Explanation: fertilization occur after the fusion of a haploid male and female gametes to give a diploid zygote. The male sperm fuses with the female egg in the ovule to give an embryo. For angiosperms the male sex cell is located in the pollen in the anther which is carried to the stigma where the female sex cell is located either of the same plant or different plant. For gymnosperms the male pollen is found in the cone from where it is then transfer to the female cone. The ovule developed into the seeds after fertilization and the ovary develops into fruits.
Pure solvent diffused through a membrane but solutes do not.
Explanation:
Osmosis is process where solvents or molecules move from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane which tend to balance the concentration of solutes. Osmosis is passive transport i.e it does not require energy for movement.
