Cell division and growth occur through the cell cycle, which consists of interphase and the mitotic phase. During interphase, the cell grows and duplicates its DNA in preparation for division. Interphase includes G1, S, and G2 phases where the cell accumulates building blocks and energy for DNA replication in S phase. In mitosis, the duplicated DNA and cell contents are separated into two daughter cells through karyokinesis and cytokinesis. Cell division allows organisms to grow, develop, replace old cells, and produce new cells or organisms.

1. Chapter 4 Tissues and Histology • Tissues - collections of similar cells and the substances surrounding them • Tissue classification based on structure of cells, composition of noncellular extracellular matrix, and cell function • Major types of adult tissues – Epithelial – Connective – Muscle – Nervous • Histology: Microscopic Study of Tissues – Biopsy: removal of tissues for diagnostic purposes – Autopsy: examination of organs of a dead body to determine cause of death
human cell anatomy - "cell is a basic structural unit of life" -as all living organism are made up of cells knowing the unique functions of the cell, shape, anatomy , function of organelle, and types of human cell involved are the most important factors and to also understand about -how human cells can play a vital role in our daily life.
A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The nucleus is a structure inside the cell that contains the nucleolus and most of the cell's DNA. It is also where most RNA is made.
The cell is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.
The study of the cell cycle focuses on mechanisms that regulate the timing and frequency of DNA duplication and cell division. As a biological concept, the cell cycle is defined as the period between successive divisions of a cell. During this period, the contents of the cell must be accurately replicated.
The cell cycle is regulated by cyclins and cyclin-dependent kinases.
How long is one cell cycle?
Depends. Eg. Skin cells every 24 hours. Some bacteria every 2 hours. Some cells every 3 months. Cancer cells very short. Nerve cells never.
Programmed cell death:
Each cell type will only do so many cell cycles then die. (Apoptosis)

The ability of organisms to produce more of their own kind is the one characteristic that best distinguishes living things from nonliving matter. This unique capacity to procreate, like all biological functions, has a cellular basis. The continuity of life is based on the reproduction of cells, or cell division. Cell division plays several important roles which are giving rise to a new organism, enabling development, renewing and repairing and also replacing damaged tissue is multicellular organisms.
توانایی موجودات زنده در تولید بیشتر از نوع خود یکی از ویژگیهایی است که موجودات زنده را از مواد غیر زنده به بهترین وجه متمایز می کند. این ظرفیت منحصر به فرد برای تولید مثل، مانند همه عملکردهای بیولوژیک، دارای پایه سلولی است. تداوم زندگی براساس تولید مثل سلولها یا تقسیم سلولی است. تقسیم سلولی چندین نقش مهم را ایفا میکند که نه تنها باعث ایجاد یک ارگانیسم جدید میشود، همچنین امکان رشد، تجدید و ترمیم و همچنین جایگزینی بافت آسیب دیده موجودات چند سلولی را نیز فراهم می کند.
cell division - Mitosis in plants final.pptReddykumarAv
mitosis is used for almost all of your body’s cell division needs. It adds new cells during development and replaces old and worn-out cells throughout your life. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less.

Oliver Twist; or, the Parish Boy's Progress is Charles Dickens's second novel, and was first published as a serial from 1837 to 1839. The story centres on orphan Oliver Twist, born in a workhouse and sold into apprenticeship with an undertaker.
The conditions of Akbar's birth in Umarkot, Sindh, India on October 15, 1542, gave no indication that he would be a great leader. Though Akbar was a direct descendent of Ghengis Khan, and his grandfather Babur was the first emperor of the Mughal dynasty, his father, Humayun, had been driven from the throne by Sher Shah Suri. He was impoverished and in exile when Akbar was born.
Humayun managed to regain power in 1555, but ruled only a few months before he died, leaving Akbar to succeed him at just 14 years old. The kingdom Akbar inherited was little more than a collection of frail fiefs. Under the regency of Bairam Khan, however, Akbar achieved relative stability in the region. Most notably, Khan won control of northern India from the Afghans and successfully led the army against the Hindu king Hemu at the Second Battle of Panipat. In spite of this loyal service, when Akbar came of age in March of 1560, he dismissed Bairam Khan and took full control of the government.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Cell division
• All cells are produced by divisions of pre-
existing cell.
• Continuity of life depends on cell division
• Cell division is the process by which a
parent cell divides into two or more
daughter cells.
• Because of the cell division, organisms grow
and develop, replace old or damaged cells,
and produce new cells or organism.
3. Cell cycle
• The cell cycle or cell-division cycle is the series
of events that take place in a cell leading to its
division and duplication of its DNA (DNA
replication) to produce two daughter cell
• The cell cycle is an ordered series of events
involving cell growth and cell division that
produces two new daughter cells
4.
5. • The cell cycle is the period from the
beginning of one division to the
beginning of the next
• the cell cycle has two major phases:
interphase and the mitotic phase
• During interphase, the cell grows and DNA is
replicated.
• During the mitotic phase, the replicated DNA
and cytoplasmic contents are separated, and
the cell divides.
6. Interphase
• Interphase is the first stage of the cell cycle
• During interphase, cells grow, make copies of
their DNA, and prepare to divide into two new
cells
• Cell prepare itself so that it can be divided into
daughter cells
• It is divided into three phases
• G1
• S
• G2
7. G1
• The first stage of interphase is called the G1 phase (first
gap)
• Cell active biochemically
• it either occupies 30 to 50 per cent
• The cell is accumulating the building blocks of
chromosomal DNA
• associated proteins as well as accumulating sufficient
energy reserves to complete the task of replicating each
chromosome in the nucleus.
• since it involves synthesis of RNA, proteins i.e DNA
polymerase and membranes which leads to the growth of
nucleus and cytoplasm of each daughter cell
• ENZYMES
8. S Phase (Synthesis of DNA)
• Throughout interphase, nuclear DNA remains
in a semi-condensed chromatin configuration
• DNA gets doubled
• Centrosome divide give rise to centriole
• Start moving opposite pole
• each chromosome has two DNA molecules
and a duplicate set of genes
• 35 to 45 per cent of cell cycle
9. G 2
• Some cell organelles are duplicated
• Cells make copies of their mitochondria and
chloroplasts
• REMAING PROTEIN LIKE MICROTUBLES,
MITOSIS SPECIFIC PROTEINS
• At the end of Interphase, the cell is ready to
divide
10. M phase
• It is phase of division
• After the early preparatory period now cells
ready to divide and divide by many ways
• It is again of two types
• Mitosis
• Meiosis
• Amitosis (occur in lower organism only
without inter phase)
12. Amitosis
• Occur in those organism which lack nucleus
and membrane bound organelle.
• It is type of A sexual reproduction
• Cells divide directly without spindle formation
and without appearance of chromosome
• The polyploid macronucleus found
in Ciliates divides mitotically
• BINARY FISSION AND
