Seeds have cotyledons from where they can draw their nutrient in their early stages of development. Pollens must draw their nutrient from their environment from the start. Seeds have an outer coating (testa) that protects the embryo and enable it to remain dormant in the soil until right conditions for growth set forth Seeds have a fully developed embryo that can begin to grow immediately there are right conditions. However, pollen has a single cell instead of an embryo, which must undertake cell division and specialization before beginning to germinate

suppopse you were going to deisgn a system for the rapid diffusion of oxygen across a phosphlipid bilayer. according to fick's l
Llana [10]

Answer:

According to Fick's law, the rate of diffusion of any substance across any barrier is<u> directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.</u>

<u />

Thus the rate at which oxygen will move across the phospholipid  bilayer will depend on the concentration or amount  per mole  of the oxygen molecule hitting the phopholipid at  a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its  movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules  increases.

Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid  bilayer should also be maximized. the distances between the phopholipid and the  vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law  has been applied , and therefore maximum oxygen molecules can diffuse across.

How is a dicotyledonous leaf adapted for maximum sunlight and carbon dioxide for photosynthesis? 20 Points if ya help meh out lo
jok3333 [9.3K]

Answer:

They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
