Explore the Wonders of Flowering Plants
Test your knowledge about flowering plants and their fascinating reproductive processes! This quiz covers various aspects of plant biology, from fertilization to seed dispersal.
Whether you are a student, teacher, or simply a plant enthusiast, you'll find questions that challenge your understanding. Key topics include:
- Double fertilization
- Seed structures
- Tissue culture advantages
- Life cycles of angiosperms
Double fertilization in an angiosperm produces
A diploid zygote and a haploid polar nucleus.
A diploid zygote and a diploid endosperm.
A diploid embryo and a triploid zygote.
A triploid embryo and a diploid endosperm.
A diploid zygote and a triploid endosperm.
Fertilization in flowering plants occurs
On the stigma.
In the style.
In the ovule.
In the anther.
In the endosperm.
Which of the following is a vegetative structure?
Stem
Sepal
Petal
Stamen
Carpel
How many nuclei are present inside a pollen grain?
None
One
Two
Three
Four
A pea is actually a seed.
True
False
The banana can only be produced through tissue culture.
True
False
Which of the following statement is true about the life cycle of flowering plants?
The sporophyte is diploid.
The sporophyte produces two different types of spores.
The male gametophyte is the pollen grain.
The female gametophyte is retained within the body of the sporophyte parent generation.
All of the answer choices are true.
You are examining a seed with tiny white plumes attached to it. How is this type of seed most likely dispersed?
By animals who eat it
By floating on water
By the wind
By attaching to the fur of animals
By bursting forth from the seed pod
The megaspore divides mitotically, resulting in a female gametophyte or embryo sac that differentiates into an egg and a central cell with two nuclei called the
Generative cell.
Pollen grain.
Microspores.
Endosperm.
Polar nuclei.
What flower mechanism would help prevent pollination by a foreign plant species?
A pollen tube only grows inside the style of its own species.
The stigma is sticky mainly to its own species of pollen.
The timing of flowering keeps pollinators moving among a limited number of species.
Flowers attract a small number of specialized pollinators and, therefore, pollen is not spread equally to all available species of flowers.
All of the answer choices help prevent pollination by a foreign species
Which of the following would be considered a dry fruit?
One that doesn't split open
One derived from a simple ovary
One derived from the receptacle and not the ovary
One derived from several individual ovaries
One derived from many different carpels
How are potato plants propagated?
By "eyes" (a bud)
By runners
By pollen
By flowers
By protoplasts
The male gametophyte in flowering plants will be found within the
Carpel.
Ovary.
Sepal.
Filament.
Pollen grain.
Which of the following is an advantage of tissue culture?
Plant tissue can be used to produce medicines such as digitoxin and other products for the treatment of human disease.
Tissue culture allows the production of healthier plant varieties.
Many botanical gardens and universities use tissue culture for plant conservation.
Tissue culture helps maintain plants that are disease-free.
All of the answer choices are advantages of tissue culture
When you eat an apple, the core left over is the ovary.
True
False
