Patterns of Reproduction
What is asexual reproduction?
A reproductive process that involves only one parent and produces genetically identical offspring.
What do flowers produce?
Flowers produce seeds and sometimes fruits.
What is a mating call?
A sound made by an animal to attract a mate.
Name one internal factor affecting growth.
Genetics
How does sexual reproduction differ from asexual reproduction?
Sexual reproduction involves two parents and leads to genetic variation in offspring, while asexual reproduction involves one parent and produces identical offspring.
What structure attracts pollinators?
Petals attract pollinators with their colors and scents.
What is the benefit of living in groups?
Living in groups can provide protection from predators and increase the chances of finding food.
What is one external factor affecting growth?
Environmental conditions such as temperature or availability of food.
What is fertilization?
The process when a sperm cell and an egg cell combine to form a new organism.
What do gymnosperms have instead of flowers?
Gymnosperms have cones as their reproductive structures.
Why do animals migrate?
Animals migrate to find better food sources or favorable climates for breeding.
How does competition affect growth?
Competition for resources can limit the growth of individuals in a population.
What is external fertilization?
When eggs are fertilized outside of the female's body, common in many fish and amphibians.
What is an amniotic egg?
An egg that has protective membranes and is found in reptiles and birds, allowing for development outside the mother's body.
What is cooperative behavior?
When animals work together for mutual benefit, such as protecting young or hunting.
How do environmental conditions affect growth?
Poor environmental conditions, like lack of nutrients or space, can hinder growth and development.
Explain incomplete dominance.
A genetic situation where one allele for a trait is not completely dominant over another, resulting in a third phenotype that is a blending of both traits.
What is the role of the placenta?
The placenta provides nutrients and oxygen to the developing embryo inside the mother.
What is a territory?
An area defended by an animal or group of animals to secure resources like food and mates.
What role do hormones play in growth?
Hormones regulate various growth processes and development in organisms.
