Blood cells

AIM: Why do cells look different?

Prokaryotic and Eukaryotic Cells Prokaryotic Cells: no nuclei Eukaryotic cells: Nuclei, cell mem- Branes, organelles Organelles: specialized structures that perform cellular functions

If you were to design a cookie factory, what important features would be necessary? Custodians- lysosomes- enzyme-filled organelles that break down waste Raw materials- ribosomes- produce proteins Manager- nucleus- controls cell processes, contains genetic material Assembly Lines- cytoplasm Cookie machines- Endoplasmic Reticulum- assemble cell structures Packaging Center- Golgi Apparatus- modify proteins, and send off to destinations Storage- Vacuole- storage center for water and nutrients Form of energy- mitochondria- uses energy from food to power cell processes

How do plant cells differ from animal cells? 1)Plant cell has a cell wall- structure 2)Plant cell have chloroplasts- green color, photosynthesis 3)Plant cells- large central vacuole

How are structure and function related in cells?

Levels of Organization Cells Tissue- group of similar cells performing the same function Organs- many different tissues work together Organ System -Organs work together To complete life function

Quarterly labs 1-8 and all of the following topics: Scientific Method, Characteristics of Life, Ecology, Human Impact.
