Microscopic Ecosystems
a single-celled organism that lives in the ocean, fresh water or soil
amoeba
the jelly like substance within a cell, located outside the cell nucleus
cytoplasm
when one organism benefits while the other is negatively affected
parasitic relationship
organisms that make their own food through the process of photosynthesis
producers
divided into groups according to how they move
protozoans
the organelle that is the control center of the cell
the nucleus
Robert Hooke used a microscope to observe objects, but this person was the first to observe cells that were alive
Anton Van Leeuwenhoek
The variety of organisms in a given ecosystem
Biodiversity
According to the _________ __________, all living things are composed of cells, cells are the basic unit of structure and function in living things, all cells are composed from other living things.
Cell Theory
these live in your intestine and help break down food which are an example of mutualism
Escherica coli
The process by which green plants produce their own food.
Photosynthesis
allowed Hooke to see "tiny rectangular rooms" which he called cells
a microscope
Supports and protects the cell and is found in all cells
cell membrane
according to the ________ ___________ all organisms are made of cells
cell theory
An organelle found only in plants. Its function is to support and protect the cell
cell wall
the basic unit of structure and function in living things
cells
work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each
chloroplasts
a light microscope that has two or more lenses
compound microscope
organisms that recieve energy by eating other organims
consumers
This made it possible for people to discover cells
invention of the microscope
______ parts of an ecosystem are biotic factors
living
perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy. This energy is then in turn used by the cell to carry out various functions
mitochondria
_______ parts of an ecosystem are abiotic factors
noliving
this is found in the cell's nucleus, the center of the cell
organisms genetic information (DNA)
counting the number of organisms in a smell area and multiplying to estimate the number in a large area
sampling
a close relationship between two species that benefits at least one of the species
symbiosis
they can be used to contain cellular waste and to isolate materials that may be harmful to the cell
vacuole
