Plant Bio Quiz #4

Front 1

What is the largest group in the plant kingdom?

Back 1

The angiosperms OR flowering plants.

Front 2

What are the reproductive parts of the flower?

Back 2

The stamens and the pistil(s).

Front 3

What does the stamen usually consist of?

Back 3

A stalk-like filament and a terminally enlarged structure called the anther.

Front 4

What does the anther usually have?

Back 4

Four pollen sacs.

Front 5

Pollen Mother Cells (PMC's)

Back 5

Form in the center of each pollen sac and undergo meiosis to form the pollen.

Front 6

Each pollen grain is a microspore and develops into a what?

Back 6

Male Gametophyte

Front 7

What cell divides to give rise to two sperm cells?

Back 7

Generative Cell

Front 8

Pistil

Back 8

The female part of the life-cycle and represents a highly modified leaf.

Front 9

Stigma

Back 9

A terminal pollen-receptive structure.

Front 10

Style

Back 10

A long stalk-like structure below the stigma.

Front 11

Ovary

Back 11

A swollen basal structure that contains the ovule(s) which later develops into the fruit.

Front 12

Megaspore Mother Cell

Back 12

The cell that undergoes meiosis to develop into four megaspores.

Front 13

Embryo-Sac

Back 13

Nothing more than the highly reduced female gametophyte of the flowering plants.

Front 14

The mature angiosperm female gametophyte consists of what 7 cells?

Back 14

The egg, two synergids, three antipodals, and a large central cell with two so-called polar nuclei.

Front 15

Double Fertilization

Back 15

The second sperm unites with the two polar nuclei of the central cell of the female gametophyte to form typically a triploid tissue called the endosperm that nourishes the developing embryo.

Front 16

What are the two main groups of angiosperms?

Back 16

Dicots and Monocots.

Front 17

Characteristics of Dicots...

Back 17

Have embryos with two cotyledons, reticulate-veined leaves, may be woody, have a typical vascular cambium, have vascular bundles in a ring in their stems, a taproot system, flower parts in 5's or 4's, and 3-furrowed pollen.

Front 18

Characteristics of Monocots...

Back 18

Have embryos with one cotyledon, parallel-veined leaves, almost always herbaceous, never have a true vascular cambium, scattered vascular bundles, fibrous root system, flower parts in 3's, and 1-furrowed pollen grains.

Front 19

What does a complete flower consist of?

Back 19

Sepals, Petals, Stamens, and Pistil(s).

Front 20

Together the calyx and the corolla are known as the what?

Back 20

Perianth

Front 21

What does the Perianth do?

Back 21

Protects the immature flower bud and attracts animal pollinators.

Front 22

What is the stamen?

Back 22

The male organ, producing pollen, and contains the male gametophyte of the flowering plant.

Front 23

Simple Pistil

Back 23

Made up of one leaf homologue.

Front 24

Compound Pistil

Back 24

Represents the fusion of two or more leaf homologues to form a single compound structure.

Front 25

Polypetalous

Back 25

With seperate petals.

Front 26

Sympetalous

Back 26

With fused petals.

Front 27

Apetalous

Back 27

Lacking petals.

Front 28

Bisexual

Back 28

With both stamens and pistil/pistils.

Front 29

Unisexual

Back 29

With two types of flowers, one staminate with stamens and no pistils, the other pistillate with pistil/pistils and no stamens.

Front 30

Are angiosperms mostly animal-pollinated or abiotic pollination?

Back 30

animal-pollinated

Front 31

Animal-pollinated

Back 31

Insects being the most important animal pollinators, as are birds and bats in the tropics.

Front 32

Abiotic pollination

Back 32

By some inanimate force, including wind or water.

Front 33

Fruit

Back 33

The mature product of the ovary of an angiosperm pistil.

Front 34

Accessory Fruit

Back 34

Enlarged, fleshy receptacle.

Front 35

Simple Fruit

Back 35

Fruit is the product a single pistil.

Front 36

Compound Fruit

Back 36

Of more than one pistil.

Front 37

Aggregate Fruit

Back 37

Front 38

Multiple Fruit

Back 38

Several flowers fused together.
