3 PROKARYOTIC CELLSProkaryotic Cells – Single-celled organisms that do not have membrane-bound internal structures; no nucleus; simple cells with very little organization of the materials inside. EXAMPLE: bacteria
4 EUKARYOTIC CELLSEukaryotic Cells –cells that have organelles; contain nucleus; cells with organized structures EXAMPLES: Protists, Animals, Plants, and Fungi
6 CYTOPLASMCytoplasm – All cells contain cytoplasm. It is a clear gel-like fluid (liquid) which takes up most space inside the cell, where many cell reactions and where organelles are located
7 NucleusNucleus – Only eukaryotic cells have a nucleus. control center of cell; brain of cell; usually located near center of cell; controls cell activity; contains DNA (deoxyribonucleic acid).
8 ___ _______Cell membrane – All cells have a cell membrane. It is the protective barrier of the cell that holds it together. It lets good material in and bad material out.
9 Cell WallCell Wall – stiff outer barrier of a plant cell, outside of the cell membrane, mostly made up of cellulose, provides extra support and gives it shape; surrounds cells of plants, fungi, and bacteria
12 The 3 Domains of Life Domains are the first and the broadest of classifications. One domain is Archea, which is composed of the organisms in the Kingdom Archeabacteria.Bacteria is the second prokaryotic domain and is also composed of single kingdom Eubacteria.The third domain, Eukarya, contains all four of the eukaryotic kingdoms: Animalia (animals), Fungi (fungi), Plantae (plants), and Protista (protists).
15 The Kingdoms of LifeBiologists have further classified living things into six groups called Kingdoms.Biologists group organisms into six Kingdoms based on the following:Cell TypeOrganisms are either prokaryotes or eukaryotes.Cell NumberOrganisms are either unicellular or multicellular.NutritionOrganisms are either autotrophs or heterotrophs.
16 6 KINGDOMSKingdom – a system used to classify and organize different organisms found on Earth into groupsArcheabacteriaEubacteriaProtistaFungiPlantaeAnimalia
17 Kingdom Archaeabacteria Contains all of Domain Archae.Archaebacteria are prokaryotes that live in very harsh conditions.
18 Kingdom Eubacteria Contains all of Domain Bacteria. Bacteria are prokaryotes and have no internal nucleus.Bacteria are found in practically every environment on Earth.
19 Kingdom Fungi Single or multi-celled organisms Reproduce by spores Heterotrophs that eat dead or living organisms - decomposerYeasts, molds, mushrooms
20 Kingdom Plantae multi-cellular organisms surrounded by a cell wall make their own food (photosynthesis)EukaryotesMosses, ferns, conifers, and flowering plantsFlowering plants produce seeds in flowers; conifers make seeds in cones; mosses and ferns reproduce by spores
21 Kingdom Animalia multi-cellular organisms eukaryotes get energy from other organisms (omnivores)
22 Kingdom Protista mostly single-celled organisms eukaryotes Some feed on other organisms; ex. Amoeba and paramecium (heterotroph)Some make their own food (photosynthesis); ex. Euglena and algae (autotroph)
