AP Bio Unit 2 Review

Front

What structure allows plant cells to connect and communicate?

Back

Plasmodesmata

Front

What distinguishes Trichodina from all prokaryotes?

Back

Trichodina has a nucleus.

Front

What would you expect to find in the membrane composition of an organism living in a cold climate?

Back

Many unsaturated fatty acid chains to prevent tight packing of the phospholipids at low temperatures.

Front

What do phospholipid heads contain?

Back

Phosphate group and glycerol.

Front

What is a function of the Golgi complex when part of its membrane pinches off?

Back

To deliver proteins to other locations in the cell.

Front

Define plasmodesmata.

Back

Plasmodesmata are channels that allow communication and transport between plant cells.

Front

What is the significance of unsaturated fatty acids in cell membranes?

Back

They prevent tight packing of phospholipids, maintaining membrane fluidity at low temperatures.

Front

What is the role of the Golgi complex in a cell?

Back

The Golgi complex modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is a eukaryotic organism?

Back

An organism whose cells contain a nucleus and other organelles enclosed within membranes.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.
