Objective/Why is this important?

• EQ: how do our cells help us survive? What do our cells need to survive?

• Objective: We will be able to identify the key organelles that are only in plant cells and only animal cells in order to compare and contrast the different functions.

Agenda

• Do Now & Review• Updates/Homework• INM: organelles in animal cells in plant cells• Practice: fill in the chart• Exit Ticket

Updates

• Quiz next time about cell organelles their functions

IN PLANT CELLS ONLY• Cell Wall

• Chloroplasts

Cell Wall

-Outer layer of plant cell that surrounds the cell membrane-Thick and rigid-Provides protection & support

Cell wall is like the armor of a cell

Cell wall

Chloroplast • Bean shaped organelle with coils on the inside• Uses light energy to create food for plant• Site of photosynthesis

The chloroplast is like a mini oven

•IN ANIMALS CELLS ONLY

•Lysosomes•Centrioles

Lysosome

• Circular bowl shaped organelle• Breaks down (digests) and disposes of any waste in the cell.

The Lysosome is like a garbage truck

Centrioles

• Involved in cellular division
