Biology Module 15 Part 2

Front 1

Translocation-

Back 1

the process by which organic substances move through the phloem of a plant.

Front 2

Xylem-

Back 2

cells die when they mature. They arejust tubes

Front 3

Phloem-

Back 3

alive cells; because they expend energyto guide the flow of organic molecules through the plant. Actively participatein translocation.

Front 4

As aplant develops, it grows. Much of its growth happens in the______________ tissue.

Back 4

meristematic

Front 5

Hormones-

Back 5

chemicals that circulate throughoutmulticellular organisms, regulating cellular processes by interacting withspecifically targeted cells

Front 6

5 groups of plant hormones:

Back 6

auxins, Gibberellins,Thigmotropism, Cytokinins, Abscisic , Ethylene

Front 7

auxins-

Back 7

regulate development of cells. It affects the length of the stem.

Front 8

Gibberellins-

Back 8

affect the mitosis rate, also induces seeds to germinate.

Front 9

Thigmotropism

Back 9

growth response to touch

Front 10

Phototropism

Back 10

growth in response to light

Front 11

Gravitropism

Back 11

growth response to gravity

Front 12

Insectivorous plants are sometimes called _____________ plants

Back 12

carnivorous

Front 13

Why do insectivorous plants catch insects?

Back 13

Becausethey need other raw materials to live. They have been designed to live in soilsthat have few or no raw materials.

Front 14

One ofthe most important raw material a plant needs for biosynthesis is____________.

Back 14

nitrogen

Front 15

Vegetative reproduction is____________reproduction

Back 15

asexual

Front 16

Give examples of vegetative reproduction

Back 16

runners, plantlets, tubers (potatoes), regular stems, leaves, and grafting.

Front 17

Flowering Plants in Phylum Anthophyta is an example of _____________ reproduction

Back 17

Sexual

Front 18

The _____________ contains the reproductive organs and allow plants to reproduce sexually in Phylum Anthrophyta

Back 18

flower

Front 19

Pedicel- - >

Back 19

stem that holds the flower

Front 20

sepals

Back 20

green leaf-like structures above the pedicel. Designed to protect the reproductive organs as they form.

Front 21

petals-

Back 21

leaf-like structures above the sepals.

Front 22

stamens

Back 22

male reproductive organs. Have long filaments to support the anther.

Front 23

Anther

Back 23

The anther releases the pollen grains

Front 24

Pollengrains

Back 24

contain haploid cells that function as sperm.

Front 25

carpel-

Back 25

female reproductive organs (also known as the pistil)

Front 26

The stigma is _________________________________________.

Back 26

covered with a sticky substance designed to catch the pollen grains.

Front 27

The style is an extension of the __________designed to hold the stigma where it can be exposed to the pollen grains.

Back 27

ovary

Front 28

Ovary contains the___________________________

Back 28

ovule that holds the embryo sac.

Front 29

Embryo sac contains the ____________________________

Back 29

egg, where the seeds develops.

Front 30

What are the two kinds of flower classes?

Back 30

perfect and imperfect

Front 31

Perfectflowers-

Back 31

flowers with both stamens and carpels.

Front 32

Imperfect flowers-

Back 32

flowers with either stamens or carpels, but not both.

Front 33

Reproductive process We know that ____________ make pollen grains and carpels make the embryo sac.

Back 33

stamens

Front 34

Carpels make the ____________ sac

Back 34

embryo

Front 35

Zygote is a ________ cell

Back 35

diploid

Front 36

Onceour fertilization takes place, the will __________ and the ________develop bymitosis.

Back 36

endosperm and the zygote

Front 37

The _______________ develops into the food source for the developing zygote.

Back 37

endosperm

Front 38

The _________ _________ for the developing zygote is the cotyledons.

Back 38

food source

Front 39

Seed-

Back 39

an ovule with a protective coating, encasing a mature plant embryo and a nutrient source.

Front 40

Fruit-

Back 40

a mature ovary that contains seed or seeds.

Front 41

The purpose of fruit is ______________________________________________________________________

Back 41

for the dispersal of the seed away from the parent.
