Paul surveys the Kingdom Plantae. He begins with a brief description of the phylogeny of land plants. He then describes the defining characteristics of plants, including cell walls, embryophytes, alternation of generation and photosynthesis. He briefly describes the sporophyte and the gametophyte. He finishes with brief discussion of plant evolution and includes major divisions, like bryophytes, ferns, gymnosperms, and angiosperms.

Used your videos in high school and here I am using them again in college. Thank you :D
I'm not alone! XD
AznCrazy95 same here!
You are the best teacher!! I have a great BIO teacher but when im preparing for an exam I watch your videos over and over and my grades have improved tremendously!! THANK YOU SO MUCH!!
You helped me through highschool bio, and now you are helping towards my bio Degree! Thanks a bunch Mr. Anderson!
Thank you very much for helping all of us! Your generosity is unmatched...
Why is this so much easier to understand then my professor
Why do universities even have lectures...This is honestly exponentally better than any lecture i've had, ffs education system :/ But thank you Bozeman Science, thank you very much.
because they have to justify those 9K a year fees somehow....
In this video you are getting the breadth but not the depth. In my Plant Biology class I got sooo much more than this. He is a good teacher but this does not replace a good professor
Following AP Biology in high school, I still watch your videos for my college biology courses. I can't thank you enough!
Stop reading the comments and watch the video
No
I poo
Ya caught me XD
No thx 🤣
Who asked for your opinion???
Awesome and Clear explanations, i wish you went into more details !
Thank You!
Thank you! I really needed this quick summary to polish up for my AP test tomorrow!
Thank you for the simplistic explanation, your videos truly help me understand biology better.
*2020 assignments be like*
Cuz of the 🦠
not funny never gonan give u up never gonna let u down
and something forgot the lyrics but ur gayyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
Holla if you're here for your Biology course XD
holla
Holla
damn it excludes me cuz this is for my music class
holla
@@joeware9934 holla
taking a break from sending out applications this Friday night to learn about plant evolution after seeing some cycads in florida last week. thanks for the nice video :)
Ap Bio had me like O_o Thanks so much Mr. Anderson :)
Well done, thank you!
Very Nice Summary, keeps it simple for me!
THANKS MR ANDRSEN!!!!!!!!!!
VERY EDUCATIVE THANK YOU.
thank you mr. andersen!!!!
You are a great teacher. :)
I've learn't more from you in a day than I have in a year.
You mean in 7 minutes and 46 seconds
Very helpful!
Thank you!
Thank you!
Thanks for sharing
Fantastic!! Really very useful..
Thanks for video, it is really useful but could you please give more specific information because those are just very basic ones even though I am on IGCSE
Thanks in advance
YOU SAVED MY LIFE IN PLANTS!
Just made my lesson SO FASCINATING THANK YOU ! I was desperate cause I didn't undertand a thing 😭😭
Thank you!!!! :)
I'm just gonna stay up all night watching these videos for tomorrow lol
Thank you.
Not sure what triple fusion is, but I'm pretty sure double fertilization does occur in angiosperms. Mr Andersen talks about it in his video, "Plant structure"
Hm, interesting. I read a current article saying that the evolution of angiosperms wasn't as dependent on coevolution with insects for pollination as previously thought. A survey of fossils revealed conclusively that they were already highly specialized and diverse BEFORE there was evidence showing that plants and insects began working together.
very well made
sir,hats off for u...thanks alot
I love this!
whos here because they have to study for a test but never listened to what the teacher was saying???
He's a nice fellow but god awful in lecture
Before i got into high school i had always thought kelp was a plant
this helps alot in my agriculture course
I love this guy!
Thanks, this video was a lot of help! :]
Mr. Andersen, are the two major plant divisions bryophytes and tracheophytes? Can you tell me more about bryophytes and tracheophytes? Thanks
Thanks!
Jack and Zuza say we wuv u - Luv ya Shento xxoo
Do you have any video about similarities in cytokinesis between plants and animals??
I have a question, what are plants having odd mechanism in acquiring nutrients?
"I love plants cause i eat them." ^.^ I love u Mr. Anderson!
very informative
Thankyou
You helped me in my progect ty
very helpful
cramming for ap bio test tomorrow morning!
Howd you do?
Yess thanks sir!! Regards to sir dewitt! Haha i support!!
"I love plants because I eat them"
Gonna need that glucose for cellular respiration through the process of glycolysis bro
the fact that the new cliffnotes doesn't come out untl april is seriously givng me anxiety
thanx
Hi Mr Anderson
My name is Tessa
I am a gr11 biology student currently studying the four plants you have shown in this video.
