flowering plants study guide

germination

the development of a plant from a seed or spore after a period of dormancy

endosperm

the part of a seed that acts as food store for the developing plant

cotyledons

the first leaves developed by embryo (fertilized egg) within a seed

monocot

means one thing

dicot

means two things

pollination

when pollen from an anther comes in contact with the sticky stigma of a pistil

fertilization

when a male sperm and a female egg unite

seed dispersal

the movement or transport of seeds away from the parent plant

pistil

female structure

stigma

the top of the pistil

style

a structure that supports the stigma

ovary

the hollow base of the carpel of a flower containing one or more ovules

ovules

the part of the ovary of seed plants that contains the female germ cell and after fertilization becomes the seed

stamen

the male fertilization organ of a flower typically consisting of a pollen - containing anther and a filament

pollen

a yellow powdery substance consisting of microscopic grains

anther

the part of a stamen that contains pollen

filament

the slender part of a stamen that supports the anther

petal

the segments of the corolla of a flower which are modified leaves that are typically colored

sepal

each of the parts of the calyx of a flower, enclosing the petals and typically green and leaf like

seed

a flowering plants unit of reproduction

fruit

of a tree or other plant produce fruit... typically at a specified time

stomata

found in epidermis of leaf or stem

transpiration

a way of getting one place to another

what does 20-20-20 refer to on the fertilizer we use to water our fast plants

equal portions of macronutrients, nitrogen phosphorous, and potassium

how do water and minerals get into the plant

root stem

what are at least 3 ways Wisconsin Plants are unique and useful in class rooms

1. go through life cycle in 6 weeks

2. dont take up space

3. produce large number of fertile seeds

what is the difference between cotyledons and true leaves in flowering plants

cotyledons is present before germination

what do ovules and ovary grow into in a flowering plant

ovary grows into a fruit

ovule turns into a seed

RESPONSE:

what are at least 3 differences between monocots and dicots

1. monocot has one and dicot has 2

2. dicots have net like veins, monocots have parallel veins

3. monocots have tubes for carrying water, dicots have minerals spread in stem

3 examples of flowering plants that are monocots

tullips

lillies

corn

3 examples of flowering plants that are dicots

roses

apples

cherries

difference between self-pollination and cross-pollination

self pollination is the transfer of pollen grains from anther to stigma on the same flower.

cross pollination brings pollen from one flower to a genetically different flower

how do flowering plants reproduce asexually

bulbs and cutting

adavantages of asexual reproduction?

only need one parent... quicker

how do flowering plants reproduce sexually

pollination and fertilization

advantage of sexual reproduction?

genetic diversity

what are some ways that flowering plants encourage pollination?

visits by potential pollinators, colors, and scents
