Great information. Just to clarify tho:"Spanish moss (Tillandsia usneoides) is not parasitic. It an epiphytic flowering plant that performs photosynthesis.
The part about the woody vascular system was full of errors. The illustration showed the cambium layer as being as thick as the phloem and xylem layers when in actuality the cambium ring is microscopic in thickness. The speaker kept referring to the thin phloem layer as the "sapwood" and the xylem layer as the "heartwood" when in actuality the LIVING part of the xylem is the sapwood and the DEAD part of the xylem is the heartwood. Also, the illustration (and speaker) confused the term "stipule" with "pulvinus". They're different structures.
Would have been MUCH more informative and enjoyable if they had focused the camera on the pictures instead of the instructor so we could study what she was saying instead of watching her stare up at the picture WE couldn't see.....
well, it is a free video on a course that you have to pay for, so you could always just listen to what they are saying and take that to the program you are signing up for....
@@jackd1984 and us in UA-cam aren't going to be accredited for learning the info from watching this. Those who paid will end up with credits or certifications to go toward their professional life.
Plants respire all the time, not just at night, they are growing/ repairing etc. all the time and therefore using energy produced from respiration (from the sugars and oxygen produced by photosynthesis)
Can anyone clear this up for me...What makes a parasitic plant a plant if they don’t photosynthesis, wouldn’t that make them Heterotrophs? What’s the difference between them and a fungi? For example why isn’t a white Indian pipe considered a fungi?
Most parasitic plants exhibit near-normal levels of photosynthesis like their autotrophic ancestors, whereas others are incapable of photosynthesis such as the derived endophytic holoparasites. The white Indian pipe is an herbaceous perennial plant whose hosts are certain fungi that are mycorrhizal with trees, meaning it ultimately gets its energy from photosynthetic trees. Fungi are a group of eukaryotic saprotrophic organisms including yeasts, molds and mushrooms while parasites are a group of organisms that live on or inside another organism obtaining nutrients.
good day madam would like to learn a lot from horticultur all the ways from namibia ,how can i get hold of you,so we have more information in horticulture , this lesson was much production

I think they mean parasitic because it grown in other plants. It doesn't support itself

I second that, I was listening to it with my botany book under my nose and I was like wait.... she gots it completely backwards
Exactly but if you buy the books and self teach you will not be accredited

Pause it

People who pretend to be landscapers damage trees. Real landscapers(which are a small percentage) don't damage trees.
This was an interesting one and can you send readable mannuals?
Hey @Byron Asakawa! Thanks for doing what you do. Helps a lot! subscribed!
Is it really a lecture if there isn’t a wave a coughs every other second 😂✨🦋
Please use good quality mic ... marvelous video
hi, I have done horticulture, can I advance it over there, I really like the teachings thank you?
Nice video interesting too ❤
Does anyone know the name and author of the "sunset book" the teachers keep referring to?
Loving these videos so far. Thanks Byron :)
Pretty sure it would be Sunset Western Gardener, by editors of Sunset
What book are they studying from??
