What Are Photosynthesis and Respiration?

As this situation changes in the future with population growth and more demands on primary productivity, we know from our understaning of energy flow in natural systems that "Ecological Efficiency will get us in the end" - and that is the last take-home point for this lecture.

Photosynthesis and Energy Flow - Invasive Species - …

Remember that cellular respiration is the reverse processfrom photosynthesis, as follows.

Energy Flow in Ecosystems - Earth Online Media

Some of the light misses the leaf chloroplast, where the photsynthetic reactions occur, and much of the energy from light that is converted by photosynthesis to carbon compounds is used up in keeping the plant biochemical "machinery" operating properly - this loss is generally termed "respiration", although it also includes thermodynamic losses.

Energy Flow in Ecosystems Energy capture and use

The roots absorb the water and the water is transported throughout the plant with vessels.
Phloem transports sugar and nutrients and moves up and down the plant stem.
Stimulus and Response
Stimulus is an action that causes a response
Response is a reaction to the stimulus
How the roots grow
Where the light is
The direction of where a plant grows
O2 is released
Water is "pumped up"
Turgor Pressure
Physical and Chemical Change
Physical change is a change in appearance and no change in the atomic structure
Chemical change is a change in the way the molecules link up or make a new substance

Germination is process by which a plant grows from a seed.

The figure illustrates how closely photosynthesis and respiration are linked. As you can see, thanks to these two life-sustaining processes, plants and animals depend on each other to survive.

What's the difference between Cellular Respiration and Photosynthesis

Chemical energy makes the
organism performs functions such as movement, growth, reproduction.
It must be
replaced as used.
Many organisms can convert light energy into chemical energy through photosynthesis.

What Are Photosynthesis and Respiration? - dummies

All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight.

Photosynthesis is the first stage of energy flow …

Photosynthesis occurs during the day
2 types of Radiant Energy:
Invisible (Ultraviolet Light)
Visible (Light you see from the sun)
The other 30% is reflected back into space.
Thermal Energy
is energy that is
transferred during heating or cooling.
warms the atmosphere, evaporates water and produces winds.
cannot provide organisms with energy to function
Chemical Energy
can be
stored in cells and released when needed
