Questions 1. Name the following:
(i) Groups of plants included under Kingdom Plantae
Ans– bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).
(ii) Two bryophytes
Ans– Hornworts, liverworts, and mosses are all examples of bryophytes.
(iii) Two pteridophyte
Ans– Selaginella and Salvinia
(iv) Two gymnosperms
Ans– pine, yew,
(v) Three dicot plants
Ans– Legumes (pea, beans, lentils, peanuts) daisies, mint, lettuce, tomato and oak
(vi) Three monocot plants
Ans– tulips, onions, garlic
Questions 2. Give one word for the following :
(i) Simplest land plants which lack vascular tissues. Bryophytes
(ii) First land plants with vascular tissues. Pteridophytes
(iii) Naked-seeded plants. conifers,
(iv) Vascular tissue-bearing plants. …………
(v) Plants having a single cotyledon in their seeds. monocotyledons or monocots.
Questions 3. Distinguish between the following:
(i) Bryophyta and Pteridophyte
Bryophytes: Bryophytes are embryophytes that do not possess a true vascular tissue.
Pteridophytes: Pteridophytes are vascular plants that reproduce via spores.
(ii) Gymnosperms and Angiosperms
difference between angiosperms and gymnosperms is how their seeds are developed. The seeds of angiosperms develop in the ovaries of flowers and are surrounded by a protective fruit. Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers.
(iii) Dicots and Monocots
The monocots consist of one seed leaf, which is called the cotyledon, while the dicots are made up of two embryonic leaves. In fact, the names of the classes are based on the seed leaf it produces, which is Monocotyledonae or one cotyledon and Dicotyledonae or two cotyledons.
Questions 4. Choose the correct answer from the options given below:
(i) The plant body is not differentiated into root, stem and leaves, in
(a) Bryophyta
(b) Thallophyte
(c) Tracheophyte
(ii) The simplest land plants fall under
(a) Pteridophyte
(b) Gymnosperms
(c) Bryophyta
(iii) Cotyledons are also called
(a) Seed leaves
(b) Baby plant
(c) Seed coat
(iv) Cycas and pine are placed under
(a) Angiosperms
(b) Gymnosperms
(c) Bryophytes
Questions 5. Match the items in Column A with those in Column B:
| Column A | Column B |
| (a) Green alga | (i) Cycas |
| (b) Bryophyte | (ii) Onion |
| (c) Pteridophyte | (iii) Mango |
| (d) Gymnosperm | (iv) Ulva |
| (e) Dicot plant | (v) Moss |
| (f) Monocot plant | (vi) Fern |
Answer :
Match the items in Column A with those in Column B:
| Column A | Column B |
| (a) Green alga | (iv) Ulva |
| (b) Bryophyte | (v) Moss |
| (c) Pteridophyte | (vi) Fern |
| (d) Gymnosperm | (i) Cycas |
| (e) Dicot plant | (iii) Mango |
| (f) Monocot plant | (ii) Onion |
Questions 6. Give the important characteristics of the following groups of plants:
(i) Algae– Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Algae can be multicellular or unicellular. Unicellular algae occur most frequently in water, especially in plankton.
(ii) Bryophytes– The plant body is thallus like, i.e. prostrate or erect. It is attached to the substratum by rhizoids, which are unicellular or multicellular. They lack true vegetative structure and have a root-like, stem-like and leaf-like structure. Plants lack the vascular system.
(iii) Pteridophytes– They are seedless.They are multicellular.They reproduce through spores.They are independent and free-living organisms.They have a well-differentiated plant body into root, stem and leaves.
(iv) Gymnosperms– They are naked, found in colder regions where snowfall occurs, develop needle-like leaves. They are perennial or woody, forming trees or bushes.
(v) Angiosperms– Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds.
Questions 7. You are given a number of different plants. How would you identify a particular plant as:
(a) an alga– Algae are photosynthetic organisms. Algae can be either unicellular or multicellular organisms. Algae lack a well-defined body, so, structures like roots, stems or leaves are absent. Algaes are found where there is adequate moisture. Reproduction in algae occurs in both asexual and sexual forms.
(b) a moss– They are small flowerless plants that grow in dense clumps or mats, generally in damp or shady places. Each plant is usually made up of a simple, one-cell-thick leaf attached to a stem. Gametophytes is the term used for the low, leaf-like form of moss and sporophytes the tall, stalk-like forms.
(c) a fern– Ferns are plants that do not have flowers. Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves.
(d) a dicot plant– Dicots have flower parts in multiples of fours or fives like the five-petaled dicot flower pictured to the right.
