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.

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

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.

We always begin examining microscope slides with this
objective lens in place
200
This category of cells has a definite nucleus and organelles.

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)
Continue

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.
Continue

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 “jelly-like” substance
also contains b)____________, structures specialized to perform
distinct jobs in the cell.

This is a long whip-like tail used for cellular locomotion.

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
700
List three things that all cells have in common
Continue
800
This organelle packages, processes and ships proteins and fats; it also functions in producing lysosomes
Continue
900
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.
Continue
100
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
Continue
This is the process by which water travels from areas of higher to lower concentration across a membrane
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
800
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”.
Continue

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