Honors Bio Quiz

Made up of one or more cells

Cell - the basic unit of life (smallest unit). All organisms are made of one or more cells. Unicellular - one cell, multicellular - multiple cells.

Biological Hierarchy: organization of living systems. Cells → tissues → organs → organ systems → organism

Displays Organization

Each structure in an organism has a specific function. EX: your bladder (structure) is a storage container (function) for urine.

Grows and Develops

Growth: the addition of mass and the formation of new cells.

Development: the process of physical changes that take place during the life of an organism.

Reproduces

The production of offspring. Organisms reproduce and pass along traits from one generation to the next.

Responds to Stimuli

Reactions to internal and external stimuli are called responses.

Ex: this cheetah responds to the need for food by chasing a gazelle. The gazelle responds by running away.

Requires Energy (metabolism)

Energy is required for all life processes. Many organisms, like this mouse, must take in food. Other organisms make their own food.

Maintains Homeostasis

All organisms keep internal conditions stable by a process called homeostasis.

Ex: humans perspire to prevent their body temperature from rising too high.

Adaptations Evolve Over Time

Adaptations are inherited changes that occur over time that help the species survive.

Ex: tropical orchids have roots that are adapted to life in a soil-less environment.

Diaphragm

Platform under lenses

Stage

Big knob

Coarse adjustment knob

Small knob

Thing holding up the thing connected to the eyepiece

Arm

Circle thing that holds the lenses

Nosepiece

Lens thing connected to the nosepiece

Objective lens

Underneath the stage

Stage clips

Ocular lens

10x (always, you multiply with objective lens)

Objective lens

Ex: if the total power says 300X, then the objective lens is 30X.

Eyepiece

Contains the Ocular lens

Nosepiece

Holds the different objective lenses and can be rotated to change magnification

Objective lens

Increases the total magnification of the specimen

Stage clips

Secure the slide with the specimen

Diaphragm

Used to adjust the amount of light on the specimen

Light source

Projects lights upwards through the slide and specimen

Ocular lens

Magnifies by 10x

Arm

Used to support the microscope when carried

Stage

Supports the slide being viewed

Coarse adjustment knob

Move the stage up and down for focusing

Fine adjustment knob

Moves stage slightly to sharpen the image

Base

Supports the microscope
