Biology Chapter 5: Cell Structure and Function

Plant cells have a cell wall made of cellulose and chloroplasts for photosynthesis.

Osmosis specifically refers to the movement of water across a semipermeable membrane, while diffusion involves the movement of particles from high to low concentration.

Stem cells in meristems allow for differentiation into various specialized cell types, supporting plant growth.

The movement of water across a semipermeable membrane from a region of high water concentration to a region of low water concentration.

The process by which cells become specialized with specific functions.

The movement of particles from an area of high concentration to an area of low concentration.

The movement of particles against a concentration gradient (from low to high concentration) which requires energy.

Plant cells have a rigid cell wall made of cellulose which provides support and shape.
