What are the 6 characteristics of living things?
Uses energy, reproduces, responds to stimulus, contain common chemicals, made of cells, grows and developes.
Difference with stimulus and response
Stimulus is what triggers the response.
Common chemicals all living things are composed of and their purpose #1
Protein, fat+Carbs, water, and DNA
Protein purpose
Building blocks for cells
Fat+carbs purpose
Fat+Carbs= Provide energy for cells
Water purpose
Water= Helps cells transport and use substances
DNA purpose
DNA= The instructions for doing and building things
Cell theory statement 1
All living things are composed of cells
Cell theory statement 2
Cells are the basic unit of structure and function in all living things
Cell theory statement 3
All cells are produced from other cells.
Cell membrane
Cell membrane= Surrounds and protects cells: Gatekeeper
Cytoplasm
Cytoplasm= Fluid that fills cells (holds organelles)
Nucleus
Nucleus= Surrounds and protects DNA
Mitochondria
Mitochondria= Site of energy production by cellular respiration
Chloroplast
Chloroplast= Site of photosynthesis
Cell wall
Cell wall= Surrounds and protects plant cells+ Very rigid
Vacuole
Vacuole=Stores water
Ribosomes
Ribosomes= Makes proteins
Edoplasmic reticulum
Endoplasmic reticulum= Where proteins and fats are made
Plants v.s. Animal cells
Only plant cells have chloroplasts and cell walls.
Prokaryote
Has no nucleus and membrane bound organelles
Eukaryote
Have a nucleus that surrounds and protects the DNA+ Has membrane bound organelles
Are humans Eukaryote or Prokaryote celled
Eukaryote
what is the difference between plant and animal cells
Plant cells have a cell wall in addition to a cell membrane, and have a chloroplast
Similarity with Pro and Eukaryotic cells
Have cell membrane, ribosomes, DNA, and Citoplasm.
