Cellular Respiration, Photosynthesis, and Cell Types: Biology Basics

What is the equation for cellular respiration?

Oxygen + food (glucose) → Carbon dioxide + water

What is the equation for photosynthesis?

Carbon dioxide + water + sunlight → Oxygen + food (glucose)

What is the function of xylem cells?

Transporting water

What is the function of phloem cells?

Transporting food

What is the organization of biological structures from smallest to largest?

Cells → tissues → organs → organ systems

Name a type of animal body cell.

Examples include blood cells, brain cells, bone cells, nerve cells, muscle cells, storage cells, and skin cells.

What is an example of a unicellular organism?

Amoeba

What is the lifespan of an amoeba?

2 days

How do amoebas obtain water?

Water enters the amoeba by osmosis.

What organelle in amoebas helps prevent them from bursting?

A special vacuole that pumps water out of the cell.

What type of organisms can amoebas be classified as?

Carnivores, omnivores, and herbivores.

How do amoebas move?

By changing shape and forcing cytoplasm into extensions called pseudopods.

What structure allows E. coli bacteria to move?

A flagellum, which looks like a tail and rotates.

What organelle do paramecia use for movement?

Cilia, which are tiny hairs that push the organism along.

What process do cells undergo to reproduce?

Cell division, where cells split in half to form two smaller cells.

What happens to the nucleus during cell division?

The nucleus splits first.

What causes cells to die?

Damage, lack of food or water, or reaching the end of their lifespan.
