Pg no. 59 Ans no.1 :- Cell was discovered by Robert Hooke in year 1665. He magnified the thin slice of cork under his own-made microscope🔬 he observed small honeycomb like structures, he named them cell. He observed a dead cell. Ans no.2 :- Cell is called the structural and functional unit of life bcuz it perform all the basic functions in the body and give structure to the body. Hope u like the ans. 😊
ANS 2;- cells are called structural and functional unit of life because all the living organisms are made up of cell and also all the functions taking place inside the body of organism are performed by cells .
Ans 2- The cell is known as the structural and functional unit of life because all living beings are formed of cells. Cells are very important for performing various life processes which are required for sustaining life on earth. Moreover, cells give form and structure, process nutrients and make it into usable energy.
1. Robert hook (1665) while hook made this chance observation through a self designed microscope. 2. A cell is capable of carrying outall life process,such as nutrition, excretion, respiration, etc . Hence it is called as the functional unit of life.
1. Who discovered cells,and how? ~ In 1665,Robert Hooke discovered dead cell while observing a thin slice of cork by primitive microscope. He sawed honeycomb like structure and named it cell. 2.Why cell is called the structural or fundamental unit of life? ~Cell is called the structural or fundamental unit of life because all organisms are made up of cells and cells perform various activities which are essential for life.
The cell is called the structural and functional unit of life because every living organism is made up of with the combination of these small cells , thus it is also called the basic unit of life .. every single part of the cell performs different different functions and has a fixed work .... 👍👍🙏🙏🙏
1.Cell was discovered by Robert hook, who was an English botanist. He used a self- designed microscope, took a cork slice & observed it under that microscope. He found there are many little box or compartment like structure. So he named it cell which is a latin word means little room or compartment. 2.The cell is called the structural and functional unit of life because all living organisms are composed from cells & these cells play very crucial role for performing various activities required for retaining life.

You are the precious person and precious teacher in this world 🌎 the I like your way to explain 💖 you were telling each and every thing ❤ You nice Keep going Bro ❤
Ans.1. Robert Hooke discovered the cell, while observing the thin slice of cork. Ans.2. Because the human body is made up of cells and because of cells every organisms perform many activities.
1. Robert hooke discovered dead cell in 1665 2.The cell is called the structural and functional unit of life as all living organisms are made up of cells and The cell is our most essential body forming unit. Each organ in our body is made of cells. Cells divide and multiply to form new organs that's why it is called structural and functional unit of life My imagination for this question ~Puja khedkar Thank you sir👍
cell is discovred by robert hook in 1665 when he was observing a slice of cork under his self designed microscope , he saw very little compartments and coined the term cells for these compartments.

2) The cell is the basic unit of life. All organisms are made up of cells. Each cell has got its certain components which perform their specific function basically known as cell organelle. A cell is able to perform its function only with the help of these organelles. A cell is able to live or perform its function within a body with cell organelle. Therefore, each cell organelle constitute together to make a cell.
Answer 2. Cell is 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.
Page no.59 1 Ans = Robert hook discovered cell and he used self designed microscope to observe cell in a cork slice. 2 Ans = Cells taking function and structure that's why cell called the structural and functional unit of life .
Ans 2: Cell is called structural unit because body of all the organisms is made up of cells. It is functional unit life because all the functions of body (physiological, biochemical, genetic and other functions) are carried out by cells
Ans.1 In 1665 Robert Hooke discovered cells while examining a thin slice of cork through a self -designed microscope.while observed a thin slice of a cork.
A. Robert hooke discovered the cell. He discovered it when he placed a thin piece of cork under the microscope and saw that there were structures like room in monasteries so he called them cells. In Latin small rooms are called cells. B. Cells are known as the structural and functional units of human body because they forms the structure of human body and functions according to the requirements without them human body cannot be formed.
1. Cell is called the structural and functional unit of life because all organism are composed of 1 or more cells, and vital functions of an organism occur with in cell. Cell contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cell.😀
Ans1: cell were covered in 1665 by an botanish, Robert hooke he used a primitive microscope to obserb cell of cork slice. Ans2: Cell cinstitude are various component of plant and animal cell. A cell is a smallest unit of life and it is capable for all living functions cell are the building block of life that's why the cell are referred to as a basic structure and the functional unit of life . All cell vary in their shape, size and activity which they are performed. The shape and the size of a cell is related to a specific function which they perform.
Ans1 Cell were first discover by Robert hoke in 1665 while obverse cork in units Pitmitves macroscopic all cell varely functional shape size activities on the three region nucles plasma membrane Coroplatyi Ans 2 All living from composd of small Maroscopi units is called cell is a basic building from structural and function unit cell organisms
1. Roobert hooke Discover the cell while observing a thin slice of cork 2. The cell cled the structural and functional unit of life because all living being are made of cell
1st answer= Robert Hooke in 1665 and In cork of a bark of tree 🎄🌴 2nd answer= Cell is a structural unit of life because all living organisms are composed or made up of cells And functional unit of life is because all the functions or chemical reaction in our body is performed inside cell 😀
Answer 1 . Robert Hooke discovered cells in 1665 while examining a thin slice of cork through a self designed microscope. He show that the cork, resembled the structure of a honey comb consisting of many little compartments. These small boxes are called cell.
1 ans Robert Hooke discovered the cells with the help of his self microscope . In 1665 Robert Hooke examining a thin slice of cork when observe so see make honeycomb it many consistence of a cell
QUESTIONS ✌️ Q. 1] Who discovered cell and how ? Cell was first discovered by Robert Hooke in 1665. He observed the cells in a cork slice with the help of primitive microscope. Q. 2] Why cell is called Structural and functional unit ? Cells form the structure of an entity. A group of cells form a tissue, further an organ and ultimately an organ system. They perform fundamental functions and life processes such as respiration, digestion, excretion etc in both unicellular and multicellular entities. They perform all the activities independently. Hence, cells are referred to as structural and fundamental units of life.
In 1665, Robert hook discovered cells while examinig a thin slice of cork through a microscope.He observed that cork resemble the structure of a honeycomb consisting of numereous boxes.Robert Hook refered these boxes as cells.
cell is called the fundemental unit of life because cells are combined to form tissures and tissues are combined to form organs and tissues are combined to form organ system and then a new organisms will be form.

Cells form the structure of an entity. A group of cells form a tissue, further an organ and ultimately an organ system. They perform fundamental functions and life processes such as respiration, digestion, excretion etc in both unicellular and multicellular entities. They perform all the activities independently. Hence, cells are referred to as structural and
