Prokaryote vs Eukaryote (Plant and Animal) Cells - Kathy Egbert | Library

Comparing and contrastinng Prokaryote and Eukaryote cells (abt 4 mins)

Being small and simple can be an advantage because prokaryotic cells can reproduce quickly and efficiently. This allows these simple organisms to adapt to environmental changes easier than eukaryotic cells. This increases "fitness" - their ability to survive and reproduce in spite of changes in environmental conditions.

Knowing the prefix, suffix and root meanings of words increases your vocabulary. Eukaryote literally means

If you haven't already done so, add this information to your class notes

Since there is only two types of cells, characteristics shared by both prokaryotic and eukaryotic cells means the same as saying that all cells have these characteristics.

All cells have 3 things in common:

- genetic material (DNA)
- cell membrane
- cytoplasm

Compare & Contrast Prokaryotic vs Eukaryotic Cells

If you haven't already added this information to your class notes, do it now by
creating a table or copying the Venn diagram to your notes.

Knowing the differences between prokaryote and eukaryote cells is what helps you distinguish and identify the type of cell. A couple of clarifications to the Venn Diagram:

prokaryotes have a "nucleoid region" where the DNA is located in the cell, however it is not considered a nucleus because it doesn't have a membrane around it
we refer to the organelles in Eukaryotic cells as "membrane-bound organelles", meaning that the individual organelles are surrounded by a membrane

Practice - test yourself using the following three pictures of cells. Select
either prokaryotic or eukaryotic cells.

Figure A (above) is a picture of staphylococcus aurea bacteria. It is a

Figure B (above) is a picture of the bacterium E. coli. It is a

Figure C (above) is a picture of epithelial cells (cells that line the surface of organs and tissues in humans). It is a

Comparing & Contrasting Plant and Animal Cells (abt 2 mins) There are two types
of Eukaryotic cells: plant and animal. While watching the video clip, add the
information that distinguishes plant cells from animal cells to your class
notes.

Does your list look something like this?

Plant Cells	Animal Cells
autotrophs: make own food cell wall: gives structure & support, controls water loss (see pg 79 in textbook) chloroplast; organelle for photosynthesis, filled with green pigment called chlorophyll (see pg 79 in textbook) large central vacuole: regulates water, nutrient storage & sometimes serves as a storage for poison	heterotrophs: get their food from eating other things in the environment centrioles: thought to help cells during cell division (see pg 78 in textbook) lysosomes: contain enzymes that help to protect and break down damaged or worn-out cells and eat invading bacteria or viruses (see pg 78 in textbook)

Similarities: makes proteins, grows, develops, and reproduces

Now that you know a little about prokaryotic cells and eukaryotic plant and animal cells. Try this question: Suppose a certain poison kills human cells by blocking pores in the membrane that surrounds the nucleus. Explain why the poison (would or wouldn't) work on prokaryotic bacterial cells.

Practice identifying the structures inside cells and their function.
Practice the differences between prokaryote and eukaryote cells.
Practice the differences between plant and animal eukaryote cells.
