Cell organelles keep us alive! Mitochondria and Chloroplasts They allow the cell to breathe (respiration) and gives the cell energy, just like our lungs do for us.
Lysosomes They are only in plant cells, and Much like our intestines, lysosomes break down materials in the cell and get rid of waste.
Nucleus Much like the brain, this is the control center and tells the cell what to do. How else would you know how breathe when you are not “thinking” about it? Cell Membrane Much like skin, the cell membrane is flexible protection allowing only certain things in and out. Vacuole Much like your stomach, the vacuole stores water and other materials for the cell until it is ready to be used.
QUIZ TIME!
1. Which picture represents an animal cell? A
B
The answer is A
Think of the cell membrane of an animal call like a plastic bag. It holds everything inside of the cell, yet it is flexible with tiny holes which allow some things to pass in and out.
2. Which part of the human body is much like the mitochondria and chloroplast? Hint: This is how the cell creates energy
Brain
Lungs Stomach Intestines
The answer is… Mitochondria and Chloroplasts Allows the cell to breathe (respiration) and gives the cell energy, just like our lungs do for us.
3. Why is the vacuole so much larger in plant cells than in animal cells? A. It is what makes plants green. B. It holds lots of water for the plant and gives the plant structure. C. Animal cells don’t need a vacuole. D. Vacuoles get rid of waste and plant cells have more waste.
The answer is B Animal cells do have vacuoles, but the Vacuole in the plant cell is much larger. It holds water, food and sometimes waste to protect the rest of the cell. The large size of the vacuole also gives the plant its structure, which is why a plant will get droopy if it needs water.
4. These images come from the same type of cell, but what kind of cell?
The answer is plant cells
5. Which arrow is pointing to the ROUGH endoplasmic reticulum on this animal cell? Hint: This is one way the cell makes new materials
B A
The answer is B B A
B is pointing to the ROUGH endoplasmic reticulum. You can tell because it has little black dots representing the robosomes that are attached to it. The ribosomes create proteins and the ER processes them.
