Paramecium is a unicellular organism with a shape resembling the sole of a shoe. It ranges from 50 to 300um in size which varies from species to species. It is mostly found in a freshwater environment.
It is a single-celled eukaryote belonging to kingdom Protista and is a well-known genus of ciliate protozoa.
As well, it belongs to the phylum Ciliophora. Its whole body is covered with small hair-like filaments called the cilia which helps in locomotion. There is also a deep oral groove containing not so clear oral cilia. The main function of this cilia is to help both in locomotion as well as dragging the food to its oral cavity.
Answer:
ovule
The fertilized ovule becomes the seed, and the ovary becomes the fruit. Petals are also important parts of the flower, because they help attract pollinators such as bees, butterflies and bats. You can also see tiny green leaf-like parts called sepals at the base of the flower.

Answer:
B cellular respiration
Explanation:
As mentioned in the question, While running a race, a person's muscles need a constant supply of ATP. This clearly indicate that question is not about a plant but about a human being. Now let us look at the available options:
A) Photosynthesis:
The process of photosynthesis takes place in green plants which is a source for the preparation of glucose or food for them. Moreover, plants just like animals also depend on the process of respiration for the generation of energy in the form of ATP. Therefore, photosynthesis cannot be the right option.
C) Calvin cycle:
Calvin cycle is the process that is also called as dark reaction of photosynthesis. It is second step of photosynthesis which takes place during night when CO2 is used for the preparation of glucose-. Since Calvin cycle is part of photosynthesis, it takes place only in plants and not in humans.
B) Cellular respiration:
Cellular respiration is the key process in which food we eat is broken down through series of reactions to produce energy in the form of ATP. When we do exercise or run fast, our body needs a rapid input of energy to meet the body's energy demands at that moment. Therefore, the rate of cellular respiration increases. This makes cellular respiration right option.
