SPECIALISED ANIMAL CELLS

• Dendrites – They are hair like structures that receives the impulses
• Axon – Long stalk the transmits the nerve impulses
• Synapse – They transmit impulses from one neurone to another

MUSCLE CELL

• Functions is to contract to bring about the movement of different parts of the body
• They are made up of special fibres which helps them to contract and relax
• Contain special proteins that allows them to contract and relax
• They have loads of mitochondria which provides them energy to contract
• They can store special storage carbohydrate called glycogen which acts as fuel for the muscles

• Flagella – Helps it to swim to large distances
• Mitochondria – Provides Energy to swim
• Nucleus – Contains genetic information
• Acrosome – Contains Hydrolytic enzyme to break the egg wall and penetrate inside the egg to fuse with the egg nucleus

MICROSCOPES

Magnification.

Light and Electron Microscopes

Movement of substance in and out of the cells, active transport.

• Movement of particles from a region of low concentration to a region of high concentration.
• Particles move against the concentration gradient.
• It requires energy.
• Cells involved in active transport should have lots of mitochondria

PASSIVE TRANSPORT

• Movement of particles from the region of high concentration to a low concentration.
• Particles move along the concentration gradient.
• It does not require energy
• Having numerous mitochondria is not a requirement
• It the net movement of particles from an area of higher concentration to an area of lower concentration.
• It is passive process
• It happens along the concentration gradient
• No use of energy.

FACTORS AFFECTING DIFFUSION

Surface area.

• Greater the surface area greater is the rate of diffusion as particle will get more room for movement.
• All the exchange surfaces have greater surface area like root cells has root hairs and intestine cells has villi.

CONCENTRATION GRADIENT

• Greater the difference in concentration in the two region greater is the rate of diffusion.
• All the exchange surfaces maintain steepest concentration gradient
• Like root cells are closed to xylem and Villi has rich blood supply.

DIFFUSION DISTANCE

• Smaller the diffusion distance greater is the rate of diffusion as the particles have to travel a smaller distance.
• All the exchange surfaces maintain a smaller diffusion distance by being one cell thick.

TEMPERATURE

• Greater the temperature greater is the rate of diffusion as particles will get more kinetic energy for movement
• Rate of Diffusion = Surface area x Concentration gradient/Diffusion Distance

OSMOSIS – Special Case of Diffusion

• It is the diffusion of only water molecules
• It required a semi permeable or partially membrane
• Membrane that allows only specific molecules to pass through like water.

OSMOSIS IN PLANTS

• Hypertonic – The outer solution has a less concentration of water than inside the cell.
• Isotonic – The outer solution has same concentration of water than inside the cell.
• Hypotonic – The outer solution has a greater concentration of water than inside the cell.

Osmosis in Animals

• Movement of substances from the region of low concentration to a region of higher concentration with the use of energy.
• Dependent on respiration as it requires energy. So the cells involved in active transport has lots of mitochondria.
• In Plants water and minerals are absorbed by active transport to absorb maximum of water and minerals.
• In animals, the digested food gets absorbed into the blood by active transport to ensure maximum absorption
• Salt glands are present in some marine organisms which removes the salt by active transport.

Interphase –

• It is the longest phase of the cell cycle
• The cell grows in size and prepares all the proteins and enzymes needed for division.
• Replication of DNA where DNA duplicates its content.
• It is the division of the nucleus in which parent cell splits into two daughter nuclei containing same number of chromsomes as the parent cell.

Cytokinesis

• It is the division of the cytoplasm which .takes place after the division of the nucleus.
• It is the type of cell division in which a parent nucleus divides to form two daughter nuclei with exactly the same number of chromomes as that of the parent nucleus.
• The daughter cells produced are genetically identical to the parent and are clones.
• This division is important for growth, regneration and repair.
• Mitosis is also important in asexual reproduction.

CELL DIFFERENTIATION

• It is the process by which cell becomes specialised to perform a specific function.
• Male Parent (23 pairs of chromosomes)                            Meiosis
• Female Parent (23 pairs of chromosomes) Meiosis

Animal Differentiation

• In animals majority of the cells are differentiated at an early stage and different cells have specific functions like nerve cell, muscle cells.
• Adult stem cells replaced the old and worn out cells in human but adult stem cells have limited specialization power
• Majority of the differentiation is permanent

Plant Differentiation

• Plants are the storehouse of stem cells
• Root meristems and shoot meristems are the parts of actively growing part of the cells which contains stem cells.
• The plants can be cloned easily as it has many undifferentiate cells and differentiation is not permanent.
• Undifferentiate mass of cells that can differentiate into any cell type are known as stem cells.
• Sources of Stem Cells : Embryo, left over remains of the embryo and the umbilical chord are the sources of embryonic stem cells.
• Bone marrow is the source of adult stem cells.
• Can solve the rejection problem if the transplanted organ is made from the person’s own stem cells.
• Can be possible cure of neuro-degenerative diseases
• Can be the potential cure of diabetes.
• Therapeutic cloning.
• Organ damage problem

ISSUES AGAINST STEM CELLS

• It can lead to cancer as the stem cells are rapidly dividing.
• The stem cells can be contaminated and can cause unwanted diseases to the patient.
• Research is still slow and expensive
• Research happens on aborted embryos which is considered as a potential source of life and many religions have ethical concerns against it.
• The knowledge of the genes switched on and off using differentiation is still incomplete.

KEY TERMS!!!

• Resolution – Ability to distinguish between closely placed objects.
• Magnification — Ability to enlarge an object
• Xylem – Transport tissue in plants that transports water and minerals.
• Phloem – Transport tissue in plants that transports food
• Diffusion – Movement of substance from a higher concentration to a lower concentration.

• Plasmolysis— Shrinking of plant cell when placed in hypertonic solution.
• Turgid — Fully swollen cell which has gained water by osmosis.
• Flaccid— soft cell due to no net movement of water.
• Mitosis — Cell division that produces identical daughter cells.
• Differentiation – Cell specialization
• Stem Cells – Undifferentiated mass of cells that can specialize to any cell type
