Class 6 Science Chapter 7 MCQ

Tap root is the main root and the smaller side roots are called “lateral roots”. Anther is a part of stamen. The visible part of bud are the sepals. Leaf perform three main functions i.e. photosynthesis, transpiration and respiration.

Photosynthesis is not the primary function of stem. It is a function of leaves. Whereas, conduction of water and minerals from roots to other parts, formation of branches, bearing flowers and fruits and holding the plant upright are main functions of a stem.

The plants can be classified into three main group, as herbs, shrubs and trees.

Here, all the statements are correct. Hence, your answer will be option [D].

Creeper: Creeper is a plant having thin, long and weak stem, which cannot stand upright and spreads on the ground. Example – Money plant. The rest can be corrected as: Shrub: Hard Woody stem with branching near the base. Example – Jasmine. Tree: Hard thick woody stem with branching much above the ground on the stem. Example – Banyan, Neem. Herb: Non-woody, soft delicate, green tender stem. Examples – Sunflower, Tomato.

The stem of a tree is the strongest part of the tree and it is known as trunk. Most of the tree trunks are covered with a layer called bark. Bark protects the inner parts of a tree.

The stem of a plant is the link between the roots and the rest of the plant. In a tree, generally stem support the branch and hold the leaves.

A large number of veins spread out. The mid-rib and veins consists bundles of tiny tubes, some of which carry water into the leaf and others carry away the food from the leaf.

Here, all the statements are correct. Hence, your answer will be option [D].

Here, all the statements are correct. Hence, your answer will be option [D].

Grass has parallel venation in leaves (veins run parallel to one another on both sides of the mid rib) and fibrous root system (bunch of similar size fibre like roots).

The pollen grains contain male sex cells of a plant, not female cells. Rest of all statements are correct. Hence, your answer will be option [D].

Here, all the statements are correct. Hence, your answer will be option [D].

The ovules contain female sex cells of a plant, not male cells. Rest of all statements are correct. Hence, your answer will be option [C] as incorrect.

Most of the plants bear flowers, they are called flowering plants. Some of the examples of flowering plants are sunflower plant, rose, mango, grass, lemon, wheat, chilli, tomato, tulsi, potato, sugarcane etc. Some of the plants, do not bear flowers, they are called non-flowering plants. Some of the examples of non-flowering plants are pine trees, mushrooms or fungi, ferns, algae, etc.

Examples of herbs are tomato, mustard, turnip, radish, rice, cabbage, carrot, ginger etc. Examples of shrubs are lemon, henna, pomegranate, china rose, tulsi, croton, jasmine, rose etc. Here, all the statements are correct except option [D]. Hence, your answer will be option [D].

The Pistil or carpel is the female part of a flower. It is made up of three parts as: Stigma: Top part of Pistil. It is sticky and receives Pollen. Style: Middle part of pistil. It is a tube that connects stigma to ovary. Ovary: Swollen part at the bottom of pistil that contains ovules.

The fibrous roots spread out in the soil and they can give firm support to the plant as taproots. Roots are referred as anchor of a tree which provide firm and rigid support to the plant in the soil.

The stem of a tree is the strongest part of the tree and it is known as trunk. Most of the tree trunks are covered with a layer called bark. Bark protects the inner parts of a tree.

Grass has parallel venation in leaves (veins run parallel to one another on both sides of the mid rib) and fibrous root system (bunch of similar size fibre like roots).

Example – Banyan, Neem. Herb: Non-woody, soft delicate, green tender stem. Examples – Sunflower, Tomato.

Roots absorb water find minerals from the soil. Stem conduct food from leaves to other parts of the plant.

Photosynthesis is the process by which leaves prepare food. Sunlight, Carbon dioxide, Chlorophyll and Water are necessary for it. The other sentences can be corrected as: Oxygen is released (not absorbed) during this process and carbohydrates (not proteins) are made during photosynthesis.

Here, all the statements are correct. Hence, your answer should be option [D].
