Answer 2

-Accounts for roughly 90% of living plants
-Widely range in size and form
-Have magnoliids; avocados, pepper plants
-Have eudicots; cabbage, daisies, trees
-have monocots; rice, corn, wheat

Question 3

What are the characteristics of Monocots?

Answer 3

-have 1 cotyledon
-have parallel veins
-scattered vascular tissue
-fibrous root system (no main root)
-pollen grain with 1 opening
-flowers are typically in sets of 3

Question 4

What are some characteristics of Eudicots?

Answer 4

-2 cotyledons
-netlike veins
-vascular tissue is arranged in a ring
-taproot (has a main root)
-Pollen grain with 3 openings
-flowers are typically in sets of 4 or 5

Question 5

Stamen

Answer 5

The male part of the flower made up of 2 parts, the filament and the anther

Question 6

Filament

Answer 6

Supports the reproductive organ, the anther

Question 7

Anther

Answer 7

the reproductive organ of the plant, main job is to produce pollen

Question 8

Carpel

Answer 8

The female part of the plant, consists of the stigma, style, ovary, and ovule

Question 9

Stigma

Answer 9

Sticky tip of the style that captures pollen grains

Question 10

Style

Answer 10

Stalk that supports the stigma and connects it to the ovary so fertilization can occur.

Question 11

Pollen tube

Answer 11

forms within the style and carries pollen grains (male sperm) towards the ovules (female eggs)

Question 12

Ovary

Answer 12

Holds the ovules

Question 13

Ovules

Answer 13

creates megaspores (female eggs)

Question 14

Petals

Answer 14

Brightly colored used to attract pollinators

Question 15

Sepals

Answer 15

Base leaves of the flower that supports the petals

Question 16

Unique characteristic of Pollen

Answer 16

Pollen has a hard shell and therefore can fossilize in the fossil record

Question 17

Norman Borlaug

Answer 17

-Started working with the idea of genetically modified foods to increase yield
-Argues that we have to expand and increase our produce production
-Food security and food distribution is the main challenge of food security

Question 18

Bioprospecting

Answer 18

Idea that we can go out in nature and begin to discover used of plants that will directly help the human species throughout the use of medical applications.

This has concern with regulation so that is is not over harvested and driven towards extinction. (Eucalyptus tree is used for a throat soother)

Question 19

What is the Green Revolution?

Answer 19

The emergency of new varieties of crops that allowed us to have 3,000 edible species and 200 planted as vital crops. This helps increase yield to support the human population.

Question 20

Co-evolution

Answer 20

Refers to two or more species jointly evolving because of their close ecological interactions

Question 21

Co-evolution arms race

Answer 21

an ongoing struggle between competing sets of co-evolving species, genes, phenotypic and behavioral traits that develop escalating adaptations and counter-adaptations against each other

Angiosperms coevolution with insects, bats, small mammals, birds and pollination for angiosperms.

Question 22

Symbiotic co-evolution

Answer 22

When both species are favored and a favorable relationship is develop between the two.
