Which of the following substance is not present in the cell?
Cells are made of a variety of chemical substances - proteins, carbohydrates, fats or lipids and so on. Soil is not a component of cell.
A prokaryotic cell ranges in size from:
Find the incorrect statement regarding cell organelles from the following:
An eukaryotic cell ranges in size from:
eukaryote, any cell or organism that posseses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus , in which the well defined chromosomes are located.
Which is the control centre of the cell?
The fluid content inside the plasma membrane of a cell is called
Cytoplasm is the viscous gel like substance which acts as the base or site of all metabolic activities occurring inside the cell.
Nucleoid is a feature of
Animal cells do not show the presence of
Animal cells do not have cell Wall because they do not need them. Cell walls , which are found in plant cells , maintain cell shape, almost as if each cell has its own exoskeleton.
Which statement is false with respect to multi-cellular organisms?
Unicellular organisms are made up of only one cell that carries out all the functions needed by the organism, while multicellular organisms use many different cells to function. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions
Cellular organelles containing hydrolytic enzymes are called
Prokaryotic cells do not have:
How does protoplasm differ from cytoplasm?
Protoplasm is a colour less material that has a living part of a cell which includes the cytoplasm, nucleus, and other organelles.
Cytoplasm is a substance which is similar to jelly and is surrounded by the nucleus within the cell membrane.
Prokaryotic cell contains:
Most prokaryotes contain one circular chromosome. DNA communicateswith the cytoplasm- so it allows direct connection to the transcription and translation. Contain only one copy of the gene. Non essential genes are stored outside of chromosome - in Plasmids.
The presence of various cell organelles within the cell helps in
In order for cells to function and survive, their organelles work together to carry out specific tasks and perform specific roles. Each organelle has its own role that contributes to the survival of the cell. This is called thr Division of labour.
Cell wall is mainly made up of
