Adenine, guanine, thymine and cytosine are the four nitrogenous bases that are attached to a sugar molecule<span> on each </span>side of the ladder<span>. When a phosphate, a sugar and a base form an attachment, they create a sub-unit of </span>DNA<span> called a nucleotide. Each nitrogenous base is held together by a hydrogen bond.</span>
The membrane is permeable to the non-polar molecules like CO2.
Sodium also can diffuse through the membrane but it needs channels (or transmembrane transporters). the same thing for the glucose and the starch (these transporters can transport molecules passively or actively).
But the CO2 can pass the plasmic membrane easily without channels because it is partially water-soluble, and it is non-polar, so it has no charges, and can pass through the amphiphile phospholipid molecules.
Plant cells have a cell wall, a large vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell. It provides structural support and protection.
I hope this Helped!
The Integumentary System. I might be wrong but I just looked it up and that's the answer I got. Hope it helps:)
HI Mate! The right answer is vascular tissue!
