Week #1 -autotrophs are organisms that harvest light or chemical energy in organic compounds. They self nutrition -heterotrophs are organisms that get complex nutrients from the environment (by eating other organisms) -Fungi are heterotrophs or predators because they are parasitic. Bread mold secretes digestive enzymes to enter the membrane. Same as foot fungus‚ it extends hyphae (fungal branches) into the cells to absorbs nutrients -One fungus makes traps for nematode worms while another fungus

STUDY GUIDE INTEGRATED SCIENCE 10 PLANT UNIT DO YOU/CAN YOU…. 1. Understand that both plants and animals (eukaryotes) undergo a similar process for cellular division/reproduction? Both plant and animal cells undergo mitosis and meiosis. In plants‚ there is an alternation of generations; the gametophyte generation‚ where haploid gametes (pollen and ovule; sperm and egg) are produced via mitosis. Then the sporophyte generation combines these two into spores via meiosis‚ resulting in a diploid

goal of science is to provide explanations for events in the natural world and to understand patterns in nature to make useful predictions about natural events. Scientific methodology involves observing and asking questions‚ making inferences and forming hypotheses‚ conducting experiments‚ collecting and analyzing data‚ and drawing conclusions. Key Terms 1. Science- organized way of gathering and analyzing evidence about the natural world 2. Observation- the act of noticing and describing events
