Cerebrum is the seat of conscious- ness, intelligence, memory, imagina- tion and reasoning. It receives impulses from different parts of the body and initi- ates voluntary activities. Specific areas of cerebrum are associated with spe- cific functions. Thus there is a centre for hearing, another for seeing, another for tasting, another for smelling, another for speaking and so on. A damage in a specific centre of cerebrum will de- prive the particular faculty from doing its Fig 3.

Sensory areas: Cerebrum wraps around a structure These are the sites where the sensory called thalamus — a major conducting functions of the various sense organs are centre for sensory and motor signalling.

Association areas: It lies at the base of the thalamus. It These are responsible for complex controls body temperature, urge to eat and functions like intersensory associations, drink, regulation of sexual behaviour, ex- memory and communication. White matter of cerebrum: The inner part of the cerebrum ly- ing below the cerebral cortex is called white matter and it consists of bundles of nerve fibres with myelin sheath giv- ing the white colour.

Some of these bun- dles of nerve fibres connect the different parts of the cerebrum while others con- nect the cerebrum with the rest of the brain and spinal cord. Within the cerebral hemispheres are present cavities called ventricles, filled with a nutritive fluid called cerebro spinal Fig 3.

The chemical coordination of physiological processes to maintain the homeostasis is the work of endocrine system. Endocrines control and coordinate the physical proc- esses of growth, reproduction and suste- nance of life.

Endocrine system consists of a number of endocrine glands and their hormones. Endocrine glands are ductless glands without ducts , secreting the chemical substances called hormones. The hor- mones are carried by the blood from the site of production to the site of action. Fig 3. The various en- docrine glands found in different regions Chemically hormones are proteins or in man are as follows: Though the hor-.

Pituitary gland: It is a tiny gland of the size of a pea at- tached to the hypothalamus of the brain. Since some of the endocrine glands are regulated by the pituitary gland, it is called as the conductor of endocrine orchestra. Divisions or lobes of pituitary gland Pituitary gland is differentiated into an anterior lobe called adenohypophysis and a posterior lobe called neurohypo- physis. Adenohypophysis It secretes a number of hormones.

The important hormones and their functions and malfunctions are as follows: Chapter 3 Follicle stimulating hor- It stimulates the maturation of graafian follicles in mone FSH the ovary in the female, to produce the eggs and sperm formation in the males.

Hormones of Neuro Functions and malfunctions hypophysis Oxytocin It speeds up the child birth process, by stimulating the contraction and relaxation of the uterus in the female.

Vasopressin It helps in the reabsorption of water, producing concen- or antidiuretic hor- trated urine in small quantity. Thyroid gland: Functions of thyroxine: Thyroxine is an iodinated of tissues. Thyroid gland bulges as a swelling in the neck and it is called as goiter. The symptoms are high metabolic rate, high blood pressure, high irritability, profuse sweating, loss of weight, fatigueness and protrusion of eyeballs. Thyroid disorders: The islets of Langerhans:.

Do you know that all living organisms re- produce both plants and animals? Re- production is a special biological process, by which new individuals of the same spe- cies are produced. It is one of the bio- logical processes like nutrition, respiration and excretion etc. What will happen if there is no repro- duction? Fig 4. Let us examine how different organisms actually reproduce. The methods by which organisms reproduce depend upon the body shape and structure of organ- isms.

As you have already studied in your The main parts of a flower are, earlier classes, the flower is a the 1 Calyx reproductive organ of a flowering plant.

To understand this we need to look first 2 Corolla at the structure of a flower. A flower is a modified shoot with a limited growth.

Flowers vary in size, shape,structure and colour. Androecium is the male part of a 4. Androecium is a group of stamens. How does sexual reproduction take place Each Stamen consists of a stalk called in flowering plants? The pollen plants involves grains are contained in the anther within 1. Pollination the pollen sacs. Fertilization Gynoecium: Gynoecium is the female part of the flower and consists of the carpels or ovary. Gy- Transfer of pollen grains from the anther to the stigma is called pollination.

Pollen noceium has three parts 1 Stigma 2 Style grains are transferred mainly by wind, wa- and 3 Ovary. They are called as pol- The ovary contains the ovules and linating agents. Pollination is followed by fertilization. Types of Pollination: Pollination is of two types.

They are 1. Self pollination 2. Cross pollination. Self Pollination: Self pollination is also known as autogamy. How is it possible for the transfer of pollen The transfer of pollen grains from the an- grains from one flower to another? This takes place through agency Advantages of self pollination: Self pollination is certain in Pollination by birds Ornithophily bisexual flowers.

Flowers need not depend on Zoophily agents of pollination. There is no wastage of pollen grains. Observe the flowers in a garden near to you. Identify the insects, and birds,that act as pollinating agents. Disadvantages of self pollination: Maintain a record detailing the polli- 1. The seeds are less in number. Endosperm is minute. Therefore, linate the seeds produce weak plants.

New varieties of plants cannot be produced resulting in the Zoophily: Animals and insects — Birds, squirrels and insects are attracted to the bright petals of 4.

These flowers are also large in size and have a sweet smell. Some of The transfer of pollen grains of a flower to these flowers have nectar and a sweet the stigma of another flower of a different scent.

This is the most common of all plant of the same species is called cross methods of pollination. This kind of pol- pollination or allogamy. Pollination by animals and birds. Advantages of cross pollination: The seeds produced as a result of cross pollination develop, germinate properly and grow into better plants, i. More viable seeds are produced. Anemophily Pollination by wind: The flowers pollinated by air are mostly small in size and without any attractive colour, smell and nectar.

They produce a large number of pollen grains to make up for the wastage of pollen in times of transit. Recall what you have studied about pol- lination.

Each pollen grain has protective walls called ex- Some pollen grains even have wings. The outer wall exine is thick Some pollen grains even have wings. The inner wall is thin and elastic. Flowers pollinated by wind are called Germination of pollen grain: Anemophilous, e.

Grass and pine. If pollen grain falls on a suitable stigma, it starts germinating. The vegetative cell starts growing and anemophilous,hydrophilous flowers. The generative of their adaptations to suit the cell gets into the tube and divides into two corresponding pollination.

The flowers are small and Tube nucleus inconspicuous. Process of fertilization: Endosperm is a nutritive tissue meant for the development of the embryo. The The pollen tube enters into the em- process of fusion of a male gamete with bryo sac through micropyle.

Seeds have great variations in the size, shape, colour and surface. In orchids, there are many seeds which are tiny dust like particles. In coconut, there is a large sized seed. The seed grows into a full plant. On the basis of the number of cotyle- dons in the embryo seed , the angiosperms Polyalthia have been divided into two groups.

Berry Epicarp is thin and the mesocarp is fleshy. They form a pulp which is edible and the seeds are em- bedded in it. The epicarp is thick, leath- ery and contain oil glands.

The whitish spongy layer lining the epicarp is called mesocarp. The endocarp forms distinct cham- bers. Juicy hairs produced from the endocarp is the edible part.

The thalamus becomes fleshy and develops into a fruit which is edible. The true fruit containing seeds remain inside. The pulp contains many seeds. The pericarp is differentiated into outer skinny epicarp,fleshy middle mesocarp and stony inner endocarp. Be- cause of the presence of stony endocarp, the fruit is also known as stone fruit.
