Biology Test #3

The solution with a lower concentration of solute compared to the cell in it.

The solution with a higher concentration of solute compared to the cell in it.

When a cell expends energy to move molecules or ions across a membrane

The passage of large or charged molecules down a concentration gradient through a carrier protein.

The movement of molecules across a membrane with out the use of ATP.

Carbohydrates from different cell can stick together, to make the cell stick together.

1. Enzymes 2. Cell recognition 3. Cell signaling 4. Transport

The passage of water from a region of high water concentration to a region of low concentration.

Hypotonic

Carbs identify the type of cell.

Phospholipid

Embedded in the phospholipid bilayer

Attached to embedded proteins or phospholipids.

The build up of lipids, proteins, and carbs.

Thin flexible selectively permeable bilayer.

1. do not have chloroplasts 2. no cell wall 3. have a membrane 4. small vacuole 5. can be circular shaped

x*x*6*8

1. All living organisms are made of cells. 2. Cells are the basic unit of structure, function, and physical aspect.

Photosynthesis occurs here

Over all movement

Water storage organelle found in plants

Build polypeptides (proteins)

More recent and complex. They are also 2.5 billion years old.

A series of membrane sacs that modify, package and route molecules to their next destination.

The bigger the volume the harder it is to get nutrients and waste in and out of the cell.

Break down waste

Sphere

Turns food energy into ATP

It is 3.5 billion years old. Oldest cell.

Bacteria

Contains DNA

x*x*6*64

The net movement of particles from an area of high concentration to an area of low concentration across a membrane.

Site of ribosome synthesis

1. Have chloroplasts 2. Use photosynthesis to make food. 3. Have a cell wall. 4. Large vacuole 5. rectangular shaped

Composed of microfilaments and microtubules

Site of lipid production and calcium regulation
