Question

organs in the endocrine system are:
hormones and glands
lungs
heart and blood vessels
brain, spinal chord, neurons

the xylem in plants transports:
chloroplasts
lons
sugar
water

the phloem in plants transports:
chloroplasts
lons
sugar
water

Explanation:

• First question: The endocrine system consists of glands that secrete hormones. Lungs are part of the respiratory system, heart and blood vessels are part of the circulatory system, and brain, spinal cord, and neurons are part of the nervous system.
• Second question: Xylem is a vascular tissue in plants that transports water (and minerals) from the roots to the rest of the plant. Chloroplasts are organelles for photosynthesis, ions can be transported in various ways but xylem's main role is water transport, and sugar is transported by phloem.
• Third question: Phloem is the vascular tissue that transports sugar (produced by photosynthesis in leaves) to other parts of the plant. Chloroplasts are not transported by phloem, ions have other transport mechanisms, and water is mainly transported by xylem.

Answer:

• First question: Hormones and glands
• Second question: Water
• Third question: Sugar
