Question

1. what is the structure that holds the sister chromatids together before they separate during anaphase? centriole chromosomes centrosome centromere question 14 1 pts 14. in comparing an animal cell to a plant cell during cytokinesis, what is the key difference you would observe? plant cells form a cleavage furrow, while animal cells form a cell plate. plant cells form a cell plate, while animal cells form a cleavage furrow cytokinesis does not occur in plant cells. animal cells have a cell wall, while plant cells do not.

Explanation:

Question 13

• Centriole: Organelles involved in cell division spindle formation, not holding chromatids.
• Chromosomes: Structures made of DNA and proteins, sister chromatids are part of a chromosome.
• Centrosome: Organelle that organizes microtubules, not the holding structure.
• Centromere: Region that holds sister chromatids together before anaphase.

• In animal cells during cytokinesis, a cleavage furrow forms (constriction due to actin - myosin ring).
• In plant cells, a cell plate forms (vesicles fuse to create new cell wall and membrane).
• Cytokinesis occurs in both plant and animal cells.
• Plant cells have a cell wall, animal cells do not.

Answer:

centromere
