Explanation:
"As humans grow, their bodies change.” The statement that best explains how humans grow is that cells undergo cell division.
When cells divide, thus brings about the making of new cells. This is referred to as cell division or cell reproduction. In this case, a single cell divides and then brings about two cells, then these two cells later make four cells .... This is unique and vital for every living organisms.
Answer:
d. xylem and phloem
Explanation: plants possess vascular bundles.these are bundles which includes xylem and phloem tissues and transport useful substances to various plant cells.
New Xylem and phloem are formed from the vascular cambium which divides into new cells .
Xylem and phloem are thin and slender with pipe-like structure.
The xylem transports water and dissolved nutrients to the cells where they are needed.
The phloem transports the product of photosynthesis (sugar) to parts what they are used up or stored .
Xylem cells are dead and consists in vessels,trachieds and xylem parenchyma.
Phloem cells are dead and consists in sieves cell, companion cells, phloem parenchyma and phloem fibres.
