Archabacteria Kingdom
ancient bacteria, live in harsh environments, unicellular, prokaryotes (no nucleus)
Eubacteria Kingdom
common or true bacteria, unicellular, prokaryotes (no nucleus)
Animal Kingdom
multicellular, eukaryotes (have nucleus), heterotrophs (eat food), most can walk/swim
Plant Kingdom
multicellular, eukaryotes (have nucleus), autotroph (make food)
Protist Kingdom
univellular (one cell), eukaryotes (have nucleus), found in water
Fungi Kingdom
multicellular, eukaryotes (have nucleus), decomposers
cell membrane
a thin membrane around the cytoplasm of a cell (controls what enters and leaves the cell)
circulatory system
heart, blood, arteries, veins; moves blood, blood contains oxygen, nutrients, and waste
endocrine system
pituitary gland, thyroid; produces hormones; a chemical communication system (using hormones) by which messages are sent through the bloodstream; helps body maintain homeostasis (balance)
digestive system
mouth, esophagus, stomach, intestines; breaks down and absorbs nutrients/water
excretory system
kidney, bladder; EXIT, remove waste
immune system
white blood cells, bone marrow, thymus gland, spleen; protect the body from disease/fight infections
integumentary system
skin, hair, nails; protection
nervous system
brain, spinal cord, neurons (nerve cells); take in info about internal and external environment
reproductive system
organ system which functions in creating offspring (penis and testes in males; ovaries, uterus, and vagina in females), sperm and egg
respiratory system
lungs, nose; inhale oxygen, exhale carbon dioxide
muscular system
muscles, movement
skeletal system
bones; support, produce blood cells
DNA (inherited through sperm and egg cell)
genetic material that controls a cells activities and determines which protiens are made
mitochondria
powerhouse of the cell, organelle that is the site of ATP (energy) production
food→ATP (energy)
cellular respiration
nucleus
a part of the cell containing DNA and RNA and responsible for growth and reproduction (controls cell)
mutation
any event that changes genetic structure, change in DNA
replication
the process whereby DNA makes a copy of itself before cell division; copy machine
transcription
the organic process whereby the DNA sequence in a gene is copied into mRNA (copies DNA's info into mRNA)
translation
the process whereby genetic infomation coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm; protein is made from mRNA (happens in robosome)
