meiosis
process that produces haploid cells
Parts of a pistil
ovary, and stigma
How to flowers that lack showy petals, nectar, and odors get pollinated?
by wind
What’s part of the plant are necessary for pollination?
anther, stigma & pollen
Order of plant reproduction
pollination, fertilization, seed development
cotyledon
a form of stored food in a seed
flower
a reproductive organ found on some plants
pistil
the female reproductive part of a flower
anther
the saclike structure that produces pollen
stigma
the tip of the pistil that receives the pollen
pollen
contains the male gametes of a flower
pollen tube
tube that grows down the style and into the ovary
seed
a mature ovule containing an embryo plant
filament
is attached to the anther
style
the stalk between ovary and stigma
diploid
organisms that have 2 of every kind of chromosome
nectar
a sugary liquid that attracts pollinators
Which reproduction, asexual or sexual reproduction, provides little genetic variation?
asexual
horticulturist
someone who works with growing, harvesting, processing, or shipping vegetables, fruits, flowers, or ornamental plants.
sepals
leaflike structures found at the bast of many flowers
How does the stigma retain the pollen?
Because it’s usually sticky
Types of asexual reproduction in plants
runners, plantlets, root sprouts, leaf cuttings, stem cuttings, and potato eyes.
gametes
a mature male or female germ cell usually possessing a haploid chromosome set and capable of initiating formation of a new diploid individual by fusion with a gamete of the opposite sex
Why are flowers that are pollinated by the wind, usually produce greater quantities of pollen than flowers pollinated by birds, insects, or bats?
Pollen grains of wind-pollinated flowers are produced in large quantities to make sure that at least some pollen grains reach the stigmas of other flowers and successful pollination takes place as many pollen grains are wasted. Stigma is large and feathery to catch the wind pollen grains.
Why are hazelnuts and acorns considered a fruit?
Because they are the fruit of the tree. They contain the seeds that can grow new trees, and falling to the ground is part of the tree's lifecycle – this is how it reproduces. Having reached the ground, the hazelnuts and acorns can grow into new trees or be carried off to new locations by wildlife.
How can animals that eats seeds be beneficial for tree growth?
The can poop out the seeds and grow new plants!
What part of the flower will become the fruit?
the ovary
How can you determine how many seeds will develop from a flower?
However many ovules it has, that’s how many seeds will form.
haploid
specials cells with only ONE of each kind of chromosome normally found in that organism
genetic variation
getting different genes from each of the parents (example: different nose shapes)
receptacle
the base of a flower
petals
often provide the color and design of the flower and help to attract the insects and animals that aid in pollinating the flower.
pollination
the process of transferring pollen from an anther to a stigma
ovary
the swollen area at the bottom of the pistil.
ovules
located inside the ovary, it contains the eggs (the female gametes) of the plant
monocot
a seed that contains just ONE cotyledon
embryo (a fertilized egg)
a tiny plant
As the ovary grows, what does it develop into?
a fruit
Do the chromosomes of plants usually occur in pairs just as those of animals do?
Yes
What is the main funcation of gametes?
to transfer or recieve chromosomes during sexual reproduction
How do flower petals help a flowering plant reproduce?
They attract pollinators
Where, specifically, is pollen produced?
in the anthers of the stamens
Which occurs first, fertilization or pollination?
pollination
Like a plant’s fruit, what does spiritual fruit reveal about the person who produces it?
Our attitudes and daily choices reveal our spiritual identity, just as fruit reveals the identity of the plant that produced it.
asexual reproduction
plant reproduction that does not involve gametes
Why is there little genetic variation in asexual reproduction?
Because the plant’s genes are identical to the parents. It doesn’t get genes from both.
runners
thin stems
plantlets
complete plants, grown off runners, that can grow and mature if placed in soil
root sprouts
is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub.
leaf cutting
a leaf that was cut and begins to grow roots
How could the genes of 2 trees that grew from separate root sprouts be identical?
It had the same parent.
Are the reproductive cells of an organism haploid or diplod?
haploid
Which part of a flower is the male part?
the stamen (anther and filament combine to make the stamen)
3 main parts of a seed
an embryo, stored food (cotyledon), and a protective coat
fruit
a ripened or mature ovary; Both develop from ovaries of flowers.
nectar
a substance that most directly aid in pollination
Male is to pollen as female is to…
ovule
Runners are usually assoicated with
plantlets
