the condition of not being alive
organism
a living thing
cell
the basic unit of structure and function in an organism
unicellular
single-celled organism
multicellular
organisms with more than one cell
growth
the process of becoming larger
development
the process of becoming more complex and mature
stimulus
a change in an individuals environment
response
an action or change in an individuals behavior
reproduction
the ability to produce offspring that are similar to the parents
cell theory
a widely accepted explanation of the relationship between cells and living things
4 characteristics of living things
grow and develop
organized - cells
reproduce
respond to their environment
3 needs of living things
materials
energy
living space
3 parts of the cell theory
all living things are made of 1 or more cells
cells carry out the functions needed to support life
cells come only from other living cells
microscope
tool used to make small objects look larger than they really are
Louis Pasteur
Developed "Pasteurization"- using heat to kill bacteria
Spontaneous Generation
Some scientists believe that bacteria grew from non-living materials.
Robert Hooke
Gave the "cell" it's name. Looked at the bark from a cork tree. He said that it looked like tiny compartments.
Anton Van Leeuwenhoek
Inventor of the first microscope.
cell
the smallest unit that is able to perform the basic functions of life
cytoplasm
a thick, gelatin-like material contained within the cell membrane. Most of the work of the cell is carried out in this
nucleus
the structure in a eukoryotic cell that contains the genetic material a cell needs to reproduce and function
eukaryotic cell
a cell in which the genetic material is enclosed within a nucleus, surrounded by its own membrane
prokaryotic cell
a cell that lacks a nucleus and other organelles, with DNA that is not organized into chromosomes (BACTERIA)
organelle
is a structure in a cell that is enclosed by a membrane and that performs a particular function
cell wall
a protective outer covering that lies just outside cell membrane of plant cells
chloroplast
an organelle in a plant cell that contains chlorophyll, a chemical that uses the energy from sunlight to make sugar
mitochondria
organelles that release energy by using oxygen to break down sugars
Cell membrane
The outer boundary of the cytoplasm
Lysosome
break down materials and old cell parts inside the cell with chemicals
vacuole
enclosed by a membrane and holds water and waste materials
specialization
specific cells perform specific functions
tissue
a group of cells with a similar function that are organized to do a job
organ
different tissues that work together
organ system
organs and tissue working together
organism
the highest level of organization
examples of prokaryotic cells
bacteria
examples of eukaryotic cells
amoeba, paramecium, euglena and volvox-plants and animals
bacteria
single celled organism without a membrane bound nucleus or organelles-prokaryotic
paramecium
animal like, oral pore like a mouth. Gets it's food from other sources (heterotroph). Guides food into oral groove(mouth) by cilia.
euglena
plant and animal like, heterotroph and autotroph, has a whipilike tail called a flagellum to allow motion
volvox
plant like, rolls around and is an autotroph (makes food) so it uses photosynthesis
amoeba
animal like, has pseudopodia (false feet) to engulf food items
Amoeba
moves by way of pseudopod
Paramecium
moves by way of cilia
Oral Groove
the mouth of the paramecium where food is taken in by the movement of cilia
Euglena
moves with a single flagella
Eye Spot
An organelle of euglena that is sensitive to light.
Volvox
Lives and travels in colonies (or groups). It moves by using flagella
Cell
Basic unit of life
Protist
A kingdom of mostly single-celled organisms with a nucleus
Animal like protists
paramecium and amoeba
Protozoa
Another name for animal-like protists
Pseudopod
A "false-foot" that some protists have to move.
Cilia
Small, hair-like structures that surround the body of a protist to help them move.
Flagella
A long whip-like tail that some protists use to move.
Unicellular
made up of 1 cell
Plant like protist
Volvox
Amoeba and paramecium
Heterotroph- must eat to gain energy
euglena
Heterotroph AND autotroph- can make food by photosynthesis AND eat
plant and animal like protist
euglena
autotrophic
makes own food through photosynthesis (ex: volvox)
