Explanation:

1. Mitosis es el proceso de división celular que produce células hijas idénticas, aumentando el número de células.
2. La xilema y el floema son los tejidos de transporte en plantas, mientras que las arterias y las venas lo son en humanos.
3. Los eucariotas pueden ser unicelulares o multicelulares y experimentan especialización y diferenciación celular.
4. La fertilización ocurre cuando un espermatozoide se une con un óvulo formando un cigoto, que se desarrolla en embrión y luego sufre diferenciación.
5. Los organismos multicelulares, como los humanos, son eucariotas con células especializadas y diferenciadas.

Answer:

1. B. To make more cells
2. A. Plant – Xylem & Phloem / Humans– Veins & Arteries
3. C. Eukaryotes are multicellular and undergo specialization and differentiation
4. B. Sperm + Egg → Zygote → Embryo → Differentiation
5. A. Multicellular are eukaryotes with specialization and differentiation of cells.
