Tomatoes , aboriginal to Central , South and North America , are members of the Solanum lycopersicum family . tomato grow on two types of plants : determinate and undetermined . Determinate varieties grow to a specified height and produce one round of fruit each season . undetermined plant life grow and produce fruit throughout the time of year until the first frost . look on diversity , tomatoes can be crimson , livid , orangish , icteric , brown or purpleness and form several form , admit round , heart cherry and oblong .

Roots

Tomato plants form different rootage systems depending on the method of propagation . Seed - found Lycopersicon esculentum train a taproot system , consist of a strong central root that shoot late into the dirt and smaller sidelong roots that rise out of the principal root , near the top of the root . love apple grow from cuttings develop a stringy root scheme , comprised of a series of small , stringy roots that organise a horizontal matting near the soil logical argument .

Stems and Branching

The root word forms a terminal bud at the tip and lateral leg that form from a coiling pattern of nodes along the distance of the stem . The prow , branches and foliage are comprised of vascular bundle that carry wet and nutrient to the works and develop fruit . As the tomato plant ages , the theme becomes woody and fibrous but keep the vascular system to extend give the flora . Pruning change the social organization of the industrial plant by causing an step-up in lateral branch yield .

Foliage

Tomato foliage , ranging from light immature to dreary blue - green in color , is composed of chemical compound leaves that form on the lateral subdivision of the plant . While variety show see the ultimate shape and size of the leaves , glandular trichomes ( midget hair ) cover all foliation , branches and stems and secrete a light-green - chicken substance that let out the biting " tomato " odour and leave behind sticky residue when touched .

Flowering

Flowers work on the branches in simple or complex patterns depending upon pruning activity . Many gene pretend the number of blooms produced , including temperature , nutrient and wet levels . Tomato flowers , pallid to bright yellow in color , are typically less than one inch in diameter . Classified as thoroughgoing flower , tomato efflorescence have both male and female organ , five longsighted flower petal , and the ovary that will finally form the yield . In order for yield to form on the plants , pollenation must be initiated , manually or through the assistance of insects and wind .

Fruit

After successful pollination , tomato flowers wither and fall away to expose the swelling ovary . yield set forth out small , firm and bright green in people of color . They observe the immature food coloring until the fruit has form its final shape and sizing , at which point the people of colour of the flesh and skin start to change until it make its final chromaticity , indicating ripeness .
