Bacterial Cells
What are the appendages that allow bacteria to stick to surfaces?
Pili
What is the pigment found in chloroplasts?
Chlorophyll
Processes and packages proteins and lipids.
Golgi apparatus
Diffusion is the movement of particles from __________________________.
High to low concentration
Active transport requires energy in the form of ____________.
ATP
Where can small segments of DNA be found in bacteria?
Plasmids
What are cell was made of?
Cellulose
Which organelle contains digestive enzymes?
Lysosome
What can increase the rate of diffusion?
How do cells expel large amounts of materials?
Exocytosis
What is the difference between the nucleus and the nucleoid?
Nucleoid is free-floating DNA in cytoplasm, nucleus contains DNA in a protective membrane
What is the function of the amyloplast?
Storage of starches (polysaccharides)
What exists as either free or bound?
Ribosomes
A blood cell placed in fresh water is _________________ by comparison.
Membrane pumps move materials from ________________________.
Low to high concentration
What outer layer do bacterial cells possess that other organisms do not?
Capsule
Up to 90% of a plant cell can be taken up by the ___________________.
Vacuole
If there was a malfunction in the packaging and modification of proteins, which organelle is likely affected?
Rough ER
Polar and large molecules require ________________________ to diffuse through the cell membrane.
Transport Proteins
Which form of active transport is specially targeted for specific molecules/substances?
Receptor-Mediated Endocytosis
Bacterial cells have less organelles than eukaryotic cells. But, what structures do they all possess?
Cell membrane, cytoplasm, and ribosomes
What is the relationship between chloroplast and mitochondria?
Chloroplast makes sugar, mitochondria breaks it down
If the cell membrane needs repair, what organelle can produce the necessary materials?
Smooth ER
Why does O2 diffuse into the cells and CO2 diffuse out?
Cells use O2 (low concentration) and produce CO2 (high concentration).
In both endocytosis and exocytosis, the vesicles involved are made of ________________.
