's episode is all about why that happens?

• So. I'm here today at the Nature Research Center to learn about why leaves change color and to know maybe how that happens.

• We're here; it can't be Meg. it's Meg Lowman; canopy Meg. My nickname is canopy Meg because I love leaves. I go around the world and climb into trees to look at leaves.

• Meg began by giving me a very general overview of a typical leaf.

A person observes that some plants have deep red, violet, and brown colored leaves. Can these leaves carry out photosynthesis? Give reasons for your answer. What is the second statement in this video.

• You see, within every leaf are plant cells that contain within them special organelles that convert light into energy called chloroplasts. Within chloroplasts or different plant pigments

  that absorb different wavelengths of light.

• You see, within every leaf are plant cells that contain within them special organelles that convert light into energy called chloroplasts. Within chloroplasts or different plant pigments

  that absorb different wavelengths of light.

• Most of those are the green chlorophyll, but there are also other pigments like the orange or yellowish carotenoids.

A person observes that some plants have deep red, violet, and brown colored leaves. Can these leaves carry out photosynthesis? Give reasons for your answer. What is the fourth statement in this video?

• You see, within every leaf are plant cells that contain within them special organelles that convert light into energy called chloroplasts. Within chloroplasts or different plant pigments

  that absorb different wavelengths of light.

• Most of those are the green chlorophyll, but there are also other pigments like the orange or yellowish carotenoids.

• Under the chlorophyll has always been these other colors of pigment. So, when that chlorophyll is sensitive to the cold and starts to die back we see those yellow colors. it's really really

  beautiful. So that is the basic gist of color change and of course, that explanation works well.

• You see the green right next to the yellow here and you might think what happened, but the yellow is always there and that is easy to understand.

• You see the green right next to the yellow here and you might think what happened, but the yellow is always there and that is easy to understand. It makes sense.

• But, we haven't talked about the Reds. Take this leaf for instance, notice how it's already turned yellow and if the fringes ,t's starting to turn red

  
  

A person observes that some plants have deep red, violet, and brown colored leaves. Can these leaves carry out photosynthesis? Give reasons for your answer. What is the seventh statement in this video?

• The red generally comes from pigments called anthocyanins. The trick is that those pigments aren't in the leaves most of the year they're produced in the fall.

• Most of those are the green chlorophyll, but there are also other pigments like the orange or yellowish carotenoids.

• Under the chlorophyll has always been these other colors of pigment. So, when that chlorophyll is sensitive to the cold and starts to die back we see those yellow colors. it's really really

• The red generally comes from pigments called anthocyanins. The trick is that those pigments aren't in the leaves most of the year they're produced in the fall.

• That's why you see those red pigments creeping in towards the middle of the leaf. But to really understand the

  red let's get into the chemistry now.

• The red generally comes from pigments called anthocyanins. The trick is that those pigments aren't in the leaves most of the year they're produced in the fall.

• That's why you see those red pigments creeping in towards the middle of the leaf. But to really understand the

  red let's get into the chemistry now.

• Anthocyanins are produced when sugars combined with compounds called anthocyanins because anthocyanins needs

  sugar for their creation.

• The red generally comes from pigments called anthocyanins. The trick is that those pigments aren't in the leaves most of the year they're produced in the fall.

• That's why you see those red pigments creeping in towards the middle of the leaf. But to really understand the

  red let's get into the chemistry now.

• Anthocyanins are produced when sugars combined with compounds called anthocyanins because anthocyanins needs

  sugar for their creation.

• Weather conditions that favor sugar production that's photosynthesis are essential and that means that bright sunny fall days produce the best colors
