Answer:
Refer to the attached image for correct labeling.
Explanation:
- The diagram is of a plant cell and its organelles.
- The nucleus houses the genetic material and controls all life processes.
- A plant cell contains one large vacuole in the center that stores water and nutrients.
- Chloroplast is the site for photosynthesis. It captures light and utilizes it and carbondioxide to produce glucose.
- Mitochondria are called the power house of the cell. Through a process called cellular respiration, they break down the glucose produced in photosynthesis into energy compounds such as ATP as well as oxygen and water.
- The endoplasmic reticulum is the site for protein sysnthesis. It contains two parts: the rough endoplasmic reticulum (RER) which contains ribosomes that synthesize proteins and the smooth endoplasmic reticulum (SER) which packages the proteins into transport vesicles.
- The nucleus contains the nucleolus that is the site for ribosome assembly.
- The cell membrane is a semi-permeable membrane that covers the cell and controls cellular transport.
- The cell wall is a hard, outer covering that protects the cell and maintains its structure and shape.

Answer: Adaptive immunity
Explanation:
The adaptive immunity is also known as acquired immunity. It is a sub system of the overall immunity.
It can defined as the immunity which is not present in the body when we are born. It develops in the body when it is exposed to the pathogens no matter it is natural or artificial.
The acquired immunity can develop in the body and makes the body susceptible to infections and develops prevention for the next time when the body will be exposed for the next time.
