The document discusses the cell cycle and cell division processes of mitosis and meiosis. It defines the main phases of each process and compares the key differences between mitosis and meiosis. Mitosis involves one cell division producing two identical daughter cells, while meiosis involves two cell divisions producing four non-identical haploid daughter cells. The stages of each process including interphase, prophase, metaphase, anaphase and telophase are outlined in detail. Diagrams and animations are provided to illustrate each phase.

– Male and female gametes fuse together during fertilization to form a zygote. The chromosome number is halved during the formation of gametes by the process of meiosis. This maintains the chromosome number generations after generations. Meiosis leads to genetic diversity which is very essential for evolution.
Most relevant information about the cell, its discovery, types and various kinds of organelles and their function. it also focus on how molecules are transported across the cell membrane.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
7. Mitosis
The process of cell division which results
in the production of two daughter cells
from a single parent cell.
The daughter cells are identical to
one another and to the original parent
cell.
8. Mitosis can be divided into stages
• Interphase
• Prophase
• Metaphase
• Anaphase
• Telophase & Cytokinesis
9. Interphase
The cell prepares for division
• Animal Cell
– DNA replicated
– Organelles replicated
– Cell increases in size
• Plant Cell
– DNA replicated
– Organelles replicated
– Cell increases in size
13. Metaphase
The cell prepares chromosomes for
division
• Animal Cell
– Chromosomes line up
at the center of the cell
– Spindle fibers attach
from daughter cells to
chromosomes at the
centromere
• Plant Cell
– Chromosomes line up
at the center of the cell
– Spindle fibers attach
from daughter cells to
chromosomes at the
centromere
15. Anaphase
The chromosomes divide
• Animal Cell
– Spindle fibers pull
chromosomes apart
– ½ of each
chromosome (called
chromotid) moves to
each daughter cell
• Plant Cell
– Spindle fibers pull
chromosomes apart
– ½ of each
chromosome (called
chromotid) moves to
each daughter cell
17. Telophase
The cytoplasm divides
• Animal Cell
– DNA spreads out
– 2 nuclei form
– Cell wall pinches in to
form the 2 new
daughter cells
• Plant Cell
– DNA spreads out
– 2 nuclei form
– New cell wall forms
between to nuclei to
form the 2 new
daughter cells
23. Meiosis
Meiosis is the type of cell division by which
germ cells (eggs and sperm) are produced.
One parent cell produces four daughter
cells.
Daughter cells have half the number of
chromosomes found in the original
parent cell
27. First Division of Meiosis
• Prophase 1: Each chromosome duplicates and
remains closely associated. These are called sister
chromatids.
• Metaphase 1: Chromosomes align at the center of the
cell.
• Anaphase 1: Chromosome pairs separate with sister
chromatids remaining together.
• Telophase 1: Two daughter cells are formed with
each daughter containing only one chromosome of the
chromosome pair.
33. Second Division of Meiosis
• Prophase 2: DNA does not replicate.
• Metaphase 2: Chromosomes line up at the center of
the cell
• Anaphase 2: Centromeres divide and sister
chromatids move separately to each pole.
• Telophase 2: Cell division is complete.
Four haploid daughter cells are formed.
39. Differences in Mitosis & Meiosis
• Mitosis
– Asexual
– Cell divides once
– Two daughter cells
– Genetic information is
identical
• Meiosis
– Sexual
– Cell divides twice
– Four haploid daughter
cells
– Genetic information is
different
