involved in the synthesis of lipids

Question 7

Nucleus

Answer 7

holds chromosomal info

Question 8

Golgi apparatus

Answer 8

transports, modifies and packages proteins and lipids, also membrane bound

Question 9

Answer 9

microfilaments, intermediate filaments, thick filaments and microtubules extending through the cytoplasm in cells

Question 10

Microvilli

Answer 10

increase surface are in order for better absorption. uptake and secretion of molecules

Question 11

cilia

Answer 11

hair-like filaments that facilitate movement, especially of fluid, by a vibrating motion

Question 12

Diffusion

Answer 12

concentration high -> low

Question 13

osmosis

Answer 13

movement of solvents across and semi-permeable membrane

Question 14

Active transport

Answer 14

movement from low concentration -> hight concentration

Question 15

Endocytosis

Answer 15

uptake to molecules by merging with cell membrane

Question 16

Exocytosis

Answer 16

vacuoles filled with molecules merge with cell membrane to expel things

Question 17

Phagocytosis

Answer 17

uptake and digestion of bacteria and other molecules by phagocytes. they ingest them basically. ie: macrophages (white blood cells)
