Diffusion, osmosis, facilitated diffusion are the passive transport.
What is osmosis ?The process in which solvent molecules pass from a lower concentration region to a higher concentration solution through a semipermeable membrane called as osmosis.
It is a passive transport as no external energy is needed.
Osmosis, like a diffusion not require the input of energy and it moves water down or against the concentration gradient.
When a living plant cell kept in a sugar or salt solution, water diffuses from the cell sap out through the cell membrane called as exosmosis.
The cell causes shrinkage of the protoplasm due to water loss, where the cell undergo a condition called as plasmolysis or necrosis.
When the plasmolyzed cell is placed in distilled water, the cell regains it’s turgidity and also the original shape and size by a process called endosmosis.

HOPE IT HELPS2. Which determines the identity of an element
A. its mass number
B. the charge of the atom
C. the number of its neutrons
D. the number of its protons
The identity of an element is primarily determined by: D. The number of its protons.
The identity of an elementThe number of protons in an atom's nucleus is known as its atomic number. Each element on the periodic table has a unique atomic number, which corresponds to the number of protons in the nucleus of its atoms. For example, hydrogen has an atomic number of 1 because it has one proton, while carbon has an atomic number of 6 because it has six protons.
The atomic number is crucial in defining the identity of an element because it distinguishes one element from another.

Fall brilliance of the leaves is a result of chlorophyll decomposition, which causes the green color to disappear and the yellow to orange hues to appear.
What is chlorophyll brake down hypothesis?If plants degrade the chlorophyll and move it out of their leaf before the leaves fall, they can save energy.
Plants are capable of reabsorbing the substances that go into making chlorophyll. However, due to changes in temperature and daylight hours in the fall, the leaves stop generating food.
As a result, during the summer, chlorophyll is continuously degraded and rebuilt in tree leaves.
Therefore, chlorophyll brake down hypothesis that explains why you think leaves change color in the fall.
