What is an example of fibrous root system?
A fibrous root system forms a dense network of roots that is closer to the soil surface. An example of a tap root system is a carrot. Grasses such as wheat, rice, and corn are examples of fibrous root systems.
How can roots be identified?
Perhaps the most striking characteristic of roots that distinguishes them from other plant organs such as stem-branches and leaves is that roots have an endogenous origin, i.e., they originate and develop from an inner layer of the mother axis, such as pericycle.
What is function of fibrous root system?
The fibrous roots are thin, with root hairs, and their function is mainly absorption of plant nutrients and water from soil. When the plant grows further, several fleshy roots of indefinite growth are produced from the lower nodes of the mother ginger rhizome and primary fingers.
Is it possible for you to find out whether a plant has taproot or fibrous root?
Yes, we can find out whether a plant has tap root or fibrous roots by looking at the impression of its leaves on a sheet of paper. If the leaf has parallel venation, then it is likely to have fibrous root but if the leaf has reticulate venation then the plant will have tap root.
Which among the following will have fibrous roots?
Plants which have fibrous root are: wheat, maize, grass, banana, bamboo, etc.
Can you find a plant in your house or in your neighborhood?
Answer. Answer: Yes, the money plant in my house and in my neighborhood has a long but weak stem.
What type of Venation do its leaves likely to have?
If a plant has fibrous roots, what type of venation do its leaves likely to have? Solution: The leaves of plants with fibrous roots have parallel venation.
Is it possible to know the type of roots of a plant without pulling it out from the soil explain?
Yes, ‘it is possible’ to find whether a ‘plant’ has ‘fibrous’ or ‘tap root’ by ‘looking’ at the ‘leaf impression on paper. ‘ Explanation: If the leaf is having a parallel venation, that root of the plant will be fibrous root and if the leaf is having reticulated venation, that root of the plant will be a taproot.
In which part of flower ovary is found?
Is a stigma male or female?
The male parts of the flower are called the stamens and are made up of the anther at the top and the stalk or filament that supports the anther. The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen.
What is Epigynous ovary?
Definition. Referring to a flower in which all or some of the floral parts (i.e., the sepals, petals, and stamens) arise from the summit of the ovary; e.g., species of Asteraceae and Rubiaceae.
What are the three types of ovary?
There are three categories: hypogynous, perigynous, and epigynous. (a) hypogynous, if sepals, petals and stamens are attached to the receptacle below the ovary. The ovary in this case is said to be superior.
In which family do we find a Gynobasic style?
Gynobasic style is when the style originates from the mid basal part of the ovary. The style arises from a central depressed part or cavity of the ovary. It is seen in Salvia, Ocimum. Gynobasic style is the feature of the Labiatae family or mint family.
How does ovary become fruit?
When a grain of pollen reaches the stigma, it creates a pollen tube for the sperm to journey down the style and fertilize the ovule; fertilized ovules become seeds. Fertilization is the death of the flower, as the petals drop or wither at this point and the ovary starts to enlarge and ripen into what we know as fruit.
What comes first fruit or flower?
Each fruit starts with a flower. Then four separate events will take place in sequence. They are pollination, fertilization, growth and development, and, finally, ripening. First comes the pollinator.
What happens to flower after fertilization?
After fertilization, the flower loses its shine. After fertilization four major changes that take places are development of endosperm and embryo, development or maturation of ovules into seeds and formation fruit from ovary.
What type of fruit is a banana?
Bananas are both a fruit and not a fruit. While the banana plant is colloquially called a banana tree, it’s actually an herb distantly related to ginger, since the plant has a succulent tree stem, instead of a wood one. The yellow thing you peel and eat is, in fact, a fruit because it contains the seeds of the plant.

Did you know that some of the nuts, fruits and vegetables we consume are not natural? Yes, you got that right! Some are indeed man-made. These are man-made hybrids created through a selective breeding process in which only favourable plants with good characteristics are replanted to reproduce and become food.
Do real bananas still exist?
Edible bananas are the result of a genetic accident in nature that created the seedless fruit we enjoy today. Virtually all the bananas sold across the Western world belong to the so-called Cavendish subgroup of the species and are genetically nearly identical.
Why do bananas not taste good anymore?
When you break down the artificial banana flavor, it comes down to one compound: isoamyl acetate. According to a BBC story on this topic, if you were to sniff isoamyl acetate (like the cool kids did behind the bleachers) you would say “that’s bananas!” But, you know, in the literal sense.
Are bananas radioactive?
Some potassium is always taken in via the diet, and some is always excreted, meaning that there is no buildup of radioactive potassium. So, while bananas are indeed radioactive, the dose of radioactivity they deliver does not pose a risk.
Can you eat the end of a banana?
It’s much more common to just eat the whole thing, peel included. The black bit doesn’t do them much harm. The reason people peel banas is because the fruit inside is much tastier than the peel an the texture is much more pleasant.
