This is a substance that is METABOLIZE by or INCORPORATED into an organism.

Nutrient

1

This type of organism MAKE their OWN FOOD by using inorganic molecules to make organic molecules.

Autotrophs

2

This type of organism use organic molecules FROM OTHER ORGANISMS to fuel, build and support.

Heterotrophs

3

These are substances needed in plants in order to COMPLETE their REPRODUCTIVE CYCLE.

Essential Nutrients

4

What 3 things occur with LIMITED ESSENTIAL NUTRIENTS.

1.) REDUCE GROWTH and REPRODUCTION of plants

2.) DEFICIENCY SYMPTOMS

3.) ADAPTATIONS for acquiring essential nutrients

5

What are some ADAPTIONS to SHADE? (3)

1.) THIN LEAVES

2.) Production of MORE CHLOROPHYLL to MAXIMIZE PHOTOSYNTHESIS

3.) ARRANGEMENT of leaves/branches

6

What are some ADAPTIONS to TOO MUCH LIGHT? (2)

1.) Chloroplasts CHANGE POSITION to AVOID DAMAGE

2.) ADDITIONAL PIGMENTS are produced

7

What COLOR are CAROTENOIDS?

Yellow/Orange

8

What COLOR are ANTHOCYANINS?

Red/Purple/Blue

9

What are the HARMFUL EFFECTS of EXCESSIVE LIGHT?

Destroys protein and DNA

10

What are SYMPTOMS of TOO LITTLE LIGHT? (2)

1.) Die and fall off

2.) Plant dies

11

During periods of TOO LITTLE LIGHT, CARBOHYDRATES can be used for ____________ but only to a point.

Cellular Respiration

12

These are NUTRIENTS that ABSORBED FROM the SOIL.

Mineral Nutrients

13

This is a type of MINERAL NUTRIENT that is required in LARGE quantities.

Macronutrients

14

These are a type of MINERAL NUTRIENTS that are required in SMALL quantities.

Micronutrients

15

This is a method of GROWING PLANTS using MINERAL NUTRIENTS IN WATER.

Hydroponics

16

True or False: The method of HYDROPONICS raises plants in aqueous solution containing unknown quantities of solution.

FALSE, The method of HYDROPONICS raises plants in aqueous solution containing KNOWN QUANTITIES OF SOLUTION.

17

True or False: HYDROPONICS uses the same NUTRIENT COMPOSITION of solution.

FALSE, HYDROPONICS is VARIED in NUTRIENT COMPOSITION of solution.

18

What 2 factors do DEFICIENCY SYMPTOMS DEPEND UPON?

1.) Function

2.) Mobility

19

This DEFICIENCY SYMPTOM is characterized by PURPLE streaks on the OUTER EDGE of the leaf (NEAR VEINS). They are smaller in size and have a DARK GREEN COLOR.

Phosphate Deficiency

20

This DEFICIENCY SYMPTOM is characterized by YELLOW/ORANGE streaks on the OUTER EDGE of the leaf. They are smaller in size, have WEAK stems, WILTED appearance and NECROTIC SPOTS.

Potassium Deficiency

21

This DEFICIENCY SYMPTOM is characterized by YELLOW/ORANGE streaks INSIDE of the leaf (MORE THAN younger plants). They are smaller in size.

Nitrogen Deficiency

22

NUTRIENTS are SENT to GROWING TISSUE by way of __________.

Phloem

23

True or False: GROWING tissue that REQUIRE NUTRIENTS can obtain them from breaking down old tissue.

TRUE, GROWING tissue that REQUIRE NUTRIENTS can obtain them from breaking down OLD TISSUE.

24

True or False: all nutrients are PHLOEM MOBILE.

FALSE, NOT ALL NUTRIENTS are PHLOEM MOBILE

25

In PHLOEM ______ NUTRIENTS, deficiency symptoms show up in OLD TISSUE FIRST.

Phloem MOBILE Nutrients

26

In PHLOEM _________ NUTRIENTS, deficiency symptoms show up in YOUNG TISSUE FIRST.

Phloem IMMOBILE Nutrients