Can you maybe make a video going into detail on each of them? It would really help.
+Tessa Harmse He made this video 4 years ago...........
Just use a textbook
+Oh Sykezz
yeah you're right
what were most of the questions about? do you remember?
great video and explanation but me and this subject just don't get along
Does alteration of generations occur in both angiosperms and gymnosperms?
It occurs in all land plants I believe i.e. angiosperms, gymnosperms, liverworts, hornworts, mosses, ferns, lycophytes
PLVS VLTRA
neat.
strange how cycads are classified as gymnosperms, but they do have a layer around the seeds. I guess it is kind of like how we now think turtles are descended from diapsid reptiles who lost the temporal fenestra
helpful ass always thank you.
me too my friend, me too
Really? I like how Mr Andersen's videos are shorter, but it's nice to have Khan Academy too to clear up any confusion I might have left :P
djis wya?
water potential video please
i guess 2 main type in plant kingdom are cryptogamae and phanerogame.
and cryptogamae include thallophyte, bryophyta and pteridophytae
der is not a single word called tracheophytes
hello sir
i have a question for you
how brayophytes plants grow through gametophytes generation ?
plz tell me through your video as quickly you can
i cant understand this video
The gametophyte (n) generation is when the pollen (male) from the pollen cone enters the ovulate cone's (female) ovary and undergoes meiosis producing sperm cells (n). Meiosis also occurs within the female part's megasporangium which produces an egg or megasporocyte (n). One sperm cell (n) fertilizes (+) the megasporocyte (n) and grows a seed (2n) in the cone's woody protection. (n+n=2n) Once it's ready, the cone opens up releasing the seeds.
Thumbs up if cramming for AP Bio test on monday!!
where blooming trees fit here?
how did plants evolve? no explanation provided?
Be patient. It is coming.
lol, I got lots of time
same i have all the time in the world...
Luke Clifton i’m from the future. you’ll have all the time in 2020 due to quarantine
and my teacher hardly knows how to turn on a computer..... :P
ha lol
THERE WERE ONLY 1-2 QUESTIONS ON PLANTS. I SPENT SOOOO MUCH TIME STUDYING THEM ON MY OWN
btw gymnosperms are no longer monophyletic
Here for College Plant Biology course :D
Aren't ferns also called pteridophytes????
gamerdude612 yea
@sandeep88214 I kno I'm late but it's a... My bio teachers says there are 3 f specific to angiosperms that I must remember... Flowering, another f word, and double fertilization...
Hard to believe anyone's still discussing theory of evolution.
wait a minute meiosis is not the one responsible for female gametes and male gametes? why it says mitosis ?
biology class yaaaaaa
The way that Plantae and there are other groups in way bottom of the phylogeny chart. The four groups that share a common ancestor are the bryophytes, ferns, gymnosperms, and angiosperms. It also shows the movement from water to land but they would contain similar characteristics such as the way that they get their food source and the structural features. They contain two life cycles in them where the stage of the sporophyte (diploid) and the second stage gametophyte (haploid) but they both take place in a multicellular process. They would use photosynthesis to make the food source that they need but also can undergo cellular respiration to release energy. _ thank you it was very informative.
Watched
Haploid means half the copies of the chromosomes, monoploid means one copy of the chromosome.
Some plants have more than two copies of a chromosome this is called polyploidy.
Wheat for instance are hexaploid so each type of chromosome has 6 copies, their haploid (half set) is 3 copies of each type of their chromosomes.
The haploid set of a diploid is of course one copy of each chromosome.
can you give me your script?
helpfull
Haha, Khan Academy doesn't do it for me in Biology. For me it's Bozemanbiology + Princeton's Cracking the AP Biology Exam + Kaplan's AP Biolgy = hopefully a 4, because I need that for college credit!
does he still read these comments :O
which event is unique to angiosperms
a) double fertilization
b) triple fusion
c) both
d) none
please do help me i have exam .pleeeeeese
Are you still taking the test?
God help us!
Here in 2019?
WE ARE SIMPLY PARASITES ON PLANTS xDD
nah
MR ANDERSON...... COME ON MAN... WHERES NEO
May 14th... I'm scared....
Bozeman bio + khanacademy + cliffnotes AP bio prep = 5.
Did u end up getting a 5?
I’m just tryna do my homework that is writing a whole page and I only have a day left I waited until the last minute does anybody have any plant tips
That's when the AP exam was last year
