1. What is Interphase? - mainly growth of a cell
occurs in this phase
rather than cell divi-
sion
- most cells live here
- except cancer
2. What is Mitosis? active cell division
3. What is the G1 phase (growth phase)? - Occurs within inter-
phase
- most of cell's life
- more organelles &
proteins
4. What is the S phase (synthesis)? -DNA replication
of 23 pairs (half from
mom & half from dad)
- results in 46 pairs
5. What is the G2 Phase (Growth Phase 2)? -more directly prepar-
ing for M
-make microtubules
6. What is the G0 phase? -no more cell division
- cells just grow
- ex. neuron

7. What is a Niche? An organism's particu-
lar role in an ecosys-
tem, or how it makes its
living.
8. What is an Ecosystem? A biological communi-
ty of interacting organ-
isms and their physical
environment.
9. What is Abiotic? Non-living things
10. What is Biotic? living things
11. What is a Biome? A group of ecosys-
tems with similar cli-
mates and organisms
12. What is a Community? All the different popula-
tions that live together
in an area
13. What is a Species? A group of similar or-
ganisms that can breed
and produce fertile off-
spring.
14. What is Binary fission? A form of asexual
reproduction in sin-
gle-celled organisms
by which one cell di-
vides into two cells of
the same size (usually
in prokaryotes)
15. What is External fertilization? Fertilization that occurs
outside the body of an
organism. The sperms
and eggs are released
in an external environ-

ment. Usually requires
a body of water
16. Who is Antoni van Leeuwenhoek? He discovered both
protists and bacteria.
Advancing the field
of microscopy through
the discovery of mi-
croorganisms.
17. What is Commensalism? A relationship between
two organisms in which
one organism benefits
and the other is unaf-
fected
18. What is Mimicry? The resemblance of
one species to another
species
19. What is Mutualism? A relationship between
two species in which
both species bene-
fit (symbiotic relation-
ship)
20. What is Parasitism? A relationship between
two organisms of differ-
ent species where one
benefits and the other
is harmed
21. What are three essential elements for plant - Magnesium
growth that are obtained primarily through the - Nitrogen
roots? - Potassium
22. What is Intraspecific competition? Competition between
members of the same
species. Ex: Two male
