Cell Division Quiz

How do animal cells typically complete cytokinesis?

• By forming a cell plate

• By budding

• By pinching the cytoplasm in two with a cleavage furrow

• By binary fission

Why can't plant cells pinch during cytokinesis?

• Because they have a flexible cell wall

• Because they lack a nucleus

• Because they have a sturdy cell wall

• Because they do not have cytoplasm

What forms during cytokinesis in plant cells that becomes the cell wall?

• Cell membrane

• Cell plate

• Chloroplast

• Mitochondria

How many chromosomes do humans have?

• 42

• 46

• 48

• 44

What are chromosomes composed of?

• RNA and protein

• DNA and RNA

• DNA and protein

• Protein and lipids

What structure holds the two identical chromatids together in a chromosome?

• Nucleus

• Centrosome

• Centromere

• Ribosome

What are somatic cells?

• Cells that contain no chromosomes

• Cells that only exist during mitosis

• Body cells

• Cells that are not found in humans

What does it mean when a cell is described as diploid (2n)?

• It contains half the number of chromosomes found in a somatic cell

• It contains a single set of chromosomes

• It contains two sets of chromosomes

• It contains four sets of chromosomes

In humans, what is the diploid number (2n)?

• 2n=23

• 2n=92

• 2n=46

• 2n=12

What are gametes?

• Cells that contain a full set of chromosomes

• Cells that contain half the number of chromosomes

• Cells that are found only in plants

• Cells that cannot fuse with other cells
