Plants cells have DNA that helps in making new cells, hence enhancing the growth of the plant. the DNA is enclosed within the nucleus, an enveloped membrane structure at the center of the cell. The plant cell also has several cell organelle structures performing a variety of functions to main...
Androecium, the male reproductive whorl of flower, is composed of stamens. A stamen (= microsprophyll) is made up of chiefly two parts: a large terminal portion, anther, and a stalk known as the filament. Each anther consists usually of two lobes connected together by a suture known as...
It is these differences in plant cell make up that allows the plant to be such a successful sessile organism, for example it is the rigidity provided by the cellulose containing cell walls that give many plants the strength and support to grow to vast heights. The turgidity of a plants cel...
