Plant Multicellularity

Plants are made of many cells working together.

Plant Producers

Plants make their own food through photosynthesis.

Photosynthesis Equation

Carbon dioxide + water + sunlight → sugar + oxygen

Nonvascular plant size limit

Nonvascular plants stay small because they lack a system to transport water and nutrients effectively to all parts of the plant.

Can objects have both potential and kinetic energy?

Yes, an object can have both kinetic and potential energy simultaneously. For example, a roller coaster moving down a hill has kinetic energy (motion) and potential energy (height).

What affects gravitational potential energy?

Gravitational potential energy depends on the mass of the object and its height above a reference point.

Example of Potential & Kinetic Energy

A skateboarder at the top of a ramp has potential energy due to their height. As they roll down, potential energy converts to kinetic energy as they gain speed.

Elastic Potential Energy

The energy stored in an object when it is stretched or compressed. Think of a rubber band!

What is the relationship between elastic potential energy and stretch?

As you stretch or compress an elastic object more, its potential energy increases. The more distorted the shape, the more energy is stored!

What affects kinetic energy?

The amount of kinetic energy an object has depends on its speed and mass. The faster it moves or the heavier it is, the more kinetic energy it has.
