6. Which of the following is a dry fruit?__________

Answer-(1- Lamina, 2-Leaf, 3-Stigma, style and ovary,4-Mango, 5-Onion, 6-Walnut)

Icse class 6 biology question answer of plant life

B. Give reasons for the following statements.

1. Insectivorous plants get nutrition by digesting insects.

Answer- Insectivorous plants are generally present in areas where soil is not rich in nutrition. Thus, they get their food by eating and digesting insects caught in a trap formed by modified leaves.

2. Hibiscus is a complete flower.

Answer- A complete flower is a flower that has all the four whorls present i.e calyx, corolla, androecium and gynoecium. Hibiscus is a complete flower since it shows the presence of these whorls mentioned above. Apart from that hibiscus has both male and female reproductive structure that has petals, sepals, stigma, pistil and a receptacle that makes it a complete flower.

3. Stigma is a disc-like expanded part.

Answer- stigma is a female reproductive part of a flower and its disc-like expanded part because it receives pollen grains from pollinators (bees) during pollination.

4. In plants, agents are required to transfer pollen grains.

Answer- we know that plants can’t move from one place to another. Hence it requires some agents for pollination that will transfer pollen grains from one flower to another.

5. Flowers that produce nectar are pollinated by bees.

Answer- flowers that produce nectar are pollinated by bees because the nectar produces a sweet smell that attracts bees, hence pollination occurs.

C. Answer in short.(Icse class 6 Biology chapter 1 solution)

1. What is the role of leaf tendril?

Answer- leaf tendril gives support to the plant to climb up, as it coils around it and helps the plant to climb.

2. Name different arrangements of leaves around the stem.

Answer- The different arrangements of leaves around the stem are:

1. alternate

2. opposite and

3. whorled

3. What are the functions of fruit?

Answer- The functions of fruit are:

1. it protects seeds from harsh climatic conditions.

2. helps in the dispersal of seeds.

3. stores food material.

4. Define germination.

Answer- the process by which the dormant embryo within the seed becomes active and grows into a new plant is called germination.

5. What are the agents of pollination?

Answer- The different agents of pollination are:

1. wind

2. water

3. insects and

4. animals

6. What is a zygote?

Answer- a zygote is the cell formed when two gametes (male and female gametes) fuse together during fertilization.

AT LENGTH-Icse class 6 Biology chapter 1 solution

A. Explain the following terms.

1. Leaf 2. Venation 3. Insectivorous plants 4. Gynoecium 5. Pollination

Leaf– a leaf is a thin, flat and generally green outgrowth which develops from the node present in the stem. a bud is usually present in the axil of a leaf, called the axillary bud which grows into a new plant. a leaf has the following main parts:

1. leaf blade.

2. leaf stalk or petiole

3. midrib

4. leaf base

Venation- venation is the arrangement of veins and veinlets on the lamina of a leaf. it is of two types:-

1. reticulate venation

2. parallel venation

Insectivorous plants- Insectivorous plants generally depend upon small insects, because they grow in areas where the soil is not rich in nutrition. In order to obtain nutrition, their leaves are modified into different types of structures such as pitcher or bladder for catching and digesting insects. Example- Pitcher plant and Venus flytrap

Gynoecium- Gynoecium is the innermost whorl of the flower. The main function of Gynoecium is producing and protecting the ovules and helping in pollination. It is the female reproductive part of the flower that consists of the carpel or pistil. A Carpel or Pistil has three parts:-

1. Stigma

2. Style and

3. Ovary

Pollination – The process of transfer of pollen grains from the anther of a flower to the stigma of the same flower or another flower of the same species is called pollination. Pollination is the first step in the formation of seeds. Pollination is of two types:-

1. Self-pollination

2. Cross-pollination

icse class 6 biology chapter 1 notes

B. Differentiate between the following.

1. Simple leaf and compound leaf

2. Reticulate venation and parallel venation

3. Self-pollination and cross-pollination

4. Monocot seeds and dicot seeds

Simple leaf

There is a single leaf blade or lamina in a simple leaf that is completely undivided.
Cuts may be present but do not reach up to the midrib.
Example-banana, mango, Guava

Compound leaf

Ina compound leaf the leaf blade or lamina is divided into many small parts called leaflets.
They don’t have any auxiliary buds
Example- Neem, Acacia, Rose plant

Reticulate venation

In reticulate venation, the veins and veinlets are irregularly distributed over the entire lamina that interconnects with each other like a web or network.
in this type of venation, the midrib connects the leaf.
Example- Peepal, Guava, mango etc

Parallel venation

In parallel venation, all the veins of a leaf are parallel to each other from the base of the leaf to the tip of the leaf.
Example- Banana, Grass, Wheat

Self-pollination

When pollen grains are transferred from anther to the stigma of the same flower or different flower of the same plant, it is called self-pollination.

Cross- pollination

When pollen grains are transferred from the anther of a flower to the stigma of a flower on another plant but of the same species is called cross-pollination.

Monocot seeds

The monocot seeds have a single cotyledon which means in monocot there is only one seed leaf present inside the seed coat.
in monocot seed, the leaves have parallel venation.
Example- Garlic, onions, rice, corn

Dicot seeds

The dicot seeds have a pair of cotyledon which means in dicot there is two seed leaf present inside the seed coat. In dico
t seed, the leaves have reticulate venation.
Example-Beans, Pea, Cauliflower
