Intro to The Cell & its Parts! (Comparing Plant and Animal Cells)

Cells Cells are the basic units of structure & function of all living things…if it is alive it has cells… If it was once living it has dead cells!

Two “Types” of Cells There are 2 types of cells. There are only two differences between Plant & Animal cells…try to spot them by the end of the show Plant cells Animal Cells

Cell Differentiation There are 2 classes of cells we will learn (plant/animal), but there are many kinds of cells in each class. Each kind of cell has a DIFFERENT job to do…it specializes. I’m a Prison Cell! 

Different kinds of Cells

Cell Membrane Supports & protects the cell, Regulates what enters & leaves the cell Lipid Bilayer = 2 layers of fat It’s like skin with pores around your body! BOTH

Nucleus The control or information center of the cell Round usually found in the center of the cell. Contains DNA or Genetic Material. The cell’s Brain or Boss! BOTH

Chromosomes Chromosomes are inside the nucleus and are made of genes (DNA) Genes decide the cells traits and activities (heart cell, eye cell (color))

Cytoplasm Cytoplasm gives the cell support and shape It is the thick jelly-like substance that fills the area between the organelle. It holds the ORGANelles Like the liquid in soup with veggies as organelles. OR jello with fruit! BOTH

Mitochondria Mitochondria breaks down food molecules & releases energy. Bean shaped organelle filled with folded membranes. The cell’s POWER HOUSE! BOTH

Cell Wall Cell Walls are only in PLANT cells! Protects & provides structure & shape. It makes the cell strong & rigid. Thicker membrane that lies outside of the cell membrane. Like cartilage in your ear and nose. What makes plants stand up.

Chloroplasts Chloroplasts are only in PLANT cells Traps sunlight and makes food for the plant cell in a process called Photosynthesis! Green, contains chlorophyll (pigment). Long oval shape. Like a solar oven.

Vacuoles Vacuoles store water, food, & waste in the cytoplasm. Fluid filled sacks. Large in plants, multiple small ones in animal cells..

What’s the Difference? So what are two things that Plant cells have that animal cells don’t? Chloroplasts & Cell Walls ?
