Biology
1 answer:
Novay_Z [31]3 years ago
8 0

Answer:

Major difference between active transport and facilitated difusion is:

Active transport moves substances against the concentration gradient.

Facilitated diffusion moves molecules through the plasma membrane.

Explanation:

  • Active transport involves the transport of molecules against the concentration gradient.
  • Since molecules move from lower concentration to higher concentration this mode of transport needs energy.
  • Facilitated diffusion do not require energy  but need some other molecule or carrier protein to transport the molecules across the membranes.
  • In facilitated diffusion, the molecules move from their region of higher concentration to the region of lower concentration.

Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).
