The loss of a single species
may cause a ripple effect felt
across an entire ecosystem.
This “kind” of species is called
a _____________species because
it has an unusually large effect
on its ecosystem.
Continue
300
This is any type of change that can
make an organism better suited for
its environment.
Continue

Organisms that make their own
food are autotrophs, but these are
organisms that eat autotrophs
(directly or indirectly)

In population ecology, this
describes the maximum number
of individuals that a stable
environment can support
indefinitely.

Some tiny prokaryotes (bacteria)
have been found that make their
own food without sunlight.
_______________is the process by
which an organism makes food
using chemicals (rather than light)
as an energy source.

In a particular food chain, grass is
eaten by rabbits that are eaten by
owls. In this food chain, the grass
is the producer and the rabbit is
the _____________consumer
Continue

1. _________: organisms that eat only
plants.
2. ___________: organisms that eat
only animals.
3. _____________: organisms that
break down organic matter into
simpler compounds
Continue

The principle of ______________
_______________ states that when two
species are competing for the
same resources, one species will
be better suited to the niche, and
the other species will be pushed
into another niche or become
extinct.

These are 2 examples of A)abiotic
factors in an ecosystem and 2
examples of B)biotic factors in an
ecosystem.

We always begin
examining microscope
slides with this objective
lens in place
Continue

This category of cells has a
definite nucleus and organelles.
Continue
300
A bacteria cell is _____________,
since it has no nucleus or
membrane-bound organelles
Continue

“This” microscope part regulates
the amount of light on a standard
microscope.

The ocular lens of a microscope
has a magnification of 10X and the
objective lens has a magnification
of 40X. The total magnification
is….

In the microscope lab, this is the
most notable difference between
the onion epidermis cells and the
Elodea leaf cells
Continue
700
This is the highest magnification a
scope could have (with an eyepiece
at 10X, a low power objective at
10X and a high power objective at
50X)

The Cell Theory states that 1)All
organisms are made of __________,
2)All existing cells are produced by
other living ___________, and 3)The
____________is the most basic unit of
life.

This “type” of microscope with a
light source shining from a)above,
b)beneath or c)both gave us the
chance to see our pond water
sample in “3-D”.

Within a membrane, a cell is filled
with a “jellylike substance” called
a)______________ that contains
dissolved molecular building
blocks. In some cells, this “jellylike” substance also contains
b)____________, structures
specialized to perform distinct jobs
in the cell.

This is a long whip-like tail used for
cellular locomotion.
Continue
200
This is a major difference between
rough and smooth E.R.
(endoplasmic reticulum)
Continue
300
This is the organelle used in
photosynthesis ; it helps to convert
the sun’s energy into food.
Continue
400
This is the cell organelle that helps
to make the proteins that carry out
endless jobs in our bodies
Continue
500
The process of moving molecules
out of a cell
Continue
600
These are the cells recycling
centers: they contain digestive
enzymes to digest damaged or
foreign material
Continue

List three things that all cells have
in common
Continue

This organelle packages,
processes and ships proteins and
fats; it also functions in producing
lysosomes
Continue

Mitochondria and chloroplasts
contain a small amount of this
genetic material…it allows them
to direct the production of some
of their own proteins

V Words!
A ____________is a fluid filled sac
used for storage of material by the
cell whereas a _____________ is a
general name describing small
membrane-bound sacs that
transport materials from place to
place.

A membrane is said to be “this” if
it allows only certain molecules to
pass.
Continue
200
This is the current cell membrane
“model” describing a cell’s texture
and appearance
Continue
300
Movement of molecules across a
cell membrane that does not
require energy input from the cell.
What is passive transport
Continue
400
This is the process by which
water travels from areas of
higher to lower concentration
across a membrane
Continue
500
___________transport drives
molecules across a membrane
from a region of low concentration
to high concentration with the
input of energy.
Continue
600
A type of endocytosis in which the
cell membrane “engulfs” large
particles to bring them into a cell.
Continue
700
If one of the high energy, unstable
phosphate bonds “breaks” from
adenosine triphosphate (ATP),
energy is released, and “this”
molecule is produced.
Continue

When a cell (90% water and 10%
salt) is placed into an environment
that is 92% water and 8% salt, the
cell will likely do “this”.

substances on either side of a
membrane are the same, the
system is said to be in

Elephants are larger than mice,
right? This is the reason why an
elephant’s cells are not much
larger than a mouse’s cells.
