Types of Cells

Learning Target LT BI1.c*: I can identify, differentiate, and illustrate the similarities and differences between prokaryotic cells and eukaryotic cells (including those from plants and animals).

There are many varieties of cells…

Cells fall into 2 main categories: Prokaryotes Eukaryotes

Cells fall into 2 main categories: Prokaryotes Eukaryotes

Prokaryotes Commonly known as bacteria Small and simple No membrane-bound organelles DNA is in cytoplasm No nucleus Single-celled only

These are prokaryote E. coli bacteria on the head of a steel pin.

Eukaryotes Include both plant and animal cells Large and complex Contains membrane-bound organelles DNA is in the nucleus (chromosomes) Single-celled or multicellular organisms

Eukaryote cells can be multicellular The whole cell can be specialized for one job cells can work together as tissues Tissues can work together as organs

Examples of specialized euk. cells liver cell: specialized to detoxify blood and store glucose as glycogen.

Similarities Both prokaryotes and eukaryotes: Have a cell membrane Contain cytoplasm And contain DNA

CST Practice Question #1

TYPES OF EUKARYOTES

Eukaryotes can be divided into 2 main categories: Plant Cells Animal Cells

What are 3 differences between these 2 cells?

Cells fall into 2 main categories: Prokaryotes Eukaryotes

Plant vs. Animal Cells Plant cells have cell walls. Animal cells do not. Plant cells have large, central vacuoles. Animal cells also have vacuoles, but they are much smaller. Plant cells have chloroplasts. Animal cells do not.

Structures found in plant cells Cell wall very strong made of cellulose protects cell from rupturing

Vacuole huge water- filled sac keeps cell pressurized stores starch

Chloroplasts filled with chlorophyll turn solar energy into food energy
