Understanding Cells

What are the main components of a cell's structure?

• Cell membrane, cytoplasm, nucleus, organelles (e.g., mitochondria, ribosomes, endoplasmic reticulum)

• DNA, RNA, proteins

• Cell wall, chloroplasts, vacuoles

• Blood, bones, muscles

What are the two main types of cells?

• Animal cells and Plant cells

• Bacterial cells and Viral cells

• Prokaryotic cells and Eukaryotic cells

• Stem cells and Germ cells

What is a characteristic feature of prokaryotic cells?

• Lack of a membrane-bound nucleus

• Presence of a cell wall

• Complex DNA structure

• Membrane-bound organelles

How do eukaryotic cells differ from prokaryotic cells?

• Eukaryotic cells lack a cell membrane.

• Eukaryotic cells have a nucleus and organelles; prokaryotic cells do not.

• Eukaryotic cells are smaller than prokaryotic cells.

• Prokaryotic cells have a nucleus and organelles.

What are the main stages of mitosis and meiosis?

• prophase, metaphase, anaphase, telophase, cytokinesis; prophase I, metaphase I, anaphase I

• prophase, metaphase, anaphase; prophase I, metaphase I, anaphase I

• Mitosis: prophase, metaphase, anaphase, telophase; Meiosis: prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, telophase II.

• prophase, metaphase, anaphase, telophase; prophase I, metaphase II, anaphase II, telophase II
