Cells & Specialised Cells

?
How is the nucleus adapted to its function?
It contains genetic material that control the activities of the cell.
1 of 16
How is a cell wall adapted to its function?
It is made of cellulose which helps it support and strengthen the cell.
2 of 16
How is the cytoplasm adapted to its function?
It is a gel-like substance where most of the chemical reactions in the cell happen. It contains enzymes to control these chemical reactions.
3 of 16
How is a vacuole adapted to its function?
It contains cell sap (weak solution of sugars and salts), it maintains internal pressure to support the cell.
4 of 16
How are mitochondria adapted to its function?
Reactions for respiration take place here therefore this enables it to produce the energy required for the cell to work.
5 of 16
How are ribosomes adapted to their function?
The translate gentic material to synthesise protein.
6 of 16
How is the cell membrane adapted to its function?
Hold together the cell, as it surrounds the cell it can control what enters and leaves the cell.
7 of 16
How are chloroplasts adapted to their function?
Contains chlorophyll, photosynthesis take place here.
8 of 16
Name the subcellular structures in animal cells.
Cell membrane, nucleus, ribosomes, mitochondria and cytoplasm.
9 of 16
Name the extra subcellular structurres that a plant cell has but the animal cells do not.
Cell wall, large vacuole and chloroplasts.
10 of 16
Name the subcellular structures foound in a typical bacterial cell.
Chromosomal DNA, ribosomes, cell membrane, plasmid DNA and flagella.

What is the difference between eukaryotic cells and prokaryotic cells.
Eukaryotic cells are complex and contain DNA inside a nucleus. Prokaryotic cells are much more simple and small.

How are sperm and egg cells specialised to their function?
Sperm cell- flagella, middle section with lots of mitochondria, acrosome with enzymes and haploid nucleus. Egg cell- nutrients in cytoplasm, haploid nucleus and membrane changes structure right after fertilisation.
13 of 16
What are specialised cells?
Cells specialise for a specific function.
14 of 16
What is haploid cell? Diploid cell?
Haploid- 23 chromosomes, half the maount of chromosomes. Diploid- 23 pairs i.e. 46 chromosomes.
15 of 16
How are ciliated epithelial cells adapted to their function?
Line the surfaces of organs, cilia (hair-like structure) beat substance in one direction to move them along the surface of the tissue.
