types of flowers
Which type of flower has four main basic parts of the flower
Complete flower
Transfer from anther to stigma of a pistil
Pollination
What are three main parts of a seed
Embryo plant,endosperm,seed coat
name at least two or three simple fruits
Drupes,pomes,achenes,nuts,berries,samaras, legumes, and grains
How does pollen get from the anther to the stigma?
Insects/pollination
Pollen can be transferred by insects, birds, wind, water, or other animals. This process is called pollination.
Which type of flower Lacks one or more of these four basic flower parts?
Incomplete
A sweet tasting watery liquid produced by plants
Nectar
each embryo consists of a plumule, radicle, and ______
Cotyledons
Explain the difference between multiple/simple fruits
Simple: forms from one flower that only has one pistil
multiple: form from several flowers
Why might some flowers have nectar?
Nectar provides food for pollinators, encouraging them to visit the flowerand transfer pollen.
Staminate
Explain the difference between self pollination/cross pollination
Self pollination: pollination occurs within the same flower
cross pollination: pollination occurs when the pollen from another plant is transfered to the stigma of a flower on another plant
Is dormancy part of germination or fertilization?
extra points(300) if u tell me the meaning of dormancy
Dormancy : a period of inactivity which helps prevents seeds from sprouting when conditions are unfavorable for the growth of young plants
True or false
In fact, all fruits are considered to be either fleshy or dry
True
Explain the function of the the anther
Any plant on which both staminate and pistillate flowers are produced in the same plant
Monoecious
True or false
To a botanist, a ripened ovary is called a fruit when it is sweet and whether it is edible or not
True or false
the embryo obtains energy for its rapid growth by “ burning” the stored food in its cotyledons by the process of air respiration
False
Explain what an agent dispersal
Seed dispersal in which an outside agent carries the seed
Why are brightly colored flower and strong scented leaves helpful to some flowers?
They help attract pollinators increasing the chance
What is the meaning of a dioecious flower?
Having staminate and pistillate flowers borne by seperate plants
Fill in the blank!
one of the sperm cells unites with the egg cell, forming the embryo, the other sperm fuses with cells called ________ to form endosperm
Polar nuclei
True or false
most of the food stored in the cotyledon is in the form of sucrose
false
Give me examples of mechanical dispersal
Violets,witchhazel,jewelweeds
A nutritional tissue that surrounds the fertilized egg and provides nourishment to the growing embryo
Endosperm
