Patterns of Reproduction
This method of reproduction provides more genetic variation and is therefore more beneficial to keeping organisms adaptable to the environment.
What is sexual reproduction
The male reproductive part of the flower is called ____ and has two parts.
What is the stamen and contains the anther and filament.
What is the difference between a learned behavior and an innate behavior?
A learned behavior is a behavior that an organism has to learn through experiences. An innate behavior is a behavior that an organism is born with.
This tropism refers to a plant growing towards the direction of light
What is phototropism
A homozygous dominant and a heterozygous organism produce an offspring. What is the probability that the offspring has straight hair?
Curly hair is dominant to straight hair.
0%
Because this reproduction involves one parents, this reproduction results in less genetic variation.
What is Asexual Reproduction.
Some animals do not look like a younger version of themselves because they go through a major body change.
What is metamorphosis.
The difference between a trait and a gene
What is the difference between germination, pollination and fertilization and what order must they occur?
Pollination happens first, that is when pollen is able to be moved from the male reproductive structure to the female reproductive structure.
Fertilization is when the egg and sperm cells combine to produce a zygote.
Germination is when an embryo sprouts out of the seed.
Pollination must occur first for fertilization to occur and then germination will occur after
This regular, seasonal journey that some animals take part in doing in order to have access to more resources, better climate or to reproduce more.
What is migration
Why is dormancy essential for plant survival?
Dormancy is essential because it ensures plant survival by preparing the plant for winter and the harsher weather by stopping growth and activity.
We mentioned two types of asexual reproduction. One is fragmentation and one is budding. Define and provide an example of each.
Fragmentation is when a new organism forms from a piece of the original. Example is a star fish.
Budding is when a new organism grows from the parent until it is fully mature. Example is sponges
In vascular plants, the gametophytes develop inside of these structures. (Answer needs to be for gymnosperms and angiosperms)
What is inside cones for gymnosperms and inside flowers for angiosperms.
How does parental investment correlate to the survivability of offspring. Provide an example.
The more parental investment results in a higher survivability rate. Animals that produce a lot offspring (turtles) will more than likely not provide parental care whereas animals that produce few offspring (gorillas) will see their offspring live.
Using a squirrel as the animal, provide an example of an acquired trait and an inherited trait.
What is Teeth, Claws or fur color for inherited. Acquired traits can be climbing, locating/opening acorns.
For gymnosperms and angiosperms, ____ is required for pollination to happen AND fertilization.
Monogamy, Polyandry, Polygyny and Polygynandry are different mating systems. Define each of them.
Monogamy is one female mate with one male mate.
Polyandry is one female mates with multiple mates
Polygyny is one male mates with multiple mates.
Polygynandry is female mates with multiple males and males mate with multiple females
