Plant reproduction
What is asexual reproduction?
A portion of one plant develops into a new and identical plant to its parent plant.
What is sexual reproduction?
A plants sperm combines with egg to make
What is Alternation of Generations?
When the plants life cycleSwitched between diploid and haploid generations
Define diploid
Full number of chromosomes
Define haploid
Half number of chromosomes
Note: there will not be any questions about seedless plants on the quiz :) Thanks because i would be cooked if there was
What are pollen grains?
They form a male reproductive tissue
What do pollen grains produce?
Sperm cells
How are pollen grains carried to the female reproductive structure? (the slides give several ways)
Wind, animals, gravity, water
What are ovules?
Where the haploid egg develops
What does the ovule produce?
embryo
What is a zygote?
A fertilized embryo
What is an embryo?
Immature diploid plant
What is a seed?
Food supply
What is the reproductive structure of gymnosperms?
Cones
Seeds are part of which cone (male or female)?
Female
Pollen is part of which cone (male or female)?
Male
What is the reproductive organ of angiosperms?
Stamen
What is the male reproductive structure of a flower?
Stamen
What are the two parts of the male structure?
Stamen and anther
What do each of the parts do?
They help with reproduction
What is the female reproductive structure of a flower?
Pistil
What are the three parts of the female structure?
Stigma, style, and ovary
What do each of the parts do?
Stigma: Top of the pistil where pollen lands
Style: The tube under the stigma
Ovary: Base of the style
Be able to label the parts of a flower (see the diagram from our gizmos activity worksheet)
Ok
What is pollination?
The process of pollen traveling to the sticky stigma
What is fertilization?
When pollen enters the ovule
What happens to the fertilized egg after fertilization?
It becomes a seed
What sometimes is produced from angiosperms that contains the seeds?
Fruits
List 3 examples of fruits.
Strawberry, banana, and tomato
How do fruits help with seed dispersal?
Animals can spread the seeds
