why do hypocotyl and epicotyl were used for the extraction of subcellular components?

Answer 1

Hi, hope this of some use to you:

The multicellular body of a flowering plant is composed of 3 types of vegetative organs: roots, stems and leaves. The flower is considered a greatly modified stem bearing greatly modified leaves. The following topics will be covered in this lab: seed structure, root structure, stems structure, and leaf structure.

The process of sexual reproduction in angiosperms produces seeds, which are used to propagate the species. Each angiosperm seed contains a dormant embryonic sporophyte and some endosperm. As the embryo germinates, it utilizes the endosperm as a source of stored food. In the following exercises we will examine basic seed structure and seed germination in monocot and dicot seeds. Monocots have one cotyledon (embryonic seed leaf) and dicots have two cotyledons.

The 2 fleshy halves, which make up most of the embryo, are the cotyledons. The smaller part of the embryo may be viewed as a miniature plant. It consists of a hypocotyl, which is below the point of attachment of the cotyledons, and an epicotyl, which is above the point of attachment of the cotyledons. The tip of the hypocotyl is called the radicle and will give rise to the primary root of the bean plant. The epicotyl consists of the 2 small foliage leaves (plumule) and a minute shoot tip. Examine closely the small part of the embryo identify the hypocotyl, cotyledons, and the plumule.

Answer 2

Hypocotyl And Epicotyl

Answer 3

Easier to extract components with younger cells since plant cells that are older have thicker cell wall.

Answer 4

LMAO this is great! lol. Love the duct tape one it's so true...and the mouse trap. OUCH! lol

Answer 5

secret!
