Photosynthesis takes placeinsideplantcells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to makephotosynthesis happen.

Plant photosynthesis occursin leaves and green stems within specialized cellstructurescalled chloroplasts. Oneplant leaf iscomposed of tens of thousands of cells, and each cell contains 40 to 50 chloroplasts.

The hypothalamus is responsible for the regulation of certain metabolic processes and other activities of the autonomic nervous system. It synthesizes and secretes certain neurohormones, called releasing hormones or hypothalamic hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones. The hypothalamus controls body temperature, hunger, important aspects of parenting and attachment behaviours, thirst,[2] fatigue, sleep, and circadian rhythms.

thelamus-The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The main function of the thalamus is to relay motor and sensory signals to the cerebral cortex.

spinal cord-The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone where it passes through the foramen magnum, and meets and enters the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. Also, the spinal cord has a varying width, ranging from 13 mm (1⁄2 in) thick in the cervical and lumbar regions to 6.4 mm (1⁄4 in) thick in the thoracic area.

The Carpel is a female part of a flower.

1.When the pollen grain gets onto the Stigma they germinate to send pollen tubes in the embryo sac of each ovule and get the ovule fertilized.

2. The carpel is then converted into a fruit and the ovules become seeds.

And I would like to add an introduction about the carpel. it may helpful if you want to know about it .

The Carpel

Acarpelis the innermost part of a flower. It is usually surrounded by male reproductive structures calledstamens, both of which are surrounded bypetals. The petals of flowers are often large and brightly colored. Before the flower opens, the petals are protected bysepals, which are usually green.

according to me answer will be C

radical will grow into the roots in future

cotyledons protect the plant and provide food

plumule will grow into the stem in future

Ovary - To produce the egg (ovum). To produce the hormones oestrogen and progesterone.

oviduct (fallopian tube): It is the site of fertilization. It carry egg (ovum) or fertilized ovum (zygote) to the uterus.

Uterus - It is the site of development of embryo. It is made up of muscle tissue. It protects and nourishes the embryo.Embryo nourished inside mother by placenta. Placenta is a vital organ formed by chorionic villi and uterine lining. This is the connection between the mother and embryo. This is embryo's organ of respiration, nourishment, and excretion. Blood barrier between mother and embryo diffuse across the membrane. Blood does not mix.

A floral formula consists of five symbols indicating from left to right:

thank you

and plz tell me what is the technique for writing floral formula

Ovary: female reproductive structure of flower that usually develops into the fruit

Ovule: egg-bearing structure of the flower that develops into a seed.

Flowers give a great sight to our eyes to enjoy.

However, they are also responsible for developing fruits and seeds in a plant.

When the ovary gets ripened, it develops into fruit and the ovules form the seeds.

Thus we can say every seed has an embryo waiting to grow.

Avariable number tandem repeat(orVNTR) is a location in agenomewhere a shortnucleotide sequenceis organized as atandem repeat. These can be found on manychromosomes, and often showvariationsin length (number of repeats) among individuals. Each variant acts as aninheritedallele, allowing them to be used for personal or parental identification. Their analysis is useful ingeneticsandbiologyresearch,forensics, andDNA fingerprinting

Thecentral nervous system(CNS) is the part of thenervous systemconsisting of thebrainandspinal cord. The central nervous system is so named because it integrates the received information and coordinates and influences the activity of all parts of the bodies ofbilaterally symmetric animals—that is, all multicellular animals exceptspongesandradially symmetric animalssuch asjellyfish—and it contains the majority of the nervous system.

Emergence of an organization is always through an evolutionary process. NDMA has also gone through the same stages. The Government of India (GOI), in recognition of the importance of Disaster Management as a national priority, set up a High-Powered Committee (HPC) in August 1999 and a National Committee after the Gujarat earthquake, for making recommendations on the preparation of Disaster Management plans and suggesting effective mitigation mechanisms. The Tenth Five-Year Plan document also had, for the first time, a detailed chapter on Disaster Management. The Twelfth Finance Commission was also mandated to review the financial arrangements for Disaster Management.

On 23 December 2005, the Government of India enacted the Disaster Management Act, which envisaged the creation of National Disaster Management Authority (NDMA), headed by the Prime Minister, and State Disaster Management Authorities (SDMAs) headed by respective Chief Ministers, to spearhead and implement a holistic and integrated approach to Disaster Management in India.

Separating, reducing, reusing, recycling and composting are good options for managing school waste. As a board of trustees, you have to find ways to get rid of school waste with the least negative effects on the environment. Incinerating and building waste pits on the school grounds can only be done by schools with no other options.

1. Separate waste

Separating waste is the first step in managing your school’s rubbish. Set up bins for the different kinds of waste, and make sure the right bins are used. You should have clearly labelled bins for glass, paper, plastic, cans and for organic waste.

2. Reduce waste

Avoid sending waste to a landfill. Landfills cause environmental problems, such as unpleasant smells and contaminants and toxins leeching into water and the air.

Educate staff and students about using other ways of disposing of waste, such as recycling, reusing and composting.

3. Reuse waste

Think about reusing waste around the school and the school community, including:

taking lost property to your local opportunity shop

using plastic bags as bin liners or as packaging (instead of bubble wrap)

having students make recycled paper and use shredded paper as bedding for pets.

4. Recycle waste

Contact your local council to find out what can be recycled in your area. Generally, you can recycle:

glass

paper and cardboard

cans

plastic.

Make sure recycle bins are used correctly and that the items are clean when they go in the bin.

For recycling to work, educating students and staff is essential. Some local councils help schools to set up recycling programmes and educate their staff and students.

5. Compost organic waste

Separate organic waste, like food scraps, plants, paper and lawn clippings, from other rubbish.

Use organic waste for composting and teach students about how it works. You can use the compost on the school gardens, saving on the cost of fertiliser and other chemicals. You could set up worm farms, which can be used to teach parts of the curriculum.

Significance of reproductive health in a society:

It prevents the spread of various sexually transmitted diseases such as AIDS, syphilis, etc.

Individuals with sound reproductive health produce better offspring which have better chances of survival.

Better sex education and awareness helps to maintain the population and prevent population explosion.

Unwanted and teen pregnancies can be avoided.

The reproductive health in India has improved tremendously over the past 50 years.

AIDS stands for Acquired immune deficiency syndrome which clearly states the deficiency and inability of an immune system to perform normally.

Immune system is a defensive system that protects us from the foreign invaders that causes diseases and infections but in case of AIDS, the immune system weakens and fail to fight any type of infection.
