2.6
tissue
A system composed of tissues that work together to perform a specific function.
Chloroplast
Part of some plant cells that allow the cell to make the
food they need to live using energy from the Sun.
Cell membrane
The layer that controls what enters and leaves the cells,
scale
The size and/or time span
used to make observations (like magnifications of microscopes, or a high speed
or time lapse camera).
standard of comparsion
A type of control, usually used when investigating sick people or
broken machines. By comparing patterns in the sick people to healthy people, a
standard of comparison helps ensure the patterns identified are related to the
cause of the sickness (or broken machines). For example, all the sick people
might have brown eyes, but if lots of healthy people also have brown eyes, this
pattern is likely unrelated to the sickness.
organ
A system composed of tissues that work together to perform a specific function.
Examples: heart, lungs, eyes.
cell wall
A rigid layer outside the cell membrane of plant cells,
bacteria and fungi.
Function
A specific job or role that something or someone completes,
cell
The microscopic building blocks of living things
intellctual honesty
Being honest about data
collected, honest about results, doing your own work responsibly, fairly, and
to your best ability.
organ system
A system composed of organs that work together to perform
a function. Examples: digestive system, nervous system.
Nucleus
Part of the cell that stores and protects the parts of the cell
(genes) that control the cell's growth, reproduction and function.
Unicellular
Organsim made up of one cell
nonliving
Something that does not contain cells and/or does not respond to
the environment.
investigation
Using logic and reason to draw a conclusion from
collected data.
subsystem
A system that is part of a
larger system. Example: an organ like the brain is a system, but it is also a
part of the larger nervous system.
Mitochodira
: Part of the cell that converts food into a form of energy
that the cell can use to grow, reproduce or do its function.
Multicellular
Organism made up of multiple, different types of cells.
living
Something made of cells
that gathers food and water from the environment, disposes of waste, and reacts
to changes in the environment so they can survive and grow.
Ambiguity
When answers cannot be known
with 100% certainty.
system
A group of interacting
parts that work together to perform a function.
Cytoplasm
The interior of any cell. There are many structures and
functions that happen here that are too small to see even with a microscope.
microsopic
Things that are too small to be seen without a microscope
outlier
A data point that does not follow the same
pattern as the rest of the data.
Germ
Something that makes
people sick AND can be passed from person to person making others sick.
