Where do you find DNA in a eukaryotic cell

the nucleus

100

Phosphate heads are ______

Tails are ________

hydrophilic

hydrophobic 

100

Hypertonic is ______

Hypotonic is _________

high solute, low solvent

low solute, high solvent

200

State the 4 features shared by all cells

1. cytoplasm

2. plasma membrane

3. DNA

4. Ribosomes

200

Where does transcription and translation occur in a eukaryotic cell

Transcription in nucleus

translation in cytoplasm

200

Difference between integral and peripheral proteins

integrals can go all the way or halfway into the bilayer while peripheral are only on the surface of the bilayer or attached to the hydrophilic part of an integral protein

200

Osmosis is _______

Passing of water from a low conc. to a high conc. through passive transport

300

What is the role of the lysosomes

They are vacuoles that contain enzymes which digest large molecules 

300

in a eukaryotic cell, DNA is transcribed into _______. mRNA then is translated by _______ into _________. 

mRNA

80S ribosomes

proteins 

300

Channel proteins are used in ______

Facilitated diffusion 

300

Animal cells in a hypertonic solution undergo ______

crenation

400

3 differences between animal and plant cells 

-animals have centrioles while plants dont

-plants have a cell wall while animals dont

-plants have plastids (chloroplasts) while animals dont

-animals could have flagella while plants donts

400

What is the importance of compartmentalization

Organelles dont disrupt each other's functions. 

Nucleus protects transcription process from metabolism in the cytoplasm 

400

Why is ATP used in active transport?

particles are moving against the concentration gradient
