poliinators and flagellated sperm

Structure of cycad?

The megaspore's contents divide during pollination to create the many-celled gamateophyte known as the endosperm and archegonium. The wind-borne male gametophyte (microspores), which at this point is made up of prothallus cell, an antheridial cell, and a big tube cell, gets trapped in a micropyle opening with a sticky fluid. The archegonia chamber is filled with the imprisoned microspore. The discharge of antherizoids only results in one of them entering each oospore and joining the female nucleus. In the ovule, the zygote is created, and it later matures into a seed. The life cycle starts over when the diploid seed germination produces a fresh sporophyte plant.

All other groups of plants produce sperm without swimming flagella, while cycads and ginkgo trees produce sperm that swims.

Furthermore, cycads have specialist pollinators, beetles, unlike other gymnosperm groupings.

How do metabolic pathways keep from reaching equilibrium?
wlad13 [49]

Answer:

The metabolic chemical reaction is reversible, and they too would attain equilibrium if they take place in a test tube separately. However, if a cell attains metabolic equilibrium it is considered as dead. Thus, a cell in the body is not in equilibrium.  

The spontaneous flow of substances within and outside of the cell prevents the metabolic pathways from attaining an equilibrium, and the cell persists to perform the work all through its life. This principle is demonstrated by the open hydroelectric system.
