Frequently Asked Questions
Define cell theory?
The cell theory was proposed by two scientists – Theodor Schleider and Matthias Schwann in the year 1839. According to this theory:
A new cell exists from pre-existing cells.
All cells have the same basic chemical structure.
The cell is the structural and functional unit of all living things.
Hereditary information is passed from parent cell to child cell.
The fundamental biochemical reactions of life take place within cells.
All living organisms existing on the planet earth are composed of one or more cells.
Which cell organelle is found only in animal cells?
Cell organelles that are present exclusively in animal cells are Centrosomes.
What are the functions of the Plant Cells?
The major functions of the plant cell are
They are the building blocks of plants.
Cell walls provide shape to the cell and protect the inner cell organelles.
Stores food in the form of energy.
Helps in the process of photosynthesis, transpiration, and other biological [process.
Help in the transport of water and nutrients from the roots and leaves to different parts of the plants.
How many types of cells are there?
There are different types of cells and are differentiated mainly based on their structure, functions, their compositions, etc. The two main types of cells are- Prokaryotes and Eukaryotes. This differentiation is based on the presence and absence of a nucleus.
