What is the structure of the cell answer?
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
What are the functions of the cell short answer?
They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.
What is a cell in science PDF?
A cell is able to live and perform all its functions because of these organelles. These organelles together constitute the basic unit called the cell. It is interesting that all cells are found to have the same organelles, no matter what their function is or what organism they are found in.
What is the cell structure and function?
Cell Structure. The cell structure comprises individual components with specific functions essential to carry out life’s processes. These components include- cell wall, cell membrane, cytoplasm, nucleus, and cell organelles.

Who invented cell?
The cell was first discovered and named by ROBERT HOOKE in 1665.
What are the 2 main types of cells?
There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea. Prokaryotes—organisms composed of a prokaryotic cell—are always single-celled (unicellular).
What is a lysosome?
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts.
What is cell definition short?
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.
What is the full form of cell?

Why it is called a cell?
Hooke detailed his observations of this tiny and previously unseen world in his book, Micrographia. To him, the cork looked as if it was made of tiny pores, which he came to call “cells” because they reminded him of the cells in a monastery.
What is the structure of a cell class 6?
The basic components of a cell are cell membrane, cytoplasm and nucleus (Fig. 8.7). The cytoplasm and nucleus are enclosed within the cell membrane, also called the plasma membrane. The membrane separates cells from one another and also the cell from the surrounding medium.
What is the structure of a cell Class 7?
Cell membrane: A cell is composed of cell membrane, cytoplasm and nucleus. The cytoplasm and nucleus enclosed in the cell membrane together constitute the plasma membrane. It checks the transport of substances in the cell. Cell wall: In plants, an extra protective covering known as cellulose is present.
What is the structure of cell class 9?
A cell comprises several constituents, which perform unique activities that carry out different processes of life. These constituents are cell wall, cytoplasm, cell membrane, cell organelles, and nucleus.
Where is the cell structure?
The interior of human cells is divided into the nucleus and the cytoplasm. The nucleus is a spherical or oval-shaped structure at the center of the cell. The cytoplasm is the region outside the nucleus that contains cell organelles and cytosol, or cytoplasmic solution.
