Female part of the flower is called _______.

A
Stamen

B
Pistil

C
Pollen tube

D
Petal

Solution

In a flower, the female reproductive part is known as the pistil. It is made up of three parts that include an ovary, style, and stigma. So, the correct answer is option B.
Question 2
1 / -0

Plants that are shorter than trees and have a bushy appearance are called ____________.

A
Short trees

B
Shrubs

C
Herbs

D
Grasses

Solution

A shrub is a woody plant having a low height. It has several branches that arise from the base and give it a bushy appearance. Shrubs provide a variety of fragrant flowers, berries, etc.
Question 3
1 / -0

State the order in which various parts of flower are arranged from outer side to inner side.

A
Carpel $$\rightarrow$$ Stamen $$\rightarrow$$ Petals $$\rightarrow$$ Sepals

B
Sepals $$\rightarrow$$ Petals $$\rightarrow$$ Stamen $$\rightarrow$$ Carpel

C
Petals $$\rightarrow$$ Sepals $$\rightarrow$$ Stamen $$\rightarrow$$ Carpel

D
Sepals $$\rightarrow$$ Petals $$\rightarrow$$ Carpel $$\rightarrow$$ Stamen
Solution
Four parts of a flower are arranged in rings inside each other from the outer side to the inner side.
- Sepal - Protect the flower in the bud. It is often green.
- Petals - Brightly colored in insect-pollinated plants. It is small or non-existent in wind-pollinated plants.
- Stamen - The male part of the plant which produces the pollen.
- Carpel - The female part of the plant which produces fruit once pollination has taken place.
Thus, the correct answer is (B).
Question 4
1 / -0

Which one of the following is the male part of a flower?

A
Stamen

B
Stigma

C
Egg

D
Pollen tube
Solution
- Stamen is the male reproductive part of the flower. It has anther and filament. Anther of stamen produces pollen grains that contain male gametes.
- Stigma is a part of female reproductive structure of flower i.e. carpel.
- Egg is female gamete while pollen tube help in transfer of male gamete into the embryo sac.
So, the correct answer is option A.
Question 5
1 / -0

Which of the following process in the plants is responsible for the release of oxygen?

A
Respiration

B
Digestion

C
Photosynthesis

D
Reproduction
Solution
- Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. Carbon dioxide, water and light are all needed for photosynthesis to take place.
- During photosynthesis, the plant uses the energy of sunlight and convert carbon dioxide and water into carbohydrates and oxygen. Thus, oxygen is released during photosynthesis.
So, the correct answer is 'Photosynthesis'.
Question 6
1 / -0

Phenomenon which convert light energy into chemical energy is:

A
Respiration

B
Photosynthesis

C
Transpiration

D
Metabolism

Solution

$$\textbf{Correct answer:}$$ Option B

$$\textbf{Explanation for correct answer:}$$
Option B
$$\bullet$$ Light energy is converted into chemical energy by the photosynthesis process.
$$\bullet$$ Chemical energy is used by the cells as a fuel for the various life process.

$$\textbf{Explanation for incorrect option:}$$
Option A- Respiration is extracting the energy from the food that is stored in the body.

Option C- Loss of water through the stomata is known as transpiration.

Option D- Metabolism converts stored energy into the life force.

$$\textbf{Conclusion:}$$ Plants are the major faction that can do photosynthesis.
Question 7
1 / -0

To survive, all plants needs _________.

A
Roots, leaves and stems

B
Light, soil and nutrients

C
Food, water and air

D
Eyes, nose and ears
Question 8

A
Microscopic pores in leaves

B
Small porous roots

C
Flowers

D
Seeds
Question 9
1 / -0

Which of the following lists all the ingredients and products of photosynthesis?

A
Carbon dioxide, water, oxygen and carbohydrate

B
Phosphorus, nitrogen, water, carbon dioxide and oxygen

C
Carbohydrates, water, nitrogen and carbon dioxide

D
Carbon dioxide, water, ozone and carbohydrates.
Question 10
1 / -0

The medium-sized plants which grow to a height of 8 -9 feet are called ______.

A
Shrubs

B
Herbs

C
Trees

D
Long trees
Solution
