Answer:
Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.
Explanation:
When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.
The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.
The role of ATP synthase in photosynthesis is to transports a proton down the gradient and uses the energy to complete the phosphorylation of ADP to ATP.
Further Explanation:
Photosynthesis starts with the absorption of light or solar energy by the plant pigments called chlorophyll. The activated chlorophyll molecule helps in the electron transfer from one acceptor to another forming a chain.
The first phase of photosynthesis the light-dependent reaction in which the absorbed light is utilized to produce molecules carrying energy that is used in the second phase to form carbohydrates by reducing carbon dioxide. The first phase occurs in the grana region of the chloroplast and involves the transport of electrons through photosystem II (PS II) followed by photosystem I (PS I). The energy gained by the chlorophyll molecule is transferred to PS II in the form of electrons. These electrons are passed on further through a series of electron transporter or carrier from PS II to PS I. In photosystem I, finally, the electron is gained by NADP+ to form NADPH.
The ATP synthesis is produced by the use of proton motive force this reaction is catalyzed by ATP synthase. This a multiprotein synthase is also well-known as F0 F1 complex .The ATP molecule is synthesized when proton flow back from the inner membrane down the electrochemical proton gradient . ATP synthase has two components F1 ATPase and F0 which is embedded in the inner membrane and contain alpha, beta and C unit.
As the electrons travel along the electron transport chain, energy is released which helps in the pumping of protons (ions) into the lumen from the stroma through the thylakoid membrane. A proton gradient is developed which allows the movement of protons back to the stroma which in turn results in the formation of ATP through membrane-bound ATP synthase
The second phase of the photosynthesis is the dark reaction or the light-independent reaction happens in the stroma and utilizes the products formed during the light-dependent phase.

Answer:
Animal-like protists are called protozoa. Most consist of a single cell.
Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed.
Fungus-like protists are molds. They are absorptive feeders, found on decaying organic matter.
Explanation:
The thylakoids contain two photosystems. They are the site of light-dependent reactions and are a <span>membrane-bound compartment inside chloroplasts and cyanobacteria.</span>
