00:00Stay right where you are.
00:02It's Cyberchase for real.
00:05I'd give anything for a green thumb.
00:07No matter how hard I try, I kill every plant I own.
00:11It's a pattern, one that I need to break.
00:13You've heard of homicide?
00:15I'm guilty of hermicide!
00:19I water my plants every day.
00:21There's something wrong.
00:22I need help from an expert.
00:24It's OK, sweeties.
00:26We're going to get you some water.
00:33This is amazing!
00:35So many gorgeous plants, and none of them are dead!
00:41Can you help me?
00:42I have an emergency.
00:44Should I call an ambulance?
00:46Well, not that kind of emergency.
00:48I'm a plant killer, and I want to change.
00:52What do you mean?
00:53I mean, I want to learn more about plants so that they can live long and prosper.
00:58I'd be happy to help.
00:59How about if I show you around the garden?
01:01That would be great.
01:03It's amazing to see so many different kinds.
01:05It's also interesting to see what they have in common.
01:08Notice anything?
01:09Yeah, they're not brown like mine.
01:12Anything else?
01:14Here's a hint.
01:16Look at the leaves.
01:19Hmm.
01:20On each leaf, the right side looks like the left side.
01:23Right.
01:23Right.
01:24And if you fold this down the middle, both sides match up.
01:29Many leaves are symmetrical.
01:31Symmetry is just one of the patterns found in nature.
01:34Wow!
01:35These flowers are symmetrical too!
01:37The right side looks like the left side.
01:39Right.
01:40But if I also rotate the flower just the right amount...
01:43It looks like it did before you rotated it.
01:47That pattern is called rotational symmetry.
01:50Wow!
01:51These flowers have rotational symmetry too.
01:54Why do plants have symmetry?
01:56No one knows for sure, but scientists think it helps the plant get the sun and nutrients
02:01it needs to grow.
02:03Symmetry also may help plants stay balanced so they don't fall over.
02:07I just noticed something else.
02:08Every one of those purple flowers has five petals!
02:11You just found another pattern.
02:13It so happens that lots of different flowers have five petals.
02:18Like those yellow ones.
02:19Mm-hmm.
02:20And those pink ones.
02:21Right.
02:22Like the plants, my symmetrical brain needs some nutrients.
02:25You want an apple?
02:27Yes, thank you.
02:29I'd like to show you something.
02:32Awesome!
02:33A star is born.
02:36Every apple blossom turns into an apple with five seed compartments.
02:40Every apple?
02:42Yup.
02:43Guess how many petals an apple blossom has.
02:46Five.
02:47You got it.
02:48That is so cool.
02:49I know a lot more about plants than I did before, but I still don't know how to keep mine
02:54alive.
02:55I water them every day.
02:58Every day?
02:59Right before breakfast.
03:00I think we just uncovered another pattern.
03:03You water your plants every day, you're probably over-watering them.
03:07You're killing them with kindness.
03:09How is that possible?
03:11When you over-water, the soil gets so soggy that oxygen can't reach the roots,
03:15then the roots rot and the plant dies.
03:18That's great news!
03:20It is?
03:21Yeah, because all I have to do is change my pattern and water them less frequently and they'll live.
03:27I can have a green thumb!
03:28You have aer.
