Answer:
The cell membranes are <u>Selectively permeable</u> or <u>semi-permeable.</u>
Explanation:
The cellular membrane allows the free passage of only a few substances while it blocks the pass of others.
Cellular membranes are <em>composed mostly of lipids arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other</em>, constituting the internal part of the membrane.
Through this lipidic bilayer, some molecules can move from one side of the cell to the other. This free movement is called simple diffusion, and it depends on the substances' sizes and their concentration on each side of the membrane.
The membrane is selectively permeable because it only let small substances to move through it, with no protein mediating their passage.
Answer:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Explanation:
The equation is in words is:
carbon dioxide + water yields glucose + oxygen
Photosynthesis allows plants to use carbon dioxide from the air around them and water, from the air or ground, to produce glucose. Oxygen is a byproduct of this. The glucose is used in cellular respiration to produce ATP, what they use for energy. Humans and other mammals do not do photosynthesis, so we have to get our glucose from the food we eat.
