Which statement describes the transport of nutrients in nonvascular plants?

Nutrients are absorbed from the environment and pass from cell to cell.

Nutrients are absorbed from the environment and pass through the vascular
tissues.

Nutrients are absorbed through the roots and pass from cell to cell.

Nutrients are absorbed from the environment and pass from cell to cell.  

Explanation:

Nonvascular plants do not have any special internal channels to carry nutrients. Instead, they absorb nutrients directly into their leaves.

The nutrients then move throughout the plant by diffusion from cell to cell.

B is wrong. By definition, nonvascular plants have no vascular tissue.

C is wrong. Nutrients that are absorbed by the root must be transported through vascular tissue.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
