Answers:
1.)
Solution: a) Plants
Commonly, the organisms which contain green pigment or chlorophyll are referred to as Plants. Hence, organisms that contain chlorophyll are known as Plants.
2.)
Solution: a) Phylogenetic classification is the classification of organisms based on their evolutionary history and Relationships.
3.)
Solution: b) Cuscuta
Kingdom plantae include few members of insectivorous plants and parasites. Cuscuta is an example parasitic plant or parasite because it takes food material from the host and do not contain chlorophyll.
4.)
Solution: a) Chlorophyll, thalloid. Algae uses chlorophyll to trap light energy and facilitates photosynthesis whereas its body structure resembles a thallus so it is thalloid also.
5.)
Solution: d) It includes fungi.
‘It includes fungi’ is not a characteristic of kingdom plantae because it do not contain chlorophyll and it depend on other organisms for food.
6.)
Solution: b) Multicellular. The bryophyte sex organs are called multicellular because they produces a multicellular sporophytic body.
7.)
Solution: b) Main producers
Plants mainly uses sunlight, nutrients, water, etc. and produces their own food which is a unique feature. Hence, kingdom plantae belong to plants and plants are main producers on land water.
8.)
Solution: a) Liverworts, mosses. The bryophytes are divided into liverworts and mosses. These are smaller sized plants that prefer to grow in shady and damp areas.
9.)
Solution: c) Carbohydrates
All the plants do contain chlorophyll. Chlorophyll is used to synthesis carbohydrates as well as it releases oxygen in the air.
10.)
Solution: a) Cellulose. The cell wall composition in chlorophyceae is cellulose which provides structural and mechanical support to the cell.
11.)
Solution: a) Two
Both Cryptogamae and Phanerogamae are sub kingdoms of kingdom plantae. Hence, two sub kingdoms are present under kingdom plantae.
12.)
Solution: d) Flagella absent. In Rhodophyceae there is no flagella present. Only green algae and brown algae.
13.)
Solution: c) Seed plants
Phanerogamae include visible special reproductive structures and are seed producing plants. Hence, seed plants are commonly called as Phanerogamae.
14.)
Solution: d) Both (a) & (b). Agar is produced by Gracilaria and Gelidium. Agar is mainly used from these source because it is of higher quality and it works as better raw material.
15.)
Solution: a) Rhodophyceae group of algae are also known as Red algae.
‘Rhodophyceae group of algae are also known as Red algae’ is a correct because it is based on the photosynthetic pigment. Chlorophyceae group is known as Green algae and Phaeophyceae is known as brown algae.
16.)
Solution: a) Brown algae includes a filamentous form called as Ectocarpus which is easily cultivable. These filaments can attach itself and grow on variety of lab equipments.
17.)
Solution: d) All of them
Group Chlorophyceae include green algae. Examples of Chlorophyceae are Chara, Spirogyra and Chlamydomonas.
18.)
Solution: d) 100 metres. Kelps can grow upto 100 metres of height because they live in turbulent water which brings new supplies of nutrients regularly.
19.)
Solution: a) Equisetum
In the Pteridophytes, leaves may be simple and sessile in lycopodium and large pinnately compound in ferns. Leaves of Equisetum may be scaly in the Pteridophytes.
20.)
Solution: a) Volvox is an algae that undergoes Haplontic lifecycle zygotes are only diploid cells whereas mitosis occurs only in the haploid phase. The individuals produced due to mitosis are called haplonts.
21.)
Solution: b) Absence of cambium
Cambium layer is mainly responsible for secondary growth. Pteridophytes do not have cambium. Hence, secondary growth is not observed in the Pteridophytes.
22.)
Solution: d) All of the above plant kingdom includes algae, bryophytes, gymnosperms etc because they also have chlorophyll like plants and does photosynthesis similar to plants.
23.)
Solution: a) Haploid
Without fusion of female and male gametes, development of sporophyte takes place. Hence, sporophyte is haploid in Apogamy.
24.
Solution: a) Mesophyll cells contain chlorophyll pigment responsible for photosynthesis and these mesophyll cells are present in leaves.
25.
Solution: d) Leaf, Stem and Bulbil
Given diagram shows unknown parts where one part is a leaf, second is stem and third round like part is a Bulbil.
26.
Solution: a) Sporopollenin makes the pollen grain preserved as fossil because it is resistant to heat, strong acids and alkali. There is no enzyme till now discovered that can degrade Sporopollenin.
27.
Solution: d) Gymnosperms
The gymnosperms found less in living form and more in fossilized form. Hence, gymnosperms are also known as Living fossils.
28.
Solution: d) Rhizoids anchors the growing body of bryophytes to the substratum and is capable of nutrients absorption required for the growth.
29.
Solution: d) All of them
Parts of plant that we can eat are referred to as Edible parts of plant. The edible parts of plants are flowers, stems, roots, leaves, tubers, fruits and seeds.
30.
Solution: c) Parthenocarpy. Partheno means without fertilization and carpy means fruit. So parthenocarpy is used for those fruits which are form without the fertilization.
