Question

State the exact location of the following :
(i) Chloroplast.
(ii) Incus.
(iii) Corpus callosum.
(iv) Guard cells.
(v) Pulmonary semilunar valve.

Answer 1

Hint: Higher plants have more processes involved in photosynthesis, but it is fundamentally the same. It is a physicochemical process in which organic compounds are synthesized using sunlight. Oxygen is released into the atmosphere as a result of this process.

Complete answer:
i) Chloroplast: Chloroplasts are organelles in plant and algal cells that perform photosynthesis, in which the photosynthetic pigment chlorophyll captures energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while releasing oxygen from water. They are found along the inner margin of the cell membrane and in the green parts of plant cells.
ii) Incus: The incus is the middle of the three ossicles, articulating anteromedially with the head of the malleus to form the incudomalleolar joint and anteromedially with the stapes to form the incudostapedial joint. It is located between the malleus and the stapes in the middle ear.
iii) Corpus Callosum: The corpus callosum, also known as the callosal commissure, is a wide, thick nerve tract that runs beneath the cerebral cortex and is made up of a flat bundle of commissural fibers. Only placental mammals have the corpus callosum. Corpus Callosum is located between the two lobes of the cerebrum or cerebral hemispheres.
iv) Guard cells: These cells are found connected to adjacent epidermal cells and are important constituents of stomata.
v) Semilunar pulmonary valves: The semilunar valves are pocket-like structures attached to the pulmonary artery and aorta as they exit the ventricles. The orifice between the right ventricle and the pulmonary artery is protected by the pulmonary valve. At the base of the pulmonary trunk, these valves are found.

Note:
In some organisms, chloroplasts play an important role in the photosynthesis process.
The incus is the middle of three small bones in the middle ear, also known as the "anvil." Vibrations are transmitted from the malleus to the stapes via the incus. After that, the vibrations travel to the inner ear.
People who are born without a corpus callosum face numerous difficulties. Some people have other brain abnormalities as well—and as a result, they have a higher risk of developing dementia.
The pulmonary artery and the right ventricle are separated by this valve. Opens to allow blood from the right ventricle to be pumped to the lungs (via the pulmonary artery), where it will be oxygenated. Stops blood from flowing backward from the pulmonary artery to the right ventricle.
