Practice test for Mitosis/Meiosis

The passing of traits from parents to their offspring

Heredity

Refers to individiual that possess characteristics different from any kind

Variation

The study of heredity and varitaion

Genetics

The process of reproduction of unicellular cells and an asecual means of reproduction

Binary Fission

The genetic materials of the cell in the form of long threads of DNA

Chromatic FIbers

A protein complex assembled on the centromeric region of DNA

Kinetochore

The basic physical and functional unit of heredity.

Genes

A molecule that contains the biological instructions that mske each species unique

Deoxyribonucleic Acid(DNA)

A double membrane layer that seperates the contents of the nucleus form the rest of the cell

Nuclear Membrane

A round body located inside the nucleus of a eukaryotic cell

Nucleolus

Form protein structure that divides yhe the genetic material in a cell

Spindle Fiber

Are paired organelles found in cytoplasm

Centrioles

A thread like structure made of DNA

Chromosome

Seperates the interior of the cell drom the outside environment

Plasma Membrane

Cells that are rectangular,have cell walls,chloroplasts and a large vacuole

Plant cell

A series of events that takes place in a cell as it grows and divides

Cell cycle

The three stages of interphase

G1 Phase S Phase,G2 phase

The cell grows,accumulate nutrients ,and replicates its genetic material

Interphase

The two main stages of cell cycle

Interphase and M phase

Where cells spent their remaining time on this stage

M phase/Cell division

The stage where the cell is still young and undergoes rapid growth its also the longest phase in most cells

G1 Phase

The stgad where DNA replication happens

S Phase

The stage where the preparation for cell division happen

G2 Phase

The stage where cell undergoes cell division

M phase

Hollow protein fiber that causes chromosomes to move during cell division

Microtubules

Division of nucleus is called?

Karyokinesis

Division of cytoplasm is called

Cytokinesis

Is a type of cell division in which nucleusof the cell divides into two nuclei with identical genetic material

Mitosis

The stage where nuclear membrane disappear and spindle fibers form

Prophase

The stage where chromosomes move and align themselves at the center

Metaphase

The stage where two sister chromatids divide and chromosomes move to opposite poles

Anaphase and Telophase

Cytokinesis starts at the middle of the cell and moves outward

Plate formation

Cytokinesis starts at exterior of the cell moving inward until the cell divides

Cleaveage Furrow Formation

The union of teo sex cells

Fertilization

How many chromosomes that haploid cell has?

23

How many sets of chromosomes that a zygote cell have?

2 sets

The 2 sets of chromosomes of a zygote

Diploid Cell(2n), 46 Chromosomes

Formation of the sperm cell occurs in the testis

Spermatogenesis

Development of egg cell

Oogenesis

It occurs in the body cells, its final chromosome number is diploid,2n( 46 Chromosomes in humans) and for growth, development,repair and maintenance of tissues, asexual reproduction

Mitosis

It occurs in Sex cells, its final chromosome number Haploid,n(23 Chromosomes for humans),and uts function is gamete production needed for sexual reproduction

Meiosis

The gamete or sex cell formation among all male animals

Spermatogenesis

The ___ contain both the _____ and the ____; housed inside a pouch called a _____

Testes,Sperm cell, Male hormone, Scrotum

The full process lf spermatogenesis takes about ____

10 weeks

The gamete or sex cell formation among females

Oogenesis

Embryonic development -

25 immature egg cells
