Form and function of cells

There are different types of cells Eukaryotic –Animal –Plant Prokaryotic

Eukaryotic cells Contain a nucleus that holds all the DNA Has membrane bound organelles Complex: has many structures and parts. Animals and plants are eukaryotic cells.

Eukaryotic Animal cell  Animal cells lack cell walls (extra layer of protection) and chloroplasts (energy producers) and can not make their own food  Small vacuole (storage compartment)  Some have flagella (tail) & cilia (hairs) which is used for movement.

Energy conversion within an animal cell would be severely limited by removal of the cell’s — A mitochondria B chloroplasts C plastids D lysosomes

Eukaryotic Plant Cell Has chloroplasts that use sunlight to make energy Has a cell wall that protects and supports the plant cell. Has a large vacuole which is used to store materials & excrete them. Nucleus

Prokaryotic Cells Simple cells. Have NO membrane bound organelles No nucleus: DNA is free to float in the cytoplasm. Prokaryotes usually made of only ONE CELL. Have a cell membrane, cell wall, and an outer layer called a capsule. Also have cilia & flagella

Things to do today… Egg osmosis lab DAY 2 –I will call groups up two at a time. CBA Review –CBA is next class. It is PRETTY LONG. –We will go over the questions. Animal vs. Plant Cell Lab –START on it IF you have time. –We have until Friday to finish this lab.

Egg Osmosis Lab If you were absent last class get with a group! Make observations Remove egg CAREFULLY and rinse the egg. Weigh egg and observe amount of vinegar left in beaker. Rinse beaker Fill beaker with 200mL of syrup and replace egg. Turn in your data sheet. THE END.
