Short Answer Questions: 3 Marks

Differentiate Between:

2. Reticulate venation and parallel venation

Ans: Differences between reticulate venation and parallel venation are as follows:

Reticulate Venation	Parallel Venation
Veins are distributed in a network-like pattern on both sides of the midrib.	Veins are parallel to midrib throughout the leaf.
Midrib is very prominently visible.	Midrib is not well distinguished.
This kind of venation is seen in taproot system plants like mango, datura etc.	This type of venation is found in fibrous system plants like grasses.

3. Tap root and fibrous root

Ans: Differences between tap roots and fibrous roots are as follows:

Tap Roots	Fibrous Roots
Tap roots refers to the main root and its branches.	Fibrous roots refers to the fine hair-like roots.
Tap roots develop from the redicle which is the embryonic root.	Fibrous roots develop from stem or leaves.
Tap roots grow vertically deep into the soil.	Fibrous roots are short and most of them grow horizontally in the soil.
Examples: Mango Tree, Rose Plant.	Examples: Grasses.

4. Stem and root.

Ans: Differences between stem and roots are as follows:

Stem	Root
It grows outside soil which keeps a plant upright.	It grows inside the soil.
Leaves, branches, and flowers grow from stem.	It is spread inside the ground and holds the plant upright.
It absorbs water from the root and takes it to other parts of the plant.	It absorbs water from the soil.

5. Sepal and Petal

Ans: Differences between sepals and petals are as follows:

Sepal	Petals
Sepal is small and green leaf like structure outside the flower	It can be large or small. They are colourful and have a pleasant smell.
It protects the bud from external harm.	It is present inside the sepals and attracts pollinators.
A flower without sepals is known as asepalous.	A flower without petals is known as apetalous.

6. Creepers and climbers

Ans: Differences between creepers and climbers are as follows:

Creepers	Climbers
Plants with fragile stems that don't need to be supported.	Plants with weak stems that can only stand upright with the assistance of external support.
Spread throughout the ground.	It grows in an upward direction.
Example: Watermelon, Pumpkin etc.	Example: Money plant, Cucumber etc.

Long Answer Questions: 5 Marks

7. Compare herbs, shrubs and trees.

Ans: Difference between herbs, shrubs and trees are following:

	Herb	Shrubs	Trees
Plant Height	Small and close to the ground.	Moderate Height	Very Tall
Stem	Stems are weak, green and herbaceous	Stems are hard, upright and woody	Stems are very hard, thick and woody
Branch	Present all around the stem.	Present at the base of the stem.	Appears at top of the stem
Function	Used as seasoning in food and have medicinal values.	Shrubs also have medicinal values and are used in gardening.	Prevent soil erosion, wood for fire and furniture etc.
Example	Wheet, Paddy, Tomato, Mustard etc.	Lemon, Tulsi, Rose etc.	Neem, Mango, Sheesham, etc

8. Explain the function of the leaf.

Ans: Leaf is a thin, broad green structure arising from nodes of the stem.

Photosynthesis is the primary function of the leaf. Plants use sunlight to create compounds that are used as food in a process known as photosynthesis. Only particular green pigments known as chlorophyll can trap sunlight. Chlorophyll absorbs sunlight and converts carbon dioxide and water into glucose, which serves as nourishment. Presence of chlorophyll also makes the leaves green in colour.
Another structure called stomata is present on the leaf surface which helps in exchange of gases i.e. respiration.
In addition, the leaves serve as a means of transpiration. The loss of water as water vapour from aerial portions of plants, such as leaves, is known as transpiration. Transpiration aids in the cooling of the plant. It's also crucial for the root's water absorption.
In some plants like Bryophyllum, leaves also help in reproduction through vegetative propagation.
Leaves also store food in some plants. E.g. Aloe.

FAQs on Important Questions for CBSE Class 6 Science Chapter 4 - Getting to Know Plants

1. Why are plants important to us, according to Chapter 4 Class 6 Science?

Plants play a huge part in keeping the ecosystem alive. Plants are very important to us. They help us survive as they provide oxygen to us. Plants are important to help humans survive. Apart from providing us with oxygen, plants are a source of food for a few animals in this world. Plants are also important to us as they help us to reduce the air pollutants in the air. This in turn protects humans and animals.

2. Why did Rima find small leaves in the sprouts according to Chapter 4 Class 6 Science?

Rima soaked some gram seeds for sprouting. However, she forgot about it and she remembered on the fifth day. When she went to open the box of seeds that had the sprouts she noticed there were tiny leaves that were growing out of the seed along with the white structure of the sprout. A gram plant generally has a taproot. Therefore, since the seeds were soaked in water for quite a few days, the gram seeds germinated into tiny plants.

3. Do all leaves have petioles according to Chapter 4 Class 6 Science?

Petioles refer to the stock that helps to join a leaf to its stem. However, not all leaves have petioles in them. There are a few leaves that have petioles in them that help the leaves to attach themselves to the stem. While, at the same time, there are a few leaves that do not have petioles in them. Instead, these leaves are said to be directly attached to the stem of the plant. For example, Celery leaves have petioles while sessile leaves don't have petioles.

4. What are the parts of a flower as discussed in Chapter 4 Class 6 Science?

The main parts of a flower include

Pedicel: Refers to the flower's stalk
Thalamus: It refers to the swollen uppermost part of a pedicle.
Sepal: It is the green protective outgrowths of the Thalamus
Pistil: The flower's female part is known as Pistil. It consists of style, ovary, and stigma.
Stamen: The flower's male part is known as Stamen. It consists of an Anther.
Carpel: It is shaped like a flask and is available in the middle of the flower attached to the stalk.

5. How do plants make their own food as discussed in Chapter 4 Class 6 Science?

Plants don't have a digestive system. Therefore, with the help of photosynthesis plants make their own food. The roots of plants soak up all the minerals and water from the ground. Their leaves absorb a gas known as carbon dioxide from the air. Plants transform sunlight, water, and carbon dioxide into simple sugars and oxygen. This process is known as photosynthesis. This is used as a fuel for plants. The foods produced are called starch and glucose.
