Question

complete the table to describe the organisms shown in the micrographs above.
characteristic\tonion plant\tdiatom
essential processes happen in a cell\t□\t□
a cell is its basic unit of structure\t□\t□
made up of one cell\t□\t□
made up of many cells\t□\t□

Explanation:

To solve this, we use cell theory and knowledge of unicellular/multicellular organisms:

Step 1: Analyze "essential processes happen in a cell"

All living organisms (onion plant, diatom) have essential life processes (like metabolism) occurring in cells. So both get a check (✓).

Step 2: Analyze "a cell is its basic unit of structure"

Cell theory states the cell is the basic structural unit of all living things. Both onion (plant) and diatom (algae) follow this. So both get a check (✓).

Step 3: Analyze "made up of one cell"

• Onion plant: Multicellular (many cells), so no (✗).
• Diatom: Unicellular (one cell), so yes (✓).

Step 4: Analyze "made up of many cells"

• Onion plant: Multicellular, so yes (✓).
• Diatom: Unicellular, so no (✗).

Characteristic	Onion plant	Diatom
a cell is its basic unit of structure	✓	✓
made up of one cell	✗	✓
made up of many cells	✓	✗

(Note: Use checkmarks or "✓"/"✗" in the table cells as needed.)
