Unit 2 Cell ultra structure Standards: 10 A. 7. 1 Differentiate between prokaryote and eukaryote cells. 10 A. 7. 2 Recognise and know the function of a nucleus, mitochondria, chloroplasts, endoplasmic reticulum and ribosomes 2

Activity 1 Write all words that you know about the cell. Circle Map Cell 5

Prokaryotes Eukaryotes 1 - Organisms Bacteria and blue-green bacteria Plants, animals and fungi 2 - Size Small, from 1 to 10 µm Large, from 10 to 100µm 3 - Nucleus No distinct nucleus as the main distinct nucleus with chromosome is not surrounded linear chromosomes by a nuclear membrane surrounded by a nuclear membrane 4 - Cell Walls Rigid cell wall containing the polysaccharide murein Present in plants , fungi but not containing murein 5 - Organelles Few organelles except for small ribosomes Many membranebound organelles such as mitochondria and chloroplasts 6 - Flagella, if present, lack microtubules Flagella have microtubules 10

Activity 2 Cut out the eggs and put them in the right basket in the next page ? Rigid cell wall Containing the polysaccharide murein Nucleus Surrounded by a nuclear membrane org Few an ell es Small, from 1 to 10 µm Large , from 10 to 100µm Bacteria And blue-green bacteria Plants, Animals and fungi No distinct Nucleus, not surrounded by a nuclear membrane 11

Find out which basket will have more eggs? ------------- EUKARYOTES PROKARYOTES 12

10 minutes (max) Question 3: Read the text below then answer the following questions. : ﺃﻘﺮﺃ ﺍﻟﻨﺺ ﺍﻟﺘﺎﻟﻲ ﺛﻢ ﺃﺠﺐ ﻋﻠﻰ ﺍﻷﺴﺌﻠﺔ ﺍﻟﺘﺎﻟﻴﺔ : ﺍﻟﺴﺆﺎﻝ ﺍﻟﺜﺎﻟﺚ REA DI ACTI NG VITY Life is specified by Genomes. Every organism, including humans, has a genome that contains all of the biological information needed to build and maintain a living example of that organism. The biological information contained in a genome is encoded in its DNA. and is divided into discrete units called Genes code for proteins that attach to the genome at the appropriate positions and switch on a series of reactions called gene expression 3 - Write a summary for the above text. ﺑﺄﺴﻠﻮﺑﻚ ﺍﻟﺴﺎﺑﻖ ﺍﻟﻨﺺ ﻟﺨﺺ - 3 ……………………………………………………………… 26
