10.3 Active Transport & Meiosis/Mitosis Study Guide

Some materials can move in and out of the cell membrane easily.

-Passive Transport

Active Transport

• Different from passive transport because it requires energy.

• Active transport is necessary to make particles move against their natural tendency.

• In active transport, particles move from less crowded (low concentration) to more crowded (high concentration) using ENERGY.

• ATP = ENERGY

Multiple Choice

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)

• Active uses ATP (energy) and passive does not need energy

• Active stores transport proteins and passive releases

• Active uses hormones and passive does not

Multiple Choice

Which diagram represents active transport?

Endocytosis

process by which the cell membrane envelops (engulfs) material that is too large to pass through the membrane and then pinches off inside the cell.

Exocytosis

The process by which the cell membrane removes material that is too large to pass through the membrane.

The material is surrounded by a membrane within the cell and then expelled by being pushed out of the cell.

Multiple Choice

Which cellular process removes large particles from the cell?

• endocytosis

• exocytosis

• diffusion

• osmosis

Multiple Choice

When cells form a vesicle to take in materials, which form of transport is occurring?

• endocytosis

• exocytosis

• diffusion

• osmosis

Multiple Choice

2 daughter cells are produced (one cell makes two)

• mitosis

• meiosis

• both

Multiple Choice

4 daughter cells are produced (one cell makes four cells)

• mitosis

• meiosis

• both

Multiple Choice

This diagram represents
