the alternation of sexual reproduction and asexual reproduction in certain plants and animals

a response of an organism or part of an organism to touch, such as the coiling of a vine around an object

22.
a region of undifferentiated plant cells that are capable of dividing and developing into specialized plant tissues

23.
in leaves, the tissue between epidermal layers, where photosynthesis occurs

24.
a group of elongated, thick-walled plant cells that support the growth of leaves and stems
