Lab 4: Angiosperm Structure and Function

Question 1

Angiosperms

Answer 1

A flowering plant, which forms seeds inside a protective chamber called an ovary.

A basic angiosperm body is composed of a root and a shoot.
Division Anthophyta

Question 2

Shoot system

Answer 2

The aerial (above ground) portion of a plant body, consisting of stems, leaves, and (in angiosperms) flowers.

Question 3

2 Major Groups of Angiosperms

Answer 3

Eudicots and Monocots

Question 4

Eudicot Characteristics

Answer 4

• 2 Cotyledons
• Net-like Veins in Leaves
• Flower Petals come in Multiples of 4 or 5
• Stem Vascular System is Ring-Shaped
• Root Vascular System is in a cylinder in the center of the root
• Includes trees
• Wood (the xylem part)

Question 5

Monocots Characteristics

Answer 5

• 1 Cotyledon
• Parallel Veins in Leaves
• Flower Petals come in Multiples of 3
• Stem Vascular System is Scattered
• Root Vascular System is Ring-Shaped
• Includes shrubs, grasses, corn

Question 6

Flowers

Answer 6

The reproductive part of angiosperms.

Modified leaves.

Question 7

Modified leaves

Answer 7

Petals, sepals, stamens, pistils

Question 8

Sepals

Answer 8

Protect the developing bud.

Sterile.

Question 9

Petals

Answer 9

Sterile.

Question 10

Reproductive parts of the flower:

Answer 10

Female: Pistil
Male: Stamen

Question 11

Pistil

Gynoecium

Answer 11

Female part of the flower.

Consists of the ovary, ovules, style, and stigma.

Question 12

Stamen

Androecium

Answer 12

Male part of the flower.

The pollen-producing reproductive organ of a flower, consisting of an anther and a filament.

Question 13

Pollination

Answer 13

The transfer of pollen to the part of a seed plant containing the ovules, a process required for fertilization.

Question 14

stigma

Answer 14

The female sticky part of a flower, which receives pollen grains.

Question 15

primary growth

Answer 15

Growth produced by apical meristems, lengthening stems and roots.

Question 16

secondary growth

Answer 16

Growth produced by lateral meristems, thickening the roots and shoots of woody plants.

Question 17

lateral meristem

Answer 17

A meristem that thickens the roots and shoots of woody plants. The vascular cambium and cork cambium are lateral meristems.

Question 18

vascular cambium

Answer 18

A cylinder of meristematic tissue in woody plants that adds layers of secondary vascular tissue called secondary xylem (wood) and secondary phloem.

Question 19

cork cambium

Answer 19

A cylinder of meristematic tissue in woody plants that replaces the epidermis with thicker, tougher cork cells.

Question 20

carpel

Answer 20

The ovule-producing reproductive organ of a flower, consisting of the stigma, style, and ovary (i.e., the pistil).

Question 21

node

Answer 21

A point along the stem of a plant at which leaves are attached.

Question 22

pollen

Answer 22

In seed plants, a structure consisting of the male gametophyte enclosed within a pollen wall.
