Asexual and Sexual reproduction Flashcards
What does Asexual reproduction do?
It creates identical offspring from one organism, while sexual reproduction involves gametes from two parents.
What does asexual reproduction result in?
No genetic diversity
What does asexual reproduction involve?
One organism and results in clones
What is a simple form of asexual reproduction?
Bacteria reproduced by binary fussion
What does sexual reproduction that combines gametes lead to?
Genetic Diversity
What can sexual reproduction from genetic diversity result in?
An enhance (increase) in chance of survival in changing environments.
What does the asexual reproduction process do?
Allows organisms like spider plants and bacteria to quickly reproduce, ensuring efficiency but no genetic variation.
What does the Binary Fussion process do?
Split bacteria (simple organisms) into two, showcasing a basic and fast method of reproduction WITHOUT genetic diversity.
Where does sexual reproduction in plants occur?
Flowers!!
What does the process of sexual reproduction in plants involve?
-Pollination
-Fertilization
-The formation of seeds
What does sexual reproduction in plants lead to?
Plant Diversity!
What do flowers contain for reproduction?
Sexual Organs
Types of pollination. list 3
-Wind
-Water
-Pollinators
What are pollinators crucial for?
Food supply
What does fertilization lead to?
Seed development within the ovary
What does the ovary transform into? Doing what to the seed?
-Transforms into fruit
-Enclosing the seed
What happens to the seeds?
They’re dispersed in various ways, including human activity.
What is the flower structure designed with?
The stamen and carpal that facilitate sexual reproduction.
Different pollination methods such as wind, water, and animals affect what in flowers?
Their characteristics which indicates adaption to their environment.
Why are pollinators important?
They assist in plant reproduction BUT importantly play a vital role in maintaining our food system.
What does the process of fertilzation involve?
It involves pollen tubes and male gametes
What are pollen tubes and male gametes crucial for?
It is critical for seed development, ensuring the continuation of plant species.
What happens after fertilization in fruit development?
The ovary enlarges into fruit
Why is it important for the ovary to enlarge into fruit?
It protects and aids in the dispersal of seeds, illustrating the plant’s reproductive strategy.
What does the various methods of seed dispersal ensure?
Genetic diversity and the colonization of new areas, showcasing plants’ adaptability.
What does the reproductive cycle contribute?
This process contributes to the vast diversity of plant life on Earth

Female gametes
When a pollen grain and an ovule meet they form a?
Zygote
