Test yourself on The Cell using this revision aid - answers are below


The Cell

1) Ribosomes make proteins but what controls this activity (i.e. what tells them to do this?)

 2) Mitochondria are called the “power – houses“ of the cell. Why?

 3) Why is the cell membrane semi – permeable?

 4) What 2 substances is the cell membrane made of?

 5) How do lysosomes work?

 6) What information do genes carry?

 7) Where are genes found?

 8) What happens to the proteins that the golgi apparatus packages up?

 9) Why is the nucleus important to the cell?



1) How many daughter cells does mitosis produce?

2) How many chromosomes do these daughter cells have?

3) What is mitosis used for?

4) How many chromosomes do the daughter cells have after meiosis?

 5) True or false?

 a. there are four daughter cells produced after meiosis

 b. the male mature sperm contains only the y chromosome

 c. meiotic division occurs in sex cells only ( sperm and ova )

How did you get on? Check your answers below

The Cell

Messenger RNA carries a copy of a gene from DNA in the nucleus, and moves out of the nucleus to the ribosomes, where the genetic code it carries is translated and a specific protein is made.

Mitochondria are often called the “powerhouses” of the cell because they are the site where glucose is broken down to release the energy required to “power” cellular functions.

Generally, the membrane is permeable to small molecules such as water, glucose, and amino acids that the cells needs and to waste that the cell must excrete. Large molecules such as glycogen, which the cell wants to keep as a storage form of glucose, cannot pass.

Phospholipids and protein

They have hydrolytic enzymes that digest food particles, invading  bacteria and cell debris such as worn out organelles

They carry the hereditary information of the cell. Each gene carries the code for a single protein

Genes are found in DNA, they are one small section of DNA

After modification, the proteins are transported to elsewhere in cell or to the cell membrane for transport outside the cell

The nucleus contains DNA; it is therefore the control centre of the cell. DNA contains "instructions" needed for cell reproduction and for making proteins that control all the reactions that take place in the cell and other cell functions.

Cell Division

1) Two

2) 23 pairs, which equals 46

3) Growth and repair/replacement of damaged tissues

4) 23 single chromosomes

5) a) true   b) false   c) true
