Chapter 3 From a Cell to an Organism Test

Front

What phase of the cell cycle does a cell spend most of its time in?

Back

Interphase is the phase where a cell spends most of its time, preparing for cell division.

Front

What is a unicellular organism made of one eukaryotic cell called?

Back

A unicellular organism made of one eukaryotic cell is called a eukaryote.

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs in the ground tissue of plants.

Front

What are unspecialized cells in plants similar to animal stem cells called?

Back

Unspecialized cells in plants are grouped in areas called meristems.

Front

During which phase are sister chromatids pulled apart by spindle fibers?

Back

During Anaphase, sister chromatids are pulled apart by spindle fibers towards opposite poles.

Front

What is the main function of interphase in the cell cycle?

Back

Interphase is responsible for cell growth, DNA replication, and preparation for mitosis.

Front

What is the role of meristems in plants?

Back

Meristems are regions in plants where unspecialized cells can divide and differentiate into various cell types.

Front

What is the significance of ground tissue in plants?

Back

Ground tissue is important for photosynthesis, storage, and support in plants.

Front

What happens during cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell divides into two daughter cells.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
