What organelle within the cell is the "ultimate packaging center" because it receives items from the transport vesicles pinched off from the ER, contains enzymes that can modify molecules, and sorts the materials it receives to be sent around the cell.

• Golgi Apparatus

• Mitochondria

• Endoplasmic Reticulum

• Chloroplasts

If a particle is too large to pass through the cell membrane, it must move through via _________.

• Protein doorways

• Molecules

• Low concentration

• High concentration

1. T/F: In passive transport, the movement of particles across a membrane requires energy. (a)  

2. T/F: Endocytosis is a process by which a cell membrane surrounds and takes in material from the environment.​ (b)  

3. T/F: A membrane that allows only some materials to pass through shows selective permeability. ​ (c)  

• False

• True

In ​ (a)   , materials move with the concentration gradient without assistance. In ​ (b)   , materials also move with the concentration gradient but they need the assistance of a carrier protein.

• simple diffusion

• facilitated diffusion

​ ​ (a)   does NOT require energy.

• passive transport

• active transport

• endocystosis

• exocytocisi

Passive Transport ​ (a)   energy and particles move from ​ (b)   concentration areas to ​ (c)   concentration areas.

• requires

​ (a)   ​ (b)   and ​ (c)   are all types of ​ (d)  

• diffusion

• osmosis

• facilitated diffusion

• passive transport

• endocytosis

• exocytosis

Diffusion is the movement of molecules from an area of ​ (a)   concentration to an area of ​ (b)   concentration.
