Q

I define the boundaries of a cell and regulate the passage of substances into and out of the cell

A

Plasma membrane

2
Q

What does the plasma membrane consist of?

A

Phospholipids, cholesterol, and protein

3
Q

Where is all of the cells genetic information located?

A

Nucleus

4
Q

Gel like substance that fills the space between the plasma membrane and the nucleus

A

5
Q

I fill the cytoplasm and perform specific tasks in metabolism

A

Organelles

Q

I make and package proteins and lipids, I’m a network of membranous canals and curving sacs

A

Endoplasmic reticulum

7
Q

What is the function of rough ER?

A

Contains ribosomes - makes and packages proteins which move through canals towards the Golgi apparatus

8
Q

What is the role of the smooth ER?

A

Assembles and packages certain lipids and carbohydrates

9
Q

We are small sac-like structures surrounded by a single membrane and contain strong digestive enzymes, which when released, can break down worn out organelles or food. Who are we?

A

Lysosomes

*garbage disposal - remember “Lysol” kills bacteria

Q

I prepare and temporarily store protein which can then leave the cell via vesicles. Who am I?

A

Golgi apparatus

12
Q

These bundles of microtubules play a role in cell division

A

Centrioles
