Answer:
chloroplast.
Explanation:
Chloroplasts are specialized organelles found in plant cells and some other organisms, such as algae. They are responsible for carrying out photosynthesis, the process by which plants convert sunlight, water, and carbon dioxide into glucose (energy) and oxygen.
Chloroplasts have a double membrane structure and contain their own DNA and ribosomes. They are green in color due to the presence of chlorophyll, a pigment that captures light energy for photosynthesis.
The presence of chloroplasts in plant cells allows them to produce their own food through photosynthesis, whereas animal cells do not possess chloroplasts and rely on obtaining nutrients from external sources.
In summary, chloroplasts are organelles found in plant cells but not in animal cells. They play a crucial role in photosynthesis, enabling plants to convert light energy into chemical energy and produce their own food
Answer:
Hypoplasia
Explanation:
Congenital hypothyroidism is most often the result of hypoplasia. Hypoplasia is the process of incomplete development of an organ or tissue in the body. Congenital hypothyroidism is insufficient thyroid hormone production in newborn infants. The underdevelopment of thyroid gland, occurs when the fetus is still in the womb and can be seen in everywhere from tooth enamel to the corpus callosum of the brain, heart, ovaries, various muscle groups, and other regions.
Congenital hypothyroidism is most often the result of thyroid dysgenesis or underdevelopment of the hypothyroid gland.
Congenital hypothyroidism can occasionally also be brought on by a problem with how thyroid hormone is made or by a lack of iodine during fetal development.
Genetic changes or other factors that obstruct normal thyroid gland development can lead to thyroid dysgenesis. TSH receptor gene, PAX8 gene, and NKX2-1 gene mutations are a few genetic changes linked to congenital hypothyroidism.
Mothers who do not get enough iodine, pregnant women who are exposed to radiation, and people who are exposed to certain drugs or chemicals are other causes that may cause thyroid dysgenesis.

The discovery of cells is most directly linked to the development of the microscope. This tool allowed early scientists to observe these tiny structures for the first time.
The discovery of cells is most directly linked to the development of the microscope. In the 17th century, Robert Hooke and Antonin Van Leeuwenhoek were among the first individuals to observe cells, made possible by the invention and significant improvements of optical microscopy during this era. Cells could not have been observed without this tool, as they are typically far too small to be seen by the unaided eye, cementing the major role that the development of the microscope played in discovering cells.
