7th Grade Mid Term Review:
The following is a study guide for the midterm. The test will include the metric system through
mitosis and meisois. You are responsible for knowing all the vocabulary terms for each section.
Under the “know” section for each topic you should know those topics and be able to answer
questions about them.
Answer the questions at the end of the study guide as well as the questions posted (you will
find the questions in the small green textbook)
Metrics:
Know: What are the 7 prefixes and the order in which they appear. What are the 3
bases? How to convert from one prefix to another.
Discovering the Cell:
Vocabulary: Cell, microscope, cell theory, eukaryotic, prokaryotic
Know: What characteristics make up a prokaryotic and a eukaryotic cell (examples of
each) 5 scientists who were involved in the cell theory and what they discovered. Three parts of
the cell theory
Parts of Cells/ Specialized cells:
Vocabulary: organelles, cell wall, cell membrane, nucleus, nuclear membrane,
nucleolus, cytoplasm, mitochondria, rough endoplasmic reticulum, smooth endoplasmic
reticulum, ribosomes, vacuole, vesicle, cytoskeleton, lysosome, golgi body, chloroplast,
chlorophyll, red blood cell, white blood cell, nerve cell, leaf cell, root cell
Know: What each of the organelles form and function is. Which organelles are in plant
cells and which are in animal cells. The 5 specialized cells, what their form is and what they do.
Chemical Compounds in Cells:
Vocabulary: Element, compound, organic compound, inorganic compound,
carbohydrate, lipid, protein, nucleic acid, amino acids, enzyme, DNA, RNA
Know: The difference between an organic compound and an inorganic compound. 4
examples of organic compounds, elements that make then up, what they do and examples.
What is water and why is it important for all living things.
Cell and its Environment:
Vocabulary: Selectively permeable, active transport, passive transport, diffusion,
osmosis, hypotonic, hypertonic, isotonic, facilitated diffusion, engulfing, endocytosis, exocytosis
Know: What diffusion and osmosis are. EGG LAB(what happened to each egg and why)
How substances flow into or out of cells based on the concentration of materials inside and
outside of them.
Photosynthesis:
Define Vocabulary – photosynthesis, autotroph, heterotroph, pigments, chlorophyll,
stomata, chloroplasts,
Know: equation for photosynthesis, how leaves get energy, Why do living things need
energy, stages of photosynthesis, Where energy comes from.
Respiration:
Define Vocabulary – respiration, fermentation (alcoholic and lactic acid)
Know: Equation for respiration, what respiration is, differences between respiration and
photosynthesis, types of fermentation, How respiration stores energy, stages of respiration.
Cell Division:
Mitosis: Define Vocabulary – cell cycle, interphase, replication, mitosis, chromosomes,
cytokinesis, spindle fibers, centrioles, sister chromatids, prophase, metaphase, anaphase,
centromere, chromatid, nuclear membrane, telophase, nucelous, asexual reproduction, diploid,
budding, regeneration, fission
Know: What happens in the stages, cell cycle, what chromosomes are, be able to
identify and label pictures of stages, what spindle fibers do, results of mitosis
