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.
Haploid cells are gametes, meaning they are reproductive cells. They have half the number of chromosomes as somatic cells. Diploid (somatic) cells are in every part of t â¦ he body other than the gametes. The have twice the amount of chromosomes as in haploid cells. Haploid cells reproduce using meiosis, while diploid cells use mitosis. a haploid cell has half the amount of chromosomes of a diploid cell. human germ cells are haploids (the egg and sperm) they each contain 23 chromosomes. 18 people found this useful.
