Life forms/ Domains and Kingdom

Classification

based on observable characteristics such as structures (anatomy, cell biochemical) of development, genetics, and sometimes behavior

often shows relatedness among organism

prokarote

–lacks nuclear membrane/ nucleus (genetic material free-floating), no membrane-bound organelles

eukaryote

–contains nucleus which has a nuclear membrane surrounding genetic material, has membrane-bound organelles

nuclear envolope

membrane that surrounds cell’s nucleus in eukaryotic cells

cell wall

outer layer, gives shape to & protects cell, can be made of different materials, not always present

cell/plasma membrane

–encloses cell and allows materials to enter/exit cell

autroph

makes organic food molecules

heterotroph

–cannot make organic food molecules, must obtain them

photosynthetic

     type of autotroph that makes organic food molecules using energy from sunlight

external digestion

type of heterotrophic process in which one organism dissolves another organism externally and then brings the dissolved materials inside

ingesiton

type of heterotrophic process in which one organism takes body parts of or wastes from another organism into its digestive tract for internal break down

flagella

tail like structure

cillia

many hair like structure

contractile fibrils

within organism, get smaller to create movment

ameboid (pseudopodia)

fake “foot” that oozes outward

multicellular

individual cells in an organism are coordinated, dependent.  Cells are specialized & can differ from one another.

unicellular

one celled

colonial (filamentous and Gobular)

contains many cells and they are all similar.  Filamentous colonial – same cell in a line    globular colonial- same cell in a blob
