Characteristics of living things
1.living things respond to their environment 2.living things need energy 3.living things grow 4.living things reproduce 5.living things must get rid of waste
What are organs made of
Living tissues that are made up by cells
What are tissues made up of
Cells
What do cells need to work properly
Oxygen and food
What is science
Both a body of knowledge and a process for gaining more knowledge about the world around us
What are three ways molecules pass through the cell membrane
A)defusion B) Osmosis C) actice transport
Substances always move in an area of…
High concentration to low concentration
Cell theory
A main idea of modern biology includes the cell is the basic unit of life, all organisms are composed of one or more cells, all cells come from other living cells
Plant versus animal cells
Plant cells have cell walls and chloroplast plant cells are more rigid and boxlike
Prokaryotic cells
Type of cell who’s organelles are not surrounded by membranes
Eukaryotic cells
Are surrounded by membranes
Animal cells have…
Lysosome, Golgi body, nucleus, vacule, mitochondria, endoplasmic reticulum , ribsome, cell membrane, cytoplasm
Plant cell contains…
Mitochondrion, cytoplasm, endoplasmic reticulum , chloroplasts,ribsome , Golgi body, cell wall, cell membrane, vacuole, nucleus.
Bacteria
Prokaryotic cells over 5000 different types or species of bacteria that have been indefied 10% of your mass is bacteria
Viruses
Not alive, HIV, chickenpox, cold sores, or the flu, nonliving particles that produce only when they are inside a Host cell, have no nucleus or any other organelles
Mitochondria
Produces energy by Cellular respiration
Vacuoles
Are like storage containers they store waste that the cell produces plant cells have larger vacuoles because they produce more waste
Cytoplasm
Jelly like substance it contains organelles water and other life supporting materials
cellular respiration
Food plus oxygen equals carbon dioxide plus water plus energy
