Semester 1 Review By Alyssa Vavra, Caroline Ditzler, Neha Vagvala

Classification What is the proper format to write a scientific name?

First letter in the genus capitalized, a comma between the two names, and both words italicized

Name all seven characteristics of living things (MRS. GREN) Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition

What is the forth largest classification level?Order

Name the five kingdoms Animal, Plant, Fungi, Protists, Moneran,

Name Whether Unicellular or Multicellular Animal- Multicellular Plant- MulticellualrFungi- Multicellular Protists- Unicellular Moneran- Unicellular

Classification Lion- Tiger or Crocodile Pig- Primate or Squirrel Dog-Fox or Cat Cougar- Lion or Tiger Bony Fish- Penguin or Snake

List 3 forms of evidence scientists Use when classifying animals. Behavior Physical Appearance Methods of reproduction Locomotion (movement) Deit Habitat Cells and DNA analysis

Insects What is an arthropod?

An invertebrate animal of the large phylum Arthropoda, such as an insect, spider, or crustacean.

Name the most diverse and populous order

Coleoptera

Name 4 characteristics of an insect

Head, thorax, abdomen, two pair of wings, an exoskeleton, three pairs of legs, compound eyes, mandibles, and a pair of antenna

Name the three different types of mouthparts

Siphoning, piercing, sponging

Name the 3 types of metamorphosis

Molting, Incomplete, Complete

What stages are included in incomplete metamorphosis?

Egg, nymph, adult

Egg, larva, pupa, adult

Complete

Microscopes Name the 3 founding fathers

Hooke, Leeuwenhoek, Janssen

What did Janssen do?

Made the first compound microscope

Cells Describe the difference between somatic and gametes cells

Somatic cells are body cells and gametes cells are sex cells

What main feature are Prokaryotic cells missing

They don’t have a nucleus

CellsWhat are 3 differences between plant and animal cells?

Plant cells have a cell wallPlants have chloroplasts in their cells

The vacuole size is larger in plant cellsList all organelles and their functions(15)

Cytoplasm- supports and protects cell organelleCell membrane- protects, controls movement, and maintains homeostasis

Chloroplasts- uses energy from the sun to make foodCentrioles- play a role in cell division

Chromosomes- controls activities of the cell and pass on traitsCell wall- supports, protects, and allows H2O, O2, CO2 to pass through the cell

Nucleus- controls cell activitiesNucleolus- site where ribosomes are made

Nuclear membrane- controls movement of materials in and out of nucleusER- carries materials through cells (internal delivery system)

Ribosomes- produce proteinsMitochondria- breaks down sugar molecules into energy

Vacuole- stores food, water, and wasteLysosomes- breaks down larger food molecules and digests old cell parts

Golgi bodies- like a post office, it modifies and distributes proteins

CellsWhat is diffusion?

Diffusion is the process of which molecules move from an area of higher concentration to a lower concentration.

How is osmosis related to diffusion?

Osmosis is the diffusion of water.

What is active transport?

Active transport is the movement of materials through a cell membrane using cellular energy.

What are the three things for photosynthesis to occur?

Water, sunlight, and carbon dioxide

What is respiration?

The process of which cells obtain energy from glucose.

Scientific MethodList the steps of the scientific method in order?

What takes place in each step?Problem Question- developing question

Research- getting background informationHypothesis- making an educated guess based on researchDevelop your procedure- conduct your experiment and

Collect and record Data- record your results from your experimentAnalyze your results

Draw Conclusion

Independent variable- The factor you control Dependent variable- what you are testing/measuring/observing Experimental group- what testing group Control group- the group used for comparison Controls- What is kept constant throughout the experiment

Good luck on the test!
