Q

why dicots have woody stems and most monocots have herbaceous stems?

A

Dicots often have woody stems because they undergo secondary growth, producing vascular tissues that increase stem diameter. This growth results in the formation of wood. Most monocots, on the other hand, exhibit primary growth only, leading to herbaceous stems without the development of secondary tissues like wood.

Q

arise as swollen-ends of stolon

A

tuber

18
Q

store carbohydrates/ food underground to survive a drought or cold period

A

corm

22
Q

store starches to fuel growth and help plants survive unfavourable conditions

A

corm

23
Q

a slender whiplike or threadlike strand, produced usually from the node of a stem, by which a vine or other plants may climb

A

tendrils

24
Q

provides support and allows other plants to find an area within more light to grow

A
