Document Summary
Identify key similarities and differences between plants and animals at the cellular level. Identify key differences and differences between plants and animals at the organismal level. Compare and contrast how animals and plants obtain energy and building blocks. The cell is the fundamental unit of life. Intracellular organelles - nucleus, mitochondria, er, golgi (shared feature of eukaryotes) Plasma membrane - shared feature among all life domains. Chloroplasts - harvests energy from light, stores energy as atp, uses atp to fix co2 and store the energy as simple sugars. Cell wall - water crosses through osmosis, can withstand high osmotic pressure whereas animal cells cannot. Key difference between animals and plants at the organismal level. Body organization differs fundamentally between plants and animals. Must be able to cope with changes in the environment (more stressors) 4 main tissue types: epithelial, connective, muscle, nervous - organized into various organs.
