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
