GRADED QUESTIONS AND ANSWERS
Science
Cell
➢ Cell: basic organizational unit of all living things. One thing
in common is they all have membranes (phospholipids).
➢ Cell structure organization: All cells contain DNA, and RNA &
can synthesize proteins. Consists of nucleic acids, cytoplasm, and
cell membrane.
o Tissues: Cells that are grouped together
o Organs: Tissues that are grouped together
o Systems: Organs that are grouped together
o Organism: A complete individual
➢ Nuclear parts of a cell
o Nucleus: contains chromosomes, & regulates DNA of the
cell. Defining structure of eukaryotic cells (they all have
nucleus). Passes genetic traits between generations. Contains
nuclear envelop, nucleoplasm, nucleolus, nuclear pores,
chromatin, & ribosomes.
o Chromosomes: thread like rods of DNA. Short
deoxyribonucleic acid, DNA is the genetic material that
stores information about the plant/animal.
o Chromatin: DNA & Protein makeup chromosomes
o Nucleolus: Proteins, small/round doesn’t have
membrane. Protein synthesis, synthesizes & stores RNA.

GRADED QUESTIONS AND ANSWERS
o Nuclear envelope: Encloses structures within nucleus. Made
of lipids.
o Nuclear pores: Exchange materials between the nucleus
* cytoplasm
o Nucleoplasm: Liquid like cytoplasm, within nucleus.
Cell Membranes
,ATI TEAS BIO EXAM, STUDY GUIDE 100% A+
GRADED QUESTIONS AND ANSWERS
➢ Cell Membrane (Plasma membrane): Semipermeable membrane of
lipids and proteins. Made of phospholipid bilayer, hydrophilic ends
of the outer layer facing the external environment, the inner layer
facing inside the cell, hydrophobic ends facing each other.
o Hydrophilic: Water loving, can dissolve water
o Hydrophobic: Hates water, can’t dissolve water
➢ Selective Permeability
o Selective Permeability with regards to size, charge,
and solubility.
➢ Cell structure
o Ribosomes: synthesize proteins from amino acids.
o Golgi apparatus: synthesize materials like proteins that are
transported out of the cell. Near nucleus & consists of layers
of membranes.
o Vacuoles: Sacs used for storage, digestion, and waste
removal. One large in plant cells/ Animal cells are small or
have numerous.
o Vesicle: Has membrane, & can move materials within the cell.
o Cytoskeleton: Microtubules that shape and support the cell.
o Microtubules: Part of cytoskeleton & help support cell.
Made of protein.
o Cytosol: Liquid material within the cell. Mostly water &
had floating materials.
o Cytoplasm: Cytosol & organelles found within the plasma

GRADED QUESTIONS AND ANSWERS
membrane, not within nucleus!
o Cell membrane: Barrier that keeps materials out of
cell. Determines what’s allowed in and out.
o Rough Endoplasmic reticulum: Ribosomes on the
surface, produce & store proteins
o Smooth Endoplasmic reticulum: Helps store lipids & proteins.
