Whats are the differences between Prokayote and Eukaryote?
Prokaryote- no nucleus, no organelles, example bacteria
Eukaryote- nucleus, organelles, example anything else
What are the differences between Animal and plant cells?
Animal- no cell wall, no chloroplasts, centrioles, vesicles
Plant-cell, chloroplast, no centrioles, vacuoles
What is vacuole called in animal cells?
Vesicle.
Nucleus-
Control Center, holds DNA
Nucleolus-
Assembles ribosomes
Golgi bodies-
Modifies, sorts, and packages proteins from the ER
Lysosomes-
Filled with enzymes to digest organelles.
Smooth ER-
sends materials. Ribosomes not on surface.
Rough Er
Sends messages and materials. Ribosomes found on surface.
Ribosomes-
Found throughout cytoplasm
Chroloplasts-
Green, photosynthesis.
Cell membrane-
Made of proteins and lipids, regulates what goes in and out of the cell.
Cell wall-
Protection of the cell, provides support (dead)
Vacuole-
Saclike structures that stores materials.
Mitochondria-
Converts chemical energy in food into my convenient energy. (Powerhouse)
Cytoplasm-
Substance holding cell organelles in place
Centrioles-
Helps organize cell division (split)
