1 Some plants can be grown in water using the technique of hydroponics. The roots are in water and
supplied with the ions that they need at the concentrations that support maximum growth. Some
ions can be absorbed both by diffusion and by active transport.
(a) (i) State two features of diffusion that do not apply to active transport.

# Diffusion is a down hill process.(flow is from higher concentration to lower concentration)

# It does not require energy.

but,

# Active transport is a uphill process.(flow is from lower concentration to higher concentration)

# It requires energy.

its like this, "if i give a plant an unlimited amount of sunlight,then the plant will grow to its largest possible size."

hope it let me know if it does or doesn't =^-^=
