Patterns of Reproduction
A reproductive process that involves only one parent and produces offspring that are genetically identical to the parent.
What is asexual reproduction?
Plants have complex life cycles that include these two different stages.
What are sporophyte and gametophyte?
This is a response to a stimulus that is inborn and an animal performs correctly the first time.
What is an instinct?
This is a change or signal in the environment that can make an organism react in some way.
What is a stimulus?
Blending of colors occurs from mixing a dominant and recessive allele is an example of this.
What is incomplete dominance?
The process is sexual reproduction in which an egg cell and a sperm cell join to form a new cell.
What is fertilization?
The process of transferring pollen from male reproductive structures to female reproductive structures.
What is pollination?
A chemical released by one animal that affects the behavior of another animal of the same species.
What is a pheromone?
This is a plant's growth response toward or away from a stimulus.
What is tropism?
True or false: Mitosis produces daughter cells that are genetically different from parent cells.
What is false?
A reproductive process that involves two parents that combine their genetic material to produce a new organism which differs from both parents.
What is sexual reproduction?
Grafting is an example of this type of reproduction.
What is asexual reproduction?
This occurs when eggs are fertilized outside of a female's body.
What is external fertilization?
A plant's response to seasonal changes in length of night and day.
What is photoperiodism?
True or false: Meiosis produces daughter cells that are genetically different from parent cells.
What is true?
A specific characteristic that an organism can pass to its offspring through its genes.
What is a trait?
This type of plant increases its chance of fertilization with pollen from male cones that can be carried by the wind and sticky substances on the female cone.
What is a gymnosperm?
This is a regular, seasonal journey of an animal from one place to another and back again.
What is migration?
This is when an embryo develops inside the mother's body.
What is placental development?
Trees such as pines, redwoods, firs, cedars and hemlocks are classified as this because they have cones and unprotected seeds.
What are gymnosperms?
A sequence of DNA that determines a trait and is passed from parent to offspring.
What is a gene?
The sprouting of an embryo out of a seed; occurs when the embryo resumes its growth following dormancy.
What is germination?
This is often the goal of animal communication.
What is reproduction?
The process in which an animal's body undergoes major changes in shape and form during its life cycle.
What is metamorphosis?
This type of plant produces flowers and fruits that contain seeds. (Fruit is the ripened ovary and other structures that enclose one or more seeds)
What is an angiosperm?
