Term
2 characteristics of an Angiosperm
Definition
Produces flowers
Seeds enclosed in fruits
Term
male reproductive parts are called. . .
Definition
stamens
Term
female reproductive parts are called. . .
Definition
pistil
Term
A sepal does what?
Definition
A sepal protects a developing flower
Term
The petal's function is to. . .
Definition
Attract pollinators
Term
[image]
Definition
a-stigma
b-anther
c-petal
d-sepal
e-ovary
f-stem
g-ovule
h-filament
Term
what falls on a flower's stigma that helps it reproduce?
Definition
Pollen
Term
What joins together in a flowers ovule?
Definition
the sperm cell and the egg cell
Term
True or false- Some angiosperms rely on wind for reproduction.
Definition
True
Term
How do animals help to pollinate flowers?
Definition
A sugary food called nectar, is located inside of a flower. When a animal enters a flowers to drink/eat nectar, the pollen sticks to the pollinator and when the animal sucks another flower's nectar, the pollen from the other flower sticks to the stigmas of the other flower.
Term
Describe a monocot.
Definition
a monocot's petals are in groups of threes, the veins of its leaves are parallel, it has one cotyledon, and many scattered roots.
Term
where does the embryo in a seed get food?
Definition
The cotyledon or seed leaf.
Term
A plant has 12 petals. Is it possible to tell that the plant is a monocot or dicot with only this information? Why?
Definition
12 is a common factor of 3 and 4, it could be a monocot or a dicot. You would have to use another part of the plant.
Term
Roses, violets and oaks are examples of these.
Definition
dicots.
Term
Five things people use plants for.
Definition
Oxygen and breathing
Food
Medicine
Food
Shelter
Term
one example of a medicine that comes from an angiosperm.
Definition
Digitalis
Term
Describe the process of embryo formation in an angiosperm.
Definition
When pollen sticks to a stigma the pollen goes through the pollen tube and drills a hole into the ovule and then the sperm cell and egg cell combine and an embryo forms in the seed.
Term
What are the 2 phylum of plants
Definition
vascular and non-vascular
Term
Who were the first plants
Definition
Non vascular
Term
What do the xylem and phloem do?
Definition
The xylem brings water up and the phloem sugar down
Term
What is the main difference between Gymnosperms and Angiosperms?
Definition
Angiosperms have flowers and fruit. Gymnosperms have naked seeds.
Term
What is Chloroplast?
Definition
Leaf cells that convert stuff into sugar.
Term
what is chlorophyll?
Definition
pigment that absorbs sunlight (green)
Term
What is the chemical formula for photosynthesis?
Definition
Water+Carbon dioxide+sunlight= sugar & oxygen
Term
What is water dispersal and why is it important?
Definition
Water dispersal is how seeds move from one place to another through water. If seeds drop to the ground directly under the parent plant they will not have the room and nutrients they will need to grow.
Term
What is wind dispersal and why is it important?
Definition
Wind dispersal is when seeds and/or small fruits are carried by the wind. When they land they plant themselves, maybe colonizing mountains at a time. Hundreds of plants use this method. Most plans considered to be weeds disperse their seeds through wind.
Term
What is pollination and why is it important?
Definition
A pollinator takes the pollen from a stamen on a male flower and lands on a female flower. Then, the pollen goes down the pistil to the ovary, and fertilizes the eggs. Pollination leads to the creation of new seeds. FERTILIZES the flower so the seed can be produced. (sperm and egg mix DNA.)
Term
What is self pollination?
Definition
A flower uses its own pollen and ovules to make a new seed.
Term
What is cross pollination?
Definition
Two flowers of the SAME SPECIES exchange pollen to the other flower by pollinators.
Term
What does a plant need to grow?
Definition
Sunlight, carbon dioxide, water and room to grow.
Term
How to propagate a plant with roots?
Definition
Choose the plants you wish to grow from a cutting. Using sharp garden secateurs (pruners), snip off shoots from the plant. Strip a half to two thirds of leaves from the lower part of the cutting and remove flower buds because they will suck the nutrition out that the plant needs during the time it is growing new roots. Treat the cutting. Start your cutting in sand, soil, or even just water. Keep the cutting moist, but not over watered (try a mister). Transplant your cuttings to their final growing spot.
Term
What is a gymnosperms life cycle?
Definition
Male and female cones- pollen mixes with egg (wind)
Seed develops
Wind takes seed to a new place
Seed germination
Term
Pistil=
Definition
female reproductive part that contains the ovules/future seeds
Term
Stigma=
Definition
Sticky top of the pistil
Term
Sepal=
Definition
bottom "leaves" of the flower, they protect the little bud then open up
Term
Stamen=
Definition
male reproductive part that produces pollen
Term
Anther=
Definition
part with the pollen
Term
Filament=
Definition
attaches the anther to the stem of the flower
Term
petals=
Definition
have special colors that attract pollinators to the pollen to reproduce.
Term
What does Gymnosperm mean?
Definition
naked seed
Term
What are the most well known gymnosperms?
Definition
Pine trees
Term
What are female cones called and why?
Definition
Seed cones because the hold the seed.
Term
True or false- the seed takes less than a month to mature
Definition
false
Term
Do they use the same life cycle as other plants. true or false?
Definition
True
Term
What are cones on conifer trees
Definition
Scales
Term
What does a male cone produce?
Definition
Pollen
Term
What does a female cone reproduce?
Definition
Eggs
