2. Animal cells and their shapes
Cells are the building blocks of life – all living
organisms are made up of them. Textbooks
often show a single ‘typical’ example of a plant
cell or an animal cell, but in reality, the shapes
of cells can vary widely. Animal cells in particular
come in all kinds of shapes and sizes. Plant cell
shapes tend to be quite similar to each other
because of their rigid cell wall.

4. Types of Cells
•
Cell Type
Both plant and animal cells are eukaryotic in nature, having a well-defined
membrane-bound nucleus.
Nucleus
It is present in both. The nucleus carries most of the genetic material in
the chromosomes, which carry the genetic information in the form of DNA
(deoxyribonucleic acid).
Cell Membrane
It is a semi-permeable or selectively-permeable membrane that encloses
the contents of a cell, allowing only selected molecules to enter the cell
and blocking the others.
Mitochondria
They act as the powerhouse of the cell, converting food into energy.

5. Cell Division
• Cell division is the process by which a parent cell divides into
two or more daughter cells.[1] Cell division usually occurs as
part of a larger cell cycle. In eukaryotes, there are two distinct
type of cell division: a vegetative division, whereby each
daughter cell is genetically identical to the parent cell
(mitosis),[2] and a reductive cell division, whereby the number
of chromosomes in the daughter cells is reduced by half, to
produce haploid gametes (meiosis). Both of these cell division
cycles are required in sexually reproducing organisms at some
point in their life cycle, and both are believed to be present in
the last eukaryotic common ancestor[3] Prokaryotes also
undergo a vegetative cell division known as binary fission,
where their genetic material is segregated equally into two
daughter cells. All cell divisions, regardless of organism, are

6. Plant Cell
• Plant cell structure
• Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their
distinctive features include:
• A large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast[1][2] that maintains
the cell's turgor, controls movement of molecules between the cytosol and sap, stores useful material and digests
waste proteins and organelles.
• A cell wall composed of cellulose and hemicellulose, pectin and in many cases lignin, is secreted by the protoplast
on the outside of the cell membrane. This contrasts with the cell walls of fungi (which are made of chitin), and of
bacteria, which are made of peptidoglycan.
• Specialized cell-to-cell communication pathways known as plasmodesmata,[3] pores in the primary cell wall
through which the plasmalemma and endoplasmic reticulum[4] of adjacent cells are continuous.
• Plastids, the most notable being the chloroplast, which contains chlorophyll, a green-colored pigment that absorbs
sunlight, and allows the plant to make its own food in the process known as photosynthesis. Other types of
plastids are the amyloplasts, specialized for starch storage, elaioplasts specialized for fat storage, and
chromoplasts specialized for synthesis and storage of pigments. As in mitochondria, which have a genome
encoding 37 genes,[5] plastids have their own genomes of about 100–120 unique genes[6] and, it is presumed,
arose as prokaryotic endosymbionts living in the cells of an early eukaryotic ancestor of the land plants and
algae.[7]
• Cell division by construction of a phragmoplast as a template for building a cell plate late in cytokinesis is
characteristic of land plants and a few groups of algae, notably the Charophytes[8] and the Order Trentepohliales[9]
• The sperm of bryophytes and pteridophytes, Cycads and Ginkgo have flagella[10] similar to those in animals,[11][12]
but higher plants, (including Gymnosperms and flowering plants) lack the flagellae and centrioles[13] that are
present in animal cells.

7. Animal Cell
• An animal cell is a form of eukaryotic cell that
makes up many tissues in animals. The animal
cell is distinct from other eukaryotes, most
notably plant cells, as they lack cell walls and
chloroplasts. They also have smaller vacuoles.
Due to the lack of a cell wall, animal cells can
adopt a variety of shapes. A phagocytic cell
can even engulf other structures
