smallest units of living things that are themselves alive- can be unicellular or multicellular

2 types of reproduction

sexul and Asexual

Sexual reproduction

2 different cells unite and the offspring looks like a little of both


a new organism is formed from a singe parent

Unicellular organisms grow and develop how?

grow in size

Multicellular organisms grow and develop how?

grow in size and shape, initial cell replicates and eventually differentiates


what everything needs to maintain life and grow


the break down or build up of materials to carry out life process

The sun

is the ultimate source of energy for everything


signal that brings response, internal and external (shivering when cold, sweating when hot)


The process of keeping internal conditions the same

the 2 types of Evolution

Macro and Micro

Micro Evolution

Grow as a population, each generation differs

The genetic code

DNA (deoxyribonucleic acid)


The part of the earth that contains all ecosystems


A community and its nonliving surroundings


Populations that live together in a defined area


A group of organisms of one type that live in the same area


An individual living thing

Group of Cells

Tissues, organs, and organ systems


Groups of atoms; smallest unit of most chemical compounds

What does a Microscope do?

It produces magnified images of structures that are to small for the human eye to see.

What are the 2 types of microscopes?

Light Microscope (compound), Electron Microscope

What does a Light Microscope use?


What does a Electron Microscope use?


What is the most a Light Microscope can magnify?


Light Microscopes can not produce a clear image of things up to?

0.2 micrometer

What is the most a Electron Microscope can magnify?


What is more detailed than a light microscope?

Electron Microscope

What are the 2 types of Electron Microscopes?

Transmission Electron Microscope, Scanning Electron Microscope

Transmission Electron Microscope

Beams electrons through the specimen and produces a flat image

Scanning Electron Microscope

Beams electrons back and forth across the surface, and creates a 3D image


Contains a magnifying lens


Supports the body tube


Supports the slide being observed

Fine adjustment knob

Moves the body tube slightly to sharpen the image

Coarse adjustment knob

Moves the body tube to sharpen the image


supports the microscope


Produces light or reflects light up two toward the eyepiece

Stage Clips

hold the slide in place

Low-Power Objective

Provides a magnification of 10x and is the shortest objective

High-Power Objective

Provides a magnification of 40x and is the longest objective

Nose piece

Holds the objectives and can be rotated to change the magnification
