The use the physical principle and property called "Turgor Pressure".
Water is pulled up through the plant's xylem tissue by a process called transpiration. Transpiration is the evaporation of water from the leaves, creating a negative pressure that pulls water up from the roots. This process is driven by the cohesion and adhesion of water molecules, allowing water to travel up tall trees against gravity.
The force that acts against gravity is called the normal force. It is exerted by a surface supporting an object, pushing upwards to prevent the object from falling due to gravity.
The force working against the buoyant force is gravity. Gravity pulls objects downward, while the buoyant force pushes objects upward when they are immersed in a fluid.
Capillary action & osmotic pressure.
Any upward force works against gravity,since they act in opposite directions.
The force that supports an object against gravity is called the normal force. It is exerted by a surface to prevent objects from falling through it. The normal force equals the force of gravity acting on the object.

Leaves fall down due to the force of gravity pulling on them.
Buoyancy is the power to float or rise in a liquid and it acts against the force of gravity.
Work is said to be done against the force of gravity when an object is moved vertically upwards, against the force of gravity, over a certain distance. In this case, the force applied must be greater than the force of gravity acting on the object for work to be done against gravity.
the force of gravity
The force that acts against the force of buoyancy is gravity. Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in the fluid. Gravity, on the other hand, pulls objects downwards.
