NCERT Solutions For Class 6 Science Chapter 7 Getting to Know Plants

In the flower, ovary is found in the swollen and lowermost part of the pistil.

In plants, food is produced in leaves by the process of photosynthesis.

Plants having leaves with reticulate venation will have tap roots.

If a plant has fibrous root, the venation present in its leaves is parallel.

Yes, the type of roots can be determined by looking at the impression of the plant leaf on a paper. If the impression of the leaf shows reticulate venation, that is, if there is a net-like impression on both the sides of midrib, then the plant has taproots. However, if the impression of the leaf shows parallel venation, then the plant has fibrous roots.

Flowers with joined sepals are: China rose and tomato.

Flowers with separate sepals are: Rose and jasmine.

All the plants mentioned here bear flowers. Plants like grass, tulsi and peepal bear very small flowers.

The leaves that have reticulate venation are tulsi, coriander (dhania) and China rose.

In our house or in our neighbourhood, the plant found with a long but weak stem is money plant. This plant can be classified as a climber because it takes support on its neighbouring structures and climb up.

Functions of stem in a plant are:

  1. The stem provides support to the plant.

  2. It conducts water and minerals from the roots of the plant to its leaves and various other parts.

  3. It also transports food prepared in leaves to other parts of the plant.

(a) a leaf of rose plant

(b) taproot of rose plant

(c) a flower of rose plant

(a) Roots absorb water and minerals from the soil.
(b) Stem holds the plant upright.
(c) Stem conducts water to the leaves.
(d) The number of petals and stamens in a flower may not be always equal.
(e) If the sepals of a flower are joined together, its petals are separate and are not joined together.
(f) If the petals of a flower are joined together, then the pistil is not necessarily joined to the petal.
