CELL BIOLOGY TEST REVIEW

TOPICS TO KNOW / THINGS I KNOW / THINGS I NEED TO KNOW
CELL / Cell theory, types of cells , 17 organelles
ORGANIZATION OF CELLS / Cell , tissues, organs, organ systems, organisms
PROKAYOTIC CELLS / No nucleus, single cell, DNA, cytoplasm
no membrane bound organelles, bacteria, primitive
EUKARYOTIC CELLS / Have nucleus, single/multi cell, DNA,
have membrane bound organelles, more complex
CELL THEORY / All living things made up of cells
Cells are the basic unit of structure and function
Cells come from other cells
ANIMAL CELL / Centrioles in animals only
Vacuoles are smaller in animals
Outer covering is a cell membrane
PLANT CELL / Vacuoles are larger (central vacuoles)
Chloroplasts and Cell walls in plants only
CELL MEMBRANE / Surrounds entire cell, holds in cytoplasm and all organelles,
Things in and out of cell
CYTOPLASM / Jelly-like fluid that fills cell,
Cell activity occurs here
NUCLEUS / Control center,
contains nucleolus and chromosomes
NUCLEAR MEMBRANE / Surrounds the nucleus
Allows materials to move in and out of nucleus
NUCLEOLUS / Helps to make ribosomes
CHROMOSOMES / Contain hereditary information , DNA, contains gene, code of life
ROUGH ENDOPLASMIC RETICULUM / Canals that proteins, and other materials travel through within cell
SMOOTH ENDOPLASMIC RETICULUM
RIBOSOMES / Make protein
GOLGI APPARATUS / Packages materials for cell.
VESICLES / ‘pods’ that contain material for transport
VACUOLE / Store water and food for cell
MITOCHONDRIA / Creates energy for the cell
LYSOSOMES / Break down material for cell
CENTRIOLES / Help with reproduction of animal cells
CELL WALL / Thick structure that surrounds plant cell, provide shape and protection for cell
CHLOROPLASTS / Produce food for plant through photosynthesis.
ACTIVE TRANSPORT / COST ENERGY
SUGAR OTHER MOLECULES
ENDOCYTOSIS / MOVEMENT INTO CELL BY CELL MEMBRANE
EXOCYTOSIS / MOVEMENT OUT OF CELL BY CELL MEMBRANE
PASSIVE TRANSPORT / NO ENERGY (H20 AND O)
Examples: osmosis and diffusion
OSMOSIS / TYPES OF PASSIVE TRANSPORT
WATER CELL MEMBRANE
Moves from a high concentration to a low concentration
DIFFUSION / TYPES OF PASSIVE TRANSPORT
Moves materials from a high concentration to a low concentration
HYPOTONIC / Solution that contains a higher concentration of water than solute
(causes cells to expand)
HYPERTONIC / Solution that contains a lower concentration of water than solute
(causes cells to shrink)
ISOTONIC / Solution that contains an equivalent amount of water to solute
(cells remain unchanged)
