Biology - Animal/ plant cells & specialised cells

What is a cell membrane?

Controls the movement of substances into and out of the cell

What is a cell wall?

Contains cellulose, provides structure & protection (plant cell only)

What is mitochondria?

Site of respiration and provides energy

What is a cytoplasm?

Jelly like material containing dissolved nutrients, salts and structure called organelles. Controls reaction of the cell

What is a chloroplast?

Site of photosynthesis & chlorophyll making the plant green (plant cells only)

What is a ribsome?

Site of protein synthesis

What is a nucleus?

Contains genetic material (DNA) and controls cell activity

What is the vacuole?

Filled with cell sap, waste products end up here

What are cells?

The building blocks of all living organisms

What are specialised cells?

Cells that have adapted to perform a particular task. Cells become specialised during differentiation

What is diffrentiation?

When an unspecialised cell becomes a more specialised cell type.When a cell differentiates it develops a structure and internal features which enable it to carry out its function
