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.
(Compare the FINAL products, after mitosis & meiosis are entirely complete.)ï  A) Mitosis produces TWO daughter cells from one parent cell; meiosis produces FOUR daughter cells from one parent cell.ï  B) Mitosis produces HAPLOID daughter cells; meiosis produces DIPLOID daughter cells.ï  C) Mitosis has TWO cell divisions; meiosis has only ONE cell ...
