Eukaryotic cells are those that have a membrane-bound nucleus and many membrane-bound organelles inside that function for the cell. Answer and Explanation:1 Plant cells are different from animal cells because they have cer...
cells, demonstrating the latent potential of untreated plant cells. The transcriptome of regenerating cells prior to stem cell activation resembles that of an embryonic root progenitor. Regeneration defects are more severe in embryonic than in adult root mutants. Furthermore, the signaling domains of ...

Most land trees, including redwoods, have xylem(木质部), or a system of small, tube-like cells. But without a pump, what makes water move through the xylem? Water evaporates (蒸发)from the leaves, pulling other water molecules(...
plant hormones called auxins, which control everything from the plant’s response to light and gravity to the ripening of fruit. Auxins might also be important in natural somatic embryogenesis: Embryos that sprout on top of veins near the leaf edge are exposed to relatively high levels of ...
Many of them live freely there. Some of the gentler ones, such as goats, sheep, geese, and deer, walk among the visitors who come to see them. Others are kept in large closed-in areas almost like their natural homes. All the animals there get care and love.1. Before 1977, the ...
