Is this the perianyh and calyx?

To clarify, I'm referring to the white and orange membrane looking piece on top. The terminology section of my Marijuana Horticulture Fundamentals book states that growers commonly and incorrectly refer to the bracts as calyxes or false calyxes. It then states "cannabis flowers do have a calyx, which few growers recognize because it is barely perceptible without a microscope. The cannabis calyx is one part of the perianth, a nearly transparent, delicate tissue that partially encloses the ovule (prospective seed)." It goes on to state that the perianth consists of a corolla and a calyx, that it is about 6 cells thick, and that it tightly clasps the seed and often contains tannins which give seeds their mottled or speckled coat. Any botany students want to chime in here? Im just looking for verification or if I'm wrong, please a link to related pics of what that part on my seedling is and what a true perianth and calyx look like on a cannabis plant. I had a hard time googling one. Thanks again!

@frigault You’ve never heard growers refer to cotyledon as sucker leaves slang? Ok i’ll blame my hippy SoHum parents. You have the correct scientific terminology and thats the right answer per the post. Can we agree he’s not looking at a calyx...? Appreciate your answer. Not sure how far off we are...those suckers turn yellow and die off as soon as their job is done (nutrient depletion) as the first real leaf sets begin to grow. They are completely unique from those other sets of leaves...as i stated...a d i’ll stick to that. I suppose ill refrain from slang or simplified answers in the future. All good. cheers

Negative highaltitude... The sucker leaf like yiu call it are called cotyledon they are what drives the plant by turning sun energie in to sugar to help the plant true leaf feed dyring seedling phase they are also stocked with nutrients abd feed it to tge plant till the root are mire devolope..

On the inside of the seeds you can find a substance called albumen, which is a nutritional reserve that keeps the embryo healthy until germination; it’s also the seeds initial source of energy once it begins germinating. Now, for the center of the seed, home to the precious embryo from which your new plant will grow from. It contains the plant’s genetic code alongside four other parts; the radicle, the hypocotyl, cotyledons and gemmules. The radicle is the embryonic root; this is the part of the seed where roots come from. The hypocotyl is known as the embryonic stage, and the cotyledons are in charge of those first few leaves that you can see once the seed germinates. 🤘😤

negative, Ghost Rider. Love that you want to learn and have correct terminology. That is not a calyx and you won’t be seeing those for awhile. The first two leaves, completely unique from any future leaves that will grow, pop out of the middle of the seed’s split. These leaves are called sucker leaves and mark the beginning of more leaf growth. Good luck
