Different kinds of cell

Question 1

Specialized cells

Answer 1

Some cells are specialized for different function (e.g bacteria)

Question 2

Bacterial cells

Answer 2

They do not have a nucleus (this is called prokaryotic)

Question 3

Specialized cells: egg cell

Answer 3

• Contains nutrients in the cytoplasm to supply the growing embryo
• Has a haploid nucleus that can fuse with another haploid nucleus to form a diploid zygote
• After fertilization, the membrane changes so that no more sperm cells can enter

Question 4

Specialized cell: Sperm cell

Answer 4

• Has a tail for swimming to the egg cell for fertilization.
• Many mitochondria around the base of the tail release the energy needed to propel the cell
• Has haploid tissue that fuses with the egg nucleus to form a zygote
• The across me contains digestive enzymes to help penetrate the membrane of the egg

Question 5

Specialized cell: Ciliated cell

Answer 5

• Move things along the tube such as mucus

- Has a lot of cilia to help move the mucus (containing dirt and bacteria) away from the lungs
