In a membrane, the tail of the phospholipids in one monolayer face the tail of the phospholipids in the other monolayer.
<h3>
What is cell membrane?</h3>
- The cell membrane is a biological membrane that separates and protects the inside of all cells from the outside environment.
- It is also known as the plasma membrane (PM), cytoplasmic membrane or plasmalemma (extracellular space).
- The cell membrane consists of a lipid bilayer, which is made up of two layers of phospholipids interwoven with cholesterol (a lipid component) to maintain proper membrane fluidity at different temperatures.
- Furthermore, membranes are composed of membrane proteins, such as those that cannot be separated across the membrane and function as membrane transporters, and peripheral proteins that simply attach to the outer membrane of the cell and function as membrane transporters. enzymes to help the cell interact with its environment.
- The integrated glycolipids of the outer lipid layer perform a similar function.

Answer:
models are universal. option A
Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte
Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)
Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition
Mitosis-both (mitosis occurres in spores)
Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.
Answer:
D
Explanation:
The cuticle of a plant helps protect its aerial epidermis from things like environmental stresses and desiccation.
Long answer short- to reproduce cells.
