Examining Diversity
Interdependence
Variation
Variation 2
Asexual and Sexual Reproduction
100
the number and variety of organisms in an area
What is "biological diversity"
100
when two or more species using the same limited resource
Interspecies competition
100
Variations within a species is referred to as:
VARIABILITY
100
What are Heritable Characteristics? Give two examples.
Characteristics that are passed on from generation to generation; from parents to children. For example eye colour.
100
What are the 4 types of asexual reproduction that were talked about in class.
vegetative reproduction, spores, budding, binary fission
200
a particular environment where living things interact with other living things and non-living things
What is an ECOSYSTEM
200
What is resource partitioning
division of a resource among two or more coexisting species such that the niche of each species differs slightly
200
a process in which the environment "selects" which individuals will survive and reproduce
Natural selection
200
What are NON-HERITABLE characteristics? Give two examples.
Characteristics that are acquired in life and are not passed on to other generations. For example: learning to play the piano
200
Process by which a single parent reproduces by itself
What is Asexual Reproduction.
300
a group of individuals of the same species living in an area
What is a POPULATION
300
the relationship between species in which one species benefits, and the other species neither benefits nor is harmed
COMMENSALISM
300

A green eyed cat and a blue eyed cat would be intra or interspecies variation?

Intraspecies variation

300
refers to differences in characteristics that have a defined form as in either you have it or you don't. Example: blue eyes
What is discrete variation.
300
Explain the differences and similarities between sexual and asexual reproduction. Which is better? Why?
Answers will vary.
400
a group of populations of different species living in the same area
What is a COMMUNITY
400
the relationship between species in which both species benefit
MUTUALISM
400
How does variation HURT survival?
answers may vary
400
refers to differences in characteristics that have a range of forms. Example: height in adults can range from 1.2 m to 2.1 m
What is continuous variation
400
Explain how an embryo is created during sexual reproduction (use specific vocabulary, including: gamete, sperm cell, egg cell, zygote, fertilization, cleavage, and embryo)
a male gamete (sperm cell) fertilizes a female gamete (egg cell) --> the joining of the sperm and egg produces a single-celled zygote --> cell division of the zygote occurs (cleavage) --> a multi-celled embryo develops.
500
Write down the classification system in the right order
kingdoms, phyla, subphyla, classes, orders, families, genera, species
500
the relationship between species in which one species benefits and the other species is harmed
PARASITISM
500
How does variation HELP survival?
answers will vary
500
Explain how the environment affects variation.
Some variations in individual organisms result from interactions with the environment. Imagine, for example, you have two plants that are completely identical. If you put one plant in a sunny window and the other in a dim closet, they would soon begin to look very different. The one in the sunlight would be green and bushy, but the plant in low light would be a pale green and spindly. (or height and diet!)
500
Draw the parts of a flower. Explain what cross-pollination is.
pollen, stamen, ovules, pistil, pollination, anther, stigma... cross pollination occurs when the pollen of one plant is carried to the stigma of another by wind, water or animals.
