What is sexual reproduction in plants?
The process by which plants produce offspring through the combination of male and female gametes.
True or False: In sexual reproduction, plants rely solely on asexual methods.
False
What are gametes in the context of plant reproduction?
Reproductive cells that unite during fertilization to form a new organism.
Fill in the blank: The male gamete in flowering plants is called __________.
pollen
What is the role of the ovule in plant reproduction?
It contains the female gamete and develops into a seed after fertilization.
What is pollination?
The transfer of pollen from the male anther to the female stigma of a flower.
Multiple Choice: Which of the following is a method of pollination? A) Wind B) Water C) Insects D) All of the above
D) All of the above
What is fertilization in plants?
The fusion of male and female gametes to form a zygote.
True or False: All plants reproduce sexually.
False
What is a flower’s main function in sexual reproduction?
To facilitate the process of pollination and fertilization.
Fill in the blank: The part of the flower that produces pollen is called the __________.
anther
What is the function of the stigma in a flower?
To receive pollen during the pollination process.
Multiple Choice: Which of the following structures develops into fruit after fertilization? A) Ovule B) Ovary C) Stamen D) Petal
B) Ovary
What is the difference between self-pollination and cross-pollination?
Self-pollination occurs when pollen from the same flower fertilizes its ovule; cross-pollination involves pollen from a different flower.
Fill in the blank: The zygote develops into a __________ after fertilization.
seed
What is the significance of genetic variation in sexual reproduction?
It increases the adaptability and survival of offspring in changing environments.
True or False: Sexual reproduction in plants can occur without pollinators.
True
What is double fertilization in angiosperms?
A process where one sperm fertilizes the egg to form a zygote, and another sperm fuses with two polar nuclei to form endosperm.
What are the two main types of reproduction in plants?
Asexual and sexual reproduction.
Fill in the blank: The female reproductive part of a flower is called the __________.
pistil
Multiple Choice: Which process leads to the formation of seeds? A) Germination B) Fertilization C) Pollination D) Photosynthesis
B) Fertilization
What environmental factors can influence the success of sexual reproduction in plants?
Factors such as temperature, humidity, and availability of pollinators.
True or False: All flowering plants require insects for pollination.
False
What is the role of nectar in plant reproduction?
To attract pollinators to facilitate pollination.
Fill in the blank: The process by which seeds develop into new plants is called __________.
germination
What are the advantages of sexual reproduction in plants?
It promotes genetic diversity and increases resilience to environmental changes.
