Animal- multicellularPlant- multicellularFungi- multicellularProtist- unicellular

Moneran- unicellular

What is a dichotomous key?

A key that scientists use to determine the classification of an organism

Name five things that scientists use for classification

Behavior and physical appearanceMethod of reproduction, locomotion, diet and

habitatCell and DNA analysis

What are the characteristics of insects?

WingsExoskeleton

6 Legs3 Body Parts

TymbalsSpiracles

StridulationSnap Mandibles

Tap Body Parts On Surface

Name the three different mouthparts that insects can have

SpongingPiercing/ Sucking

Siphoning

Name the three different types of metamorphosis

Molting- shedding skinIncomplete- egg, nymph, adult

Complete- egg, larva, pupa, adult

Who was Robert Hooke?

He observed cork cells; coined the term “cell”

Who was Anton Van Leeuwenhoek?

He observed bacteria and protists.

Who was Zacharias Janssen?

He looked at the first compound microscope.

How do you get total magnification?

Eyepiece x Objective lens

How do you properly hold a microscope?

Put one hand on the body tube (arm) and one hand on the base.

What is the stage?

This is where the specimen rests

What is the eyepiece?

The lens that you look through

What are the objective lenses?

They are attached to the revolving nose piece combined with the power of the ocular lens to create the magnified image

Name the levels of organization from cell- organism

CellTissueOrgans

Organ SystemOrganisms

What are the two types of cells (body/ sex cells)?

Somatic and gametes

What is the difference between eukaryotic and prokaryotic cells?

Eukaryotic cells have a nucleus but prokaryotic cells do not

List differences between plant and animal cells

Cell wall- plantChloroplasts- plant

Vacuole size- plants have one big one, animal have smaller ones

What is cytoplasm?

A jelly-like substance that contains organelles

What is the function of the nucleus?

It is the control center for all activities

What is the nucleolus?

It contains genetic material, it also makes ribosomes, and is a dark colored organelle in the nucleus

What is the nuclear membrane?

A membrane that controls movement of materials in and out of nucleus

What are chromosomes?

It is DNA inside the nucleus

What is endoplasmic reticulum?

An internal delivery system that aids in making proteins connects cell membrane to nuclear membrane

What are ribosomes?

Tiny spherical bodies that help make proteins. They are found in the cytoplasm or attached to the endoplasmic reticulum.

What are mitochondria?

The site of cellular respiration. It breaks down sugar molecules to release energy.

What are vacuoles?

Act as a storage area for food, minerals, and waste. In plants they are very large but in animals they are smaller.

What is the cell membrane?

It separates the cell from other cells. Allows molecules to pass through.

What is the function of the cell wall?

Supports and protects the cell

What is chloroplasts?

An organelle in a plant that uses energy from the sun to make food for the plant (photosynthesis)

What are lysosomes?

Organelles that break down larger food molecules into smaller molecules.

What are centrioles?

Organelles that play a role in cell division.

What are golgi bodies?

Organelles that package and distribute materials throughout the cell.

What is Diffusion?

It is the movement of molecules from high concentration to low concentration

What is Osmosis?

Diffusion of water molecules

What is active transport?

The movement of materials through a cell membrane using cellular energy

What is photosynthesis?

The process by which a cell captures energy in sunlight and uses it to make food

What is respiration?

The process by which cells obtain energy from glucose

What is the order of the scientific method and what takes place in each step?

1. Research/ Background information2. State your purpose/ problem question3. State your hypothesis/ make a logical prediction

based on prior knowledge4. Develop your procedure5. Collect and record data (numerical and

observable)6. Analyze your results7. Draw conclusion

What is the independent and dependent variable?

Independent variable- the factor you controlDependent variable- what you are testing/

measuring/ observing

What are the experimental and control group?

Experimental group- the testing groupControl group- the group used for comparison

What are controls?

Controls- what is kept constant throughout the experiment

GOOD LUCK!
