Diffusion across the membrane with no ATP being expended

• active transport

• passive transport

• endocytosis

• exocytosis

All cells come from __________________.

• old cells

• their parents

• pre-existing cells

• the nucleus

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

• diffusion

• endocytosis

The process of taking material into a cell within vesicles that bud inward from the plasma membrane.

• exocytosis

• osmosis

• endocytosis

• diffusion

When a cell uses ATP to move molecules across the membrane.

• diffusion

• osmosis

• passive transport

• active transport

If a cell contains a nucleus, it must be _________.

• prokaryotic

• eukaryotic

• plant

• animal

The diffusion of water across a selectively permeable membrane.

• diffusion

• osmosis

• endocytosis

• exocytosis

The organelle that modifies, stores and routes proteins and other chemical products to their next destination within the cell

• lysosomes

• endoplasmic reticulum

• golgi apparatus

• nucleolus

In order to export proteins out of the cell, a vesicle containing the protein fuses with the plasma membrane and spills its content outside the cell.

• endocytosis

• exocytosis

• facilitated diffusion
