Biology Module 2

At the time of Priestly's Candle, mouse and plant experiment, carbon dioxide and oxygen had not yet been discovered.

In the source-to-sink theory for the movement of sugars in a plant, the source and sink refer to:

If radioactive Carbon dioxide (CO2) gas is provided to a plant, in which molecules in the plant will it be seen?

Models should be adjusted when new information is discovered that does not fit the model

The movement of sugars in a plant is

What plant structure is shown in the image below?

The process of transporting water through a plant from the roots to the leaves via the XYLEM is known as

Priestly could relight a candle in a bell jar after 27 days. This showed that plants produced

The model for cell membranes changed in 1972 to the

What plant structure is shown in the image?

What evidence does NOT back up the current model of a membrane

What plant structure is shown in the image below?

The process of transporting sugars through a plant from the leaves to other tissues occurs via the:

Plants produce oxygen during photosynthesis. Where does it originally come from?

Identify structures 1 and 2 in this image

What plant structure is shown in the image?

Making models in Biology helped my understanding

C-14 is a radioisotope of carbon

Models are NOT good for:

The process of transporting sugars through a plant via the PHLOEM is known as

The most common form of carbon is C-12
