Answer:
Phospholipid bilayer determinates which molecules can enter or exit the cell so its purpose is to be a checker in the middle. Cell membrane determinates the structure of the cell and it is the connection to the rest that happens in a cell.
Explanation:
Molecules can move in 2 ways: passive and active.
The only difference is the energy that is needed to do the movement.
In passive mechanisms, energy is not used, while in active transport, energy is needed. Diffusion or passive transport are moving the concentration from hight to low so the energy is not necessary. Active transport moves from low to a high concentration and it uses metabolic energy.
Answer:
Water should be the answer.
Answer:
Fertilization
Explanation:
Egg and sperm are cells known as gametes produced by the GAMETOPHYTE of a sexually-reproducing organism via meiosis. Since egg and sperm cells are produced through meiotic division, their chromosomal number is reduced by half of the parental organism. Hence, sperms and eggs are haploid cells (n) produced by a diploid organism (2n).
Sperm is the male gamete while egg is the female gamete. These two haploid gametes fuse in a process called FERTILIZATION, to produce a diploid ZYGOTE that eventually grows into the diploid structure of the organism called SPOROPHYTE. This system of reproduction called ALTERNATION OF GENERATIONS is used by lower and higher plants.
Okay so i hope this help but i think its this:
1. chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section
2. light (either natural sunlight or artificial light, like from a light bulb)
3. carbon dioxide (CO2)(a gas found in the air; one of the gases people and animals breathe out when they exhale)
4. water (which the plant collects through its roots)
5. nutrients and minerals (which the plant collects from the soil through its roots)
Did researching for you so I hope this helped? :)
