Parts of Plants and their Structure – Maharashtra Board Class 6 Solutions for General Science (English Medium)
|(a)||root||3.||growing from radicle|
|(b)||part of stem between nodes||4.||internode|
|(c)||stem||2.||growing from plumule|
|(d)||bud||1.||stem grows in height|
- Root hair (Root hair are hair-like fibres present at the tip of the root, whereas the node, internode and bud are found on the stem.)
- Leaf apex (The leaf apex is the tip of the leaf, whereas the calyx, corolla and gynoecium are parts of a flower.)
Root cap – Located at the tip of the root.
Root hair – Located at the tip of the root.
Stalk – Located at the joint where the flower is attached to the stem.
Veins – Located inside the leaf lamina on the midrib of leaves.
Thalamus – Located at the base of the flower.
- calyx : sepals
corolla : petals
- leaf apex : tip of the leaf
leaf margin : edge of the leaf
Difference between calyx and corolla:
|1.||The calyx is made up of sepals.||The corolla is made up of petals.|
|2.||It is generally green in colour.||It has a variety of colours and fragrances.|
|3.||It is the outermost whorl of a flower.||It is the second whorl of a flower between the calyx and gynoecium|
|4.||It protects the flower in the bud stage. It also protects the inner whorls of the flower in the later stages.||It attracts the insects with its colourful petals and fragrance. The insects bring about pollination in the flower.|
Differences between hibiscus leaf and peepul leaf:
|S.N0||Hibiscus leaf||Peepul leaf|
|1.||There is a thin midrib in the centre of the lamina of the hibiscus leaf.||There is a thick midrib in the centre of the lamina of the peepul leaf.|
|2.||Small veins and veinlets arrange themselves parallel in the lamina giving a parallel venation.||Smaller veins and veinlets form a network in the lamina giving a reticulate venation.|
|3.||Leaf margin of hibiscus leaf is serrated.||Leaf margin of peepul leaf is plain.|
|4.||Leaf apex does not taper and is shorter.||Leaf apex is tapering and pointed.|
|5.||Hibiscus leaf has stipules.||Peepul leaf does not have stipules.|
- Lateral roots, root hair, root tip and root cap
- Node, internode, axillary and terminal buds and branches
- Leaf blade or lamina, leaf margin, leaf apex, mid-vein, veins, leaf base, stipule and petiole
- Stalk, thalamus, calyx, corolla, androecium and gynoecium
- The edge of the leaf is called the leaf margin.
- The androecium is made of stamens.
- The flat part of a leaf is called the lamina or leaf blade.
- The corolla is the group of petals.
- The innermost whorl of the flower is the gynoecium.
The parts of a plant are root, stem, leaf, flower and fruit.
Root hair are hair-like fibres present at the tip of the root.
A bud is an undeveloped shoot. It is a projection on the stem, generally green in colour, from which a branch of the stem, a leaf or a flower develops. On a plant, the bud is found on the stem at two places:
- An apical bud is found at the apex of the stem and causes an increase in the height of the stem.
- An axillary bud is found in the axil of the stem and may develop into a flower or a branch.
The pointed tip of the leaf lamina is called the leaf apex or leaf tip.
