Name some similarities and differences between plant and animal cells.

1. 
   
   1. Both animal and plant cells have cell membranes that enclose the cell
   2. Both animal and plant cells are filled with cytoplasm a gel – like substance containing chemicals needed by the cell
   3. Both animal and plant cells have a nucleus, where DNA 8is stored. DNA controls many of the characteristics of living things. Inside the nucleus Is the nucleolus
   4. Both animal and plant cells, have ribosomes, protein builders of the cell
   5. Both animal and plant cells have mitochondria that toes oxygen to break down food and release the energy in food’s chemical bonds
   6. Both kinds of cells have vacuoles that contain food, water, or waste products. Animal cells usually have many more vacuoles than plant cells
   7. The cells of both plants and animals have endoplasmic reticulum, where a system of tubes process and transport proteins within cells
   8. The Golgi bodies in both plant and animal cells package proteins for distribution outside the cell
   9. Plant cells have cell walls that provide structure but animal cells do not.
   10. A few large4 animal cells have more than one nucleus, but plant cells always just have one.
   11. Plant cells have chloroplasts for photosynthesis but animal cells do not.
   12. Animal cells tend to have many small vacuoles. Mature plant cells have only one large vacuole.
   13. Animal cells have lysosomes, but plant cells do not.

what are cells?

the basic unit of life

Easy

100

what do skin cells do?

cover and protect

200

Name some differences between eukaryotic and prokaryotic cells

1. 
   
   1. Eukaryotic cells: Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. We have eukaryotic cells
   2. Prokaryotic cells: Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Most bacteria are prokaryotic

300

What is the plasma membrane?

Allows only certain things to get in and out of the cell - protection

400

What are organs?

Groups of similar tissues working together

what are organelles?

• One of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform specific function

• What does DNA stand for?

Deoxyribose nucleic acid

Hard

100

what is taxonomy?

study of the classifications of organisms

200

. Name examples of fats

Butter, cheese, red meats, etc.

300

Name examples of carbohydrates.

sugars, starches, bread, etc.

400

• Name the important chemicals needed in the body.

Proteins, carbohydrates, fats

500

• What does it mean by phospholipid bilayer in the plasma membrane?

Has two layers of phospholipid - hydrophobic tails and hydrophillic heads

Random
