thirst
is an example of internal stimulus
internal stimulus (example)
thirst
cell
is the basic unit of structure and function in an organism.
external stimulus (example)
change in temperature in the envionment
spontaneous generation
= the mistaken idea that living organisms arise from nonliving sources
heterotrophs
= organisms that get energy by consuming pther organisms
response
with that an organism reacts to a response
external
from the outside
internal
from the inside
homeostasis
= an organisms ability to maintain stable internal conditions
reproduce
= to produce offsprings that are similiar to the parents
six characteristics all living things share?
cells (with nucleus cell membrane), organs, tissues and organs systems
How did Redi's Experiment help disporve the idea of spontanous generation?
in ome jar no living things grew, in the other jar they did
What are the 4 basic needs all living things must satisfy?
-energy
-water
-living space
-stable internal condition (homeostasis)
Describe the difference between growth and development:
growth: increasing in size
development: increasing in skills
Robert Hook
one of the first people to observe cek=lls
Leuwenhoek
was the first person to see single cell organisms
Matthias Schleiden
concluded that plants are made up of cells
Schwann
concluded that animals are made up of cells
Virchow
proposed that all cells come from other cells
resolution
magnification: is to see the ability to distinguish the individual parts of an object
electron microscop/light microscop
electron microscop:

light microscop
microscop
any instument that makes small object look larger
compound microscope
a light microscope that has more than one lens
cell theory
a widely accepted explanation of th erelationship between cells and living things
magnification
the ability to make things looking larger than they are
convex lens
a curved lens that is thicker in the middle than t the edges
nucleus
Is the brain of the cell.
endoplasmatic reticulum
Carries materials from one part of the cell to another.
mitochondria
Produses most of the energy the cell needs to carry out its functions.
cell membrane
cells with out a cell wall have a cell membrane, which separates the cell from its surroundings.
organells
They are tiny cell structures that carry out specific functions within the cell.
cellwall
A nonliving surface around the plant cell.
chromatin
Strands of genetic material floating around inside the nucleus
ribosomes
Produce protein
Golgi bodies
receives protein and other newly formed materials and distributes them all over the cell
Chloroplasts
captures sunlight and uses it to produce food for the cell. It also gives the plant the green color.
vacuole
It is the cells storage area.
lysosomes
They are small roung structures that break big food partcals into very small ones.
selective breeding
using technology to change and organism in any way you what it to be or look like.
Heredity
the process in which the traits pass from a parent to an offpring
