Parts of Plants and their Structure – Maharashtra Board Class 6 Solutions for General Science (English Medium)
MathematicsGeneral ScienceMaharashtra Board Solutions
Solution 1:
S.No | A | B | |
(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 |
Solution 2:
- 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.)
Solution 3:
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.
Solution 4:
- calyx : sepals
corolla : petals
- leaf apex : tip of the leaf
leaf margin : edge of the leaf
Solution 5.a:
Difference between calyx and corolla:
S.N0 | Calyx | 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. |
Solution 5.b:
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. |
Solution 6:
- Lateral roots, root hair, root tip and root cap
- Node, internode, axillary and terminal buds and branches
- Node
- Leaf blade or lamina, leaf margin, leaf apex, mid-vein, veins, leaf base, stipule and petiole
- Stipule
- Stalk, thalamus, calyx, corolla, androecium and gynoecium
- Calyx
Solution 7:
- 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.
Solution 8.a:
The parts of a plant are root, stem, leaf, flower and fruit.
Solution 8.b:
Root hair are hair-like fibres present at the tip of the root.
Solution 8.c:
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.
Solution 8.d:
The pointed tip of the leaf lamina is called the leaf apex or leaf tip.
Solution 9.a:
Parts of the root:
Solution 9.b:
Parts of the stem:
Solution 9.c:
Parts of a leaf:
Solution 9.d:
Parts of a flower:
