Definition, Mitosis, Meiosis & Vs Cancer Introduction Cells are the most basic units of life, and every living organism is made up of one or more cells. These cells reproduce by copying their genetic information and undergoing cell division, where the parent cell gives rise to two daughter ...

Sex chromosomes are particular chromosomes that are involved in determining the sex of an organism. In the cells of humans and many other organisms the sex chromosomes consist of a pair of chromosomes called the X and Y chromosomes. The X and Y chromosomes were first discovered in beetles by ...
How is cell division in prokaryotes different from eukaryotes? (a) What types of cells does meiosis make? (b) How about mitosis? Is the cell division involved in gamete formation not of the same type in different organisms? What type of cell division occurs during microspo...
Different types of lymphocytes involved in immune responses are: T-cells or T- lymphocytes: ''T'' stands for thymus, the organ in which these cells mature. T-cells are involved in cell mediated immunity. B-cells also called B-lymphocytes: Here, the ''B'' stands for bone marrow, and ...
Gametes are produced through the process of meiosis. Meiosis is a type of cell division in which chromosome number in daughter cells becomes half of the parent cells. During meiosis, recombination and crossing over of genes occur, bringing genetic variations in the gamete. During fertilization, the...
What types of cells use mitosis for division? What are the two types of cell division? What are some characteristics of the different types of cell division? Which cells do not undergo cell division? Meiosis occurs in which type of organisms? a. single-celled b. multicellular c. all Wh...
A new concept of cell totipotency is formulated, as expressed in plant cells when, by means of a meiotic-like process, they acquire a gametic condition. 展开 关键词: TOTIPOTENCY MITOSIS MEIOSIS CELL CYCLE SOMATIC EMBRYOGENESIS PLANT REGENERATION POLYPLOIDY SOMACLONAL VARIATION ...
Insexual reproduction, two parents donate genes to their offspring through a process called fertilization. The resulting young receives a combination ofinherited genes. In fertilization, male and femalesex cellsor gametes fuse to form a single cell called a zygote. A zygote grows and develops bymito...
Some examples of the organisms that reproduced asexually are bacteria, fungi, various plants, and some animals. Sexual Organisms: Organisms that Reproduce Sexually The mode of reproduction in which the fusion of reproductive cells/gametes is involved to produce offspring is known as sexual ...
