To observe mitosis, what part of a plant should a student look at under a microscope?
a. epidermis of a leaf
b. xylem from a tree trunk
c. tip of a shoot
d. phloem from the stem of a plant

(C). tip of a shoot  

Explanation:

Mitosis can be defined as a type of cell division, which involves formation of two identical daughter cells from a parent cell having same genetic makeup.

If a student wants to study mitosis, he should use tip of shoot as it contains meristematic cells and is a rapidly growing part of the plant. It contains many cells that are present in different mitosis stages.

Thus, the correct answer is option (C).

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
