organ system

A group of organs working together.

A group of the same kind of cells working together.

organ

diffusion example

An example of this is: A drop of food coloring spreads out in a beaker of water

osmosis example

An example of this is: When wilted celery is soaked in water it becomes crisp again.

cell cycle

Cells undergo a regular sequence of growth and division, that is called the _________________.

oxygen

Cellular respiration is the process by which living organisms use ______________ to help break down food molecules to release energy.

products

Oxygen and glucose are the _________ of photosynthesis

cytokinesis

The division of the cell's cytoplasm is called...

chromosomes

These are made of DNA, the hereditary material that controls the cell's activities.

diffusion

This allows different materials to move in and out of cells from a higher concentration to a lower concentration.

cell membrane

This cell structure is "selectively permeable," allowing certain substances to enter or leave the cell.

reactants

Water and carbon dioxide are the ________ of photosynthesis.

osmosis

When water diffuses into or out of a cell.

chloroplasts

Where photosynthesis takes place in eukaryotic cells.

cellular respiration

glucose + oxygen --> carbon dioxide + water + energy
