Characteristics of Living Things: Vocabulary
A living thing-- this is an individual example
of a specific species of living thing.
ORGANISM
Comparing Similarities Between Living Things
Characteristics of Living Things: Vocabulary
There are seven characteristics that all living things share with one another:
 All living things RESPIRATE
 All living things EXCRETE waste
 All living things require NUTRIENTS
 All living things GROW
 All living things REPRODUCE
 All living things are SENSITIVE to their environment
 All living things MOVE
***Of course within any species, there are injuries or problems with the body
that can cause one of these features to not work properly– this does not mean
that the organism isn’t “alive”. For instance, a dog who has had its
reproductive organs removed (spayed or neutered) is not suddenly a “nonliving thing”
Introduction to Cells: Vocabulary
This is the smallest individual part of an organism that can
still be considered "alive". It is capable of carrying out all
life functions that living things do (such as respirate,
excrete, reproduce, etc.)
CELL
Introduction to Cells: Vocabulary
This is a type of organism made of many cells working
together. An example would be a human being
MULTICELLULAR ORGANISM
Introduction to Cells: Vocabulary
This is a type of organism that is made of only a single
cell. An example of this would be bacteria.
UNICELLULAR ORGANISM
Introduction to Cells: Vocabulary
These are microscopic, single-celled organisms that live
everywhere. Some types of these cause food to spoil;
other types of these can make you become sick.
BACTERIA
The Organelles of a Cell: Vocabulary
This is the gelatin-like liquid that makes up the majority of the cell.
CYTOPLASM
This is the outer layer of a cell that separates and protects the cell
from the environment around it.
CELL MEMBRANE
This is the organelle in a eukaryotic cell which in which you would
find the genetic material (DNA) for the cell.
NUCLEUS
Cellular Processes: Vocabulary
This cell process is when water seeps into and out of a cell through the cell
membrane in order to maintain appropriate water levels within the cell.
Osmosis
During osmosis, water moves from areas of _____ concentration
of water, to areas of _____ concentration of water
HIGH CONCENTRATION TO LOW CONCENTRATION
Cellular Processes: Vocabulary
This is a cellular process during which a cell oxygen is used to burn
glucose, creating energy for the cell; this process takes place in the
mitochondria.
CELLULAR RESPIRATION
What materials are NEEDED for cellular respiration?
GLUCOSE (SUGAR) AND OXYGEN
What materials are PRODUCED by cellular respiration?
ENERGY, CARBON DIOXIDE, AND WATER
Cellular Processes: Vocabulary
This is a process in which plant cells uses the convert the energy from
sunlight into glucose molecules in order to provide the plant cell
with an energy source. Inside the cell, this process takes place in the
chloroplast.
PHOTOSYNTHESIS
What materials are NEEDED for photosynthesis?
CARBON DIOXIDE, WATER, SUNLIGHT
What materials are PRODUCED by photosynthesis?
GLUCOSE, OXYGEN
Today’s Topic:
How do the different
organelles of a plant cell
support the life processes
of a cell?
Plant Cells: Basic Facts
• Go to “What did we do today in Science?” on my wiki
to view microscopic images of plant cells
•Notice that plant cells have a somewhat rectangular
shape
•Also notice that plant cells have many green circles
floating around inside– these are the chloroplasts,
responsible for photosynthesis
