DEPARTMENT OF SCIENCE
 
 CELL
 
The basic components of the cell are Cytoplasm, Cell membrane, Nucleus and Organelles.
CBSE Class 8 Science Cell Worksheet 1
 
CELL MEMBRANE:
 
• The thin outer covering of cell is called the cell membrane or the plasma membrane.
 
• It separates the cell and its contents from the surroundings.
 
• It protects the cell and gives it shape.
 
• It is semi permeable and allows only water, minerals and some necessary substances to pass through it. It controls what passes in and out of the cell.
 
CELL WALL
 
• It is present only in plant cells.
 
• It is an additional wall outside the cell membrane.
 
• It is a thick wall made up of cellulose.
 
• It gives shape, support and protection to the plant cell.
 
• It provides rigidity to the plant cell to withstand the environmental effects.
  
CYTOPLASM
 
• The cytoplasm is a jelly like substance that makes up most of the inside of the cell.
 
• It has the nucleus and various other cell components called cell organelles.
 
NUCLEUS
CBSE Class 8 Science Cell Worksheet 2
 
• The nucleus is a spherical structure present inside the cell and is the control centre of the cell.
 
• It is surrounded by the Nuclear membrane which is also semi permeable.
 
• Inside the nucleus is a liquid called Nucleoplasm which has a smaller spherical structure called Nucleolus.
 
• The nucleoplasm has rod like structures called chromosomes that contain the genes (DNA) which help to transfer hereditary characters from parents to the offspring.
 
• The nucleus and the cytoplasm together make up the PROTOPLASM. IMPORTANT CELL ORGANELLES-Small structures present in the cytoplasm that perform different functions are called cell organelles.
 
MITOCHONDRIA
 
• Mitochondria are small rod like structures that provide energy and are therefore called as POER HOUSE of the cell.
 
ENDOPLASMIC RETICULUM
 
It is a network membranous tubes that connect the cell membrane with the nuclear membrane and helps to transport substances in and out of the cell.
 
GOLGI APPARATUS
 
These are membranous sacs that secrete useful substances such as enzymes and hormones and also store them.
 
PLASTIDS
 
These are disc shaped structures that often contain pigments present only in plant cells . They can be of three types, chloroplasts (that give green colour), chromoplasts (that give different colours ) and leucoplasts (that give no color).
 
RIBOSOMES
 
They are tiny structures either attached to the endoplasmic reticulum or scattered in the cytoplasm.They are associated with protein synthesis.
 
VACUOLES
 
These are sac like structures .In plant cells they are large and occupy most of the space in the cell, they store food, water and wastes. In animal cells they are small and help to remove wastes and also help in digestion.
