Answer:
1.A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangu
3.Cells are called the structural and functional unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. ... So, cell is the basic structural unit for all unicellular and multicellular organisms.
4.Both organisms are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane. The biggest difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus. They also have other membrane structures called organelles.
5.Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water.
6.Cytoplasm refers to the fluid that fills the cell, which includes the cytosol along with filaments, proteins, ions and macromolecular structures as well as the organelles suspended in the cytosol. In eukaryotic cells, cytoplasm refers to the contents of the cell with the exception of the nucleus.
7.The nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is commonly the most prominent organelle in the cell. The nucleus is surrounded by a structure called the nuclear envelope.
8.Nerve cells are the primary cells in the nervous system. They are responsible for relaying electrical messages to cells and tissues in other organ systems. This article discusses the functions and structures of nerve cells in the human body.
9.The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material.

Answer:
1:- Plant and animal cells have several differences and similarities. For example, animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes.
2:- Because chloroplast is the green plastid and in animal there is no any use of plastid so.
3:- Because all the function of life has been performed by thr cells. And the cells make the tissue,tissue make organ,organs make organ system and performing all
activities...
