Eukaryotic Cells: Animal vs Plant Ms. Klinkhachorn October 13, 2009

Review: Prokaryotes vs Eukaryotes

Cells Two Types: – Prokaryotes – Eukaryotes Animal Cell Plant Cell

Animal Cells - Centrioles Centrioles – Involved in cell division – Two pairs, each piece at right angles to the other

Plant Cell

Plant Cells - Vacuoles Vacuoles – Membrane bound compartment for temporary storage of materials Pigment in petals Poisons in the leaves – Large central vacuole in plants – Not common in animal cells If they are there, they are very small

Plant Cells – Cell Wall Cell wall – Rigid structure located outside the cell membrane – Gives more support and protection – Porous and inflexible – Made of cellulose Most common organic compound on earth

Plant Cells - Chloroplasts Chloroplasts – Photosynthetic organelle Capture light energy and convert it to chemical energy – Double membrane – Contains the green pigment chlorophyll

Types of Animal Cells

Types of Plant Cells

Compare and Contrast Animal Cells Small or absent vacuoles No chloroplasts Nucleus at center of cell No cell wall Irregular shape Smaller in size Membrane-bound organelles Centrioles Plant Cells Large, central vacuole Chloroplasts Nucleus toward the side Cell wall Regular shape Larger in size Membrane-bound organelles No Centrioles
