Vocab 1
all the organisms of the same kind living in the same place
the living and nonliving things in an area interacting with each other
ecosystem
where the "blueprint" of the cell is located
chromosomes
Why do scientists consider cell growth one of the most important areas of study in all biology
Cells are basic unit of life. Understanding cells helps you understand life threatening diseases such as cancer
the role a kind of living thing, or species, plays in a food web
niche
a sac-like space in a cell’s cytoplasm for storing materials such as food or waste. Plants ones are larger than those in animals
vacuole
all populations living together in the same place
community
How do land barriers affect the climate of an area
Moist air is pushed up one side of mountain. Air loses moisture as it descends on other side
an nonliving part of an ecosystem, such as water, minerals, sunlight, air and soil
abiotic factors
the division of the nucleus while a cell is dividing into two identical cells
mitosis
What cell part is bacteria missing that most cells have
clearly defined nucleus
How could you model osmosis in a cell using beans and yarn
Beans bunched up outside the yarn and a few inside, put more inside until equilibrium is reached
What does diffusion mean
When molecules move from an area of high concentration to an area of low concentration
respiration in a cell that is carried on without oxygen
fermentation
the division of the nucleus resulting in cells with half as many chromosomes as in other cells
meiosis
What are some examples of biotic factors (5 total)
Animals, plants, fungi, protists, bacteria
What are the phases of mitosis in order and which phases does the chromosome pair split
Interphase, prophase, metaphase, anaphase, and telophase. Chromosomes split during anaphase
Why does the rain forest biome have a greater diversity of plant and animal life than the desert biome
The warm, moist environment supports more life instead of the dry, extreme temperature of the desert
a gel-like substance that surrounds a cell’s nucleus and is the place where most cell activities occur
cytoplasm
the process of “unlocking” energy in sugar that takes place in the mitochondria of a cell
respiration
What activities do all living things participate in (6 total)
Taking in food, respiration, excretion, response/movement, growth, and reproduction
What are the components that make up the American grasslands including abiotic and biotic factors
Mid latitudes, cool winters, hot summers, some precipitation, small shrubs and grass, prairie dogs, gophers, birds, insects, bison, elk
