Cell Organelles Worksheet
6. Use the table above to fill in the chart
Complete the following table by writing the name of the cell part or organelle in the right
hand column that matches the structure/function in the left hand column. A cell part may
be used more than once.
Structure/Function
Cell Part
Stores material within the cell
Vacuole
Closely stacked, flattened sacs (plants only)
Chloroplast
The sites of protein synthesis
Ribosome / RER
Transports materials within the cell
Vesicle
The region inside the cell except for the nucleus
Cytoplasm
Organelle that manages or controls all the cell functions in a
eukaryotic cell
Contains chlorophyll, a green pigment that traps energy from
sunlight and gives plants their green color
Digests excess or worn-out cell parts, food particles and
invading viruses or bacteria
DNA
Chloroplast
Lysosomes
Small bumps located on portions of the endoplasmic reticulum
Ribosomes
Firm, protective structure that gives the cell its shape in plants,
fungi, most bacteria and some protests
Cell wall
Produces a usable form of energy for the cell
Mitochondrion
Packages proteins for transport out of the cell
Golgi bodies
Site where ribosomes are made
Nucleolus
The membrane surrounding the cell
Cell membrane or
plasma membrane
Provides support for the cell
Vacuole
Name for the collection of DNA in the nucleus of eukaryotic cells Chromosomes
Small hair-like structures used for movement or sensing things
Cilia
Longer whip-like structures used for movement
Flagella

7. All plants and animals carry out seven processes in order to stay alive. The table
below shows these seven LIFE PROCESSES.
Movement
This is easier to see in animals than in plants. Plants move very
slowly as they grow.
Respiration
Getting energy by reacting food with oxygen.
Sensitivity
Sensing changes around them and then responding.
Growth
Food is used to build up the parts of the body.
Reproduction
Producing offspring (young).
Excretion
Getting rid of poisonous waste chemicals from the body.
Nutrition
Plants make their own food by PHOTOSYNTHESIS. Animals
must feed on plants or other animals.
Use the name MRS GREN as an easy way to remember all 7 life processes.
Complete the sentences below.
1) It is usually easier to see movement in A nimals
2) We respire in order to produce Energy for the body.
3) Our ears, eyes and nose give us Sensitivity
4) If living organisms did not Reproduce
they would soon become
extinct (die out).
5) The kidneys Excrete a waste chemical called urea.
8. Fill in the missing words in the passage below.
Nearly all cells contain a membrane, …… nucleus…… and cytoplasm. There are
many ………… different …………… types of cells. They vary in their shape and
…………size…… depending on their functions (jobs). Each type of cell is well
………… adapted …………… (suited) to its function. In the human
…body……………… there are about twenty different types of cell, each has a certain
4
…………job…… to do. This makes the
body work much ……………better……… than if each cell was trying to do everything.
better
different nucleus
size
