A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of cytoskeletal structures [goid 7010] [evidence ISS]; The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell [goid 7165] [pmid 8969170] [evidence TAS]; The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult) [goid 7275] [pmid 8969170] [evidence TAS]; Any process that modulates the surface configuration of a cell [goid 8360] [evidence ISS]; Morphogenesis of an organ. An organ is defined as a tissue or set of tissues that work together to perform a specific function or functions. Morphogenesis is the process by which anatomical structures are generated and organized. Organs are commonly observed as visibly distinct structures, but may also exist as loosely associated clusters of cells that work together to perform a specific function or functions [goid 9887] [pmid 7954831] [evidence TAS]; A process that is carried out at the cellular level which results in the formation, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins [goid 30036] [pmid 8969170] [evidence IDA]; Any process that modulates the frequency, rate or extent of Rho protein signal transduction [goid 35023] [evidence IEA]; Any process that modulates the activity of the GTPase Cdc42 [goid 43088] [pmid 8969170] [evidence IDA]; The assembly of a filopodium, a very long microspike extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or by the growth cone of a developing nerve cell axon [goid 46847] [pmid 8969170] [evidence IDA]
