Cell drawing P (model, not to scale)
An animal cell stretched into an oval. At each end sits a group of 6 chromosomes, each group unwinding into long thin threads. A new nuclear envelope is forming around each group. A shallow groove pinches in at the middle of the cell.
Bo labels drawing P of a dividing animal cell. Which stage of mitosis do its chromosomes and nuclei show?
- Anaphase
- Telophase
- Cytokinesis
- Prophase
Cell drawing P (model, not to scale): a plant cell with a cell wall. The nuclear envelope is gone. Esme labels drawing P of a dividing plant cell. Which stage of the cell cycle does it show?
- Interphase
- Anaphase
- Prophase
- Metaphase
“model, not to scale” Jun counts the rods in drawing P of a cell at metaphase. How many chromosomes does the cell have?
- 3 chromosomes: the pairs are counted in twos
- 12 chromosomes: each rod counts as a chromosome
- 18 chromosomes: 12 rods plus 6 centromeres
- 6 chromosomes: each joined pair counts as one
Cell card (model data)
The cell has 6 chromosomes at metaphase, each made of two sister chromatids. In late anaphase the sister chromatids have separated and are moving to opposite ends. Counting rule (OpenStax): once separated, each chromatid is counted as one chromosome.
Luz follows the same model cell into late anaphase. Counting each separated chromatid as a chromosome, how many chromosomes are in the cell, and how many at each end?
- 12 in all, 12 at each end
- 12 in all, 6 at each end
- 24 in all, 12 at each end
- 6 in all, 3 at each end
Cycle wheel (model, not to scale)
a circle cut into arcs in order: G1, S, G2, M (mitosis) and cytokinesis. A drawn cell sits in the M arc: a plant cell with 6 X-shaped chromosomes in a row across the middle and spindle fibers attached from both ends.
Milo sees the cell drawn on the wheel. What happens to the chromosomes next?
- Their sister chromatids separate and move to opposite ends
- They condense into thick X shapes from loose chromatin
- They line up in a row across the middle of the cell
- They unwind inside re-forming nuclear envelopes
Noah sees the cell drawn on the wheel. Which stage of mitosis comes next?
- Telophase
- Cytokinesis
- Prophase
- Metaphase
Cycle wheel (model, not to scale)
a circle cut into arcs in order: G1, S, G2, M (mitosis) and cytokinesis. A drawn cell sits near the end of the M arc: a plant cell with two new nuclei, one at each end, each inside a nuclear envelope. In the middle a thin new wall (a cell plate) has started to grow outward from the center.
Pia sees the plant cell drawn on the wheel. What happens next at the middle of the cell?
- The chromosomes line up again across the middle
- The cell plate grows outward until it reaches the cell wall
- The spindle fibers pull the new wall toward each end
- A cleavage furrow pinches the cell in two
Ren compares drawings P and Q of cells dividing their cytoplasm. Which pair of labels is right?
- P is a plant cell with a cell plate; Q is an animal cell with a cleavage furrow
- P is an animal cell with a cleavage furrow; Q is a plant cell with a cell plate
- P is a plant cell with a cell plate; Q is a plant cell with a cleavage furrow
- P and Q are animal cells; P has a cell plate and Q has a cleavage furrow
Tala watches a plant cell finish mitosis. How does the plant cell divide its cytoplasm?
- A cleavage furrow pinches the membrane inward until the cell splits
- Vesicles fuse at the middle into a cell plate that becomes a new wall
- Spindle fibers grow into a new wall that separates the two nuclei
- The cell wall breaks down so the two halves can drift apart
