egrep (which is the same as grep -E) treats +, ?, |, (, and ) as meta-characters. In basic regular expressions (with grep), the meta-characters ?, +, {, |, (, and ) lose their special meaning. If you want grep to treat these characters as meta-characters, escape them \?, \+, \{, \|, \(, and \).
Plants, fungi, and some protists also perform meiosis. In plants, meiosis creates a multicellular haploid organism, called a gametophyte , which in some groups is independent of the diploid plant. Gametes are produced by mitosis of the gametophyte, which then fuse to form the embryo. This cycle is called alternation of generations. Meiosis involves two divisions.
Meiosis is a division process that produces four daughter cells each containing haploid number of chromosomes.onfidence votes 5.0K.
