Answer:
Diffusion is the movement of molecules from an area where the molecule is in high concentration to an area where the molecule is in lower concentration. ... Facilitated diffusion is the movement of a molecule from an area of high concentration to an area of lower concentration with the help of a protein channel or carrier.

Seaweed is a type of algae.
Explanation: Seaweeds are a group of photoautotrophic, multi-cellular algae occurring in marine environments.
Indeterminate cleavage results in identical cells capable of forming an embryo while determinate cells do not result in cells which are capable to develop embryo.
Indeterminate is superior to determinate cleavage.
Explanation:
Cleavage is the division of cells in the early embryonic stage. The two stages of cleavage described here are:
In indeterminate cleavage or regulative cleavage occurs when an embryo divides, each cell is capable of developing into complete embryo. eg: Deuterosomes
In determinate cleavage the resulting embryonic cells of blastomere cannot develop into embryos. It is also called as mosaic cleavage. The essential part of the cell might be missing which does not let the cell survive. eg: Protosomes
Indeterminate cleavage is of great importance as the cell grows and can produce new organism. The complete identical twin is formed. Its application can be seen in tomato plants.
3. All animals do not display intermediate cleavage because growth from intermediate cleavage is continuous and does not stop after adulthood which is not possible in animals.
Base on the question that asks to choose among the following choices that is significance of the apical meristem, base on the fact, apical meristem is found at the apices or tips of the plant, both the tip of the shoot and the root and is a region of actively dividing cells. Base on that the answer would be "It provide strength to the plant by facilitating secondary growth"
