Chapter 4 (2) Flashcards
Found in both prokaryotes and eukaryotes are
Plasma membrane
Ribosomes
Flagella & cilia
Only found in plant cells
Cell wall
Chloroplasts
Phospholipid bilayer describes
The plasma membrane of a cell
The cell membrane is
Hydrophilic
Hydrophobic
Has proteins with in it
Light microscope
Light passing through a specimen, low resolution
Scanning electron microscope (SCM)
Uses electrons to study external 3-D features of a specimen, high mag. & res.
Transmission electron microscope (TEM)
Uses electrons to study internal structures of cells, high msg. & res.
Ribosomes job is
They are the site of protein synthesis
Endoplasmic reticulum (ER) has how many types
2
Rough- ribosomes attach
Smooth- no ribosomes attach
What helps digestion and killing bacteria
Lysosomes think Lysol
Chloroplasts are
Only in plants
Give plants their green color
Perform photosynthesis
Mitochondria produce
ATP
Two types of cells 1st Eukaryotes
Eukaryotes =protists, plants, fungi,animals,humans
Prokaryotes = bacteria and archaea
Prokaryotes
Smaller than eukaryotes Older than eukaryotes No nucleus No organelles Have flagella and cilia
Similar to eukaryotes
Plasma membrane
Ribosomes
Cilia and flagella
Ribosomes
Ball of RRNA
Plasma membrane
Bubble around cell to keep everything in
Cilia & Flagella
To get around
Plants and animal cells have
Plasma membrane
Nucleus
Cytoplasm
Organelles
Plant cells have
Cell wall
Chloroplasts
Rough er
Synthesis membrane proteins
Synthesis secreted proteins
Smooth er
Synthesis steroids & lipids
Detoxification Of drugs & poison
Vacuoles
In plants
Stores organic nutrients such as proteins
Helps plant growth
Also found in protists
Cellular respiration
Converts energy of sugar and food into another form if chemical energy = ATP
Chloroplasts & Mitochondria
Both have their own dna
Both have been free living prokaryotes at one time
