Lesson 1.6 Flashcards
An important biological principal formulated by him, he states that all cells come from other cells.
Rudolf Virchow
Process of cellular reproduction.
Cell division
The series of stages in the life of a cell.
Cell cycle
The longest space in the cell cycle for most cells, also known as preparatory stage.
Interphase
The actual cell division
Mitosis
Division of the cytoplasm
Cytokinesis
The first subphase
G1
What is the meaning of G in G1
Gap
Second subphase
S
Characterize mainly by DNA synthesis or application.
S (synthetic phase)
The identical copies of each chromosome that result from the replication.
Sister chromatids
These sister chromatids remain attached to each other at a point.
Centromere
Derived from the latin word mito means?
Threads
Described as dynamic continum
Mitosis
Equal nuclear division
Karyokinesis
Division of the cell body
Cytokinesis
The process of mitosis is designed as?
Somatic Cell Division
Mitosis divided into a serious of phase
Prophase
Metaphase
Anaphase
Telophase
The combination of mitosis and cytokinesis
M phase (mitotic phase)
Formation of mitotic Spindle.
Significant changes in both the nucleus and cytophlasm occurs.
Prophase
Opposite sides of the cell
Spindle poles
Highly condensed chromosomes and attach to the protein structure
Kinetochore
Alighnment of chromosomes.
As the cells enters into metaphase, the chromatids begun moving toward the center of the cell and align midway between the spindle poles, or along the spindle equator.
Metaphase
Movement of the Daughter Chromosomes
Anaphase
Each chromatid is now considered a full-fledged chromosomes
Daughter chromosome
Formation of two Daughter Nuclei.
It begins as soon as the daughter chromosomes reach the opposite end of the poles
Telophase
Division of the cytoplasm
Cytokinesis
In plant cells, cellulose deposits accumulate along the equator, forming a structure
Cell plate
The cytoplasm divides by the formation of a groove
Cleavage furrow
Kinds of interphase
G1, S, G2
Kind of mitosis
Prophase
Metaphase
Anaphase
Telophase
Phase of the cell
Interphase
Prophase
Metaphase and Anaphase andTelophase and Cytokinesis
Growing out of control
Cancer cells
The sequential events Of the cell cycle are direct, consist of specialized proteins within the self.
Cell cycle contra system
Abnormally growing mass of body cells
Tumor
If the abnormal cells remain at the original site, the lump called?
Benign tumor
Can spread into neighboring tissue and other parts of the body
Malignant tumor
The spread of cancer cells be on their original site
Metastasis
Three main types of cancer treatment
Slash
Burn
Poison
Surgery to remove a tumor
Slash
Radiation therapy
Burn
Chemotherapy
Poison
Each of the 23 pairs
Homologous
Cell that contains two complete sets of homologous pairs of chromosomes
Diploid number (2n)
A cell containing a single set chromosomes
Haploid cell
Haploid sperm cell
Man
Haploid egg cell
Female
Sexual reproduction, haploid sperm cell from the father fuses with a haploid Egg cell from the mother
Fertilization
It is the results in a fertilized egg, which is deploid
Zygote
Haploid gametes are produced by a serial types of cell division
Meiosis
Each chromosomes consist of two strands of sister chromatids connected at the centromere
Meiosis I
Chromosomes become think visible
Prophase I
The homologous us chromosomes are still together
Metaphase I
The homologous pairs of chromosomes separate from each other
Anaphase I
A new nuclear envelope may or may not formed during in this
Telaphase I
Each chromosome replicated to become two sister chromatids
Meiosis II
The chromosomes of all organisms contain regions
Genes
Is the exchange of the genes between pirs of homologous chromosomes.
Crossing over
Is the process by which commits a reproductive cells are formed by meotic division
Gametogenesis
Two types of gametogenesis
Spermatogenesis
Oogenesis
Sperm cell formation
Spermatogenesis
Ovum/ egg cell formation
Oogenesis
The cells whuch constitute the body or?
Soma
Mitosis is described as?
Dynamic continuum
