What characteristics are shared by most cells? 3. How did improvements in the microscope help scientists form the cell theory? 4. How do prokaryotic and eukaryotic cells differ? 5. Today‚ scientists can study human cell grown in petri dishes. Explain how this technique builds on the work of early

assembles Ribosomes. * Endoplasmic Reticulum Smooth- does the synthesis of lipids. * Endoplasmic Reticulum Rough- is responsible for protein manufacturing. * Vacuoles- accumulates excess water and pumps it out to pores. * Golgi Apparatus- sorts‚ packages and transports substances. * Vesicles- * Lysosomes- responsible for digestion of waste materials. * Mitochondria- responsible for the production of ATP (energy). * Chloroplast- responsible for photosynthesis.

the endoplasmic reticulum is the highways. The protein vesicles are the trucks on the highways and the lysosome is the trash collector. Now the eukaryotic cell has two types and they are plant and animal cells. Plant cells have a wall around the plasma cell membrane and animal cells just have the membrane. The plant cell as one big vacuole and the animal had a few small ones. The vacuoles stores molecules that the cell needs and quarantines harmful materials. All of these works together to

PATTERNS IN NATURE – Summary Notes 1. ORGANISMS ARE MADE OF CELLS THAT HAVE SIMILAR STRUCTURAL CHARACTERISTICS 1.1 Outline the historical development of the cell theory‚ in particular‚ the contributions of Robert Hooke and Robert Brown The Cell Theory states that: All living things are made of cells (Theodor Schwann & Matthias Schleiden) Cells are the basic structural and functional unit of organisms (Theodor Schwann) All cells come from pre-existing cells (Rudolf Virchow) The historical

ability to survive within a host cell. L. pneumophila protects against lysis by using its effector proteins to obstruct the fusion of the Legionella-containing vacuole (LVC) with the hosts’ endosomes. The Dot/Icm system is essential for induction of apoptosis in human macrophages. Another role of this system is to inhibit phago-lysosome fusion through the exportation of virulence factors. Research shows that macrophages that have been treated with an iron chelator do not support the replication

cause an allergic reaction‚ for example hives. The basophil white blood cell has all of the same organelles as a regular animal cell. It contains a nucleus‚ cytoplasm‚ cell membrane‚ nuclear membrane‚ Golgi body‚ E.R.‚ rough E.R.‚ ribosomes‚ lysosomes‚ vacuole‚ mitochondria‚ and cell wall. This cell has rough looking particles in its cytoplasm called granules‚ which you can only see under a microscope. This cell also contains histamine which will be released if the cell is exposed to any allergic

What it does in the cell (functions) It maintains the integrity of the genes and controls the activities of the cell. Something that performs the same function in the “real world” It works like a CPU sending out messages.
