Test: Animals and Plants - 2 - CTET & State TET MCQ

Root usually grows under the ground while shoot usually grows above the ground. The shoot has different parts called the stem, leaves, flowers and fruits. The stem is the stalk of the plant.

The plant parts like root, stem, and leaves are called vegetative parts because they have the power of growing asexually without getting involved in the process of reproduction. These do not contain any germ cells (sexually reproducing cells) but still are capable of giving rise to young plants by vegetative propagation. New shoot and root germinate from nodes and adventitious buds. Plants raised by vegetative propagation can bear flowers and fruits earlier than those produced from seeds.

Root usually grows under the ground while shoot usually grows above the ground. The shoot has different parts called the stem, leaves, flowers and fruits. The stem is the stalk of the plant.

Correct option is D. Marigold

Trunk: Strongest part of the tree providing the support for the rest of the tree.

There are some plants with weak stems that cannot stand upright and spread on the ground. These are called creepers, while those that take support on neighbouring structures and climb up are called climbers. These are different from the herbs, shrubs and trees.

Parts of the Stem

All stems of the angiosperms, including those which are highly modified, are recognizable from other plant organs by their presence of nodes, internodes, buds and leaves. A node is a point on the stem from which leaves or buds arise. The portion between two successive nodes is the internode.

A bud is an embryonic stem which has the potential for further plant growth. It may develop into a leaf, flower, or both. Such buds are called leaf buds, flower buds and mixed buds, respectively. Many buds remain dormant within a certain duration or they may be embedded in the stem tissue as to become hardly visible. A single bud that is found at the apex of the stem is called terminal bud while lateral buds or axillary buds occur in the leaf axils, the upper angle between the stem and leaves. As a result of injury, adventitious buds may be formed also in the internode of the stems, in leaves, or roots. The “eyes” of the potato tuber are buds.

The correct option is C.
Tomato, wheat, paddy, grass and bananas are a few examples of herbs.

Apical dominance in plants is the main stem of the plant, spurting with growth from its bud, due to the growth hormone called auxin.

Trunk: Strongest part of the tree providing the support for the rest of the tree.

The male sex cells of seed plants (flowering plants, conifers, and cycads) are contained in tough capsules called POLLEN. Pollen grains are produced by organs called anthers and must be transferred to the female parts of plants in order to form seeds. This process, called pollination, can be achieved in various ways. Some plants are assisted by animals that act as POLLINATORS. 

The male sex cells of the seed plants or flowering plants are contained in tough capsules, called as pollen. Pollen grains are produced by male organs, anthers or stamens.

Thus, the correct answer is option (A), 'Anther'.

Onion is one among the family of plants,with modified stem. The onion bulb is the modified stem,which is used for eating. If the plant as a whole is observed then one can find roots at the lower end while leaves can be seen on the other end,in green onions.

Roots are mainly of two types: tap root and fibrous roots.
Plants having leaves with reticulate venation have tap roots while plants having leaves with parallel venation have fibrous roots.

Plants with weak stem that cannot stand upright and spread on the ground are called Creepers. Examples: Pumpkin, Watermelon, mint, sweet potato, etc. 

Apical dominance in plants is the main stem of the plant, spurting with growth from its bud, due to the growth hormone called auxin.

Carpel is the female reproductive organ of a flower, consisting of an ovary, a stigma, and usually a style. It may occur singly or as one of a group.

The gynoecium (whether composed of a single carpel or multiple "fused" carpels) is typically made up of an ovary, style, and stigma as in the center of the flower.

Coleus or Solenostemon species are generally bright with vibrant leaf colours. They are sturdy growers, although some of the seed varieties are less robust than those propagated by vegetative means. They are often used in landscaping as they stand out in a bedding scheme due to their bright foliage.

• Flowers: They hold the plant's baby-making parts and aid in pollination, where pollen reaches the eggs for fertilization.
• Fruits: They come from a flower's ripe ovary, housing seeds. Fruits help seeds spread for new plant growth.
• Seeds: These are baby plants' beginnings with all the genetic details for future growth. They often travel with the help of wind, animals, or water.
• In contrast, roots, stems, and leaves are about plant support, growth, and food-making through photosynthesis.

Embryo or baby plant: It is present inside the seeds which develop into a new plant. The embryo gives rise to a baby shoot (plumule) and root (radical).
