Where are these chemicals made in a flower?
These carbohydrates, or simple sugars, are produced by the nectaries.
In spruce trees _____________ produce pollen.
Staminate Cones
What is the name of the chemical reaction that produces the chemical components of nectar?
Photosynthesis.
Which part of the flower will pollen stick to in order to complete pollenation?
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.
Extra Credit! Why should I care about flowers? Well, remember, there is only one reason to study science, and that is to make money. How much money does the US floral industry produce annually?
$16 Billion - as cited from Cision PR Newswire (2018 - 2023 forecast)
After looking at this diagram, can you explain where the male gametophyte develops and reaches maturity?
The male gametophyte develops and reaches maturity in an immature anther.
In this photograph, which anatomical structure is considered to be the style?
The style is the long, slender tube in between the ovary and the stigma.
In this photograph, where are the flowers' sepals?
Sepals are the outer parts of the flower (often green and leaf-like) that enclose and protect the pedals and other parts of a developing flower.
In this photograph, the bee is more than likely attracted to the flower because of the _____________ and ____________.
The bee is attracted to the color of the pedals and the nectar the flower produces.
This pollen grain is ________________.
Germinating. I would also accept growing a pollen tube.
This is ________________. HINT! The words "pumpkin", "plant", or "vine" are NOT correct answers.
a fruit that usee to be the ovary of a flower. Larsen will also accept "future pie" or "future Jack-O-Lantern".
Behold the lovely pumpkin flower. What will the ovary eventually become.
The fruit.
Plant growth is possible thanks to a cellular process called ______________.
Mitosis or cell division.
This is ________________.
A stigma impregnated with pollen grains.
As you can see, these are pine cones. Which one is staminate? Which one is ovulate?
The staminate cones are smaller than the ovulet cones.
Where is the ovary in this photograph?
The ovary is the oval-shaped green object above the recepticle and below the style.
What Phylum does the organism in the photograph belong to and why?
Flowering plants are Angiosperms. Their Phylum is Anthophyta or Angiospermae
Which structure, in this photograph, is responsible for making pollen?
The anther makes pollen. The stamen is made of an anther which is supported by a slender fillament.
Does the male or female gametophyte "live" here?
The ovule is where you will find the female gametophyte.
Observe the obvules. Will they become fruit or seeds.
Fertilized ovules will develope into seeds.
True or False. The filament produces pollen.
False. The fillaments support the anthers. It is the anthers that make pollen.
In this photograph, where is the flower's carpel?
The carpel is located inside the pedals. Carpels are the female reproductive structures.
What is the name of the cellular process that divides the number of chromosomes in a cell by half? Where does this process take place?
Meisosis divides the number of chromosomes in a cell in half. This takes place in the anther and produces a pollen grain.
In this photograph, which used to be the ovule and which used to be the ovary?
When mature, the ovary is a fruit and the ovule is a seed.
