2. The principle pigment in plants is

Chlorophyll

ATP

Carotenoids

NADPH

3. A carrot is an example of a taproot system because

It has one large root and many smaller sized and many smaller-sized branched roots

It has many equally sized branched roots

It has no roots

The carrot itself does not grow in the ground

4. The cuticle is found at the top of the leaf and prevents water from leaving the leaf by evaporation. The picture below illustrates one of the features of the cuticle that aids in its function. The best description for this feature is

The cuticle is composed of a waxy substance which prevents water loss.

The cuticle is composed of a hydrophilic substance so water can pass readily through the cuticle

The cuticle offers protection since it is very flexible.

5. The prefix auto in the term autotroph, refers to the facts that autotrophs

Produce their own food

Produce their own sunlight

Are tertiary consumers

Need to obtain food from other sources

A. and D.

6. Although the Calvin Cycle is also called the dark reaction, it cannot occur without light because

It cannot function without ATP and NADPH produced in the light reactions

It needs carbon dioxide to function

It requires the addition of a glucose molecule

The term "dark" reactions does not apply to the fact that light is necessary

7.

The most light is absorbed by chlorophyll B at

450 nm

550 nm

400 nm

650 nm

8. Adhesion, cohesion, transpiration, and capillary action aid the plant in

The production of sugar

The transport of water

The transport of sugar

Increasing surface area

9. How come chloroplasts are not found in the cells of a pigeon?

Pigeons are autotrophs

Pigeons can survive in extreme conditions, like New York City

Pigeons are heterotrophs

Chloroplasts are only found in prokaryotic cells

10. How does the presence of enzymes change the speed at which the light dependent and independent reactions occur?

Enzymes slow down both reactions

Enzymes are not present in either reaction

Enzymes speed up both reactions

11.

The veins shown on this leaf are most likely composed of

Chloroplasts and spongy mesophyll

Stomates and guard cells

Xylem and phloem

Upper epidermis

12. The Calvin cycle takes place in the part of the chloroplast called the

Thylakoid membrane

Stroma

Grana

Inner membrane

13. Which of the following is produced by both cellular respiration and the light-dependent reactions of photosynthesis?

Glucose

ATP

Carbon dioxide

Pyruvic acid

Oxygen
