1 The smallest unit of life

2 Molecules move from area of higher concentration to lower concentration

3 Cells without a nucleus and membrane bound organelles
bacteria

4 Which molecule in the cell membrane?
Maintains fluidity Barrier to polar, large, and charged molecules Identifies the cell Channel Attachment site for cytoskeleton

5 Which organelle? Breaks things down and recycles them Makes proteins
Makes energy Photosynthesis Processes and packages Fluid of cell Control center Makes ribosomes Stores water and is large in the plant cell

6 Water molecules moving across a membrane from an area of higher water concentration to lower water concentration

7 Large (bulk) materials are leaving the cell via a vesicle

8 What are the 2 kinds of cell transport
What are the 2 kinds of cell transport? What is the difference between them?

9 A structure inside a cell that performs a specific function

10 Some things can pass through but others can not

11 Molecules moving down their concentration gradient with the help of a carrier or channel protein
