➢ 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.
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
