Question 1:
Find the meaning of the words
Asexual reproduction
Reproduction in which there is no fusion of gamete and in which the genetic make up of parent and of offspring is usually identical.
Binary fission
Equal division of a cell or organism into two
Cell plate
The structure that form during cytokinesis in plats that separating two daughter cell in mitosis.
Chromatid
One of the 2 identical halve of the duplicated chromosomes.
Chromosome
structure in the cell nucleus that consist of chromatin and genes.
Cleavage furrow
A constricted region of the cytoplasm that form progressively depends during cytokinesis of the animal cell, thereby separating two daughter cell.
Cytogenesis
| The formation, development, and variation of cells. Also called cytogeny. |
Cytogenetics
The branch of biology that deals with heredity and the cellular components, particularly chromosomes, associated with heredity
Cytokinesis
Signaling protein that regulate interaction between cell in the immune systems.
Eukaryotes
An organism who cell have nuclei and other membrane-bounded organelles. Include protist, fungi, plants and animal.
Germ cell
The eggs and sperm are the germ cells: the reproductive cells. Each mature germ cell is haploid in that it has a single set of 23 chromosomes containing half the usual amount of DNA and half the usual number of genes.
Heterogamous
Characterized by the fusion of unlike gametes in the reproductive process and by reproduction involving the alternation of sexual and parthenogenetic generations
Homologous chromosome
Chromosomes that are similar in morphology and genetics constitution.
Isogamous
Describe a species that makes morphological similar gametes.
Karyotype
The chromosomal composition of and individual
Kinetochore
The portion of the chromosome centromere to to which the mitotic fibers attach.
Loci
The physical location of a gene within chromosome.
Metaphase plate
The plate at which chromosomes align during metaphase.
Microtubules
Hollow cylindrical fiber consisting of tubulin protein subunits.
Mitosis
The division of the cell nucleus resulting in two daughter nuclei each with the same number of the chromosome as the parent nucleus.
Nucleus
A membrane bounded organelle in eukaryotic cell where the linear set of chromosomes are found
Prokaryotes
A cell that lacks a nucleus and other membrane-enclosed organelles.
Restriction point
A point in the G1 phase og the cell cycle that cause a cell to progress to cell division.
Septum
The eggs and sperm are the germ cells: the reproductive cells. Each mature germ cell is haploid in that it has a single set of 23 chromosomes containing half the usual amount of DNA and half the usual number of genes.
Sister chromatid
Pairs of replicated chromosomes that are attached to each other at the centromere. Sister chromatid are genetically identical to each other.
Somatic cell
Refer to any cell of the body except for germ-line that give rise to gametes.
