Final answer:
During mitosis, ribosomes, lysosomes, peroxisomes, and soluble proteins are divided through cytokinesis (a). In plant cells, lysosome functions are carried out by vacuoles (a). Ribosome RNA components are synthesized in the nucleolus (d), and lysosomes and peroxisomes are both organelles (A).
Step-by-step explanation:
During mitosis, cell components such as ribosomes, lysosomes, peroxisomes, and soluble proteins are divided between the two new cells. This process is part of cytokinesis, which is answer choice (a) and it happens after the nucleus has divided. In plant cells, the function of the lysosomes is typically carried out by vacuoles (answer choice a). Synthesis of proteins occurs on ribosomes, they are then modified in the endoplasmic reticulum and tagged in the Golgi apparatus for distribution via vesicles (answer choice c). The RNA components of ribosomes are synthesized in the nucleolus (answer choice d).
Lysosomes and peroxisomes are organelles (answer choice A), which are essential for various cellular processes, such as breaking down waste and synthesizing certain biomolecules, respectively.
