As with all organisms , a tomato ’s basal objective is to reproduce and extend on its inherited line . Every component of the plant ’s anatomy is designed to reach this destination . Roots seek out urine and nutrients , which the semi - woody main radical carries through vascular tissue to the leaves , flush and developing fruit . The great compound leaves capture the vitality of the sun to fuel the growing plant , which opens promising yellow flowers that attract the attending of passing insects . Once cross-pollinate , the sexual organs of the flowers develop into yield , housing the seeds of the next tomato generation .
Roots
Most plants have one of two character of tooth root organisation , either a fibrous origin system or a taproot system . Taproot system have a larger , primal beginning from which all the other belittled theme in the system spring up . unchewable systems are more complex , with branching root which are all more or less the same diam in size . Lycopersicon esculentum can have either of these root systems ; plant life grown from germ ordinarily have a taproot scheme , where plants get from film editing have fibrous root systems .
Stem
The main automobile trunk of the tomato industrial plant is be of three part . The first , the shoot apical meristem ( SAM ) , is the actively produce destiny located at the pennant of the plant . The second portion consists of principal tissue , newly grown stem just behind the SAM . All other radical - wood is refer to as junior-grade tissue , or old growth . As the SAM grows up , the lowly tissue paper grow outwards , expanding the lower vascular tissue to keep up with the tomato ’s increasing weewee and alimental necessity .
Leaves
The leaves of a tomato works are compound ; that is , each branch arising from the master stalk consists of a leaf , and leaflets grow along that key stem , or rachis . Where this branch attaches to the trunk of the Lycopersicon esculentum plant is known as the petiole ; the stem where each cusp bond to the rachis is call the petiolule . Additionally , each leaflet can itself be a compound foliage , with minuscule leaflet arising along the stem before terminating in a enceinte primary pamphlet at the end of this limb .
Flowers
Tomato industrial plant produce yellow flowers ( usually less than 1 inch in diameter ) that feature an inner , coalesced stamen surrounded by a corolla of out petal . The green distaff reproductive carpel sit within the cylindrical yellow out stamen , which farm pollen to fertilize the distaff organs . After fertilisation , the carpels tumefy to develop into the tomato yield .
Fruit
Cutting open a ripe tomato fruit , the observer see two or more internal chamber where seeds are housed , case in a gelatinous mountain ; surrounding these chambers is a denser fleshy material that is protect overall by a smooth outer wall . The interior sleeping accommodation are know as locular cavities , and the dense material that encloses these cavities is the placental tissue paper . Nearer to the hide of the tomato are the vascular bundle , which carry weewee and nutrient to the interior of the fruit , which are enclosed in the pericarp , or outer flesh of the tomato .
